Porsche 911 GT3 RSR

Porsche had launched the GT3 RSR, the most powerful race car based on the Porsche 911. The most distinguishing feature of the new GT3 RSR is the front end which received major improvements to the aerodynamics. Most of the innovations are hidden under the modified body. The model features a 3.8-liter boxer engine and delivers 456 horsepower at 8.000 rpm and 430 Nm of torque at 7.250 rpm. The power is being sent to the wheels through a six-speed transmission developed by Porsche engineers. The body is made of steel and a lot of the features were optimized. The brake system has a balance bar control. The electrical system includes Motec display with integrated data recording, adjustable traction control and batteries: 12 volt, 50 Ah and a 140 Ah alternator. It also has three-piece BBS alloy wheels at the front and at the rear. The model weights around 1.225 kg complying with A.C.O. regulations and 1.200 kg complying with FIA regulations.

The Porsche GT3 RSR launches into the new model year with extensive modifications. The most powerful race car based on the Porsche 911, which last year scored wins at the 24 hour races of Le Mans and Spa as well as overall victory at the Nuerburgring 24 hours, competes in the GT2 class at international long distance races. The most distinguishing feature of the new GT3 RSR is the front end which received major improvements to the aerodynamics. The majority of innovations however are hidden under the weight-optimised body.

Aside from the easily recognisable additional spoilers on the front apron, so-called flicks, an optimised air ducting with newly-designed side air outlets generates more downforce and reduces drag. The rear end including the rear wing was taken over from the predecessor. Extensive changes to the suspension cinematics increase mechanical grip considerably. The range of possible suspension set-ups was broadened.

The 3.8-litre boxer engine of the GT3 RSR remains unchanged apart from slight improvements to details. It delivers 465 hp (342 kW) at 8,000 revs per minute and delivers a maximum torque of 430 Nm at 7,250 revs. The rev limiter of the efficient six-cylinder kicks in at 9,400 rpm.

Much of the know-how in the GT3 RSR`s totally new gearbox has come from the RS Spyder sports prototype. The sequential six-speed unit, developed by Porsche engineers, is considerably lighter than its predecessor. Internal friction was substantially reduced. The flat angle of the drive shafts allows teams a wider range of suspension set-ups.

Aside from the GT3 Cup and the GT3 Cup S, the GT3 RSR is the third race car based on the Porsche 911 offered by Porsche Motorsport. Thirty-five units of the fastest and most powerful long distance racer made in Weissach, apart from the exclusive RS Spyder sports prototype, are now being produced and delivered to customer teams around the globe. The price of the GT3 RSR is 349,800 Euro plus VAT.
