Schaeffler Group Presents CO2ncept-10% Cayenne

Porsche and the Schaeffler Group joined forces to create the CO2ncept-10% vehicle for the ATZ/MTZ Congress held on December 9-10 in Esslingen. The main idea is “Friction Reduction in the Powertrain” which can get lower fuel consumption and CO2 emissions.

The base car was a Porsche Cayenne with a V8 engine. Schaeffler and Porsche changed different engine and differential components which make that car more fuel efficient. The most important change was switching some hydraulic systems with electromechanical ones, and this had a big impact.

“As in the case of the cam phasers, the electrically operated components make such an important contribution because they require energy only when their operation is requested,"
explains Dr. Robert Plank, Manager of Corporate Engineering for the Schaeffler Group. “In hydraulically controlled systems, the pumps have to maintain pressure permanently, resulting in much higher energy requirements.”

“This project is a good example of the successful cooperation between automobile manufacturers and suppliers. This cooperation reduces development times, avoids extensive redundancies and makes an important contribution to competitive ability,”
says Dr. Robert Plank.

“To us, the CO2ncept-10% is impressive proof of a continuing optimization potential that is also closely related to volume production. This is not the end of the line though. CO2ncept-10% is the sum of its components, and these components are only a few from the Schaeffler Group’s portfolio that allow similar levels of energy efficiency optimization to be reached for vehicles from other segments.“
