Extensive, model-specific lightweight design measures play a major part in moulding the performance qualities and exclusive character of the new BMW M3 CS. The use of components made from carbon fibre-reinforced plastic (CFRP) both inside and out is of key importance here. Besides its carbon fibre roof, the special-edition model also uses this lightweight, high-tech material for its bonnet, front splitter, front air intakes, exterior mirror caps, rear diffuser and rear spoiler. Its centre console, the shift paddles on the steering wheel and its interior trim strips are likewise all manufactured from CFRP. The standard M Carbon bucket seats also do their bit to keep weight down in the cabin. The titanium rear silencer, meanwhile, shaves more than 4 kilograms off the weight of the exhaust system fitted on the new BMW M3 CS. The various lightweight design measures bring about a total weight saving of some 20 kilograms compared to the BMW M3 Competition Sedan with M xDrive.
Body rigidity can be further increased by specifying a package of high-precision strut braces for the engine compartment that have also been engineered for lightness. The cast aluminium elements connecting the spring strut towers to the front end feature a weight-optimised geometry that has been precisely matched – with the help of numerical models – to the forces applied in various driving situations.
The driver and front passenger are welcomed as standard by M Carbon bucket seats in a model-specific design. Fully electric and heated, they feature integral head restraints along with an illuminated model badge, resulting in a unique blend of racing flair and long-distance comfort. The use of CFRP in the structural elements of the seat cushion and backrest as well as the eye-catching cut-outs in the side bolsters and below the head restraints are testimony to the seats’ weight-minimising construction.
