Mercedes-AMG SL, R 231, 2015

The legend – now even more dynamic

Stuttgart.  New appearance for an automotive icon: the technically and visually optimised Mercedes-Benz SL will be on the road from April 2016.

More powerful engines, the 9G-TRONIC automatic transmission, DYNAMIC SELECT with five transmission modes and Active Body Control with the curve tilting function all take the legend to a new dynamic level.     

Its suitability for everyday use has been enhanced with the hard top, which can now be operated at up to 40 km/h when starting off, and the automatic boot separator.

Visually the front end in particular has been made significantly sportier and includes a new bonnet, new bumpers and new headlamps.

The Mercedes-Benz SL is the top performer in a wide variety of disciplines: an elegant roadster for relaxed, comfortable cruising or a dynamic coupé for sporty trips on winding roads.

Ola Källenius, Member of the Board of Management of Daimler AG, Mercedes-Benz Cars Sales & Marketing: “Only the SL delivers such a unique blend of driving pleasure: a pure, sporty roadster feeling or relaxed, comfortable cruising.

Mercedes-AMG SL, R 231, 2015

It’s a dream car that fulfils its owner’s wishes with technical perfection.”

A particularly eye-catching feature of the new SL is the revised front: The unique diamond radiator grille extends downwards.

Mercedes-AMG SL, R 231, 2015

Two powerdomes accentuate the long, drawn-out bonnet. Also adding to the unmistakable new appearance of the SL is the new standard-fit LED Intelligent Light System with headlamp housing extending far to the outside.

The sporty silhouette is emphasised by the enlarged cosmetic air outlets with wing-like chrome inserts in the dynamic, broad vehicle wings and the exterior mirrors positioned on the beltline.

Mercedes-AMG SL, R 231, 2015

“The sporty design of the new SL with its progressive front end and the aesthetic silhouette emphasise its unique character.

Through its sensual purity, the car defines our top-class standards when it comes to modern luxury,” says Gorden Wagener, Vice President Design Daimler AG.

The model range comprises the SL 400 with a V6 engine uprated to 270 kW(367 hp) and 500 Nm (additional 25 kW/35 hp and also 20 Nm) as well as the SL 500 with a powerful 335 kW (455 hp) V8 engine boasting a peak torque of 700 Nm.

Mercedes-AMG SL, R 231, 2015

As standard the power transfer is handled by the new 9G-TRONIC nine-speed automatic transmission.

With DYNAMIC SELECT the vehicle characteristics can be adjusted in seconds at the touch of a button, as the system modifies the setup of the engine, transmission, suspension and steering at the driver’s behest.

Mercedes-AMG SL, R 231, 2015

Additional variants include the two Mercedes-AMG models in the guise of the SL 63 and SL 65, the latter with a V12 engine.

Intelligent Drive: Driving Assistance package Plus and LED Intelligent Light System

As standard the SL features Active Brake Assist, known as COLLISION PREVENTION ASSIST PLUS in other model series.

In addition to radar-based proximity warning and braking assistance by Adaptive Brake Assist, this Active Brake Assist system carries out autonomous braking to reduce the danger of rear-end collisions.

Optionally available for the SL is the Driving Assistance package Plus with stereo camera and in some cases new as well as improved functions. Features of the Driving Assistance package Plus at a glance:

  • Distance Pilot DISTRONIC with Steering Pilot: assists the driver with maintaining a safe distance from the vehicle in front and staying in the centre of the lane.
  • Active Brake Assist with cross-traffic function: is able to warn the driver of impending crash situations, provide optimum support with emergency braking and if necessary also automatically apply the brakes itself.
  • Active Blind Spot Assist: is able to warn the driver when changing lanes, for example, and can contribute to averting an impending collision by means of one-sided brake actuation.
  • Active Lane Keeping Assist: can detect unintentional departure from the lane and intervene with corrective action.
  • PRE-SAFE® PLUS: if a rear-end collision appears imminent, the system can activate preventive measures to protect occupants.
  • The optional Parking Pilot can take the strain off the driver by helping them to search for a suitable parking space and making it easier to manoeuvre into and out of parking spaces with active steering intervention.

For optimum visibility on country roads and motorways, when cornering and on bends, the standard-fit LED Intelligent Light System automatically adapts to all light and driving conditions.

The LED technology features low energy consumption, a long service life and a pleasant white light which approximates the daylight spectrum.

The five functions of the LED Intelligent Light System include motorway mode, cornering light function, camera-based active light function, roundabout light function and also the enhanced fog light function. Anti-dazzle continuous high beam comes courtesy of the optional Adaptive Highbeam Assist Plus.

When high beam is switched on, this system always makes the optimum headlamp range available.

The driver can concentrate on the traffic and does not have to continually switch between low beam and high beam.

Mercedes-AMG SL, R 231, 2015

Comfort appointments: more convenient operation of the vario-roof

SL fans also appreciate the sports car icon on account of its high suitability for everyday use. With the facelift Mercedes-Benz has improved the comfort appointments even further.

These include operation of the electrohydraulic vario-roof. If when opening or closing the roof the vehicle has to move off due to the traffic conditions, the process which was started when at a standstill can be continued up to a speed of approx. 40 km/h.

Equally new is the exclusive automatic boot separator. If the separator is in the upper position for increased boot capacity, it automatically moves down when the top is opened.

Conversely, the automatic boot separator returns to the upper position, also by means of electric operation, as soon as the boot lid is opened.

Mercedes-Benz SL. MAGIC VISION CONTROL

A further special feature comes in the guise of MAGIC VISION CONTROL, the intelligent and highly efficient wash/wipe system.

In this system, the washer fluid is always delivered immediately in front of wipe lip, via the water feed line integrated into the blade – and it does this in both wiping directions.

