Since Porsche introduced the latest version of its 911 range, hardcore enthusiasts have been patiently awaiting the inevitable higher-performance models while Stuttgart distracts everyone else with special-edition Cayennes and the new Panamera sedan. But now that the latest GT3 has been released, only the most powerful versions await an update. Up next are the track-focused GT3 RS, the force-fed Turbo and the grand-daddy of 'em all, the GT2. The latter variant has just been spied, although you'd be hard-pressed to tell the difference from the outgoing model from looking at it.

In addition to the minor tweaks given to the entire 911 range, the next GT2 will reportedly benefit from some additional engine tuning. A new direct injection system, bigger combustion chambers, upgraded crankshaft and new oil and water pumps. Together, the package is expected to help bring output up from the current 530 horsepower to 550, enough to propel this Carrera to 60 mph in about 3.5 seconds. Rumors are still afoot that an even more powerful version – dubbed the GT2 RS – may be under development as well, but in the meantime, we're anticipating the latest 911 GT2 to bow at the Frankfurt Motor Show in the Fall.
