The Porsche 911 GT3 Cup racer has been revised to make it “suitable for an even wider range of endurance racing”, according to Porsche.
Chief among the changes are the addition of a 100-litre FT3 safety fuel tank, which is filled via an opening in the front bonnet.
The new car also gets 18-inch lightweight alloy wheels with Michelin race tyres and adjustable blade-type anti-roll bars, which are adjustable in seven positions “allowing an extremely precise set-up for each race track”.
The racer features the same 444bhp 3.8-litre flat-six engine as the Porsche GT3 RS. On the Porsche Mobil 1 Supercup models, ceramic composite brakes (optional on the road car) are standard.
Compared with the road car, however, the Cup racer has a weight reduction of 170kgs to 1200kgs and bigger front and rear spoilers for increased down-force on track.
The Porsche 911 GT3 Cup, which is based on the 911 GT3 RS road car, is the most popular customer race car in the world, with over 2200 units sold.
Deliveries of the updated car start from September and “will be run in this specification for the 2012 and 2013 race seasons”.
Prices start from £141,800 plus VAT.
