2010 Porsche 911 Turbo revealed, spec'd--photos

As usual, according to Porsche,the new 911 Turbo is all-new, yet delivers a vehicle that--at a glance--is indistinguishable from the old model. This is a good thing for 911 purists. But if you didn't like the old model's bug-eyed look, the new one won't sit any better with you.

While the new 911 Turbo benefits from the World's Most Subtle face-lift, the biggest changes are measured not with the eye but with a stopwatch.

Under the 911 Turbo's familiar decklid is a 3.8-liter turbocharged and direct injected engine good for 500 horsepower and up to 516 pound feet of torque.

The drop top Turbo Cabriolet will debut simultaneously with the Turbo Coupe.

The 911 Turbo's drivetrain is an alphabet soup of systems working together. DFI and VTG help the engine to operate powerfully and efficiently. PDK selects the gears and a combination of PTV, PTM, and PSM keep the power and grip in check. That's a mouthful.

What this means is that the 911 Turbo blows by 60 mph from a stop in 3.2 seconds before hitting a top track speed of 194 mph.

The new Porsche 911 Turbo will debut in Coupe and Cabriolet configurations at the 2009 Frankfurt auto show.
