These appear to be the first photos of the 2012 Porsche 911 (Codename: 991), the new, 400-hp generation of Porsche's famous ass-engined sports car.

These photos, if they're real, show another gentle generational redesign, incorporating a similar ovular headlight design as the outgoing 997 with a more dramatic LED foglight package extending out beyond the Cayenne-esque grille openings, compete with LED turn signals similar to what we'd expect to find on an Audi.

In profile the car looks similar to the previous generations, carrying over the same big rear that makes the Porsche 911 iconic and different, though this time it's 2.5 inches longer. Speaking of the back-end, the 911 now has an extremely narrow slit of a taillamp wrapping around the back-end of the car.

Most dramatically, the interior finally catches up to the rest of the Porsche lineup with the long, raked center tunnel design launched on the Panamera. The multi-gauge cluster that's a hallmark of the 911 remains intact.

As we previously reported, the Carrera model launches with the 3.4-liter boxer-six it shares with the Boxster S, good for 350 horsepower. The new Carrera S, pictured in these photos, now has 400 horsepower from its 3.8-liter six. A hybrid version is on the way, but isn't pictured.

What do you think? Has Porsche successfully evolved the form without ruining it?
