Atlanta, Georgia – Porsche has unveiled a Cayenne SUV hybrid prototype, which it says provides “a glimpse of what the company will offer to consumers by the end of the decade.” The prototype was demonstrated to the media in Stuttgart, Germany.
Porsche is targeting average fuel consumption figures of 9.8 L/100 km and says that future developments may allow engineers to push toward an average of 8.9 L/100 km. The Cayenne Hybrid will feature a full-hybrid design, with the hybrid module positioned between the combustion engine and transmission; the company says it selected this design because the in-line configuration of the hybrid components is more compatible with the existing Cayenne platform, is more fuel efficient, and will provide improved acceleration and engine flexibility when compared to a conventional Cayenne.
Other features designed to decrease fuel consumption include an electric brake vacuum pump, electric air conditioning and electro-hydraulic steering, a first for a vehicle of its kind. Porsche plans to introduce similar hybrid technology in a version of its Panamera four-door Gran Turismo; the Panamera will debut in 2009, with a hybrid to follow.
