54 years of 911 development have lead to this. Millions of miles over five decades on race tracks, rally courses, and everyday public roads were all a proving ground for the pinnacle of the storied 911 — the 911 GT2 RS. Put aside the fact that it's the most powerful 911 ever produced for a moment. The GT2 RS is also the most technologically advanced: a revised aerodynamic package, extensive use of carbon fiber and magnesium, world-class suspension, rear-wheel steering, and ceramic composite brake rotors. But the heart is, of course, the venerable flat-six motor. This revision displaces 3.8 liters and uses dynamic twin turbochargers to deliver a staggering 700 hp and 553 lb-ft of torque, enough to blast from naught-to-60 in 2.8 seconds with a top speed of 211 mph — the most ever from a street-legal factory 911. The GT2 RS won't be the final word on the 911, but it's the boldest yet from Stuttgart.
