3 . 031 copies of its successful model are available from Porsche 911 GT3 Cup built so far. But none of them had a four-liter engine on board. In 2010, the Zuffenhauser last switched from the old 3.6 liter boxer to a 3.8 liter unit. Now there is another 200 cubic centimeters more displacement for the 2017 model year.
New Porsche 911 GT3 Cup with 25 hp more
The intervention is also reflected in the performance. Instead of 460 hp in the old engine, the pilot will in future have 485 hp on the rear axle. In addition to the performance, according to Porsche, the efficiency and durability of the naturally aspirated engine have also been improved. According to the manufacturer, maintenance costs could also be reduced.
For the first time, a valve train with rigidly mounted rocker arms and a central oil feed are used. An integrated oil centrifuge is used for optimum oil defoaming in the engine. In addition, a crankshaft with significantly increased rigidity is installed.
The aerodynamics of the cup racer have also been refined again. New aprons on the front and rear should provide more traction. The 184 centimeter wide rear wing, on the other hand, has been adopted unchanged from the previous model. Thanks to a weight-saving and highly rigid aluminum-steel composite construction, the new 911 GT3 Cup weighs just 1,200 kilograms ready to race.
The dimensions of the wheels also remain unchanged: One-piece 18-inch racing rims with central locking are used all around the front axle with 270 millimeter wide Michelin racing slicks, on the rear axle with a 310 millimeter wide tread.
Porsche improves safety equipment
On the other hand, driver safety has been improved once again. They are protected by a massive safety cage and by a racing bucket seat that is particularly strong in the head and shoulder area. The enlarged escape hatch in the roof according to the latest FIA standard facilitates first aid and rescue in the event of an accident.
The Cup 911 is built in the main factory in Zuffenhausen. In the motorsport center in Weissach there is then a basic set-up for the racetrack. Before being delivered to the customer, each model is thoroughly tested by a professional racing driver. The new model can now be ordered at a price of 189,900 euros (plus taxes).
The new 911 GT3 Cup will initially be used exclusively in the 2017 racing seasonPorsche Supercup, which is held as part of the Formula 1 races, in the Porsche Carrera Cup Germany and in North America. From 2018 the vehicle will also be available for the other brand cups. Porsche is organizing a total of 20 of these racing series for customer teams worldwide, in which only the 911 GT3 Cup is used.
