As expected, the GT3 uses the wide-track 911 body of the existing Carrera 4 model, adding a more track-focused aerodynamic package.
This includes a unique front with pronounced splitter, wing mirrors, side skirts, and a rear with a new vent between the taillights and central exhausts.
A fixed rear wing appears on the rear, which raises questions about the active unit evident on earlier test mules.
The GT3’s headlights and front indicator/DRL housings have a unique tinted appearance, while the headlights themselves are a new dual-projector design.
Also pictured are centre-lock wheels and a carbon-ceramic brake package, though earlier sightings of mules with conventional five stud wheels suggests that the former will remain optional.
For the first time, Porsche has added active rear-wheel steering, designed to improve agility and stability. There's also a new electronically controlled and fully variable rear differential lock and dynamic engine mounts.
Power in the new GT3 is provided by Porsche's 3.8 litre flat-six engine - based on the same unit powering the Carrera S - producing 350kW of power at 8250rpm.
Matched to Porsche's seven-speed PDK auto and a rear-wheel-drive configuration, the 911 GT3 promises a 0-100km/h sprint time of 3.5 seconds. Top speed is listed at 315km/h.
By comparison, the outgoing GT3 - in its base 2006 form - featured a 309kW 3.6 litre six and a 0-100km/h time of 4.2 seconds.
An update appeared in 2009, upgrading the engine to a 3.8 litre 324kW six. More powerful GT3 RS and RS 4.0 models have also appeared, and will likely debut in the new line-up also.
Watch for Australian availability and details to be revealed in the coming hours.