Optionally the wiper can be heated to prevent snow or ice from sticking in winter. Details like this underline the positioning of the Roadster Coupé as a comfortable sports car for all seasons.

Mercedes-AMG SL, R 231, 2015

Connectivity: Mercedes me connect featuring a host of functions

The new SL is intelligently networked and “always on”. This is ensured thanks to the standard-fit communications module (on-board SIM card) which enables the use of Mercedes me connect services.

The available Standard Services currently include Accident Recovery, Breakdown Management and Maintenance Management, as well as Telediagnostics, for example.

Also available as standard is the Mercedes-Benz emergency call system.

If the Remote Online option is specified, navigation destinations, for example, can be sent to the vehicle from a computer or smartphone.

Further remote and tracking services include Geofencing, Vehicle Tracker, Parked Vehicle Locator, Remote Door Locking and Unlocking, and Remote Retrieval of Vehicle Status.

Mercedes-AMG SL, R 231, 2015

With the Smartphone Integration package, compatible smartphones can be integrated into the vehicle via Apple® CarPlay® and used via voice-operated control for example. Safe and comfortable use on the road is always ensured.

The functionality of COMAND Online (optional extra on the SL 400) now includes Live Traffic Information, for example.

This service uses real-time traffic data for dynamic route guidance with more accurate arrival times. Internet radio is standard for all SL models.

The atmosphere is like that of a concert hall, even when the roof is open, thanks to the Frontbass system, which had its world premiere in the SL in 2012.

It takes up less installation space in the doors by making use of the aluminium cavities in front of the footwell as resonating chambers for the bass speakers.

Mercedes-AMG SL, R 231, 2015

More choice: curve tilting function for the ABC suspension for the first time

The steel suspension of the standard chassis features continuously variable dampers. In conjunction with the AMG Line equipment the suspension is lowered by 10 mm and fitted with harsher springs and torsion-bar stabilisers.

The driver can leave the setting of the basic characteristics of the suspension to the control electronics via DYNAMIC SELECT – from comfortable to extremely sporty in the third Sport Plus mode.

Alternatively there is another option available in the guise of Active Body Control (ABC) with curve tilting function (not for AMG versions).

ABC reduces body movements when moving off, braking and cornering. The spring struts of the ABC suspension are adjusted to the respective driving conditions via so-called plunger cylinders (by oil pressure), therefore making torsion-bar stabilisers on the front and rear axle, which can hamper comfort, unnecessary.

The dampers only have to eliminate wheel vibrations and can be set up in a such a way as to ensure comfort without losing any of the sportiness.

Mercedes-AMG SL, R 231, 2015

In addition, the vehicle level can be adjusted to any unevenness: At higher speeds the SL is automatically lowered by 13 mm for more favourable aerodynamics.

Conversely, at the touch of a button it is possible to raise the vehicle by 50 mm for driving on rough roads.

On top of this there is the curve tilting function which applies a maximum of 2.65 degrees in the speed range from 15 to 180 km/h.

It can be set via DYNAMIC SELECT (“Curve”), noticeably reducing the effects of lateral acceleration on the vehicle occupants. The DYNAMIC SELECT transmission modes in conjunction with ABC suspension:

  • Curve (CV) increases ride comfort
  • Comfort (C) is the comfortable setting for long journeys or on rough roads
  • Sport (S) as a sporty setting enables a particularly dynamic driving style
  • Sport Plus (S+) is an extremely sporty setting – particularly suitable for flat road surfaces; tuning of the ESP® characteristics is likewise more sporty in this mode
  • Individual (I) allows individual adjustment of the various parameters to suit the driver’s requirements

Mercedes-AMG SL, R 231, 2015
Elaborate all-aluminium bodyshell

The latest generation of the Mercedes-Benz SL takes the meaning of the well-known abbreviation “SL” – Super-Light – literally at its word.

Systematic weight reduction is just as much a part of the outstanding design features of the new SL as it was for its namesake, the original SL from 1952 with its lightweight tubular frame.

Here for the first time Mercedes-Benz has implemented an all-aluminium bodyshell as part of large-scale series production.

Only relatively few components are made using other materials. High-strength steel tubes are integrated in the A-pillars to increase safety.

The aluminium bodyshell weighs around 110 kg less than if it had been produced using steel technology. The aluminium structure is not only lighter, but also superior in terms of rigidity, safety and comfort.

Mercedes-AMG SL, R 231, 2015

Tradition: a dream sports car for more than 60 years

The exceptional position occupied by the SL in the history of Mercedes-Benz is also evident from its very name: due to its iconic status, the SL has retained its tradition-rich model designation even after the introduction of the new nomenclature.

For more than 60 years now, the Mercedes-Benz model range with the “SL” acronym has enthralled sports car fans around the world.

Mercedes-AMG SL, R 231, 2015

Design: Intelligently re-engineered exterior and interior

New appearance for the athletic aesthete

The Mercedes-Benz SL has always been athletic and aesthetic at the same time. Now the designers have worked on bringing these characteristics even more to the fore.

A particularly eye-catching feature is the revised front end of the new-edition SL: traditional elements have been further developed with confident style for the new appearance.

Mercedes-AMG SL, R 231, 2015

The new SL likewise embodies top-class standards on the inside.

Inspiration for the front-end design came from the legendary 300 SL Panamericana racing car with its steeply raked radiator grille.

This extends downwards, thus creating a completely individual “face” for the SL within the Mercedes-Benz model range. The grille is executed as the diamond radiator grille as standard.

Mercedes-AMG SL, R 231, 2015

The sculpted shape of the radiator grille harmonises perfectly with the now standard AMG bodystyling with the front apron in an A-wing design, which features a front splitter in the vehicle colour.

Two powerdomes on the bonnet invoke the sporting heritage of the SL, while light-catching contours give additional structure to the bonnet.

