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.
