The dynamics story of the BMW M5 Competition

0

Markus Flasch, CEO of BMW M, presents the 2020 M5 Competition model, featuring a 625hp, 4.4-litre V8 turbocharged engine, and a specially tuned chassis, which includes double-wishbone front suspension and five-link rear suspension. The dynamics team at M division applied their experience gained in the development of the BMW M8 Competition Gran Coupé.

Notable features include:

• Bespoke engine mounts, with a spring rate of 900N/mm. The engine’s firm connection to the vehicle’s structure results in extremely fast engine response and immediate transmission of its power to the drivetrain. The stiffness of the mounts also helps the car turn into corners with greater precision.

• The camber at the front axle has been specified to enhance the car’s ability to absorb lateral forces through high-speed corners, while fitting the toe links with ball joints instead of rubber mounts has resulted in highly precise wheel guidance at the rear axle. The high spring rate of the rear anti-roll bar allows the body roll that occurs through high-speed corners to be distributed with a pronounced rear bias.

• The M Performance chassis from the extensive M Performance Parts range gives the BMW M5 Competition an even sportier and more individual setup. The reduction in ride height of between 5 and 20mm enabled by the coilover suspension results in a lower centre of gravity, which reduces body roll and enables higher cornering speeds. Damper adjustment is independent for compression and rebound.

• The M5 Competition is equipped with M Compound brakes, which are significantly lighter than conventional cast-iron units. At the front, there are perforated, inner-vented brake discs with six-piston fixed callipers. The rear brakes feature single-piston callipers with an integrated parking brake
