Great spy videos here of the Porsche 911 GT3 and the Porsche 918 Spyder. A must see!
The hardcore 2013 Porsche 911 GT3 test car was spied on camera in and out of the Nürburgring racetrack.
The 918 Spyder, which was snagged in Spain this time, is a different and far more expensive beast altogether. Among other innovations, it sports a plug-in hybrid powertrain that links a mid-mounted 4.6-liter V8 to an electric motor on each axle for a total system output of more than 760 horses.