Mercedes-AMG SL, R 231, 2015

Also adding to the unmistakable new appearance of the SL are the new standard-fit LED Intelligent Light System with headlamp housing extending far to the outside, the torch-shaped unit comprising the daytime running lamp/position lamp and direction indicator, and the extraordinary light show that greets the driver on approaching the car.

Mercedes-AMG SL, R 231, 2015

The edge area and other design components of the headlamp housing are retained in black – conveying a high-level of perceived quality and an effective sense of depth.

The side view of the SL reveals iconic sports car proportions, characterised by the long bonnet, the AMG side sill panels, the broad wheelbase and passenger compartment positioned towards the rear.

Fine details create additional highlights. These include enlarged cosmetic air outlets with wing-like chrome inserts in the dynamic, broad vehicle wings.

Mercedes-AMG SL, R 231, 2015

With the roof down the SL shows off its attractive roadster contours with short, steeply angled A-pillars and frameless side windows.

There is nothing to disrupt the clear lines: all aerials, as well as the roll-over bar, are fully integrated and thus not visible, while the electric draught-stop (optional extra) can be extended and retracted at the push of a button.

Mercedes-AMG SL, R 231, 2015

The rear end points to the high driving dynamics of the SL. The basis for this is the sense of width created by the large track gauge, accentuated by the AMG rear apron with side air outlets.

The lower section of the diffuser incorporates the integral tailpipe trim elements as well as the centrally arranged rear fog lamp and reversing light.

Coloured all in red, the broad one-piece tail lamps take up the side lines and draw them round into the rear end.

As is typical of the brand, they feature a horizontal design with the wedge-shaped direction indicator at the top and the tail lamp and also brake lamp below.

Brilliant blue and designo selenite grey magno are available to choose from by way of new colours, plus the range of light-alloy wheels in the size 48.3 cm (19 inches) has also been extended significantly.

Mercedes-Benz SL, R 231, 2015

New additions include a 10-spoke wheel and a 5-spoke wheel, both with a high-sheen finish in high-gloss black. On top of this there are six additional new AMG wheels as part of the accessories range.

One new individualisation option is the AMG Night package (in conjunction with the AMG Line) comprising front splitter, diffuser inserts in the rear apron and exterior mirror housings, each in high-gloss black, plus 19-inch AMG 7-twin-spoke light-alloy wheels painted in high-gloss black with a high-sheen finish.

“The SL’s new design with the inverted radiator grille was inspired by the original SL and emphasises its uniqueness in the Mercedes-Benz product portfolio,” explains Gorden Wagener, Vice President Design Daimler AG.

Mercedes-AMG SL, R 231, 2015

Interior design: sports car atmosphere in comfortable surroundings

Minimal gap dimensions and fully padded beltlines are just two examples of the top-class standards which the SL also embodies in the refined interior.

The ambient lighting with three selectable colours (solar red, polar blue, polar white) ensures an emotional lighting mood.

The upper part of the dashboard forms a unit with the door beltlines, and four round air vents featuring an engine look create sporty highlights.

Mercedes-Benz SL, R 231, 2015

The three-spoke sports steering wheel has a magnesium structure and features an ergonomic grip area and a high-quality finish.

The airbag module too is finished in nappa leather with topstitching. Twelve control buttons provide access to the menu navigation in the instrument cluster as well as the audio system, telephone and voice entry.

The steering wheel rim has a flattened bottom section, and silver-coloured steering wheel shift paddles enable manual gear changes to be made.

Mercedes-Benz SL, R 231, 2015

The instrument cluster with 2-tube look for displaying speed and rpm combines classic circular instruments with modern display technology.

Dials and pointers have a sporty new design. Up to 60 km/h, the speed scale is indicated in steps of 10. When starting up, the pointers move from the 6 o’clock position once around the entire scale and then return to the starting position.

The driver is also greeted in style by the multifunction display located between the circular instruments: on start-up it shows a front view of the SL.

Mercedes-Benz SL, R 231, 2015

Lovingly designed details such as the analogue clock (optional extra) adorn the centre of the dashboard. Its new graphic design is based on the instrument cluster.

Depending on the transmission mode selected by DYNAMIC SELECT, the media display presents dynamic driving data: longitudinal and lateral acceleration (in a G-force cross) or torque and output.

Comprehensive individualisation of the interior is possible with the broad selection of leather finishes and trim elements.

The colour saddle brown is new in combination with nappa leather and Exclusive nappa leather.

Mercedes-Benz SL, R 231, 2015

Comfort appointments: More convenient operation of the vario-roof

More suitable for everyday use than any other roadster

SL fans also appreciate the sports car icon on account of its high suitability for everyday use. With the facelift Mercedes-Benz has improved the comfort appointments even further, including operation of the electrohydraulically powered vario-roof and the new automatic boot separator.

Operation of the practical vario-roof, which transforms the SL into either a roadster or a coupé, has been further enhanced.

If when opening or closing the roof the vehicle has to move off due to the traffic conditions, the process which was started when at a standstill can be continued up to a speed of approx. 40 km/h.

Mercedes-Benz SL, R 231, 2015

Equally new is the automatic boot separator. If the separator is in the upper position for increased boot capacity, it automatically moves down when the top is opened.

Conversely, the automatic boot separator returns to the upper position, also by means of electric operation, as soon as the boot lid is opened.

Another practical boot feature retained from the predecessor model is the loading setting, which allows the roof stowed in the boot to be swung upwards by approximately 25 degrees.

The KEYLESS-GO Convenience package includes remote closing of the boot lid as well as HANDS-FREE ACCESS.

With this, the lid opens or closes automatically after making a kicking motion with the foot beneath the rear bumper.

The automatic boot separator additionally moves into the upper position when opening the lid to provide clear access to the loading aperture.

