First Look: 2011 Porsche 911 GT3 RS 4.0

The “ultimate” non-turbo 911?

by on Apr.28, 2011

The new GT3 RS 4.0 is the most powerful naturally-aspirated 911 Porsche has ever produced.

Faster than most folks can get “2011 Porsche 911 GT3 RS 4.0” out of their mouths, the Schwabian automaker’s “ultimate” normally-aspirated sports car will hit 60 – on the way to a top speed of 193 mph.

The appropriately named GT3 packs a new 4.0-liter flat-six in its rear engine compartment, the powerplant derived from 911 GT3 RSR race car, and borrowing such niceties as the forged pistons and titanium connecting rods.  A six-speed manual is the only gearbox offered.

The new Porsche also borrows a variety of race-derived parts designed to shed weight, such as carbon fiber seat frames, front fenders and luggage compartment lid.  Even the carpeting is “weight-optimized,” Porsche proclaims, trimming the 911 GT3 4.0’s total mass to just 2,998 pounds – with a full fuel tank.
