Versatility at its best
Stuttgart – After a world premiere at the New York International Auto Show in March this year and the positive feedback received there, Mercedes-Benz is convinced that it is on the right track with the new-generation R-Class. A completely redesigned front section in particular enhances the overall look of this model, with styling cues taken from Mercedes-Benz saloon and SUV models. The interior of the “twenty-ten” model year R-Class complements this fresh exterior, combining as it does the good use of space found in the latest MPV models with the comfort, high-class appeal and prestige of classic Mercedes-Benz luxury-class saloons. At the same time this latest generation retains the interior versatility of its predecessor, whilst also benefiting from the robustness and all-wheel drive capability it draws from the Mercedes-Benz SUVs.
Engine line-up: economical drive systems
In addition to the modern petrol variants adopted from the preceding model, with their customary effortless power delivery and high drive comfort, the appeal of the R-Class is now also enhanced by a range of optimised diesel engines. Dr. Thomas Weber, Member of the Daimler AG Board of Management with responsibility for Group Research and Mercedes-Benz Cars Development: “We have reworked the R-Class completely, thereby adding to its appeal and enhancing its premium qualities, but without losing any of the advantages of this unique vehicle concept. On top of this, our BlueEFFICIENCY strategy makes the R-Class the most economical and environmentally friendly MPV in the premium segment“.
Despite delivering the same output and improved performance compared with the preceding model, the new R 300 CDI BlueEFFICIENCY consumes around 7 percent less fuel, at 7.6 l per 100 km*. The new R 350 CDI 4MATIC combines the high performance of a V8 model with the low fuel consumption of an economical V6 variant. It is happy with just 8.5 litres of diesel* per one hundred kilometres, thereby undercutting its predecessor by 0.8 litres – yet is able to offer significantly enhanced performance. While previously the maximum performance topped out at 165 kW (224 hp), the V6 diesel engine now boasts 195 kW (265 hp) as well as 620 Newton metres of torque. Making its debut here in the R-Class, it is a powerful package that enables this most dynamic of all the diesel-powered R-Class models to achieve effortlessly superior levels of performance. Acceleration from 0 to 100 km/h takes 7.6 seconds, while the top speed is 235 km/h.
With the R 350 BlueTEC 4MATIC, Mercedes-Benz is offering one of the cleanest diesel models in the world. The V6 engine achieves an output of 155 kW (211 hp) and torque of 540 Newton metres. Compared with its predecessor, this model also manages to achieve reduced fuel consumption and lower emissions while providing enhanced performance. Thanks to AdBlue© exhaust after-treatment, the compression-ignition engine consumes an average of 0.3 of a litre less, at 8.4 litres of diesel* per one hundred kilometres, generating in the process the same level of emissions as a comparable petrol engine. As a result, this model currently already meets the emission values planned for 2014 according to the EU6 standard. All other petrol and diesel versions of the R-Class meet the EU5 standard.

Geared up: 7G-TRONIC as standard in all models
All R-Class models are equipped with the latest-generation of the innovative
7G-TRONIC automatic transmission. This seven-speed transmission now has new bearings and couplings, operates with different oil pressures and uses a new, low-friction oil. These measures reduce friction and churning losses, thereby improving efficiency. The new torque converter with slip-reduced lockup clutch likewise improves efficiency and aids fuel economy. In addition, standstill decoupling lowers fuel consumption. This technical feature reduces transmission input torque in “D” when the car is at rest, for example at traffic lights. This lowers the stress on the engine, making for lower fuel consumption, better vehicle acoustics and smoother idling. The slip-controlled clutch is engaged as soon as the driver releases the operating brake, ensuring no delay when the vehicle moves off.
Simply stunning: the design of the R-Class
The latest generation of the R-Class features a new, self-assured appearance. The overall impression is determined by an integrity of design that encapsulates the unique personality of this highly versatile vehicle. The focus of the designers was the completely revised front section which, by emphasising the width and making use of a horizontally structured bonnet, affords the entire vehicle a look which is as harmonious as it is powerfully dynamic. As well as the bonnet, the vehicle’s wings, radiator grille and surround, headlamps and bumpers with chrome underguard have all been completely redesigned. As an optional extra, a chrome insert with integrated LED daytime driving lights in conjunction with bi-xenon headlamps is available to enhance the look of the R-Class even further.