Mercedes-Benz SL, R 231, 2015

Another feature which has been retained is the unique optional extra MAGIC SKY CONTROL: when closed, the panoramic vario-roof automatically changes from dark to transparent or vice-versa within just a few seconds at the push of a button.

When it comes to ambient lighting, Mercedes-Benz has opted for LED technology and has adapted the colour range: in addition to solar red, the colours polar blue and polar white can also be chosen.

A further practical finishing touch: the stowage compartment in the centre console now features two USB ports. One of the highlights is ambient lighting with projection of the brand logo.

A further special feature comes in the guise of MAGIC VISION CONTROL, the intelligent and highly efficient wash/wipe system.

Mercedes-Benz SL, R 231, 2015

In this system, the washer fluid is always delivered immediately in front of wipe lip, via the water feed line integrated into the blade – and it does this in both wiping directions.

The result is that there is no gush of water when spraying fluid, which can impair visibility, and at the same time the maximum cleaning effect is achieved.

In addition, the water stays on the windscreen, thus also enabling convenient cleaning even with the roof open. The water is delivered even more precisely when the roof is open.

Optionally the wiper can be heated to prevent snow or ice from sticking in winter. Details like this underline the positioning of the Roadster Coupé as a comfortable sports car for all seasons.

Mercedes-Benz SL, R 231, 2015

Drive system: Biturbo engines and 9G-TRONIC

Power and efficiency

Sophisticated V-engines with twin turbochargers ensure high output and impressive pulling power – transferred to the road smoothly and efficiently by the new 9G-TRONIC automatic transmission.

Now uprated by 25 kW for the SL 400, the V6 biturbo with a displacement of three litres comes from the M276 engine family and features the BlueDIRECT injection and combustion system.

Cylinder heads and block are made of aluminium. To reduce friction, the cylinder barrels are coated with the aid of the innovative NANOSLIDE process.

Other engine characteristics include four valves per cylinder, a particularly quiet chain drive system with silent chains and two camshaft adjusters each for the intake and exhaust sides.

Mercedes-Benz SL, R 231, 2015

The car is equipped with a direct coil ignition system.

The third-generation direct injection system has a fuel pressure of 200 bar and spray-guided multiple injection with piezo injection nozzles.

The on-demand vane-type oil pump cools and lubricates the engine depending on engine load and engine speed.

The volume control distinguishes between a low and a high pressure level and adjusts the volume flow as required.

The weight of the components of the water circuit was reduced through the specific use of plastic. In an extended temperature range the heating supply for the interior is preferentially served.

Mercedes-Benz SL, R 231, 2015

The desired temperature is thus very quickly reached during the warm-up phase.

Despite the different cylinder angle (90° vs. 60°), the M278 series V8 engine in the SL 500 is closely related to the six-cylinder unit.

The crankcase, pistons and cylinder heads are likewise made of aluminium, while the injection and combustion process follow the same principle.

Here, too, the Mercedes-Benz engineers have achieved high performance with good drivability, particularly thanks to the use of one exhaust gas turbocharger per cylinder bank.

New 9G-TRONIC nine-speed automatic transmission: comfort and efficiency

The 9G-TRONIC, being used in the SL for the first time, is a highly efficient transmission. The broad ratio spread of 9.15 for gears one to nine allows a clearly perceptible reduction in engine speed and is a decisive factor behind the high level of energy efficiency and ride comfort.

Mercedes-AMG SL, R 231, 2015

Shortened shift and response times ensure optimum immediacy combined with outstanding ease of shifting.

In manual mode and S mode in particular, the 9G-TRONIC responds significantly more spontaneously than the previous transmission and enhances driving pleasure. Plus it has a ‘sailing’ function in E mode.

Mercedes-AMG SL, R 231, 2015

The particular ease of shifting of new 9G-TRONIC comes courtesy of a comprehensive package of measures.

These include the novel direct control system which enables short, barely perceptible gear changes. The combination of twin-turbine torsional damper and centrifugal pendulum technology in the torque converter ensures outstanding drive comfort.

Together with the extended gear ratio spread, higher speeds can now be driven at lower engine speeds for even greater comfort.

A further focus of transmission development was “compact lightweight construction”. Despite two additional gears and a maximum transferable torque of up to 1000 newton metres, the new automatic transmission requires as little installation space as its predecessor and is also lighter in weight.

The two-piece housing design has been retained: the torque converter housing is made of lightweight aluminium, while the transmission housing with weight-optimised plastic oil pan is made of an even lighter magnesium alloy.

Nine gears are implemented with a minimal number of planetary gear sets and shift elements: only four simple planetary gear sets and six shift elements are necessary.

Three speed sensors monitor operation and provide the transmission control system with corresponding data for effective shifting.

It is possible for several gears to be jumped when accelerating or decelerating, should the driving conditions call for it.

To ensure the reliable and at the same time energy-efficient supply of long-lasting and shear-resistant, second-generation synthetic fuel economy engine oil, the new automatic transmission is equipped with two pumps.

The considerably smaller mechanical main pump, featuring an off-axis design, is located next to the main shaft and is chain-driven and fed by a separate electric auxiliary pump.

This design enables the flow of lubrication and coolant to be controlled actively on demand and also means that the 9G-TRONIC can benefit from a start/stop system.

Thanks to the world’s first direct control system in a planetary automatic transmission with nine gears, it has also been possible to significantly increase hydraulic efficiency within the transmission.

The higher number of gears and the broader gear ratio spread help to increase drive comfort and allow a significant enhancement to be achieved in terms of engine power conversion.

Mercedes-AMG SL, R 231, 2015

Suspension: Curve tilting function for the first time

The driver determines the suspension characteristics

The desired mode is selected using DYNAMIC SELECT, which is available in conjunction with the standard-fit steel suspension or the optional Active Body Control (ABC).

The curve tilting function is available with the ABC suspension for the SL for the first time.

