A well-placed Porsche source has just informed Autocar that the upcoming GT3 RS will be a "far greater step forward" over the current GT3 compared to how the previous-gen RS was to 997-era GT3. For starters, the new GT3 RS will be lighter and more powerful, with an output of at least 500 horsepower. For comparison, the previous-gen 911 GT3 RS 4.0 made 493 hp. Porsche has also done some major surgery to the car's suspension, and has even given it the wheels and tires from the 918 Spyder for better grip and traction. Expect a 0-62 mph time as low as 3.2 seconds, but top speed will remain the same at 196 mph.
