Porsche 911 GT2: the lowdown

Earlier today the web was abuzz with leaked pictures of Porsche’s hottest car of the year. An American brochure was doing the rounds with all the juicy details of the hardcore GT2 revealed.

Porsche responded to the leak and released the first official details and pictures weeks early, revealed here for the first time. Read on for comprehensive coverage of Porsche’s ‘widow-maker’.

What are the stats?

The headline grabbing figures are 0-60 in 3.6 seconds, 100 in 7.4 and a top speed of 204mph. That betters the Turbo by a few tenths on both counts and 11mph at the top end.

How is the Porsche 911 GT2 so fast without four-wheel drive?

Weight, or rather lack of it. At 1440kg it is 145kg less than the Turbo, and only 45kg more than the lightweight GT3. As well as the lack of a front propshaft, a glass-reinforced plastic engine cover, titanium exhaust system and standard Porsche Carbon Composite Brakes (PCCB) complete the diet. The brakes alone are 50 percent lighter than equally-sized steel discs.

But what about the power?

Headline figures are 530bhp at 6500rpm (50 ponies), while the 505lb ft is 45lb ft stronger, and available from 2200-4500rpm. Enough said really.

So it’s quick then?

Oh yes, and helped by Porsche’s new launch control system. Hold down the clutch and accelerator, wait until the twin turbos reach 13psi of boost, step off the clutch smartly and the ECU will sort out the rest. The engine management system makes sure there’s no turbo-lag, no wheelspin, just relentless acceleration.

How does Porsche get all this power?

With a tried and tested 3.6-litre boxer engine and a few interesting tweaks. There’s VTG (Variable Turbine Geometry) as first seen on the Turbo. The turbines move to eliminate turbo lag at low revs, whilst adapting again to provide big power at high revs.

This is all helped by the 'ram effect' created by the air intakes in the new fixed rear wing, which has an integrated lip spoiler. Combined with the full bodykit, including a GT3-style air outlet ahead of the bonnet, it creates positive downforce front and rear.

Is the GT2 as hardcore as ever?

Not quite, for this Porsche gets traction control and stability control for the first time. Luckily, with Porsche Stability Management (PSM) you can turn off both, and once they’re off, they’re off until you turn them back on.

However, the car also comes with PASM (Porsche Active Suspension Management) so you can switch between ‘Normal’ for everyday driving, and ‘Sport’ for some track action.

Can I still tweak the suspension?

You can, but we hope you know what you’re doing. You can change the ride height, camber, toe angle and anti-roll bar. Good luck with that.

Above is the leaked American brochure, by the way. It rapidly worked its way around the world on chat forums and caused all sorts of palpitations over in Zuffenhausen...

Anything else?

Funny you should ask, but Porsche is claiming major changes to the turbo technology used. With the expansion intake manifold, the Stuttgart manufacturer believes it has created a new technology that is radically different to the existing induction principle for turbocharged engines.

Usually air is compressed to force it into the ignition chamber, but doing so heats it up resulting in poorer ignition. Now, with longer, thinner distribution pipes, and shorter intake manifold, air is in the expanding phase as it reaches the combustion chamber and so it's cooler. Or so Porsche claims.

And this doesn’t mean less air enters the engine. Porsche has upped the boost pressure and uprated the intercoolers to compensate. Ultimately, Porsche says, the driver gets more power, better ignition and a more efficient engine.

Anything new inside?

The 911 GT2 is pretty much the same as the GT3 inside, apart from assorted logos. The Chrono Package Plus is optional and lets you time your laps, and there is a new shift light indicator integrated into the rev counter. But this is no sop to economy, but rather designed to make sure you have optimum acceleration.

Porsche has confirmed the price and on sale date: £131,070 and November 2007. Luckily that price includes a Porsche driving course, so perhaps the GT2 will no longer have the nickname 'the widow-maker'.

Mmm, on the contrary I love the rear bumper treatment, those slatted vents remind one of the jet outlets on a futuristic stealth aircraft.

God. What I'd do to drive one of these things for a weekend and a bit...

[Imhotep Evil]

Bah, nothing new.

Such rear wing designs appeared on F1 cars in the 1994 season after the ban of the active ride cars.

But this a road vehicle, not an F1 vehicle. Your particular sentence has no relevance to this discussion.

Furthermore, I don't see any where in that article where Porsche boasted about the rear spoiler design being unique or new to the automotive world.

I was joking a little bit. Just forgot the smilies.

OK, no hard feeling.

