Porsche 911 GT2 RS gets water injection, makes more than 641 horsepower

The 997-generation Porsche 911 GT2 was a sort of mashup between the track-ready 911 GT3 and the softer, more comfortable, and more powerful 911 Turbo. The RS model remains one of the most powerful cars Porsche has ever produced. It's been more than five years since that car went out of production, but a new model is finally on the way. Evo was lucky enough to ride along in the new 991-generation GT3 RS, and it's apparently even faster and more over the top than before.

According to Evo, the new GT2 RS will have the same basic format of the last model. It will use the twin-turbocharged 3.8-liter flat six from the 911 Turbo S, cranked up to at least 641 horsepower and 553 lb-ft of torque. For reference, the last model cranked out 612 horsepower from a turbocharged 3.6-liter flat six. To aid the engine, Porsche will introduce a water injection system similar to the one used in the BMW M4 GTS.

Andreas Preuninger, head of GT car development, told Evo that the engine isn't simply a Turbo S engine with more boost. Though it will have more boost, the engine also gets beefed-up internals, larger turbochargers, and a titanium exhaust. Like before, it will send all that power just to the rear wheels, though only through Porsche's PDK dual-clutch transmission. Some might complain about the loss of a manual, but RS models have always been about flat-out performance and lap times.

PDK means the GT2 RS can use Porsche's locking differential which will help manage all that power. Weight will be down compared with other 911s, though final measurements haven't been revealed. Preuninger says the final number will be below 3,300 pounds. The car will also make extensive use of aero tweaks, including a large rear wing, and carbon ceramic brakes as standard equipment.

Development is finally wrapping up, meaning we could see the car sometime this summer. There's no word on pricing, but expect the new model to cost well over $200,000.
