The 2009 Porsche GT3 RSR

2009 Porsche GT3 RSR

Porsche unleashed its latest model of its GT2-class race car, the 2009 Porsche GT3 RSR. With a new louvered hood as it's visual difference. The car's radiator ductwork has been redesigned for the racer's preferred air conditioning system. They also included a developed supply system for a consistently adaptable blink rate of its front lights. Which makes it easy to identify when car pits during night time. The GT3 is also equipped with a new air jack and a much easier accessed oil filler which has been relocated.

Now that comprises the visual part of the GT3. Lets go to a much better topic, the POWER. The 2009 Porsche GT3 RSR is equipped with a 450 horsepower at 7,800 RPM (compared to last year producing 465 horsepower at 8,000 RPM) with a displacement for the rear-mounted 6-cylinder from 3.8 up to 4.0 liters. Same with last year's GT, GT3 is also powered by a 317 lb-ft of torque at 7,250 RPM. Porsche said that the new GT3's torque curve is well-optimized than the past model for better driving. The 2009 Porsche GT3 RSR will cost you at around $493,392.
