Porsche 911.2  Gt3 Cup 4.0 2021

Boasting a completely redeveloped drive, the Porsche 911 GT3 Cup tackled the 2017 season – initially exclusively in the Porsche Mobil 1 Supercup, in the Porsche Carrera Cup Deutschland as well as the Porsche GT3 Cup Challenge USA and the Porsche GT3 Cup Challenge Canada. From 2018, the latest version of the world’s most-produced GT race car will be campaigned in all of Porsche’s 24 one-make cup series around the world.

The rear of the new 911 GT3 Cup houses a four-litre, six-cylinder flat engine for powerful propulsion. Thanks to thoroughbred motorsport technology, the compact engine with direct fuel injection delivers a peak performance of 357 kW (485 hp). A range of innovative details also improves efficiency in addition to engine performance, ensuring even better durability of the naturally aspirated engine under racing conditions, as well as reducing maintenance costs. A valve drive with rigidly mounted rocker arms and a central oil feed is used for the very first time. An integrated oil centrifuge is used to optimise oil defoaming in the engine. A crankshaft with significantly increased rigidity has also been installed.

Better performance

A new front apron and a new rear end improve the downforce of the new 911 GT3 Cup compared to the predecessor model, thus enhancing traction and performance. The prominent 184-centimetre-wide rear wing has been retained from the predecessor model. One-piece 18-inch racing rims with a central locking mechanism are used – with 270-millimetre Michelin racing slicks on the front axle and a massive 310-millimetre tread on the rear axle. The intelligent aluminium-steel composite construction ensures maximum rigidity and a lightweight body. Ready to race, the 911 GT3 Cup weighs in at just 1,200 kilograms.

During the car’s development, the engineers put special emphasis on driver safety. The driver is protected by a solid safety cage and an innovative, bucket-style racing seat that is moulded around the head and shoulder area in particular. The rescue hatch in the roof, in line with the latest FIA standard, makes it easier to provide initial treatment and recovery following an accident.

911 GT3 Cup still the best-selling GT racing car

Porsche manufactures the 911 GT3 Cup on the same production line as the 911 road car in its main facility in Stuttgart-Zuffenhausen. The baseline race tuning is performed at the Weissach Motorsport Centre, where vehicles are also thoroughly tested by a professional race driver prior to delivery to the customer. From 1990 to the end of 2019, Porsche produced and prepared a total of 4,251 units of the 911 GT3 Cup in race trim. This makes the one-make cup contender still the best-selling GT racing car in the world. The 911 GT3 Cup can be ordered from Porsche Motorsport in Weissach for a price of 196,880 Euro plus country-specific taxes.
