Porsche has unveiled the Cayenne SUV hybrid prototype, providing a glimpse of what the company will offer to consumers by the end of the decade.
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 future developments may allow Porsche engineers to push towards an average fuel consumption figure of 8.9 liters/kilometer (approximately 26 miles per gallon).
The Cayenne Hybrid will feature a full-hybrid design where the hybrid module (clutch and electric motor) is positioned between the combustion engine and the transmission rather than having the hybrid drivetrain branching output along various lines and in various directions via a planetary gearset. Porsche selected this design because the in-line configuration of the hybrid components are more compatible with the existing Cayenne platform, this system in testing is more fuel efficient, and because this configuration is a better fit for Porsche as it will provide improved acceleration and engine flexibility compared to a conventional Cayenne.