The side view features coupé-like lines – a pleasant contrast to conventional MPVs – and is characterised by the modified exterior mirror housings and the wheel design. Wheels are available in 5-spoke, 5-twin spoke or 10-spoke designs, and in sizes ranging from 43.2 to 53.3 centimetres (17 to 21 inches). The design idiom of the front is continued consistently through to the rear section which, with its new bumper covering, modified tail lamps and integrated tailpipe trim, has also been given an accentuated wide look. The 2010 model year R-Class looks particularly attractive in the new “diamond white” paint finish.
Wellness program: a relaxed environment for both longer journeys and everyday use
Particularly where seating variations are concerned, the interior of the new
R-Class offers a great deal of scope: in its standard version this saloon designed for relaxed, safe touring has five seats, but four, six or seven-seater configurations are also possible. The front seats are partially electrically adjustable as standard, and on request the front occupants can also enjoy actively ventilated, heated multicontour seats with fully electric adjustments and a memory function. The R-Class also reveals another benefit in the form of its large, versatile luggage compartment: in the standard-wheelbase versions the luggage compartment holds up to 1950 litres, while the long-wheelbase version boasts 2385 litres.
In all five-seat variants there is a separate stowage compartment beneath the load compartment floor, while the optional EASY PACK tailgate, which can be operated remotely by means of a switch or key, also makes access to the luggage compartment easier. As such the R-Class is the most variable and spacious vehicle in the entire Mercedes-Benz passenger car product range.
The bright, classic interior – which seems even more spacious when fitted with the optional panoramic glass sunroof – makes use of new materials and colour combinations to enhance the high-class appeal and quality of this luxury tourer. At the same time they underline the sense of wellbeing inside the vehicle which is so typical of a Mercedes-Benz. Available interior appointments include the upholstery combination of “Aspen” fabric and breathable, soft-touch ARTICO man-made leather.
Two-tone interior appointments are a new addition to the range: this is where the base colour almond beige can be combined with the contrasting shade of mocha brown. Alternatively, the base colour alpaca grey combined with contrasting dark basalt grey is also available. Both colour combinations are used on the dashboard, steering wheel, centre console, seats, door linings and floor coverings. When choosing ARTICO or leather appointments at the same time, the piping is finished in a contrasting colour. The AMG Interior Sports package includes single-tone black nappa leather appointments as standard. As alternatives to the aluminium trim with a dark longitudinal grain or the chrome trim in silver shadow, it is also possible to order luxurious wood trims in high-gloss brown eucalyptus, high-gloss brown burred walnut or high-gloss anthracite poplar.
Model range: the R-Class with a personal touch
The nine basic variants already provide plenty of opportunity to select an R‑Class to suit specific individual requirements. All models boast numerous features as standard which help to make travelling both on long journeys as well as on short urban trips even safer and more relaxed. These features include the unique anticipatory occupant protection system PRE-SAFE®, a complete restraint system with eight airbags, crash-active NECK-PRO head restraints, a tyre pressure loss warning system and adaptive brake lights. Safety is also enhanced thanks to high-performance telematic systems such as the Audio 20, Audio 50 APS or COMAND APS with an extremely user-friendly interface.
The THERMATIC automatic climate control system is fitted with a combination filter to further reduce pollutants which may be contained in the outside air entering the vehicle. As an optional extra, a THERMOTRONIC system providing separate rear air conditioning is available to meet all interior air conditioning requirements. The spacious glove compartment now comes with an AUX-IN connection for external audio or entertainment devices. Connection options can also be extended further with an optional Media Interface (UCI).