The steel suspension of the standard chassis features continuously variable dampers. In conjunction with the AMG Line equipment the suspension is lowered by 10 mm and fitted with harsher springs and torsion-bar stabilisers.

The driver can leave the setting of the basic characteristics of the suspension to the control electronics via DYNAMIC SELECT – from comfortable to extremely sporty in the new Sport Plus mode. The characteristics of the transmission modes:

  • Eco (E), fuel-efficient setting with ‘sailing’ function
  • Comfort (C), comfortable setting for long journeys or on rough roads
  • Sport (S), sporty setting for a dynamic driving style
  • Sport Plus (S+), extremely sporty setting – particularly suitable for flat road surfaces; tuning of the ESP® characteristics is likewise more sporty in
    this mode
  • Individual (I) allows individual adjustment of the various parameters to suit the driver’s requirements

Alternatively there is another option available in the guise of Active Body Control (ABC) with curve tilting function.

ABC reduces body movements when moving off, braking and cornering. The spring struts of the ABC suspension are adjusted to the respective driving conditions via so-called plunger cylinders (via oil pressure), therefore making torsion-bar stabilisers on the front and rear axle, which can reduce comfort, unnecessary.

The dampers only have to eliminate wheel vibrations and can be set up in such a way as to ensure comfort without losing any of the sportiness.

In addition, the vehicle level can be adjusted to any unevenness: At higher speeds the SL is automatically lowered by 13 mm for more favourable aerodynamics.

Conversely, at the press of a button it is possible to raise the vehicle by 50 mm for driving on rough roads.

On top of this there is the curve tilting function (not for AMG models) which applies a maximum of 2.65 degrees in the speed range from 15 to 180 km/h.

It can be set via DYNAMIC SELECT (“Curve”), noticeably reducing the effects of lateral acceleration on the vehicle occupants. The DYNAMIC SELECT transmission modes in conjunction with ABC suspension:

  • Curve (CV) increases ride comfort
  • Comfort (C) is the comfortable setting for long journeys or on rough roads
  • Sport (S) is a sporty setting that allows a particularly dynamic driving style
  • Sport Plus (S+) is an extremely sporty setting – particularly suitable for flat road surfaces
  • Individual (I) allows individual adjustment of the various parameters to suit the driver’s requirements

Body

Elaborate all-aluminium bodyshell

On the current SL, for the first time Mercedes-Benz has implemented an all-aluminium bodyshell as part of large-scale series production. Only relatively few components are made using other materials.

The latest generation of the Mercedes-Benz SL takes the meaning of the well-known abbreviation “SL” – Super-Light – literally at its word. Systematic weight reduction is just as much a part of the outstanding design features of the new SL as it was for its namesake, the original SL from 1952 with its lightweight tubular frame.

Here for the first time Mercedes-Benz has implemented an all-aluminium bodyshell as part of large-scale series production.

Only relatively few components are made using other materials. High-strength steel tubes are integrated in the A-pillars to increase safety.

Mercedes-AMG SL, R 231, 2015

The aluminium bodyshell weighs around 110 kg less than if it had been produced using steel technology. The aluminium structure is not only lighter, but also superior in terms of rigidity, safety and comfort.

This is thanks to intelligent lightweight construction with components optimised for their respective intended purposes.

For example, different types of aluminium processing are used. Depending on their function, the components are produced using gravity die casting or vacuum die casting, made from extruded sections or used as aluminium sheets of a variety of different wall thicknesses.

These measures result in high levels of rigidity and safety as well as enhanced vibration characteristics.

With its intelligent lightweight construction, which also comprises new bonding techniques, the SL has also become a role model for the current S-Class.

The total of six models in the luxury class are characterised by a high percentage of strategically deployed light alloys such as aluminium or magnesium.

Mercedes-AMG SL, R 231, 2015

Safety: Intelligent Drive

Assistance in all driving situations

With the Driving Assistance package Plus (option), the driver can relax even while driving in stop-and-go traffic, as the Distance Pilot DISTRONIC with Steering Pilot assists by keeping the car a safe distance behind the vehicle in front and in the centre of the lane.

The LED Intelligent Light System, fitted as standard, ensures the best possible visibility conditions regardless of the light and driving conditions.

As standard the SL features Active Brake Assist, known as COLLISION PREVENTION ASSIST PLUS in other model series.

Mercedes-AMG SL, R 231, 2015

In addition to radar-based proximity warning and braking assistance by Adaptive Brake Assist, this Active Brake Assist system carries out autonomous braking to reduce the danger of rear-end collisions.

If the driver fails to act when a risk of a collision is detected, despite the warning lamp in the instrument cluster and the intermittent audible alert, the system will initiate automatic braking.

This significantly reduces the vehicle speed. At low relative speeds, this intervention may be sufficient to prevent a rear-end collision with slower-moving, stopping or stationary vehicles.

Optionally available for the SL is the Driving Assistance package Plus with stereo camera and in some cases new as well as improved functions. Overview of the features of the Driving Assistance package Plus:

