New Porsche 911 GT2 RS to Get Water Injection, Top 640 HP

–

Ever since Porsche confirmed the development of an all-new 911 GT2, we’ve been on the edge of our seats waiting for it to make its debut. The last GT2 RS was a rear-wheel-drive ball of fury that could sprint from 0 to 100 mph in 6.6 seconds and monster through any circuit with brutish force.

U.K. publication EVO got a chance to ride in a prototype of the GT2 RS with Porsche GT boss Andreas Preuninger, and he revealed a whole bunch of new info on the top-tier 911.

Let’s start with the powertrain. According to EVO, the engine is based off the same 3.8-liter flat-six found in the current 911 Turbo S, upgraded with revised engine internals, larger turbochargers, more boost pressure, and a titanium exhaust.

Also present in the new GT2 is a water-injection system that cools intake temperatures, much like the one found on the BMW M4 GTS. Power is said to be “greater than 641 horsepower and 553 lb-ft of torque.” For now, Porsche is stating a zero-to-60-mph time of “less than three seconds.”

–

Porsche confirmed back in March that the new GT2 will use a PDK exclusively, which makes sense considering the company’s RS-badged cars are built purely for speed. Like the last GT2 RS, this one will be rear-wheel drive only.

Thanks to use of lightweight materials such as Gorilla Glass, Preuninger says the new GT2 will weigh less than 3300 pounds. If customers want to drop the weight even further, they can option a 66-pound-saving Weissach pack, which includes featherweight magnesium wheels, a titanium roll cage, and a carbon-fiber roof.

Last month, Road & Track reported on mystery NACA ducts it spotted on a GT2 test mule. They’re there to funnel cold air straight to the standard carbon-ceramic brakes. Also standard on the car are active engine mounts, Michelin Pilot Sport Cup 2 tires, and an electronic locking differential.

–

EVO reported that development of the GT2 will be finalized throughout the next few weeks, which means an official reveal is just a few months away. We can’t wait.