To complement the extensive standard equipment, the R-Class provides a variety of assistant systems which push ride comfort and safety to the highest level and underpin the vehicle’s leading position in this market segment. These include DISTRONIC proximity control, AIRMATIC air suspension with the Adaptive Damping System (ADS), or Blind Spot Assist, which can make changing lanes significantly safer. The modern LINGUATRONIC voice control system makes using the telematics systems even easier and more convenient, while a reversing camera provides for smooth, easy parking or manoeuvring in blind spots. As soon as the driver engages “R” gear, the image from the camera is shown on the high-resolution COMAND APS display. Rear passengers, meanwhile, can enjoy their own entertainment programme thanks to the rear seat entertainment system. Seat heating can also be ordered for the second row of seats to increase comfort even further in winter.
Valuation: surveys confirm high resale expectations
Experience shows that Mercedes-Benz models are among the most stable on the market in terms of value retention, and they therefore offer a significant financial advantage. This was confirmed once again last year by a neutral third-party when the German specialist magazine “Auto Bild” selected the “2010 Value Champions” in different vehicle categories based on surveys conducted by Saarbrücken-based market research institute Bähr & Fess Forecast. The “Value Champion” among MPVs, the R 300 CDI, emerged at the head of the field in this market segment, and according to the forecasts would retain a value of 47.5 percent after four years. The R‑Class already held this leading position in an expert analysis of residual values last year.

Diverse, comfortable and fully equipped
The new R-Class enhances the merits of this vehicle category even further. In addition to the fresh exterior, the R-Class also impresses with a number of interior features in particular. These include the good use of space found in the latest MPVs and the comfort, high-class appeal and prestige of the S‑Class. At the same time, this latest generation offers the interior versatility for which its predecessor was renowned, while also boasting the robustness and all-wheel-drive properties of Mercedes-Benz SUVs.
With a total of 9 base versions, the R-Class provides the most comprehensive model range in the premium segment of luxury tourers. Together with the significantly more appealing body design, the complete range of standard equipment and the numerous individualisation options, the R-Class can be tailored specifically to meet individual requirements. If there was such a thing as a vehicle versatility test, then the R-Class would certainly be the favourite to take first place.

Simply stunning: the design of the R-Class
Impressive appearance with new highlights
The latest-generation R-Class shows a new self-confidence. Its entire appearance is noticeably more attractive, underlining the unique character of this multi-talented vehicle. The focus of the designers was on the completely restyled front section, with an emphasis on width and a horizontally structured bonnet to make the vehicle appear more harmonious, muscular and dynamic.
Expressive: the new front section is full of character
At the front end of the R-Class, the bonnet, wings, radiator grille, headlamps and bumper have been completely redesigned. On request, in conjunction with bi-xenon headlamps, a chrome insert enhances the integrated LED daytime driving lights. The character of the R-Class can also be underlined by an optional, strikingly contoured, chrome-look underguard.
The new bonnet has more marked contours, and is more arrow-shaped at the front edge. The wider, higher radiator grille is more steeply angled, while the bumper cladding is more striking, with clear-cut lines. The side recesses in the bumper, where the fog lamps and daytime driving lights are located, are spaced well apart and give the front section an impression of width. The lines of the side skirts are harmoniously continued forward in the updated wings and grille.
The new, dynamic “face” of the R-Class is particularly impressive. The newly designed headlamps blend perfectly into the front end, emphasising the horizontal lines. The “eyelids” continue the beltline along the flanks, and are arranged above the chromed headlamp tubes to produce an assertive, concentrated gaze.
Perfect proportions
Dynamism is also the order of the day where the side aspect is concerned. With the coupé-like lines of the window area, the luxury tourer distinguishes itself attractively from conventional MPVs. Eye-catching details of the clearly contoured flanks include the larger exterior mirror housings, which are set well away from the doors and are held by slim stems. The strikingly designed mirror housings in the vehicle colour have integrated indicator repeaters in the form of a stylised arrow.
The new wheel designs are equally eye-catching: the range includes light-alloy wheels in 5-spoke, 5-twin-spoke or 10-spoke designs in sizes from 43.2 to
53.3 centimetres (17 to 21 inches).