  • Distance Pilot DISTRONIC with Steering Pilot: assists the driver with maintaining a safe distance from the vehicle in front and staying in the centre of the lane. The radar and camera-based system brakes when necessary and accelerates again, if possible, to the preset desired speed. The Steering Pilot can take the strain off the driver when it comes to lateral guidance of the vehicle. On straight roads and gentle curves it generates steering torque which contributes to keeping the vehicle in the centre of the lane. To achieve this the system makes use of a stereo camera to orient itself based on clearly visible road markings and, at lower speeds,
    on the vehicle in front.
  • Active Brake Assist with cross-traffic function: is able to warn the driver of impending crash situations, provide optimum support with emergency braking and if necessary also automatically apply the brakes itself. In addition to detecting slower-moving, stopping or stationary vehicles, it also detects crossing traffic at junctions, the tail ends of traffic jams and pedestrians in the danger zone ahead of the vehicle, for example. The PRE‑SAFE® Brake is able to detect not only slower-moving, stopping or stationary vehicles but also pedestrians, to brake autonomously if the driver fails to react and as a result help to avoid accidents up to 50 km/h and reduce their severity up to 72 km/h. In flowing traffic, the PRE-SAFE® Brake provides assistance according to the same mode of operation throughout the speed range from 7 to 200 km/h.
  • Active Blind Spot Assist: is able to warn the driver when changing lanes, for example, and can contribute to averting an impending collision by means of one-sided brake actuation.
  • Active Lane Keeping Assist: is able to detect unintentional lane departure, warn the driver by means of pulsating steering wheel vibrations and contribute, by means of one-sided brake actuation, to guiding the vehicle back into its lane.
  • PRE-SAFE® PLUS: if a rear-end collision appears imminent, the system can activate preventive measures to protect occupants. These include warning vehicles following behind and applying the vehicle brakes when at a standstill.

The optional Parking Pilot can take the strain off the driver by helping them to search for a suitable parking space and making it easier to manoeuvre into and out of parking spaces with active steering intervention.

Mercedes-AMG SL, R 231, 2015

A new feature is assistance with parking perpendicular to the road. The Parking Pilot includes six ultrasonic sensors in each of the front and rear bumpers which measure the size of the parking space when driving past it.

In addition, the Parking Assist PARKTRONIC is also a part of the system. It provides visual and audible warnings of obstacles in front of and behind the vehicle, thus helping to avoid damage when manoeuvring.

LED Intelligent Light System: Outstanding visibility in all conditions

Mercedes-AMG SL, R 231, 2015

For optimum visibility on country roads and motorways, when cornering and on bends, the standard-fit LED Intelligent Light System automatically adapts to all light and driving conditions.

The LED technology features low energy consumption, a long service life and a pleasant white light which approximates the daylight spectrum.

The five functions of the LED Intelligent Light System include motorway mode, cornering light function, camera-based active light function, roundabout light function and also the enhanced fog light function.

On unlocking the SL, the welcome light also greets the driver with an exceptional lighting display: the LED fibre optics in the headlamps light up in blue after opening the vehicle and then transition to white locator lighting.

Anti-dazzle continuous high beam comes courtesy of the optional Adaptive Highbeam Assist Plus. When high beam is switched on, this system always makes the optimum headlamp range available.

Mercedes-AMG SL, R 231, 2015

The driver can concentrate on the traffic and does not have to continually switch between low beam and high beam.

Via a camera positioned behind the windscreen, the Adaptive Highbeam Assist Plus detects other illuminated road users, for example oncoming vehicles or vehicles travelling in front, and adjusts the headlamps independently to the new traffic conditions.

A mechanism in the headlamp module masks the portion of the cone of light of the LED headlamps where there are other vehicles to prevent their drivers from being dazzled.

The driver can therefore leave the high-beam headlamps on at all times and use their full range without bothering or endangering other road users.

This function is active at speeds above 30 km/h when travelling in the dark on roads without street lighting.

Mercedes-AMG SL, R 231, 2015

Infotainment: “Always on” and sophisticated sound systems

Let the music play

Thanks to Mercedes me connect, the new SL is intelligently networked. The atmosphere is like that of a concert hall, even when the roof is open, thanks to the Frontbass system, which had its world premiere in the SL in 2012.

The new SL is intelligently networked and “always on”. This is ensured thanks to the standard-fit communications module (on-board SIM card) which enables the use of Mercedes me connect services.

The available Standard Services currently include Accident Recovery, Breakdown Management and Maintenance Management, as well as Telediagnostics, for example.

15C1369_13

Also available as standard is the Mercedes-Benz emergency call system. In an accident this service automatically connects the occupants with the Mercedes-Benz Emergency Call Centre and sends the position and status of the vehicle to the rescue operations centre.

A rescue vehicle can then be dispatched immediately. The system works automatically, but can also be triggered manually.

15C1369_12

The optional Remote Online feature provides the technical basis for the SL to use Remote Services. For example, navigation destinations can be sent to the vehicle from a computer or smartphone.

Geofencing, Vehicle Tracker and Parked Vehicle Locator, Remote Door Locking and Unlocking or Remote Retrieval of Vehicle Status – these are additional Remote Services and Tracking Services that can currently be activated separately from Daimler AG for three years on the basis of this technical preparation.

With the Smartphone Integration package, compatible smartphones can be integrated into the vehicle via Apple® CarPlay® and used via voice-operated control for example.

In addition, the other vehicle controls can also be used for this. Safe and comfortable use on the road is always ensured.

In the case of Apple® CarPlay® for example, the system supports making and receiving calls, navigation and listening to music, receiving and sending text messages and emails as well as Siri ® voice control.

The selected apps from third-party providers that are also supported include Stitcher Radio® and Spotify®.

The functionality of COMAND Online (optional extra on the SL 400) now includes Live Traffic Information, for example.

Mercedes-AMG SL, R 231, 2015

The latter service uses real-time traffic data for dynamic route guidance with more accurate arrival times. Internet radio is standard for all SL models.

The atmosphere is like that of a concert hall, even when the roof is open, thanks to the Frontbass system, which had its world premiere in the SL in 2012.

It takes up less installation space in the doors by making use of the aluminium cavities in front of the footwell as resonating chambers for the bass speakers.

The optional Harman Kardon® Logic 7® surround sound system has a 10-channel DSP amplifier with a total output of 600 watts and 11 high-performance speakers including Frontbass.

An even more sophisticated sound is produced by the Bang & Olufsen BeoSound AMG sound system. It uses a 16-channel DSP amplifier with a total output of  900 watts in conjunction with 12 high-performance speakers including Frontbass.

