Mercedes-Benz B200 CDI
Design, dynamism and dimensions - these are the outstanding features of the new B-Class, the Mercedes-Benz Compact Sports Tourer.
With this novel Sports Tourer concept, Mercedes-Benz is once again asserting its role as the trendsetter among car brands and preparing the way for a young market segment with a promising future. The Mercedes-Benz B-Class meets the wishes of today's motorists for a car with generous space, exemplary comfort, excellent practicality, an exciting design and a high level of driving pleasure. This new Mercedes development takes the advantages of different vehicle concepts and combines them into an interesting and distinctive profile of its own: as a Compact Sports Tourer, the B-Class is a touring, family and recreational vehicle with incomparable added experience value in terms of design and dynamism.
One of the major advantages of the Compact Sports Tourer is the sandwich concept developed by Mercedes-Benz. Thanks to the space-saving arrangement of the engine and transmission partly in front of and partly beneath the passenger cell, the new B-Class offers the interior spaciousness of larger saloons and estate cars despite its compact external dimensions. The body has a length of 4270 millimetres, corresponding to the compact car class. Inside, however, the new Mercedes model offers more than other cars of comparable size in this segment in all comfort-related respects, e.g. shoulder-room, legroom and headroom.
The diesel line-up is headed by the B 200 CDI with 103 kW/140 hp, which has a remarkably high torque of 300 Newton metres. The newly developed turbodiesel with common-rail direct injection accelerates the Compact Sports Tourer from nought to 100 km/h in 9.6 seconds, and from 80 to 120 km/h in 10.0 seconds (in fifth gear). The maximum speed of the B 200 CDI is 200 km/h. Despite this superb performance the fuel consumption remains below the six-litre mark at 5.6 litres per 100 kilometres (NEDC combined consumption). The CDI models in the B-Class meet the stringent EU 4 exhaust emission limits even without a particulate filter, though Mercedes-Benz offers a maintenance-free diesel particulate filter system on request.
The new B 200 TURBO and the CDI models B 180 CDI and B 200 CDI are equipped with a six-speed manual transmission as standard. The newly developed, continuously variable AUTOTRONIC automatic transmission is optionally available for all engine variants of the Mercedes-Benz B-Class.
The newly developed electromechanical power steering system generates its servo effect with an electric motor, varying it as a function of road speed. This means the servo action is greater at low speeds than at high speeds, which means that the steering is much lighter than a conventional system when parking or manoeuvring slowly. The parabolic rear axle is likewise a new development. It makes a major contribution to the stable, sporty and precise handling, as well as the excellent ride comfort of the new B-Class.
The improved Electronic Stability Program (ESP®) now has a new, additional function: the STEER CONTROL steering assistance system. This operates in tandem with the electromechanical power steering system, providing the appropriate servo assistance in critical handling situations to help the driver stabilise the vehicle. When braking on road surfaces offering less grip on one side than the other the new, additional ESP® function also helps with steering corrections and provides the driver with better road contact.
From the steering to the shock absorbers, from the brakes to the rear axle and from the Electronic Stability Program to the tyres - Mercedes engineers have rigorously tested all the components of the suspension system and employ the latest technology to achieve the best possible handling safety and high performance.
The McPherson strut principle which is so advantageous for front-wheel drive cars has been developed further: while the wheel is normally located by the spring strut, track rod and a camber arm with a transverse stabiliser, the front axle of the new B-Class features additional, rigid wishbones. These carry out the wheel location duties of the transverse stabiliser, which is connected to the spring struts by torsion bars and newly developed rubber bearings. This solution provides better suspension configuration possibilities - especially where elasto-kinematics and ride comfort are concerned - and also allow the castor angle and camber to be adjusted precisely. The wishbones consist of two welded steel shells and are attached to the integral member via large rubber bearings.
