Porsche's high-performance flagship is here.

Porsche will fully introduce the 911 GT2 RS tomorrow at the Goodwood Festival of Speed that's taking place in England. An impatient fan has ruined the company's surprise by posting a full gallery of official pictures to an enthusiast forum.

Downloaded from a topic on Rennlist, the pictures confirm the high-performance flagship receives a specific front bumper with large air dam, a new hood that incorporates a pair of NACA ducts, a specific rear bumper, and a huge wing on the deck lid.

We also get our first look at the RS' interior. We see a pair of carbon fiber sport seats, carbon fiber trim on the door panels and the dashboard, and a full roll cage in lieu of the rear seats. Interestingly, a button on the center console labeled "ESC + TC OFF" suggests experienced drives will be able to turn the stability control and traction control systems completely off.

As we previously reported, the GT2 RS benefits from an evolution of the Turbo S model's turbocharged 3.8-liter flat-six engine. Applying lessons learned on the track, Porsche's GT division added two bigger turbos tweaked to provide more boost, a model-specific exhaust that's much lighter, and stronger internal components.

British magazine Evo has learned the GT2 RS receives a water-injection system that reduces intake temperature. Similar to what's offered on the BMW M4 GTS, the water-injection system bumps the flat-six's power output while improving efficiency and reducing wear on key components.

The GT2 RS is still at the prototype stage so final specifications aren't available yet. However, we know the six will send over 641 horsepower and 553 pound-feet of torque to the rear wheels via a dual-clutch automatic transmission.

We've heard rumors of 700 horsepower over the GT2 RS' rear axle, but nothing is official yet. Regardless, it'll be the most powerful street-legal, factory-built 911 ever. Porsche promises a zero-to-62-mph time of under three seconds.

"It's not just a chipped Turbo S, definitely not. It's a completely re-engineered car," said Porsche GT project director Andreas Preuninger in an interview with Evo. "[It's] a lot easier to drive than a 997 GT2 RS, which was a brute, to the point where you couldn't handle it sometimes," he added.

To save weight, Porsche has removed some of the sound-deadening material and replaced the glass with thinner Gorilla Glass. Buyers who want an even lighter car will be able to order the optional Weissach Package, which bundles magnesium wheels, a titanium roll cage, and a carbon fiber roof, among other go-fast goodies.

Porsche will begin pre-production of the 911 GT2 RS in the coming weeks, meaning the series-produced car is likely at least a few months away from hitting showrooms. Pricing will start in the vicinity of $200,000, a price which seemingly includes a matching flyback watch.

Want one? You're much too late. A recent report indicates production is limited to 1,000 examples worldwide, and every single example has already been spoken for.
