Just look at that mean appearance

Porsche 911 GT3 R

Only a few short months after Porsche revealed the track-ready yet road-legal 911 GT3 RS production sports car, the German carmaker has now unveiled the customer race car version for the various GT3 series around the world: the 911 GT3 R.

The GT3 R carries over many elements from the GT3 RS, like the distinctive double-bubble roof. It also enhances the lightweight aluminum-steel composite body design of the roadgoing GT3 RS by having the roof, the front cover and fairing, the wheel arches, the doors, the side and tail sections, and the rear cover constructed of carbon-fiber composite material. Even the windows--including the windshield, for the first time--are crafted out of polycarbonate. Of course, these weight-saving measures result in lowering the car's center of gravity and ensuring a more balanced weight distribution and more predictable handling.

The GT3 R also takes advantage of the aerodynamic designs of the GT3 RS road car. The wheel arch air vents on the front fairings increase downforce at the front axle, for instance, which is then balanced at the rear by the 2m-wide rear wing. The GT3 R, however, ditched the side radiators of the GT3 RS in favor of the centrally positioned radiator of the 911 RSR, improving not only the car's center of gravity but also protecting said component from collision damage.

Safety features of the GT3 R include the 120-liter FT3 safety fuel cell (now been fitted with a fuel cut-off safety valve), removable doors and side mirrors, a new racing bucket seat that supposedly offers even better protection, and a larger roof escape hatch.

Powering the 310mm rear wheels is a normally aspirated 500hp 4.0-liter flat-six engine through a paddle shift-equipped sequential six-speed constant-mesh gearbox. Despite the prodigious output, the mill is reportedly fuel efficient, thanks to the use of direct injection, which operates at pressures of up to 200bar, and variable valve timing technology.

Providing the stopping power for the GT3 R are six-piston aluminum monobloc racing brake calipers and 380mm ventilated and grooved steel brake discs up front, and four-piston calipers and 372mm discs for the rear.

The Porsche 911 GT3 R can now be ordered for 429,000 euros (nearly P22 million), with delivery of the units starting from December 2015.
