Porsche has unveiled the latest iteration of its GT2-class racing car, the GT3 RSR. Visually, the biggest difference for '09 is up front, where a substantially louvered hood now resides. It's there because the car's radiator ductwork has been redesigned so as to accommodate the racer's optional A/C system. Other changes are hidden, but no less important. Aero tweaks include a rear wing angle that's more adjustable than on last year's car. The brakes and wiring harness contribute to lighter weight, and inside the pilot gets a new multifunction display. There's also a revised supply system that allows for an infinitely adjustable blink rate for the front lights. That makes for easy nighttime identification when the car pits. The oil filler has been relocated for easier access, and the GT3 RSR is equipped with a new air jack, as well.

That's all well and good, but what about the power? Displacement for the rear-mounted six-cylinder jumps from 3.8 to 4.0 liters, and it now pumps out 450 horsepower at 7,800 rpm. (Last year it produced 465 hp @ 8,000 rpm) Torque is rated at 317 lb-ft (430 Nm) at 7,250 rpm - same as last year. The rev limiter kicks in at 9K (it was 9,400 rpm in '08), and Porsche says that the new car's torque curve is better-optimized than the outgoing car's. The new car ought to become a common sight in the Le Mans series on both sides of the Atlantic, as Porsche resumes its annual battle with Ferrari in sports car racing. Want one? Give Porsche €380,000 (plus the appropriate VAT) and you're good to go. Tech specs are pasted after the jump.
