It produces 518 horsepower (386 kilowatts) thanks to new camshafts with modified cam profiles, featuring a motorsport-derived single-throttle intake system. Porche routes the car’s power through its seven-speed PDK gearbox

To achieve peak aerodynamic performance, every body panel of the RS is special—even the door skins are carbon fiber.

The aero theme continues underneath, where teardrop-shaped control arms on the front axle improve wheel-well airflow. The lower control-arm ball joints are repositioned lower to reduce dive under braking. The ability to individually adjust the compression and rebound stages of the front and rear dampers via steering-wheel controls.

The extra width translates over to the car’s suspension, which couldn’t escape aerodynamic scrutiny. Porsche designed the car’s double-wishbone front axle with teardrop-shaped profiles that increase the downforce by 88 lbs.

Track mode allows the driver to adjust basic vehicle settings, like the front and rear axle damping, the rear differential, and more. The steering wheel features four rotary controls for individual settings and a dedicated DRS button. 

Porsche 911 GT3 RS combined the three radiators into a single heat exchanger mounted at an angle in the front cargo area—make that the former cargo area.

Carbon-ceramics are optional. Forged aluminum wheels are standard, wearing 275/35-20 rubber up front and steamroller 335/30-21s out back. The Weissach package unlocks the option of magnesium wheels.
