The entry-level Cayenne maintains its 3.6-liter V-6, but thanks to a few tweaks and eight-speed transmission, it gets 10 more horses (for a total of 300-horsepower) and is 20 percent more fuel efficient on the combined European cycle. Occupying the middle ground is a more powerful 400-horsepower (up 15 ponies) Cayenne S. Its 4.8-liter V-8's fuel efficiency is 23 percent better than last year's model. Same goes for the Cayenne Turbo's 500-horsepower V-8. Interestingly, there was no word on the autobahn-eating 550-horserpower Turbo S or sportier GTS.

The modern design continues inside. With more room to work with, engineers implemented a high center console between the two front passengers. Like the Panamera, it bears an elongated form, with a litany of control buttons set below and on either side of the Tiptronic lever. The leather dash gets a TFT screen capable of controlling all the pertinent in-cabin goodies. It's flanked by tall aluminum-surrounded HVAC vents. The whole is attractive, in true Porsche style.

Porsche's 2011 Cayenne will first bow at next week's Geneva motor show, followed by a North American debut at the New York Auto Show in April. U.S. Cayenne S and Turbo sales are scheduled to begin in July, while standard Cayenne and the Cayenne S Hybrid arrive this fall. Expect full details and pricing to arrive nearer to its U.S. sale date.
