The next generation 911 is on its way to make its debut. The test mules of the car were recently spotted testing at an autobahn and the Nürburgring racetrack. It is being said that a 3.8 liter flat siz with a tri turbo induction system will power the new range of the 911. While the 911 should have 520hp of power at its disposal, the S should have around 550 horses to play with. Check out the video to see the next gen cars in action.
