Porsche demonstrates Cayenne SUV hybrid prototype

July 26, 2007

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).

Coordinating the car’s three main components – the combustion engine, the electric motor and the battery – is the Hybrid Manager, the heart of the Cayenne Hybrid. The Hybrid Manager, which oversees some 20,000 data parameters as compared to only 6,000 data parameters for a conventional engine, is one of the most powerful technologies found in any hybrid vehicle.

Other unique features of the Cayenne Hybrid designed to decrease fuel consumption include the power steering and vacuum pump for the brakes, as well as the air conditioning, which operate on electric power. Technical components, such as the oil pump in the Cayenne’s automatic transmission, have been replaced by electrically powered units. The Cayenne Hybrid’s electro-hydraulic steering – a first for a vehicle of its kind, will ensure the Cayenne Hybrid drives like a Porsche with predictable and safe handling characteristics and the agility that is expected of a Porsche SUV.

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.

Porsche Cars North America, Inc. (PCNA), based in Atlanta, Ga., and its subsidiary, Porsche Cars Canada, Ltd., are the exclusive importers of Porsche sports cars and Cayenne sport utility vehicles for the United States and Canada.

They, in turn, provide Porsche owners with best-in-class service.