From GCZ: New Porsche 911 GT2 Officially Revealed with 530 Horsepower

It has been a week of brochure leaks, starting with the - ONLY REGISTERED AND ACTIVATED USERS CAN SEE ALL LINKS - CLICK HERE TO REGISTER followed by the - ONLY REGISTERED AND ACTIVATED USERS CAN SEE ALL LINKS - CLICK HERE TO REGISTER and then - ONLY REGISTERED AND ACTIVATED USERS CAN SEE ALL LINKS - CLICK HERE TO REGISTER over the weekend. Whether it is second phase of their media push or simply damage control, Porsche has released their teaser press materials announcing the GT2 public debut in Frankfurt this September.
The European market launch starts in November of this year at a base price €159,100 (Excl. 19% VAT) and then making its North American debut at Detroit 2008 with a MSRP of $191,700.
Using the same engine as the Turbo model, power is pumped up 50hp to 530hp using bigger turbos and a “flow-optimized turbine housing” which increases boost pressure. Also, a new “expansion-type” intake manifold which cools the air/fuel mixture more than the “standard Turbo” creates more efficient combustion resulting in fuel consumption down by 15% despite the power increase.
Another new feature for the first time is a titanium muffler and tailpipes as standard equipment. Also standard are the carbon/ceramic PCCB brakes discs as well as the electronically controlled Porsche Active Suspension Management (PASM).

PRESS RELEASE
High-Performance Sports Car with Low Fuel Consumption
Presenting the new 911 GT2 at the Frankfurt Motor Show, Dr. Ing. h.c. F. Porsche AG, Stuttgart, is proudly launching the most powerful 911 so far homologated for road use. Through its striking design with large air intakes at the front and the rear wing so characteristic of this very special model, the new 911 GT2 expresses the power and performance potential of the fastest-ever 911 right from the start even at a standstill. Available exclusively with rear-wheel drive and a manual six-speed gearbox, this high-performance athlete accelerates to 100 km/h in just 3.7 seconds and reaches a top speed of 329 km/h (204 mph) on average fuel consumption of just 12.5 litres/100 km (equal to 22.6 mpg imp) in the New European Driving Cycle (NEDC), thus offering a level of fuel economy regarded as quite impossible in this performance class just a few years ago.

The power unit of the new 911 GT2 is based on the six-cylinder boxer engine of the 911 Turbo, with air supply by two exhaust gas turbochargers featuring variable turbine geometry (VTG). The 3.6-litre boxer engine achieves its maximum output of 530 bhp (390 kW) at 6500 rpm, with maximum torque of 680 Newton-metres maintained consistently between 2,200 and 4,500 rpm. With its unladen weight of 1,440 kg or 3,175 lb, finally, the 911 GT2 offers a power-to-weight ratio of just 2.72 kg/6.00 lb per horsepower.

The increase in engine power by 50 bhp over the ”regular“ power unit is provided in the new 911 GT2 by two turbochargers with a larger compressor wheel and a flow-optimised turbine housing raising turbocharger pressure to an even higher level. And for the first time Porsche’s engineers have combined the turbocharged engine with an expansion-type intake manifold – a genuine revolution on turbocharged power units.

The expansion intake manifold uses the principle of oscillating air in the intake manifold during the cooler expansion phase, keeping the temperature of the fuel/air mixture lower than in the 911 Turbo. This, in turn, means a significant increase in all-round efficiency, with fuel consumption down by up to 15 per cent under full load despite the increase in engine output.

The 911 GT2 offers new achievements also in terms of emission management and control: This is the first Porsche homologated for the road to feature a rear silencer and tailpipes made of titanium as standard equipment. This expensive material reduces weight by approximately 50 per cent versus a comparable component made of stainless steel to just 9 kg.

The new 911 GT2 comes as standard with PCCB brakes featuring brake discs made of a composite carbon fibre/ceramic compound ensuring maximum stopping power maintained with an extremely high level of consistency. A further advantage is that PCCB brakes reduce the weight of the unsprung masses versus comparable grey cast-iron discs by approximately 20 kg or 44 lb.

Yet another feature fitted as standard is the electronically controlled PASM Porsche Active Suspension Management. (PASM). The GT2 comes on 19-inch light-alloy wheels running at the front on 235/35 ZR 19, at the rear on 325/30 ZR 19 sports tyres.

The new 911 GT2 will be at the dealership in November 2007. The base price of the car in Germany is Euro 159,100.-, the market price including 19 per cent value-added tax Euro 189,496.-.

As long as tail doesn't swing you off a mountain road and ending up swimming with sharks in the ocean. It takes a very experienced Porsche driver, skilled and sensible man to play around with this car. RWD, rear located engine and 530hp. A combination resulting in death if driven by someone over confident. The GT3 is probably adequate for most enthusiasts.
