2008 Porsche 911 GT3 Cup S

To a large extent, the 3.6-litre boxer engine is identical to the power unit used in the Porsche Mobil1 Supercup and the international Carrera Cup championships. Power output has increased by 20 horsepower to now 440 hp (324 kW) at 8,000 rpm. Maximum torque is up by ten Nm to 430 at 7,250 revs per minute. The power increase results from optimised engine electronics and a modified exhaust system.

In contrast to the GT3 Cup, the body of the Cup S is not based on the road-going GT3 but on the GT3 RS. In the wider wheel arches, considerably larger wheels can now be mounted. At the front, the rims measure 10.5 inches in width with 12 inch wheels fitted at the rear. The front section and flares are significantly different to the GT3 Cup components. An adjustable front-splitter generates more downforce at the front axle. The rear-wing is wider and positioned higher than the Cup version and provides more downforce at the rear axle.

Several suspension components for the GT3 Cup S have been taken from the more powerful GT3 RSR which races in the GT2 class at international long-distance championships. The braking system of the GT3 Cup S was adjusted to the increased power compared to the GT3 Cup. At the rear the diameter of the brake discs has grown by five millimetres to now measure 355mm.

The new GT3 Cup S costs 250,000 Euro plus national VAT and is scheduled for delivery to customer teams from April. Additionally, Porsche offers a kit to upgrade the 2007 Cup models to the GT3 Cup S standard.
