All-new 510 horsepower 2021 911 GT3 Cup racing car unveiled by Porsche

  • A four-litre, water-cooled flat-six engine that produces about 510hpis powered by the all-new Porsche 911 GT3 Cup.
  • Thanks to its large turbo-spec lightweight body, one of the most striking features of the car is its optimized aerodynamics.

The new generation of its 911 GT3 Cup, the first racing version based on the current 992 generation, has been unveiled by Porsche. It is also the sports car manufacturer’s first cup racer to feature a large turbo-spec body.

The car is powered by a four-liter, water-cooled flat-six engine fitted with a sequential six-speed paddle shifter dog-type transmission, a single-mass flywheel and a three-plate sintered metal racing clutch. The race car exceeds the output of its immediate predecessor by 25 horsepower, with about 375 kW (510 hp).

At 8,400 rpm, up from the previous 7,500 rpm, the high-revving unit with dry-sump lubrication achieves peak output. Depending on the race series, there are also three different exhaust systems available. A race car can also run on synthetic fuels, thereby reducing CO2 emissions substantially under racing conditions.

One of the most striking features of the car is its optimized aerodynamics, thanks to its wide turbo-spec lightweight body. The race car also appears more muscular than before and exceeds the rear width of the previous model by 28 millimeters. It is also distinguished by its additional cooling air inlets in front of the wheels.

Thanks in part to its new swan neck rear wing that provides eleven stages of change, the new car also produces significantly more downforce than its predecessors.

Porsche’s main goal for the development of the latest 911 GT3 Cup was to improve performance, achieve a more aggressive design, easier handling and greater durability with less outlay in terms of time and maintenance. The company says that the result is reflected in many aspects of the new racing vehicle. “With its improved performance and the optimised cockpit, the new 911 GT3 is the best Cup car that Porsche has ever built,” says Jan Feldmann, project manager of 911 GT3 Cup.

From the start of the 2021 season, Porsche plans to campaign the new cup racer in the Porsche Mobil 1 Supercup as well as the national Porsche Carrera Cups in Germany, France, Asia and Benelux and for the first time in North America. The sports carmaker estimates that the lap times of the new Cup 911 should be slashed by a good one per cent, depending on the track layout.
