Here in Frankfurt, Porsche downplayed the release of its new, batshit-mad 911 — the GT2. Instead, boss Wendelin Wiedeking spent his keynote vehemently defending Porsche's environmental record in the face of Greenpeace allegations of extreme piggishness. He also asserted Ferdinand Porsche built a gas-electric hybrid in the early part of the century. Take that, Japanese! But for us the show was the rollout of the is the fastest and most powerful Porsche 911 ever homologated. The GT2 — as we've mentioned before — is the first 911 ever to hit 200+ mph from the factory, via a 3.6-liter flat six twin turbo producing 530 hp at 6,500 rpm, and maximum torque of 501 lb-ft from 2,200 - 4,500 rpm. Acceleration to 62 mph comes in just 3.7 seconds and the new top-dog 911 can hit 204. Bruce 1, Greens: DNF.
The New Porsche 911 GT2
The 911 GT2 is the fastest and most powerful Porsche 911 homologated for the road to ever see the light of day. Its 3.6-litre horizontally-opposed six-cylinder power unit with biturbo technology develops maximum output of 530 bhp (390 kW) at a speed of 6,500 rpm. Maxi¬mum torque of 680 Newton-metres or 501 lb-ft, in turn, is maintained consistently over a speed range from 2,200 - 4,500 rpm. Acceleration to 100 km/h comes in just 3.7 seconds and the new top sports model within the 911 Series reaches a staggering top speed of 329 km/h or 204 mph.
Full of character, full of efficiency
The low-slung spoiler lip at the front and the rear wing so characteristic of this very special model give the 911 GT2 remarkable down force both front and rear, while at the same time maintaining the silhouette so characteristic of this top model. Low weight of 1,440 kg or 3,175 lb, rear-wheel drive and a superior drag coefficient of Cd = 0.32 ensure not only exceptional sportiness and performance, but also a supreme standard of all-round efficiency. As a result, the 911 GT2 consumes just 12.5 litres/100 km of premium plus fuel in the composite EU test (equal to 22.6 mpg imp), thus offering a standard of fuel economy exceptionally good for a car of this kind.
A world-first achievement: the expansion intake manifold
Using the oscillating air during the cooler expansion phase is a genuine revolution in turbo¬charged engine technology. So benefiting from a brand-new, innovative expansion-type intake system with its own special geometry and an exhaust gas turbocharger with variable turbine geometry operating at a maximum pressure of 1.4 bar, new 911 GT2 offers an extra 50 bhp over the already very powerful 911 Turbo.
Chassis with PASM and ceramic brake system
Compared with the 911 Carrera, the new 911 GT2 has been lowered by approx 25 mm or 1.00", with the chassis and suspension geared specifically to the needs of this very dynamic car. And as one would rightly expect of a Porsche sports car, the GT2 comes with unusually powerful and effective brakes, PCCB Porsche Ceramic Composite Brakes featuring brake discs measuring 380 millimetres or 14.96" in diameter at the front and 350-millimetre (13.78") brake discs at the rear fitted as standard on this top-of-the-range sports model.
Three-stage PSM and Launch Assistant
Featured for the first time in the 911 GT2, PSM Porsche Stability Management can be deac¬tivated in two stages, with the ABS anti-lock brake system always remaining active: The driver is able to deactivate lateral and longitudinal dynamic control in a successive process, thus gearing the car's driving behaviour to his individual demands and requirements. The new Launch Assistant, in turn, enables the driver, via the engine control unit, to accelerate with optimum power and performance from a standstill, TC Traction Control ensuring opti¬mum longitudinal dynamics in the acceleration process.
Titanium exhaust gas system and folding sports bucket seats
The new 911 GT2 is the first Porsche homologated for road use to be fitted as standard with an exhaust system featuring a titanium rear-end silencer and titanium tailpipes. Compared with a comparable silencer made of stainless steel, titanium reduces the weight of the entire system by approximately 50 per cent.
Another new feature in the 911 GT2 is the sports bucket seats likewise fitted as standard. And a further advantage in this case is that the backrests fold individually to any desired position, maintaining optimum lateral stability at all times.

Top Performance in the 911
The 911 GT2 is the new top performer in the 911 model series. Through its striking design with extra-large air intake scoops at the front and the characteristic rear wing, this fastest of all models in the 911 series clearly demonstrates its supreme performance right from the start, before even setting off. Indeed, these design and streamlining features so characte¬ristic of the 911 GT2 give the car an exemplary drag coefficient of Cd = 0.32, together with down¬force on both the front and rear axle.
Available only with a manual six-speed gearbox, the 911 GT2 supersports accelerates to 100 km/h in just 3.7 seconds and reaches a top speed of 329 km/h or 204 mph.
