Porsche GT3 RSR – 2008
Porsche GT3 RSR
Importantes mejoras para el modelo 2008
With extensive modifications the Porsche GT3 RSR goes into new model year. The strongest racing car on basis Porsche 911, which could celebrate class victories with the 24-Stunden-Rennen in Le Mans and Spa as well as the total victory in the past season among other things at the 24 hours of Nuerburgring, goes in the class GT2 when international long-distance running to the start. Clearest registration number of the new GT3 RSR is the aerodynamically strongly improved front portion. Most innovations are however under the weight-optimized body.
Beside the well visible auxiliary spoilers at the front apron, the Flicks in such a way specified, an optimized air circulation ensures also newly arranged lateral air discharge openings for more drift with air resistance reduced at the same time. The tail range including tail wing was taken over by the predecessor model. Extensive changes at the chassis kinetics provide for clearly increased mechanical Grip. Also the adjustment possibilities at the chassis were extended.
The 3,8-Liter-Boxermotor of the GT3 RSR remained unchanged up to easy detail improvements. It carries 465 HP out (342 KW) when 8.000 revolutions per minute and develops a maximum torque of 430 Nm when 7.250 revolutions per minute. The speed limiter of the efficient six-cylinder begins with 9.400 crankshaft revolutions.
A quantity of know-how from that sport prototypes R-S Spyder is in the completely new transmission of the GT3 RSR. That by Porsche engineers developed of sequenzielle six-course impulses is substantially easier than the switching box blocked in the predecessor and exhibits a clearly reduced internal friction. The flatter angle to the half axles permits a larger clearance to the teams during the chassis attitude.
Beside the GT3 Cup and the GT3 Cup S the GT3 RSR is the third running vehicle on basis Porsche 911, which is offered by Porsche engine haven. That, apart from exclusive sport prototypes R-S Spyder, fastest and strongest long-distance racers out white oh is produced in an edition by approximately 35 vehicles and delivered immediately to the customer teams in all world. The price for the GT3 RSR amounts to 349,800 euro plus the country-specific value added tax.
