Porsche 911 GT3 RSR
The GT3 RSR, one of Porsche's three production racing 911s, have been upgraded for the new model year with numerous improvements intended to guarantee that it will continue the GT2 series successfully. The external improvements involved considerable alterations to the bodywork to guarantee added aerodynamics and front and rear downforce. These enhancements consist of fresh air outtake vents to accommodate an air-conditioning system option and more adaptability to the wing at the rear to improve handling.
The brake system, which has been 'weight optimized', is part of the improvement, as well as the installation of much lighter wiring harness in contrast to the preceding version. More improvements were done to the engine, with its 6-cylinder Porsche boxer receiving a displacement upgrade from 3.8 to 4.0-liter.
The latest RSR can now generate 450 hp (to last year's model of 465hp) and 430Nm of torque, thanks to a size reduction of its air restrictors for this year's season. Although the power may be lower, it is claimed by Porsche that the current model is easier to handle due to higher power yield at lower rpms throughout the range and a superior torque curve. On the interior the RSR received new display equipment that informs the driver the best time to change gears for optimum performance, besides this however the interior has been stripped to the level of a regular 911 and is equipped with the same list of race-specific buttons. The cost for the RSR is 380,000 Euros (around $500,000) about $300,000 above the price of a 911 GT2.