Its twin-lens tweeters provide a futuristic show effect with LED light strips – adapted to instrument lighting. The B&O-specific COMAND Menu True Image™ enables individual special settings to be made.

History: a dream sports car for more than 60 years

The SL legend

The exceptional position occupied by the SL in the history of Mercedes-Benz is also evident from its very name: due to its iconic status, the SL has retained its tradition-rich model designation even after the introduction of the new nomenclature.

For more than 60 years now, the Mercedes-Benz model range with the “SL” acronym has enthralled sports car fans around the world.

This legend has its roots in the world of motorsport: in 1952 the 300 SL racing sports car (W 194), with its successes in international competitions, became the spark for the development of two exciting series-production sports cars in the guise of the gullwing coupé and roadster.

Mercedes-AMG SL, R 231, 2015

Their birth ultimately took place in New York: it was there, at the International Motor Sports Show in February 1954, that Mercedes-Benz presented not one but two now legendary SL models: the 300 SL gullwing Coupé (W 198 I) and the open-top 190 SL (W 121).

Based on the legendary “gullwing”, the open-top 300 SL Roadster (W 198 II) appeared on the market in 1957, and was built up to 1963 in parallel with the 190 SL model.

In 1963 the SL series W 113 appeared, referred to as the “Pagoda SL” on account of the characteristic shape of its hardtop roof.

Mercedes-AMG SL, R 231, 2015

This was followed in 1971 by the R 107 series which – also due to the long production period of 18 years – achieved the highest production volume of all SL series to date.

In March 1989 Mercedes‑Benz presented the R 129 series, which was characterised by numerous technical innovations such as the sensor-controlled roll-over bar and the integral seat.

It opened up a new dimension of performance for the SL and was replaced in 2001, after a production period of twelve years, by the R 230 series.

The SL now sported a steel folding top and with its pronounced sportiness harked back to the unique tradition of its legendary forefather.

The current generation of the SL ultimately appeared in the spring of 2012 in the guise of the R 231 series, which combines the high performance level of its predecessor with maximum levels of comfort and efficiency.

The new Mercedes-AMG SL 63 and SL 65

High-performance roadsters now even more attractive

Mercedes-AMG is further enhancing its SL 63 and SL 65 high-performance roadsters with updated technology and expressive design.

15C1369_10

The front section features a completely new design, with a radiator grille which broadens out towards the bottom and the A-wing front spoiler.

15C1369_09

The stylish light signature and the highly comprehensive scope of standard equipment and appointments underscore the high-quality impression.

15C1369_08

The engines set the benchmark in the high-performance roadster segment: the 5.5-litre V8 biturbo engine on board the SL 63 generates an output of 430 kW (585 hp) and peak torque of 900 Newton metres.

Mercedes-AMG SL, R 231, 2015

The SL 65 is powered by a 6.0-litre V12 biturbo engine rated at 463 kW (630 hp) and delivering 1000 Newton metres of peak torque.

Mercedes-AMG SL, R 231, 2015

Outstanding performance, impressive driving characteristics and the expressive, stylishly honed design are the hallmarks of the new Mercedes-AMG SL 63 and Mercedes-AMG SL 65.

Mercedes-AMG SL, R 231, 2015

The technical highlights include the sports suspension based on Active Body Control, the rear-axle differential lock which now features as standard, the even more responsive AMG SPEEDSHIFT MCT 7-speed sports transmission (SL 63) and the five AMG DYNAMIC SELECT driving programmes.

Mercedes-AMG SL, R 231, 2015

“Our updated SL 63 and SL 65 high-performance roadsters offer a unique driving experience, combining hallmark AMG “Driving Performance” with the pleasures of open-air motoring and superior comfort on long journeys, notes Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH.

Mercedes-AMG SL, R 231, 2015

The SL 63 and SL 65 celebrated their world premiere at the Los Angeles Auto Show on 18 November 2015; the market launch will begin in April 2016.

Mercedes-AMG SL, R 231, 2015
Both roadsters offer more power and torque than their respective competitors in this segment. These engines result in high-calibre performance, as illustrated by figures for acceleration from 0 to 100 km/h in 4.1 and 4.0 seconds respectively, for example.

Mercedes-AMG SL, R 231, 2015

The top speed is 250 km/h (electronically limited). The AMG Driver’s package includes an increase in the top speed to 300 km/h (electronically limited).

Mercedes-AMG SL, R 231, 2015

NEDC combined fuel consumption stands at 9.8 litres per 100 kilometres for the eight-cylinder engine and 11.9 l/100 km for the twelve-cylinder variant.

Mercedes-AMG SL, R 231, 2015

The powerhouses incorporate numerous high-tech components for high power output combined with low fuel consumption: in addition to spray-guided direct petrol injection, further features include an all-aluminium crankcase, twin turbocharging, four valves per cylinder with camshaft adjustment and an air/water intercooler.

Mercedes-Benz SL, R 231, 2015

The weight-optimised exhaust system provides for a striking engine sound with an individual character. Large radiators in the front and special vents in the bonnet ensure the required heat balance for the engines.

Mercedes-AMG SL, R 231, 2015

Performance is also boosted by the sports suspension based on Active Body Control, the high-performance composite brake system and the redeveloped AMG SPEEDSHIFT MCT 7-speed sports transmission (SL 63) or AMG SPEEDSHIFT PLUS 7G-TRONIC (SL 65).

Mercedes-AMG SL, R 231, 2015

The intelligent lightweight design is also a major contributory factor to the high driving dynamics. On the SL models the light all-aluminium bodyshell provides the basis for high rigidity, safety and comfort combined with the lowest possible weight.

Mercedes-AMG SL, R 231, 2015

The designers have used the even lighter material magnesium for the panel behind the tank. The boot lid contributes to a further reduction in weight.

