The motorsport-derived 4.0-liter engine, already the highest displacement 911 engine ever, also features the highest per-liter output -- 125 horsepower (hp) per liter -- from a naturally aspirated Porsche flat-six engine. The engine uses forged pistons, the connecting rods are fashioned from titanium, and the crankshaft has been lifted unchanged from the 911 GT3 RSR race car. It achieves its maximum power of 500 hp at 8,250 rpm. Maximum torque of 339 ft/lbs is reached at 5,750 rpm.

The 911 GT3 RS 4.0 offers truly impressive performance, lapping the famed Nürburgring-Nordschleife in 7 minutes and 27 seconds. Available exclusively with a six-speed manual transmission, the 911 GT3 RS 4.0 sprints from 0 to 60 mph in only 3.8 seconds, and with its gearing designed for the race circuit it reaches the 124 mph mark on the race track in under 12 seconds.

The 911 GT3 RS 4.0’s outstanding driving dynamics come from numerous, meticulously coordinated details. In addition to using suspension components typically encountered in motor racing, weight reduction is also of supreme importance. Equipped as standard with lightweight components such as light but strong carbon fiber sport bucket seats, carbon fiber front fenders and luggage compartment lid, and weight-optimized carpets, the two-seater’s ready-for-action weight is just 2,998 lbs with a full fuel tank. The 911 GT3 RS 4.0’s power-to-weight ratio is 5.99 lbs/hp.
