Hot off the world debut of its all-new 2011 Cayenne SUV in Geneva, Porsche will fittingly be debuting the new hybrid version at the New York show next week.

Designed primarily as a way to reduce fleet emissions in the U.S., the Cayenne Hybrid is powered by the same advanced hybrid drivetrain as its platform-mate, the 2011 Volkswagen Touareg Hybrid. That means a 333-horsepower supercharged V-6 from the Audi S4 and a 47-horsepower electric motor can be found underhood, paired by a decoupling clutch to allow each to run independently. Combined, the two power sources make a solid 380 horsepower and 428 pound-feet of torque and run through an eight-speed automatic transmission.

The Cayenne S Hybrid features a 'hybrid controller' system that coordinates the two drive units through the center clutch, enabling the SUV to be driven up to nearly 40 mph on electric power alone. As we mentioned in our First Drive article, the Cayenne S Hybrid can also coast on the freeway at speeds up to 86 mph using only electric power. The Porsche's infotainment display monitors power usage and alerts the driver as to which mode the Cayenne is running in - combined gas/electric, or one of those two alone.

Pricing has yet to be determined and we expect to hear more in that regard when we get closer to the Cayenne S Hybrid's U.S. showroom launch this fall. For live coverage of this and other New York show vehicles, stay tuned on March 31 and April 1.
