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, the B-Class is a front wheel drive vehicle.
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.
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".
These are two innovations, patented by Mercedes-Benz as:
As a secondary benefit, because the seats have been raised by 20 cm, the passengers are taken away from the more common area of lateral impact in accidents.
The multifunction steering wheel (standard feature) allows the driver to use his/her thumbs to control the radio, telephone and other systems. There are 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.
W169 defines the Light & Sight package with several benefits:
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 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 contrary, the Tensioners (standard feature) continuously adjust to remove any possible slack, and increase the tightness if necessary. The driver has a report if all the belts are buckled (standard feature).
Lastly, the active head restraints (standard feature) respond actively to a collision, assuring even more protection.
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:
All the engines meet the Euro IV emissions regulation, and a particulate filter system is available as an option for the diesel units (this reduces about 99% of the particle emissions, without the need for additives).
As an option there is an Autotronic Continuously Variable Transmission (CVT) in which the ratios are changed continuously by means of a pulley-wheel variator and a steel thrust belt. This allows the car to accelerate with no interruption of tractive power and attains the maximum output more quickly. This is adjustable according to driving style: economical or sporty.
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).
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 .
The new B-Class is now available with new upholsteries and trims.
