The next generation Porsche Boxster has been caught testing yet again at the famous German race track, the Nurburgring. And seeing as though the sportscar has been mostly unwrapped, we think it's safe to say that it's in its final stages before its official launch in March at the 2011 Geneva Motor Show.

From these new spy shots, we can finally take a good look at the front of the vehicle as well as the doors, even though the real dirt on the Boxster->ke570 is the fact that it has grown in length to make room for the "baby Boxster."

Under the hood the Boxster will use a slightly revised version of the 310-HP 3.4-liter six-cylinder engine, but rumors suggest that it might receive an advanced four-cylinder engine producing about as much horsepower as the current 2.9-liter six (255): "A Boxster with a four-cylinder engine, or maybe even a three-cylinder turbo, could produce between 180bhp and 200bhp and emit just 180g/km of CO2," said Hans-Jurgen Wohler. "Given the Boxster’s history – that it started with a 200bhp, 2.5-liter engine – I think this is possibly something that customers could accept."

Production is scheduled to start in early 2012, this time in Stuttgart and not in Finland as the current generation.
