July 27, 2007 Porsche this week demonstrated a Cayenne SUV hybrid prototype, providing a glimpse of what the company will offer to consumers by the end of the decade. The Cayenne Hybrid features a full-hybrid design where the hybrid module (clutch and electric motor) is positioned between the combustion engine and the transmission. The design will improve acceleration and engine flexibility compared to a conventional Cayenne and Porsche is targeting average fuel consumption figures of 9.8 liters/100 kilometers in the New European Driving Cycle and about 24 miles per gallon in the US FTP cycle for the Cayenne Hybrid, and hopes future developments may allow it to push towards a consumption figure of 8.9 liters/kilometer (approximately 26 miles per gallon). 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.
