Now, Porsche has unveiled the 2012MY 911 GT3 Cup. It is based on the 991 (997) GT3 RS, with the 3.8-liter flat-six engine producing an identical 450HP at 8,500 rpm.
However, it does get a race exhaust system that features a controlled catalytic converter to reduce CO2 emissions.
The new GT3 Cup has a larger 100-liter FT3 safety fuel tank, which is filled via an opening in the hood. According to Porsche, this change makes the car more suitable for a wider range of endurance racing.
The Porsche racer rides on 18-inch wheels shod in 25/64-18 front and 30/68-18 Michelin racing tires.
Both the front and rear anti-roll bars are adjustable in seven positions in order to achieve a customized set-up for each occasion.
In addition, the Porsche Mobil1 Supercar racers, which support the F1 championship, get exclusive use of the PCCB Porsche Ceramic Composite Brakes that, compared to the composite cast units used in other race versions of the 911, reduce overall weight by 20 kg.
Deliveries of the new 911 GT3 Cup will start in September and the car will be available in this specification for the 2012 and 2013 seasons. Pricing starts from €161,750 (~ US$228,700) not including local taxes.