Mercedes-AMG SL, R 231, 2015

The interior support consists of a light carbon-fibre composite material. The extremely rigid carbon-fibre component benefits from AMG’s motorsport expertise and is bonded to the equally very light plastic outer shell. This results in weight savings of five kilograms in comparison to a conventional boot lid.

Mercedes-Benz SL, R 231, 2015

Sports suspension based on Active Body Control

The steering knuckles and spring links of the 4-link front axle and almost all the wheel control parts of the multi-link rear suspension are also produced in weight-optimised aluminium.

The reduction in unsprung masses benefits not only agility, but also the response of the spring-damper elements.

Mercedes-AMG remains faithful to the Active Body Control (ABC) active spring and damper system. For even greater agility and high cornering speeds, the AMG SL models have more negative camber all round and fully revised, substantially stiffer elastokinematics.

Mercedes-Benz SL, R 231, 2015

At the touch of a button, the optional Performance suspension (available for SL 63 only) offers an emphatically sporty characteristic with reduced roll angles and taut body damping at the touch of a button (“Sport”) or a more comfort-oriented set-up for a high level of comfort on longer journeys (“Comfort”).

In conjunction with the new electromechanical speed-sensitive power steering, the ­AMG roadsters offer agile cornering and clear feedback to the driver when the car is approaching its critical limits.

The steering features a constant and more direct ratio and variable power assistance which adapts according to the selected suspension set-up.

The standard scope of equipment also includes 3-stage ESP® with “SPORT Handling” mode for particularly ambitious drivers.

Mercedes-Benz SL. 9G-TRONIC Getriebe Mercedes-Benz SL. 9G-TRONIC gear

Even more responsive: AMG SPEEDSHIFT MCT 7-speed sports transmission

The AMG SPEEDSHIFT MCT 7-speed sports transmission on the SL 63 boasts tailor-made dynamics and high variability.

Whether automatic or initiated by the driver using the steering wheel shift paddles, upshifts and downshifts are executed noticeably faster than on the previous model.

Especially in “Sport Plus” and in manual mode, the transmission response is now even more prompt. This enhanced spontaneity was made possible by optimising the engine and transmission software.

Furthermore, the new aluminium shift paddles are now able to transmit the driver’s commands to change gears even faster. The tangible driving dynamics are thus enhanced further.

Mercedes-Benz SL, R 231, 2015

Optimum traction: rear-axle differential lock as standard

For improved traction and driving dynamics, SL 63 and SL 65 are equipped with a mechanical rear-axle differential lock as standard.

This reduces the slip on the inside wheel when cornering, without any control intervention in the braking system. This allows the driver to accelerate out of corners earlier thanks to the improved traction.

The car remains more stable when braking from high speeds, and the limited-slip differential also improves traction when accelerating fast from a standing start.

Mercedes-Benz SL, R 231, 2015

AMG DYNAMIC SELECT driving modes

The five different driving programmes “Comfort”, “Sport”, “Sport Plus”, “Individual” and “RACE” provide the driver with broad scope for influencing the characteristics of the SL 63 and SL 65.

Numerous parameters can be modified, from throttle response to engine sound, enabling the utmost in individualisation.

In the “Comfort” programme the driver experiences a gentle transmission characteristic with comfortable and early gear changes.

Mercedes-Benz SL, R 231, 2015

In “C” mode the car always starts in second gear. In the other driving modes the engine and transmission demonstrate substantially greater agility, in addition to which gear changes are faster.

On the SL 63, an automatic double-declutching function when downshifting and the RACE START function also form part of the standard scope of the AMG SPEEDSHIFT MCT 7-speed sports transmission.

Mercedes-AMG SL, R 231, 2015

Expressive and distinctive: the exterior design

The striking design emphasizes the two high-performance roadsters’ self-assured character. The front section is totally new and markedly more expressive.

It is characterised by the newly designed twin-blade radiator grille, which is now wider at the bottom. The A-wing front apron, the large cooling air intakes with flics as an additional means of guiding air flows and the front splitter emphasize the vehicle’s width.

 

The newly designed bonnet combines design and function in the guise of classic powerdomes and the vents which are required for technical reasons.

The apron in a new diffusor look immediately catches the eye at the rear. All-red tail lights underscore the stylish character.

Mercedes-AMG SL, R 231, 2015

The side skirts also feature a new design and incorporate different inserts according to the model concerned – in silver chrome on the SL 63, while the SL 65 is set apart by applications in high-gloss chrome.

The Night package is optionally available for the first time. The Carbon-Fibre package has been extended to include inserts in the rear apron and in the side skirts.

The SL 63 leaves the factory with 10-spoke light-alloy wheels, painted in titanium grey and with a high-sheen finish, in size 9 J x 19 with 255/35 R 19 tyres at the front and in size 10 J x 19 with 285/30 R 19 tyres at the rear.

The SL 65 is fitted as standard with multi-spoke ceramic polished forged wheels. The front wheels come in size 9 J x 19 and are fitted with 255/35 R 19 tyres, while the rear wheels in size 10 J x 20 are fitted with 285/30 R 20 tyres.

Mercedes-Benz SL, R 231, 2015

Class materials, comprehensive scope of standard appointments: the interior 

The lavishly appointed interior covers every wish: the standard scope includes sports seats in nappa leather with optimised lateral support and model-specific upholstery layout, multicontour function and seat heating.

15C1369_17

The driver has a good grip on the AMG SL at all times with the 3-spoke Performance steering wheel in black nappa leather featuring a flattened bottom rim and silver-coloured aluminium shift paddles.

Carbon-fibre trim and the analogue clock in IWC design highlight the high-performance roadster’s special standing.

15C1369_15

Optional carbon-grain aluminium trim lends the open-top two-seaters an even more personal touch.
