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 lb-ft is reached 
at 5,750 rpm.
The Porsche 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 2012 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 Porsche 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.
The limited edition 2012 
Porsche 911 GT3 RS 4.0 is 
painted Carrara White as standard and emphasizes its proximity to motor racing 
by its dynamic appearance. Signature characteristics are the wide track, the low 
vehicle position, the large rear wing with side plates, central twin tailpipe, 
and the aerodynamically optimized body. Air deflection vanes mounted on either 
side of the front bumper - called 'flics' or dive planes - make their first 
appearance on a production Porsche. They create increased downforce on the front 
axle, and together with the steeply inclined rear wing, provide aerodynamics on 
par with its performance capabilities. As a result, at the 193 mph top track 
speed, aerodynamic forces exert an additional 426 lbs of downforce, thus pushing 
the 911 GT3 RS 4.0 onto the road.
With a manufacturer's suggested retail 
price starting at $185,000 (excluding destination), the 2012 Porsche 911 GT3 RS 
4.0 goes on sale in the United States in late 2011.
