2008 Porsche 911 GT2 review - the true supercar


           The Porsche revealed its most powerful production 911 ever on September 11, 2007 at the Frankfurt Motor Show. Based on the current 911 Turbo, the 911 GT2 will easily ascend to lead the impressive Porsche family of vehicles.The power unit of the new 911 GT2 is based on the six-cylinder boxer engine of the 911 Turbo, with air supply driven by two exhaust gas turbochargers featuring variable turbine geometry (VTG). The 3.6-litre boxer engine achieves a maximum output of 530 (SAE) horsepower, an increase of 50 horsepower from the previous 911 GT2. The power increase is provided by two turbochargers with a larger compressor wheel and a flow-optimized turbine housing raising turbocharger pressure to an even higher level.
            The steering is the GT2's trump card. As the speed increases, the helm transforms from tame to tango. While there's nothing particularly wrong with the Turbo's tiller, everything's right with the GT2's steering. Sublime is just a word. If you can't feel exactly what the wheels are doing, check your arms for needle marks. Credit weight savings from the GT2's rear wheel drive configuration.
          The new 911 GT2's expansion intake manifold, which uses oscillating air in the intake during the cooler expansion phase, keeps the temperature of the fuel/air mixture even lower than in the 911 Turbo. This results in a significant increase in all-round efficiency, with fuel consumption down by up to 15 percent under full load despite the increase in engine output. This is a genuine innovation for turbocharged power units.
