As expected, Porsche unveiled today at the 2013 Geneva Motor Show the all-new 911 (991) GT3. For those who don’t know, this is the fifth generation of the 911 GT3 and honestly to tell you the numbers are quite impressive. The 991 GT3 is powered by a 3.8-liter boxer engine delivering 475 hp (350 kW) @ 8,250 rpm bolted to a Porsche dual-clutch transmission (PDK) which delivers the power to the rear wheels.
The six-cylinder engine is based on the same engine as the 911 Carrera S, but the two cars share only few common parts. According to the press release, the 991 GT3 features specially developed crankshaft and valve gear, Porsche designed titanium connecting rods and forged pistons.
Porsche dual-clutch transmission was also specially developed. With a power to weight ratio of 3.0 kg/hp, the 991 GT3 is able to hit 100 km/h (62 mph) in just 3.5 seconds and has a top speed of 315 km/h or almost 196 mph. Moreover, the Porsche 991 GT3 is able to hit 200 km/h (124 mph) from a standstill in just 12 seconds.
The lap time on the Nürburgring Nordschleife, which the new 911 GT3 manages in under 7:30 minutes, is even more impressive. Comparing it with the Porsche 991 Carrera S, the new GT3 is 44 millimeters wider in the area of the rear axle and features a fixed rear wing.
This makes a decisive contribution to the exemplary aerodynamics of the new 911 GT3, which combines low air resistance with even more power. For those who want a 991 GT3, this vehicle will be launched on the market from August 2013 and will cost in Germany 137,303 Euro including VAT and national specifications.
When the automotive heavens decided to make cars more aerodynamic, they thought of nothing else but the Porsche 911 GT3. Compared to its predecessor the 911 Carrera, the GT3 features improved air supply to the radiator brought about by the integration of the new front lights and larger holes. Another noticeably distinct upgrade in the Porsche 911 GT3 is the laterally raised spoiler contour, giving it a look of continuous horizontal middle element. The GT3’s wheel arches are also characterized by lateral continuations aided by a scoop-shaped, drawn-out lip aimed to further boost the front axle-propelled downforce.
Porsche 911 GT3 has another distinct identifying feature in its rear with its boot lid with fixed wing which also has additional air outlet. This new rear boot lid is composed of composite materials consisting of glass and carbon fibre. This is further enhanced with the addition of other integral components like wing supports, the large ram-air intake for the air supply of the engine, and the spoiler lip. The rear wing is mounted on the supports, allowing it to be individually adjusted for use on the circuit racetrack. The rear bodywork also features exhaust vents, two on the side and one under the rear boot lid.
Consistent with its theme of being the supreme in aerodynamics, the Porsche 911 GT3’s front and rear design result in establishing just the right balance among the three main requirements of low drag: dependable cooling of drive and the brakes, and sportive downforce at higher speeds. The downforce at the front and rear axle is ably supported by the front spoiler and rear wings while the additional diffuser effect brought about by the engine area’s rising contour is held together by the underbody panel, thus allowing the GT3 to maintain stability when running at a speed that mortals among cars are not capable of.
True to its character and legacy, the interior of the 911 GT3 is sporty as it is opulent. The electronically-controlled lumbar support and height adjustment, the covered back seat shells, the raised side supports, and mechanical length adjustment not only provide the car’s occupants comfort and safety, but these are fitted with only the finest materials sourced by a company of Porsche’s stature to make riding the Porsche 911 GT3 a luxuriously speedy experience.
