Porsche has unveiled the all-new 911 GT3 RS. The car was shown to the public during the Monterey Car Week and sales have already started in some markets.

The new 911 GT3 RS comes with substantial upgrades in cooling, aerodynamics, and, of course, the engine. The 4.0-liter boxer engine delivers 518 horsepower, and all the power is sent to the wheels via a seven-speed PDK transmission.

Thanks to some active aerodynamic elements, the car can produce 409 kilograms of downforce at 124 miles per hour and 860 kilograms at 177 mph. A first for the 911 is the new DRS system, which basically works like the one in Formula 1.
