2010 Porsche Panamera Turbo

Having already leapt into the SUV space with its controversial Cayenne, Porsche decided to fill the gap between sports car and utility vehicle with the launch of its Panamera luxury sedan.

First shown in 2009 at the 13th Auto Shanghai, the Panamera has no shortage of luxury or high-tech features. The exterior styling is controversial to say the least, yet it looks at home in the Porsche lineup. The interior is less daring, but should help raise the bar in the grand touring luxury segment.

The entry-level powerplant will be Volkswagen's 3.6-liter six-cylinder engine with 300 horsepower. The 'S' model will deliver 400 hp from a 4.8-liter V8, and the Turbo variant will offer an estimated 500 horses. The Panamera S will start at $89,000, while the all-wheel-drive 4S will cost $93,800. The Turbo will ring in at $132,600, which is slightly more than a Cayenne Turbo. U.S. sales are to begin in October.
