Spy pics show front air intakes and trim around rear exhaust of the next-generation 2012 Porsche Boxster.

Here are the latest spy pics of the upcoming 2012 Porsche Boxster doing some test laps around the track at the Nurburgring circuit.

There is more to see of this Boxster prototype than the last time it was spotted out in the open. Much of the front fascia of the vehicle can be made out from behind the limited camouflage. In these shots, we can also clearly see the new front air-intakes.

At the back too, we can distinguish some the Boxster's features. Notice the thinner trim around the centrally mounted double exhaust pipes.

We've previously reported on how Porsche would like to dial back the Boxster's CO2 emissions number to below 180 g/km. In order to achieve that, Porsche is considering a turbocharged 3-cylinder engine for the Boxster.

Somehow, though, it's hard to imagine any Porsche, historically always an Olympian on the track, being propelled by a 3-cylinder power plant.

The next-generation Porsche Boxster is expect to debut sometime in late 2011.
