BMW EfficientLightweight has the highest priority with M vehicles. That is because low weight is the basis for outstanding driving dynamics and exemplary efficiency.
BMW M has consistently applied this insight to vehicle construction – and has been continually refining it. Our engineers constantly ask themselves: Where does it make sense to reduce weight and where does it not? The result: BMW EfficientLightweight.
This involves the use of ultra lightweight materials such as CFRP (carbon fibre reinforced plastic), magnesium or aluminium in targeted areas of the car. For example, the single-piece CFRP drive shaft minimises rotating mass and a CFRP precision strut brace provides significantly higher rigidity than aluminium but with a lower weight. In the front bonnet, light materials in the front side walls, crossmembers and steering wheel frame also reduce weight.
All of this reduces vehicle mass and lowers the car's centre of gravity while maintaining the highest safety standards, achieving greater agility and dynamics in curves and improving acceleration and braking.
