There’s a lot of hype about new power trains and lightweight plastics, but traditional materials are sure to play a big, if not leading role, in making cars more fuel efficient. The new models on display at the International Motor Show Sept. 19-27 in Frankfurt are a case in point. Ten of the models from Audi, BMW, Opel, Peugeot and Renault use Hydro aluminum components and systems. Examples include:
Opel Astra, front and rear bumper beams;
Rolls-Royce Ghost, front end;
Audi R8 Spyder, rollover protection system; and
Peugeot 5008 MPV, rear bumper.
In addition, Hydro is supplying flat-rolled aluminum strip for body parts to the new BMW 5 series, the Mercedes-Benz E-class station wagon and all versions of the new C-class model, as well as the current Porsche Panamera.
Hydro supplies the aluminum content pictured above for several BMW models, including the new “small” Rolls-Royce.
