LIGHT, STABLE AND SAFE:

THE PASSENGER CELL

IN HIGH-TECH CARBON.

CARBON FIBRE REINFORCED PLASTIC (CFRP) REVOLUTIONISES

LIGHTWEIGHT CONSTRUCTION.

Innovative in every detail.

Thanks to BMW EfficientDynamics research,

the BMW engineers were able to balance out the extra weight of the

lithium-ion high-voltage battery with extensive use of aluminium and

carbon components.

This can be seen, in particular, in the use of the innovative material carbon.

Despite its lightness, carbon ensures the enormous strength, stability and

therefore safety of the passenger compartment (Life module). Its use is

also immediately noticeable in the exceptional handling, outstanding

roadholding and eager acceleration of the BMW i.

For a long time, the use of carbon for a passenger compartment was

effectively impossible because it had to be built by hand, so the costs

were simply too high. Now, however, BMW i has redefined automotive

manufacturing by independently developing the first production version.

The weight saving from using carbon instead of steel is to up to  per

cent. Compared with aluminium, it’s up to  per cent.

But carbon components don’t just revolutionise lightweight construction.

They also allow new forms in car design because the carbon-fibre

reinforced polymers are almost as flexible as textiles. So while the carbon

body of the BMW i exemplifies good use of space, it also has an

optimised design, as the outstanding drag coefficient (Cd) of . proves.
