The new generation Porsche 911 GT3 is set to be unveiled sometime at the end of 2012, most likely at the Los Angeles Motor Show. This means that the company is currently very busy testing the car and we all know that wherever there's a car testing, there is also a spy photographer. So ,here's the latest video of the future 911 GT3.

The 911 GT3->ke617 will be powered by a normally aspirated 3.8-liter flat six engine with an output of 450 HP - an increase of 15 HP over the current version. The next GT3 won't be offered with a manual transmission, meaning that customers will only enjoy a PDK gearbox. It is believed that top speed will be somewhere in the 200 mph area, while the 0 to 60 mph sprint will be made in about 4 seconds.
