At the 2014 Geneva Motor Show, BMW showcased an M4 clear construction model. The “see-thru” M4 gives us a look at the chassis and lightweight materials and techniques used to design the new M4 Coupe. An all-embracing lightweight design concept keeps the cars’ weight to just under 1,500 kilograms.

Back in 2013, Norbert Siegl – M3/M4 Program Manager, Engine – and Albert Biermann – VP, Engineering M – told BMWBLOG that the weight-loss regimen had been in place for the development from the start, the goal being to meet or beat the weight figure for the E46 M3, i.e. sub-1,500 kg or 3,300-ish pounds. The other point they were eager to press is that these new-gen cars took more inspiration from the racing GT2/4 and GTS street model of the E90/E92/E93 fourth generation.

Low weight and a high level of structural rigidity are the M4 provides an ultra-dynamic driving experience. In the double-joint spring strut front axle alone, the use of a lightweight aluminium construction for components such as control arms, wheel carriers and axle subframes saves five kilograms over a conventional steel design.

The roof, roof center bow support, front fascia, rear fascia, trunk liner pieces, and front strut brace are all in CFRP to save weight and add rigidity to the whole.
