Last weekend's Rennsport gathering at Laguna Seca Raceway is the place where Porsche showed off its newest and most insane 911, the Porsche 911 GT3 R rennsport.
This 611-horsepower track toy will be limited to 77 units. There are all kinds of exterior and interior styling bits, too -- such as LED rear lights and interior monitors fed by exterior cameras.
This really is a racecar -- the safety features are compliant with FIA standards and the car has a roll cage and only a single seat for the driver.
There are 18-inch racing wheels, of course, and a sequential six-speed constant-mesh gearbox that gets power to the rear wheels.
Since this is a track car, it has a race-ready chassis, suspension, and brakes.