Perfect finish: the rear section of the R-Class
The rear section harmoniously continues the design idiom of the front, with a new bumper cladding, modified tail lights, a diffuser and integrated tailpipe trim emphasising the width with more horizontal structures, as at the front. The bumper also picks up the line of the side skirts, giving the effect of a continuous line running around the entire bodywork. Tail lights with LED and fibre optic technology, new exterior contours and horizontally arranged lighting functions lend the finishing touches to the rear section.
The 2010 model year R-Class looks particularly attractive in the new “diamond white” paint finish.
Please take a seat: interior appointments
Sitting comfortably in spacious luxury
If there were a versatility test for automobile interiors, the R-Class would undoubtedly be a candidate for the top score. A wide variety of options are available when it comes to seat variations in particular: designed for a relaxed, safe driving environment, the saloon offers five seats as standard in both the normal and long-wheelbase versions, but four, six or even seven-seat configurations are also possible.
Seating arrangement: from 2-2-0 or 2-3-0 and 2-2-2 right up to a 2-3-2 system
The space provided behind the front seats is so generous that up to three child safety seats can be installed at the same time. If only four seats are required, the centre backrest can be folded down to serve as an armrest. Alternatively, the six-seater version features a console as standard in place of the centre seat. This also enables the R-Class to shine with four luxurious individual seats.
R-Class customers who particularly like variety are able to produce other formations by opting for two individual seats in the rear. With three passengers seated in the middle row, this gives a total seating capacity of seven. Groups of up to six people choose the popular 2-2-2 seating system, which provides all the occupants with an individual seat. The R-Class comes with partially power-adjustable seats for driver and front passenger as standard, while as an option front passengers can also enjoy the luxury of actively ventilated and heated multicontour seats with full power adjustment and memory function.
The R-Class also reveals another benefit in the form of its large, versatile luggage compartment: this has a capacity of up to 1950 litres, while the long-wheelbase version boasts 2385 litres. In all five-seat variants there is a separate stowage compartment beneath the load compartment floor, while the optional EASY PACK tailgate, which can be operated remotely by means of a switch or key, also makes access to the luggage compartment easier. This makes the R-Class the most variable and spacious vehicle in the entire Mercedes-Benz passenger car product range.
Refined atmosphere for maximum driving pleasure
The high-class interior – which seems even more spacious when fitted with the optional panoramic glass sunroof – makes use of new materials and colour combinations to enhance the high-class appeal and quality of this luxury tourer. At the same time they underline the sense of wellbeing which is so typical of a Mercedes-Benz interior. Available interior appointments include the upholstery combination of “Aspen” fabric and breathable, soft-touch ARTICO man-made leather.
Two-tone interior appointments are a new addition to the range: this is where the base colour almond beige can be combined with the contrasting shade mocha brown. Alternatively, the base colour alpaca grey combined with contrasting dark basalt grey is also available. Both colour combinations are used on the dashboard, steering wheel, centre console, seats, door linings and floor coverings. When choosing ARTICO or leather appointments at the same time – in this case the seats feature a new transverse and linear piping design – the piping is finished in a contrasting colour. As alternatives to the aluminium trim with a dark longitudinal grain or the chrome trim in silver shadow, it is also possible to order luxurious wood trims in high-gloss brown eucalyptus, high-gloss brown burred walnut or high-gloss anthracite poplar.
The cockpit impresses with its newly designed instrument cluster. The dials and needles have a white background, and are even easier to read thanks to a three-dimensional effect.
That’s entertainment – telematics and multimedia in the R-Class
The telematics of the R-Class impress with intuitive and user-friendly operation, high performance and great versatility. The luxury tourer is fitted as standard with the Audio 20 CD system with CD changer. This includes a 12.7 cm (5-inch) colour display, a twin tuner for better radio reception, speed-sensitive volume control, eight loudspeakers and a keypad for entering telephone numbers and radio frequencies. A hands-free system with Bluetooth interface and an Aux-in connection for mobile audio devices such as an iPod are also integrated. On request, a Media Interface (UCI) is also available to connect an external music memory to the onboard electronics and the control system, so that music tracks are shown in the instrument cluster and the colour display in the centre console, and can be conveniently accessed using the keys in the multifunction steering wheel. The battery of the audio device is charged at the same time.
