Porsche 911 GT3 RS (2007)
Porsche 911 GT3 RS
The new Porsche 911 GT3 RS offers all the performance and undiluted driving experience of a genuine racing car, but nevertheless fulfils all requirements and standards for a sports car homologated for the road.
A particular highlight of the new RS compared with 911 GT3 is extra body width of 44 millimetres or 1.73" at the rear. Beneath this muscular rear end lurks the car's even wider track not only improving roll stability, but also enhancing the lateral acceleration of this thoroughbred two-seater Coupé. And despite its unique body, the Porsche 911 GT3 RS is 20 kilos or 44 lb lighter than the 911 GT3, weighing only 1375 kg kilos or 3032 lb in road trim with a full tank.
This reduction in weight is achieved, inter alia, by the use of an adjustable rear wing made of carbon, an extra-light plastic rear window, and the use of lightweight bucket seats. The car's power-to-weight ratio, as a result, is just 4.5 kg/kW.
Like the 911 GT3, the 911 GT3 RS is powered by Porsche's very fast-revving 3.6-litre developing maximum output of 305 kW (415 bhp) at 7600 rpm. Maximum engine speed is 8400 rpm.
Benefiting from its six-speed gearbox with a single-mass flywheel and close gear increments, as well as a reduction in weight by another 20 kilos or 44 lb compared with the GT3, the engine revs up even more spontaneously, with the Porsche 911 GT3 RS accelerating to 100 km/h in a mere 4.2 seconds, one-tenth of a second faster than the 911 GT3. This dynamic acceleration then continues in just 13.3 seconds overall to 200 km/h or 124 mph. And top speed, finally, is 310 km/h or 192 mph.
Inspired by motorsport
Looking at the homologation rules for major Gran Tourismo championships as the car's major domain, we see that the Porsche 911 GT3 RS in road trim comes with technical solutions also to be found in future on the racing version. Apart from carbon-fibre components on the bodyshell, these include the complete wheel support subframe as well as the split track control arms on the rear axle.
The interior also reflects the car's sporting ambitions, two lightweight composite carbon-fibre bucket seats as well as the Clubsport package naturally coming as standard. The Clubsport package is made up of a bolted rollcage and a preliminary kit for fitting the main battery switch.
Further features, finally, are a six-point seat belt for the driver as well as a fire extinguisher.
