Powering the new Porsche 911 GT3 RS  models is a liquid-cooled six-cylinder Boxer engine with four-valve technology and enhanced VarioCam variable valve timing. The new Porsche 911 GT3 RS  produces an impressive maximum engine speed of 8,500 rpm.

In the new Porsche 911 GT3, the engine has 435 hp from a total displacement of 3,797 cubic inches, enabling an output of 114 hp per liter. The maximum torque is 317 lb.-ft. at 6,250 rpm. The 911 GT3 accelerates to 60 mph in 4.0 seconds with a top track speed of 194 mph.

The 3.8 liter engine in the new Porsche 911 GT3 RS  delivers even more power: 450 hp. The output is 118 hp per liter. This added power is due to the two new double-flow air filter housings and the new variable intake manifold with bigger intake tubes than those used on the 911 GT3. The greater flow of air increases engine power. The maximum torque of 317 lb.-ft. is reached at 6,750 rpm.

When pressing the SPORT button, standard in both models, temporarily increases low-end torque up to 35 lb.-ft. in the middle engine speed range.

The new Porsche 911 GT3 RS  passes 60 mph mark in 3.8 seconds. Short ratios increase the acceleration potential in all six gears. Consistent aerodynamics, designed for down force, allow high cornering speeds and excellent driving stability and performance. The top track speed is still an impressive 193 mph. The 911 GT3?s weight to power ratio is 7.1 lb per hp. In the new 911 GT3 RS it is 6.7 lb per hp.

Increased power and performance ? but with fuel consumption that match that of the 911 GT3. Both engines also meet the stringent requirements of the LEV II emissions standard.