Passengers can also enjoy full, concert-hall surround-sound with the optional, latest-generation Harman Kardon® Logic7® sound system. With a high output, a digital signal processor (DSP) and Dolby Digital 5.1, this ensures an outstandingly clear listening experience. As an optional extra, there is also a rear seat entertainment system with two large 20.3 cm (8‑inch) screens, a DVD player and two wireless headsets for greater freedom of movement, plus a remote control unit.
One particularly impressive optional extra is the COMAND APS system, for which the customer receives free navigation map updates covering 39 European countries for a period of three years after first registration. In addition to the features of Audio 20 CD, this multimedia system has a 6-disc CD changer, a high-resolution 16.5 cm (6.5-inch) colour display, a 4 GB memory for MP3 files (Music Register) and a memory card slot (SD cards). The HDD navigation system with various map displays and automatic traffic tailback reporting (TMC) rapidly guides the driver to the desired destination. COMAND APS also includes a DVD audio/video player and a compass function, which is shown in both the instrument cluster and the central COMAND display. Like the Audio 50 system, COMAND APS features the latest LINGUATRONIC voice-operated control system.
Comprehensive safety concept
Eight airbags, crash-responsive head restraints and an electronic guardian angel
All models have numerous features as standard which help to make long journeys as well as short urban trips even safer and more relaxed. These features include the unique anticipatory occupant protection system PRE-SAFE®, a complete restraint system with eight airbags, crash-responsive NECK-PRO front head restraints, a tyre pressure loss warning system and adaptive brake lights. Safety is also enhanced by high-performance telematic systems such as the Audio 20, Audio 50 APS or COMAND APS with an extremely user-friendly interface, as well as a raised seating position. This gives the driver a good view of the traffic conditions, enabling him or her to recognise potential dangers more quickly and easily.
Everything considered: integral Mercedes-Benz safety concept
The comprehensive Mercedes approach to integral safety also applies in the new R-Class. This trailblazing safety philosophy goes well beyond compliance with standardised crash test regulations. It concerns itself with all aspects of driving – everything that is important for the safety of the vehicle occupants and other road users. The Mercedes safety concept divides these aspects into four phases:
1. Safe driving: avoiding danger, warning and assisting in good time
2. In the event of danger: acting in an anticipatory manner, e.g. with PRE-SAFE®
3. In an accident: provide protection as needed
4. After an accident: avoid even worse consequences and make rapid assistance possible
Comprehensive restraint system for the best possible occupant protection
Combined with the front and rear deformation zones, the high-strength occupant cell forms an effective basis for occupant protection systems that include:
– adaptive, two-stage airbags for the driver and front passenger
– sidebags in the front, and in the middle row of seats as an option
– windowbags across all three rows of seats
– NECK-PRO crash-responsive head restraints for the driver and front passenger (optionally NECK-PRO luxury head restraints)
– 3-point seat belts on all seats
– belt tensioners and belt-force limiters for driver and front seat passenger
– seat belt tensioners and single-stage belt-force limiters in the middle and rear seat rows
– ISOFIX child seat anchorages for up to three child restraint systems in the centre seat row
– belt height adjustment for the driver and front passenger
– belt status display for rear-seat passengers in the instrument cluster
– automatic child seat recognition (optional) with deactivation of the
front passenger airbag if a special Mercedes-Benz child seat is fitted
The electronic guardian angel: PRE-SAFE® has a preventive effect
Occupant protection in the new R-Class begins well before an accident. The Mercedes-Benz invention PRE-SAFE® is able to activate preventive measures reflexively when it recognises the danger of an accident, so that the belts and airbags can protect the occupants to best effect during the collision. This multiple award-winning technology is standard equipment.
PRE-SAFE® uses a synergy of active and passive safety: it is networked with Brake Assist (BAS) and the Electronic Stability Program ESP®, whose sensors can recognise potentially critical handling situations and send corresponding information to the electronic control units within milliseconds. These sensor data are also used for preventive occupant protection by PRE-SAFE®. The PRE-SAFE® protective measures are reversible: if the accident is avoided, the preventive belt tensioning is relaxed automatically, and the passengers can return the seats and sliding sunroof to their original positions. The preventive occupant protection is then immediately ready for use again.
