The new BMW 3 Series Sedan - endurance test in the "Green Hell"
The next generation of the BMW 3 Series Limousine is just completing the crucial stages on the way to serial production maturity. There was only one possible setting when it came to driving dynamics testing and set-up runs: the legendary Nordschleife at Nürburgring. Test runs at the "Green Hell" traditionally serve as an endurance test for the drive and suspension technology of newly developed BMW models. A particularly extensive testing programme was developed for the camouflaged prototypes of the new BMW 3 Sedan. After all, the comprehensive renewal of the wheel suspension, steering, damping/suspension and brakes provided the developers with a broad range of opportunities to optimise ride comfort and dynamic performance, enabling the ultimate sports sedan for the mid-range premium segment to mature lap by lap.
The underlying concept of the four-door model shows just how much the development process for the new BMW 3 Series Sedan is geared towards enhanced sporty flair. The centre of gravity is some 10 millimetres lower than in the predecessor model, axle load distribution is balanced at a harmonious 50 : 50 and the total weight adjusted for fittings is as much as 55 kilograms less. Meanwhile the rigidity levels of the body structure and suspension attachment – so crucial to the steering set-up and ride acoustics – have been significantly enhanced. The car's agility and steering precision benefit from much expanded track widths, while increased wheel camber levels offer additional potential for maximum transverse dynamics.
