Porsche Reveals 440bhp 911 for GT3
Using tried-and-tested parts from its GT2 and Cup contenders, Porsche has produced a potent GT3 car that will surely be a front-runner in this year’s championships.
The new GT3 Cup S is based on the road-going GT3 RS sports car but features a 3.6-litre boxer engine, identical to the power unit used in the Porsche Mobil1 Supercup and the international Carrera Cup, tuned to produce an additional 20bhp. Maximum torque is up by 10Nm to 430 at 7250rpm.
The bodywork is from the standard car, its extra width over the Cup machines allowing 10.5” front, and 12” rear, wheels - the wide bodywork flared yet further. An adjustable front-splitter generates more downforce at the front axle, while the rear wing is wider and positioned higher than the Cup version, providing more downforce at the back.
Several suspension components for the GT3 Cup S have been taken from the more powerful GT3 RSR, and its braking system has been upgraded with 5mm larger diameter discs at the rear (to 355mm).
The new GT3 Cup S costs EURO 250,000 (plus national VAT) and is scheduled for delivery to customer teams from April.
As an option, Porsche offers a kit to upgrade the 2007 Cup models to GT3 Cup S standard.
