With an additional 80 horsepower & 37 pounds more torque, the 2018 Porsche 911 GT2 RS is officially the fastest and most powerful street-legal 911 ever built. Powered by a 3.8-liter water-spray twin-turbo motor, it produces a neck-snapping 700 horsepower and 553 pound-feet of torque. The interior is just as powerful: wall-to-wall red Alcantara leather and carbon fiber everywhere.
