A new GT3 Cup S, based on the road-going GT3 RS sportscar, has been launched exclusively for racing purposes.

The Weissach-developed and built vehicle will race in international champion-ships which run in accordance with FIA GT3 regulations.

324kW flat-six power

The 3.6-litre boxer engine is largely identical to the power unit used in the Porsche Mobil1 Supercup and the international Carrera Cup championships.

Power output is 324 kW at 8,000 r/min. Maximum torque is up by ten Nm to 430Nm at 7,250 r/min. Revised ECU engine mapping and a new exhaust system are primary sources of the newfangled power, and with the cup weighing only 1170kg, performance should be epic.

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.

Massive rear-wing

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 massive 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 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.
