The 2010 Porsche 911 GT3 has been spotted testing on some appropriately curvy mountain roads, showing off its new "evolutionary" design. And by evolutionary, we mean pretty much everything on the new 911 GT3 looks like it does right now. Sure, there are some tweaks on the front air dam and to the rear lights (first shown on the 2009 Porsche 911), but style-wise, no new ground broken with this update. Under the hatch, however, is where the real magic may be being made. We're expecting to see an engine with direct fuel injection, either mated to the current GT3's 3.6-liter flat-six, or a tuned-up 3.8-liter flat-six from the new 911 — potentially bringing the new GT3 to the 440 HP neighborhood. Either engine could possibly be coupled to a seven-speed DSG gearbox, marking an evolutionary step in the right direction. We're expecting this newest GT3 to show its stuff at either the 2009 Geneva Motor Show or Frankfurt Auto Show, so until then you'll have to sit tight for the full details. [Automobile]
