The new Porsche 911 GT3 RS comes with all the aero tricks in the book


Porsche’s latest 911 GT3 RS is here and with the looks of it, there’s no doubt that means business.

Rather than throwing a ton of power at the new RS, Porsche has instead focused on aero and cooling by taking proven features of the track-only 911 GT3 R and applying them to this road-racing car. .

Aerodynamics and cooling
First on the list of new additions is a larger radiator in the nose where the frunk of a normal 911 would be, replacing the usual setup of three smaller units. Like many aspects of the new RS, this comes from the 911 RSR and 911 GT3 R racing cars and leaves more room for active aerodynamics at the front.

Active elements in the nose maintain maximum grip and direct air to the radiator while pressure in and around the wheel arches is managed by a combination of blades and vents above and behind the front wheels. The cooling setup is so efficient that the inlets in the rear wheel arches are now just for aero channeling and no longer needed to keep the 518-hp flat-six happy in the back. The rear wheel arches feature a similar arrangement of slats and vents to the fronts.

Then we come to the absolutely massive, DRS-capable gooseneck rear wing. Featuring a fixed main section and a movable upper section, the DRS can be deployed with the press of a button on the steering wheel for straight-line speed, and can also act as an air brake in cooperation with the front flaps in case of strong deceleration.

It all adds up to give twice the downforce of the car it replaces and triple that of the “normal” 911 GT3: 900 pounds. at 125 mph and 1895 lbs. at 177 mph. Probably quite handy around corners then.

This aerodynamic attachment penetrates the bowels of the RS, with Porsche engineers believing that “the wheel arches of the new 911 GT3 RS are subjected to powerful airflows”. To manage and exploit these flows, the new GT3 RS has a suspension designed with “teardrop profiles” that generate 88 lbs. downforce on the front axle at high speed. If that doesn’t make you smile… you’re probably not a big nerd and you have a busy life.

For the rest of us, Porsche engineers have tweaked the RS’s front and rear suspension to “significantly reduce pitching under braking”, while the rear wheel steering has also been revised.

There are three driving modes: Normal, Sport and Track, the latter allowing the driver to adjust the compression and damping behavior of the car’s front and rear suspensions on the fly via a motorsport-derived operating system. . There is also a dial on the steering wheel to adjust the rear differential.

New camshafts with more aggressive cam profiles boost power from the naturally aspirated four-liter flat-six to 518 horsepower while the seven-speed PDK gearbox gets shorter ratios than the GT3 for acceleration. more explosive. Dedicated air intakes on the underbody keep the drivetrain cool during the extended trail work the RS was designed for. The 0-60mph sprint takes 3.2 seconds and at full throttle the GT3 RS will do 184mph.

Wheels and brakes
The RS gets slightly larger brakes than the GT3 with Porsche’s ceramic composite discs available as an option. A set of light-alloy forged center lock wheels come standard, but shell out extra for the Weissach set and you have the option to shell out again for a set of featherweight forged magnesium kicks that allow for save an extra 18 pounds.

Speaking of lightweight materials, Porsche has used carbon fiber reinforced plastic extensively on the RS with the door skins, front fenders, bonnet, roof and bucket seats made from this material, giving the GT3 RS has a base weight of 3268 pounds.

The Clubsport package can be optional at no extra cost by adding a steel roll bar, fire extinguisher and six-point harness for the driver. The Weissach package comes at extra cost but gives exposed carbon on the roof and aero parts as well as replacing the front and rear anti-roll bars and roll cage with CFRP versions for further weight savings.

Porsche’s latest and greatest road race car starts at $233,577.61.
