Mercedes W245 B-Class 2005 – 2010
The Mercedes-Benz B-Class (codename W245) is a compact MPV introduced by German automaker Mercedes-Benz in March 2005.

It is essentially an enlarged A-Class keeping the same engine and suspension system. Like the A-Class, and unlike any other vehicle Mercedes builds or has built, the B-Class is a front wheel drive vehicle.
Mercedes-Benz describes this vehicle as a Compact Sports Tourer instead of hatchback or multi-purpose vehicle, like its R-Class model, which is called a Grand Sports Tourer.
It was released in Europe in the late spring of 2005 and in Canada in the autumn of 2005. Plans to import the car to the US through Mexico were put on hold due to a strong euro, but it is likely that a new version of the car will come to the US in 2011.
Keeping in mind its United States’ market in comparison with the A-Class and indeed emulating the R-Class, the aspect of the B-Class was stylized from the back to the nose. Some of the tiny stylistic details of the Baby-Benz (popular name of the A-Class) were removed. In particular, the front of the vehicle was lengthened (although maintaining the Sandwich anti-crash system).
Sandwich floor concept
The B-Class W245 maintains the sandwich floor concept.
The powertrain (engine and transmission) moves beneath the passenger cell (located at high seating position) in the event of a big frontal impact. According to a study : “the front section of the A-Class would have to be considerably longer in order to offer the same impressive level of occupant safety in the event of a heavy frontal impact”.
Pre-facelift B-Class 170
The B-Class presents a wide interior, basically due to the Sandwich floor.
The multifunction steering wheel (standard feature) allows the driver to use his/her thumbs to control the radio, telephone and other systems. The power assisted steering (standard feature) aids in the control of the automobile, varying according to the speed.
The COMAND APS is a system where Route instructions are given to the navigation system, and the information is provided via SMS. The car radio, DVD and telephone controls are combined into a single unit with a 6.5 inch screen. The options are: standard Audio 20 radio/single CD, Audio 50 APS or COMAND APS.
Parktronic emits warning tones and uses multiple LEDs to indicate how far the car is from an obstacle.
W245 defines the Light & Sight package with several benefits:
- Bi-xenon HID headlamps (optional feature) with gas-discharge bulbs for the dipped beam
- Cornering lights (standard feature) where the main-beam dips at road junctions and tight corners
- Active light system (standard feature) where the beams follows the steering movements
- Headlamp Assist (standard feature) is a sensor on the windscreen monitoring ambient light levels to automatically switch on the headlamps as required
- Rain sensor (standard feature) smoothly adjusts the wiper speed, depending on the intensity of the rainfall.
- As a standard addition, when entering a tunnel or an underground garage, the Tunnel Mode closes all windows and the panoramic sliding sunroof.
The multicontour seat (optional feature) is composed of a set of small air cushions individually adjusted to the driver’s body, as he/she wishes.
The W245 units have a powerful car air conditioning system, with separate temperature adjustment for driver and front passenger.
Standard CDI models include a Heater Booster System (standard on CDI models) that instantly floods the interior of the B-Class with hot air. The most advanced system is the Thermotronic (optional feature) that maintains and regulates the temperature in accordance with a sophisticated set of sensors which measure temperature, sunlight, humidity and even pollutant levels in the ambient air, causing all openings to close automatically.
The new optional sunroof is divided in small panels that can be displaced individually. Each one can be controlled separately to selectively administer the shades inside the W245.
High-strength and ultra-high-strength steel alloys are combined with high-strength bonded joints.
The B-Class has several airbags. The front airbag is adaptive with two-stage gas generators (standard feature), where the system evaluates the severity of the accident. The B-Class also includes side airbags for head and thorax (standard for driver and front passenger).
Two other additions are optional: Rear Sidebags (optional feature) for side-on collisions in the back seats and Windowbags: large airbags expanding like a curtain from A- to C-pillars in side-on collisions.
The belt system of the B-Class W245 is simply surprising. The Adaptive Function (standard feature for driver and front passenger) adapts the force exerted by the belt, relaxing dynamically during the collision. On the other hand, the Tensioners (standard feature) continuously adjust to remove any possible slack, and increase the tightness if necessary. The driver is notified if all the belts are buckled (standard feature).
Head and neck
Lastly, the active head restraints (standard feature) respond actively to a collision, assuring even more protection.
Other standard features
While driving there is the Acceleration-Skid Control (ASR) (standard feature) and Electronic Stability Program ESP (standard feature) that reduce the risk of skidding. There are disc brakes on all four wheels, and emergency stops are improved with the Anti-lock braking system (ABS) and Brake Assist System (BAS), standard on the Mercedes Benz A-Class. BAS detects emergency braking (most drivers apply the brakes quickly but without enough pressure) and exerts maximum brake pressure.
To make more room for transporting goods, it is possible to fold the seats forward and then level them at two different heights. They provide different final modular space combinations.
Its implementation is provided by two systems:
Easy-Vario: Both rear-seat cushion sections are folded forward, while the luggage compartment floor can be set to one of two different heights. (Optional feature)
Easy-Vario-Plus: Both rear-seat cushion and the front passenger seat are folded forward. This increases the load capacity to as much as 1995 litres. (Optional feature)
The B160 and B180 conform to Euro V emission standards. The rest of the engines conform to Euro IV emission standards. A particulate filter is available as an option for the diesel units (this reduces about 99% of the particle emissions, without the need for additives).

The B-Class is a front-wheel drive car.
In the W245 the dynamic handling was powered in precision tracking and anti-roll support, with the Parabolic Rear Axle (standard feature) that grants a pivotal role in the driving. The car has a Selective Damping System (standard feature), where the shock absorber forces are administered differentially, in example under normal conditions (soft absorption) and while cornering at speed (full damping force).
The W245 presents light alloy wheels. With the run-flat feature (continuous mobility or zero-pressure tyres can be driven at normal speeds). There is Tirefit tyre sealant and a tire-pressure-loss warning device by ESP technology (standard feature).
2008 B-Class facelift
2008 Mercedes-Benz B-Class (North America)
Mercedes-Benz has recently released a refreshed-look B-Class alongside a refreshed-look A-Class and M-Class.
The newer B-Class has a restyled hood, front bumper, rear tail lamps, side exterior mirrors and is now available in the B170 NGT Blue Efficient. The B170 NGT Blue Efficient can run on either gas or petrol, and when full, can cover up to 1,000 kilometres (620 mi).
The new B-Class is now available with new upholsteries and trims.