Two turbochargers for extra power
The power unit of the new 911 GT2 is based on the flat-six already featured in the 911 Turbo, with two exhaust gas turbochargers using variable turbine geometry (VTG) providing the requisite supply of air. Maximum output of 530 bhp (390 kW) from this 3.6-litre boxer engine comes at 6,500 rpm, peak torque is 680 Newton-metres (501 lb-ft) maintained consistently over a wide speed range between 2,200 and 4,500 rpm. And with the car's unladen weight being just 1,440 kg or 3,175 lb, the power-to-weight ratio is 2.72 kg or 6.00 lb per horsepower.
Innovative air supply
The extra power of the engine in the new 911 GT2 versus the 911 Turbo is provided by two exhaust gas turbochargers with an enlarged compressor wheel and the flow-optimised tur¬bine housing, both of which are laid out for even higher charge pressure.
A further point is that Porsche's engineers have for the first time combined the turbocharged power unit in the 911 GT2 with a so-called expansion-type intake manifold - a genuine revo¬lution in the concept of turbocharged power units. The principle applied in this case is to use the oscillating intake air during the cooler expansion phase to prepare the fuel/air mix¬ture, keeping the temperature of the fuel/air mixture lower than in the engine of the 911 Turbo. This ensures a significant increase in all-round efficiency - more power on less fuel, with fuel consumption dropping by up to 15 per cent under full load. As a result, average composite fuel consumption in the New European Driving Cycle (NEDC) of 12.5 litres/100 km or 22.6 mpg imp is exceptionally good for a car of this class - and thanks to its new exhaust system, the new 911 GT2 also outperforms the EU4 emission standard.
Extra-light exhaust system
The 911 GT2 offers new developments and highlights not only on the intake manifold, but also on the exhaust side: This is the first Porsche homologated for the road to feature a rear-¬end silencer and tailpipes made as standard of titanium, an extra-light but stable material. Weighing approximately 9 kilos, the silencer is roughly 50 per cent lighter than a comparable component made of stainless steel.
Setting off with the Launch Assistant
The new 911 GT2 is likewise the first production sports car from Porsche to feature a Launch Assistant enabling the driver to set off with optimum performance and ensuring simple hand¬ling at all times.
To activate the Launch Assistant, all the driver has to do is press down the throttle in full with the car at a standstill, the appropriate gear in mesh, and the clutch pedal pressed to the floor. Then the system will automatically set engine speed to exactly the right level, the driver's only task then being to take his foot off the clutch as quickly as possible in order to accelerate the car with maximum speed and power.
In this process PSM Porsche Stability Management prevents the car from "twitching", with the full power of the engine being transmitted smoothly to the road.
Rear-wheel drive on the 911 GT2 comes with an asymmetrical limited-slip differential main¬taining a locking factor of 28 per cent under power and 40 per cent in overrun.
Porsche's new supersports runs on 19-inch wheels combined with specially developed tyres measuring 235/35 at the front and 325/30 at the rear. Tyre pressure, finally, is supervised and maintained by sensors in the tyre pressure control system also featured as standard.
Specially set-up PASM damper system and upgraded PSM
The chassis and suspension of the new 911 GT2 is based on the chassis of the 911 GT3, while at the same time the entire set-up is approximately 25 millimetres or 1.00" lower and firmer than on the 911 Carrera.
PASM Porsche Active Suspension Management featured as standard on the new 911 GT2 has also been modified accordingly, with somewhat firmer and tauter damper action in the Normal mode, as opposed to an extra-firm and taut suspension in the Sports mode suited ideally for use on the race track.
The new 911 GT2 comes as standard with PCCB brakes featuring ceramic brake discs. The exceptional features of this brake system include in particular a very fast response, enormous stability against fading, superior safety reserves, and low weight.
Compared with grey-cast-iron brakes of the same size, PCCB reduces unsprung masses in the car by approximately 20 kg or 44 lb.
Yet another innovative feature developed by Porsche's engineers for the new 911 GT2 is PSM Porsche Stability Management specifically tailored to the new model: Giving the driver the option to deactivate various components, this special driving stability system meets the de¬mands of even the most sporting and dynamic motorist. To set up the system to his spe¬cific requirements, all the driver has to do is press two buttons in the front centre con¬sole: Pressing the SC OFF (SC: Stability Control) button, the driver deactivates lateral dynamic control. By additionally pressing the SC+TC OFF (TC: Traction Control) button, the driver also switches off longitudinal dynamic control, while the ABS brake system remains active at all times.
Innovative sports bucket seats
The high-performance concept of the 911 GT2 also includes sports bucket seats made of a very light combination of glass- and carbon-fibre-reinforced plastic (GFP/CFP) with a visible carbon surface, featured as standard on the new model. Incorporating a new type of manual adjustment, the sports bucket seats combine unusually good side stability with enhanced access to the area behind the front seats, thanks to the backrests tilting forward whenever required.