In case the worst happens: Daimler trains the fire services
Like the R-Class, all automobiles from Mercedes-Benz are among the world’s safest. This high protection potential is the result of Daimler AG’s comprehensive approach. Of course, however, protective measures reach their limits if the parameters make control intervention more difficult and – in the case of very serious accidents – if access to and recovery of the occupants is sometimes no longer possible via the vehicle doors.
Even in these extreme circumstances, where the focus is on “patient-compatible recovery”, the company follows its comprehensive safety philosophy and assists the emergency services with their work. This is because the effectiveness of post-accident assistance, where emergency doctors, paramedics and the fire services work together to recover the occupants as rapidly and carefully as possible, depends absolutely on preparation.
To this end, Daimler AG offers the fire services practical training events during which they can learn and apply a wide variety of recovery techniques using the latest models. In addition, Daimler provides detailed recovery guidelines and so-called ‘rescue cards’ online. These are in accordance with the standards set by the VDA workgroup, and show recovery techniques specific to the different model series.
Tradition: 40 years of accident research at Mercedes-Benz
This close cooperation between Daimler safety specialists, the emergency services and the police has a long tradition: in 1969 Mercedes-Benz started its ongoing accident research programme, in which engineers evaluate collisions involving the company’s vehicles in the Stuttgart region soon after they occur – and in special cases even worldwide. Again and again, the findings of the accident researchers provide important information on components that can be specifically improved in terms of passive safety. The investigators have examined around 4000 accidents since their work started 40 years ago. Each crash is documented with an 80-page accident report. This continuously growing database will enable vehicles to be made even safer in the future.
Drive system and chassis
Drive for economy
In addition to the economical petrol variants adopted from the preceding model, with their customary effortless power delivery and high drive comfort, a range of optimised diesel engines enhances the appeal of the R-Class. With a fuel consumption figure of 7.6 l/100 km (combined NEDC consumption), the R 300 CDI BlueEFFICIENCY requires around 7 percent less fuel than its predecessor, the R 300 CDI without BlueEFFICIENCY technology.
R 300 CDI BlueEFFICIENCY: low fuel consumption MPV
As with all BlueEFFICIENCY models from Mercedes-Benz, the R-Class features a whole range of measures to reduce fuel consumption. In addition to the direct-injection diesel engine and the low-friction powertrain, these measures include weight reductions achieved through the use of high-strength and ultra-high-strength steels in the bodyshell and weight-optimised light-alloy wheels. Aerodynamic exterior mirrors and underbody panelling lower drag, while 235/65 R 17 tyres reduce rolling resistance. A controlled fuel pump and energy-saving electrohydraulic power steering also lower the energy requirements. A display indicating the current fuel consumption and a fuel consumption computer enable the R-Class driver to check fuel efficiency at any time, and adapt the style of driving as necessary.
Economising can be fun: the new V6 diesel with 195 kW (265 hp) and 620 Nm
The new R 350 CDI 4MATIC is entering a particularly sporty league, and combines the high performance of a V8 model with the low fuel consumption of an economical V6 variant. It is happy with just 8.5 litres of diesel (combined NEDC consumption) per one hundred kilometres, thereby undercutting its predecessor by 0.8 litres – yet is able to offer significantly enhanced performance. While previously the maximum performance topped out at 165 kW (224 hp), the V6 diesel engine now boasts 195 kW (265 hp) as well as massive torque of 620 Newton metres. This powerful package is celebrating its world premiere in the new R-Class, and enables the sportiest of all diesel-powered R-Class models to achieve effortlessly superior levels of performance. Acceleration from 0 to 100 km/h takes 7.6 seconds, while the top speed is 235 km/h.
