In an industry conference held in Germany (Esslingen) just a few days ago, the Schaeffler Group, together with Porsche, presented an interesting basis of the Cayenne prototype, called CO2ncept-10%. This conference focuses on “reducing friction in the powertrain.

This strange name is because the objective is to reduce by 10% in fuel consumption and CO2 emissions. Schaeffler will assemble the elements and Porsche adjustment of the whole.

The engine of the Cayenne is still a V8, but thanks to Schaeffler transmission and suspension are completely new, they make the vehicle significantly reduce their consumption and rates of friction between moving parts.

The greatest reduction in consumption was achieved in the engine, a 5.8% overall, thanks to the use of electromechanical valve tappets and less friction in the drive belts and valve seats.

Also were replaced with tapered roller bearings in the differential by others using two rows of needle roller bearings, this gives the engine a 1.1% savings, and one of the most important things is that they replaced the stabilizer hydraulic other electromechanical control.

Finally control components electric power now only required when in operation.

Dr. Robert Plank, Manager of Engineering for the Schaeffler Group, said: “This project is a good example of successful cooperation between automakers and suppliers. This cooperation reduces development time, avoiding redundancies and makes an important contribution to competitiveness.
