2011 Frankfurt Motor Show: 2012 Mercedes-Benz B-Class makes its appearance

Article by Christian Andrei, on September 13, 2011

Mercedes-Benz has finally unveiled the new B-Class model at the 2011 Frankfurt Motor Show. The new model comes with a new four-cylinder petrol engine that features direct injection and turbocharging. It may also come with a new diesel engine, a new dual clutch transmission, a new manual transmission and new assistance systems. The modifications cover both the interior and exterior, making the new sports tourer appear like a totally reinvented vehicle.

When it comes to performance, its new four-cylinder petrol engines are initially offered with a displacement of 1.6 litres, including the B 180 that has an output of 122 hp/200Nm and the B 200 with 156 hp/250 Nm.

When it comes to the new four-cylinder diesel engines, buyers can choose between the B 180 CDI with 109 hp/250Nm or the B 200 CDI that offer 136 hp/300 Nm. Mercedes-Benz is also debuting the new 7G-DCT dual clutch transmission in the B-Class.

Meanwhile, the new 6-speed manual transmission is designed along similarly compact lines as a three-shaft transmission has a close relation to the DCT.

In addition, the chassis and suspension have been refined while the steering got redesigned. The new B-Class comes with a reduced height (1,557 mm) and an excellent drag coefficient (cd = 0.26).

Four equipment packages are available. These are: Chrome, Sports, Exclusive and Night. Mercedes-Benz enhanced its safety. The B-Class is equipped with a radar-based collision warning system with adaptive Brake Assist as standard, reducing the risk of rear-end collisions.

This is the first compact vehicle in the world to get the system. The new B-Class now also gets the PRE-SAFE preventive occupant protection system, the first vehicle in its category to get one.

The Mercedes B-Class is a model which inspires confidence in its buyers and respect from its competition. The new sports tourer continues to break new ground not only as a Mercedes but as a hatchback saloon car.

The exterior lines emphasize a width you would come to expect from a sports car and the wide grille adds to this effect alongside framed headlamps, a large tailgate, a rear window which replaces the smaller model and new two-part tail lights.

The aerodynamics has been improved and this can be seen in the seamless flow that originates from the bonnet right through to the A-pillar, along the roof and onto the spoiler. This effect serves to elongate the vehicle and makes it appear even sleeker.

The wheel arches have seen a large improvement making them more pronounced and sportier whilst the bottom has been given an update with some dynamic looking side skirts.

Mercedes goes even further in proving the car’s exquisite credentials with the headlamps’ new spotlight elements which are available in the saloon and compact model.

Outstanding aerodynamics is improved even further with an astounding cd value despite station wagon rear end

Mercedes remains lightyears ahead of the competition with an astonishing drag coefficient of cd of just 0.26. In order to bring this into being, Mercedes has modified and optimised this model like never before in order to deliver an excellent display of aerodynamic ingenuity. Improvements have included the flow of air around the front wheels, changes to the underbody and the all-important flow of air.

The new serrated wheel arch spoiler is truly innovative and likely to be a world leader in terms of its properties. The saloon also comes with the option to upgrade to the ECO Technology package in time when it becomes available. What makes the saloon so appealing is that it has almost the same aerodynamic credentials of the E-Class Coupe and comes in with a drag coefficient of cd = 0.24, which for a station wagon is nothing short of staggering.

New concept: lower overall height but more space inside

It is clear Mercedes has high hopes for its B-Class and it has continued this dream with a feat of engineering just short of remarkable. By reducing the height by 1557 mm, the new model is almost 5cm lower than the previous model and yet once inside the vehicle, it is clear that its seat height too has been trimmed by 86 mm to allow for an easier egress without compromising visibility.
