The new BMW 3 Series completes final tests at Nurburgring
19 Aug 2018|2,278 views
There was only one possible location for full driving dynamics testing and set-up runs - the legendary Nurburgring Nordschleife. A particularly extensive testing programme was developed for the camouflaged prototypes of the new BMW 3 Series.
The comprehensive development programme for the new suspension, steering and braking systems provided the engineers 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 development process for the new BMW 3 Series is geared towards enhancing the 'sports sedan' character of the car.
The centre of gravity is 10mm lower than in its predecessor, weight distribution is balanced at a perfect 50:50 and the total weight is as much as 55kg less. Meanwhile the rigidity levels of the body and suspension hard points - so crucial to the steering set-up and ride acoustics - are significantly enhanced.
The car's agility and steering precision benefit from the extended front and rear track widths, while increased wheel camber levels offer additional potential for maximum transverse dynamics.
In terms of the engine portfolio, one important feature is a thoroughly revised four-cylinder petrol engine. It is the most powerful four-cylinder engine ever to be fitted in a BMW series production model. Yet its fuel consumption figures are still some 5% below those of the predecessor engine, one contributing factor being the further developed eight-speed Steptronic transmission.