This evolutionary stage of the successful V6 diesel engine was realised with improved engine management in the form of new-generation control units and new software, new sensors and actuators, and more efficient after-treatment in the maintenance-free diesel particulate filter system with reduced back-pressure. In addition to more effective cooling of recirculated exhaust gas using a variable bypass valve, the in-engine measures include a reduction of the compression ratio from 17.7:1 to 15.5:1, an optimised VNT turbocharger with low-friction shaft bearings for greater agility and high output, new injection nozzles and revised ducting in the intake tract. A whole package of measures has resulted in substantial fuel savings: these include generally lower in-engine friction, more efficient thermal management, an improved compound oil pump and modified cylinder head cooling.
R 350 BlueTEC 4MATIC: as clean as a petrol model
With the R 350 BlueTEC 4MATIC, Mercedes-Benz is offering one of the cleanest diesel models in the world. The V6 engine achieves an output of 155 kW (211 hp) and substantial torque of 540 Nm. Compared with its predecessor, this model also manages to achieve reduced fuel consumption and lower emissions while providing enhanced performance. Equipped with highly-effective AdBlue© exhaust gas after-treatment, the compression-ignition engine consumes an average of 0.3 of a litre less, at 8.4 litres (combined NEDC consumption) of diesel per one hundred kilometres, generating in the process the same level of emissions as a comparable petrol engine.
As a result, this model currently already meets the emission values planned for 2014 according to the EU6 standard. BlueTEC is a technology developed by Mercedes-Benz for the effective reduction of emissions by diesel vehicles, especially nitrogen oxides. In this process, AdBlue®, a non-toxic, aqueous urea solution is injected into the stream of exhaust gases. This releases ammonia, which breaks down up to 80 percent of the nitrogen oxides into harmless nitrogen and water in the downstream SCR catalytic converter (Selective Catalytic Reduction).
Effortless power delivery with high drive comfort:
The petrol variants in the R-Class
The range of petrol engines has three variants, and gives the R-Class a high level of drive comfort together with effortless power delivery and a moderate fuel consumption. The V6 petrol engine of the rear-wheel drive R 300 develops 170 kW (231 hp), accelerates the R-Class from zero to 100 km/h in 9.6 seconds and provides a top speed of 222 km/h. The combined NEDC fuel consumption is 11.1 l/100 km. The all-wheel drive R 350 4MATIC with a 3.5-litre V6 engine develops 200 kW (272 hp) and a maximum torque of 350 Newton metres. Despite this extra output and performance (top speed 230 km/h, 0-100 km/h in 8.3 seconds), the R 350 4MATIC consumes only 0.5 l/100 km more (combined NEDC fuel consumption) compared with the R 300. This low difference in consumption once again demonstrates the high efficiency of the 4MATIC all-wheel drive system.
In the top-of-the-range R 500 4MATIC, the 5.5-litre V8 engine with 285 kW (388 hp) and a maximum torque of 530 Newton metres guarantees impressive performance figures. A sprint from zero to 100 km/h is absolved in 6.3 seconds, with a top speed of 250 km/h.
Geared up: 7G-TRONIC as standard in all models
All R-Class models are equipped with the latest-generation of the innovative 7G-TRONIC automatic transmission. The Fuel Efficiency variant of the seven-speed transmission has new bearings and couplings. Different oil pressures and a new, low-friction oil help to reduce friction and churning losses. The new torque converter with slip-reduced lockup clutch likewise improves efficiency and aids fuel economy. In addition, standstill decoupling lowers fuel consumption. This technical feature reduces transmission input torque in “D” when the car is at rest, for example at traffic lights. This lowers the stress on the engine, making for lower fuel consumption, better vehicle acoustics, greater comfort at standstill and smoother idling. The slip-controlled clutch is engaged as soon as the driver releases the operating brake, ensuring no delay or quality compromise when the vehicle moves off.
Stability pact: the well-proven suspension of the R-Class
The R-Class has a dynamically active and comfortable suspension with high safety reserves as standard. All model variants have steel springs, and in the 5+2-seater variants and the top R 500 4MATIC model self-levelling rear air suspension is included as standard. This self-levelling rear air suspension is available as an option for all other models. The AIRMATIC package with air suspension, the Adaptive Damping System and level adjustment improves both ride comfort and handling dynamics, and is likewise optionally available for all R-Class models.
