FOR 2004 the 911 GT2 has been revised, creating the most powerful road-going version of the 911 yet, with a maximum output of 483 bhp (355 kW 21 bhp (15 kW) more than the previous model.

Increased performance has been achieved by development of the electronic engine management system. Maximum torque has risen by 20Nm to 640Nm, available between 3,500rpm and 4,500rpm and, with a power-to-weight ratio of 4.06kgs per kW, the rear wheel drive GT2 can accelerate from 0 to 100km/h in just four seconds and 0 to 200km/h in 12.5 seconds. Top speed is 319km/h (196 mph), making the new car 4km/h faster than its predecessor.

In developing this powerful turbo-charged model, extreme sports performance was a clear priority. In addition to the power output increase, front and rear suspension have been optimised with modified springs/shock absorbers, and the brake system has been revised, with even more sensitive four-channel ABS for effective anti-lock braking.

Exhaust emissions compare with the 911 Turbo and easily comply with the stringent D4 regulations, equivalent to the Euro 4 standard test limits, which will become mandatory from January 2005. The car also satisfies the US LEV standard.

The advanced aerodynamics of the GT2 are further enhanced for 2004 by a new, distinctive carbon-fibre rear spoiler, which weighs 2.8kg less than its predecessor. The new rear wing is available on request and comes as standard on the Clubsport version with carbon-fibre door mirror housings and radiator ducts.

The 911 GT2 is fitted with new GT3-style wheels, measuring 8.5ins wide with 235/40R 18 tyres at the front and 12ins with 315/30R 18 tyres at the rear. Porsche Ceramic Composite Brakes (PCCB) are standard, with ceramic brake disks weighing 50 per cent less than comparative metal disks, reducing the car's unsprung weight by 18kgs. Porsche Ceramic Composite Brakes are also available as an optional extra on the 911 Turbo, 911 GT3 and Carrera 4S.
