The top-dog GT3 RS variant joins the lineup this year, complete with a massive rear wing, a race-car aerodynamic package, and a 518-horsepower version of the naturally aspirated 4.0-liter flat-six engine. The GT3 RS looks insane, a video-game race car come to life, and we expect it to hit 60 mph in under 3.0 seconds when we get our hands on it at our testing facility.
The GT4 RS shares its naturally aspirated 4.0-liter flat-six in with the 911 GT3, and it makes 493 horsepower and 331 pound-feet of torque, 9 horsepower and 15 pound-feet less than the GT3.
