Porsche started development of the new 911 GT3 Cup in early 2019 and has developed an all-new aerodynamic package for the racing car. Most notably, for the first time in a 911 Cup car, it features a wide turbo-spec bodywork, meaning the rear end is 28 mm wider than the previous-generation model.
Now that Porsche has revealed the 992-gen 911’s GT3 Cup race car, which the automaker has confirmed will be ready for the 2021 motorsport season, it has also already been confirmed for the Porsche Mobil 1 Supercup as well as the national Porsche Carrera Cups in Germany, France, Belgium, the Netherlands, Luxembourg, Asia, and for the first time in North America.
The front end is also wider than before thanks to the presence of flared wheel arches. Porsche says the new car generates noticeably more downforce than the old car, thanks in part to the new swan neck rear wing that offers eleven stages of adjustment.
The bodywork of the 991.2-generation 911 GT3 Cup was made up of 70 per cent steel and 30 per cent aluminum. For the 992 model that has been changed to 70 per cent aluminum and 30 per cent steel, while the doors, hood, and rear wing are made from carbon fiber reinforced plastic.
Powering the new 911 GT3 Cup is a 4.0-liter naturally aspirated flat-six with dry-sump lubrication that pumps out 510 hp at 8,400 rpm and 346 lb-ft (470 Nm) of torque at 6,150 rpm and revs through to 8,750 rpm. Coupled to this engine is a sequential six-speed dog-type transmission with paddle shifters, a single-mass flywheel and a three-plate sintered metal racing clutch. Three different exhaust systems are available depending on the race series.
On the outside, we can see that the GT3 Cup racer features a rear wing with swan necks struts, a design that will also make it to the road car, albeit in tamer form. The side intakes and extra vents on the hood of the GT3 Cup are unique to the race car however, as is its track-scraping ride height. As mentioned above, the width of the GT3 Cup is wider than what we’ll see on the road car. It measures 1,902 millimeters across, or about 28 mm more than the outgoing car. The wide-body design has allowed engineers to fit some massive wheels. We’re talking 12-inch wide wheels at the front and 13-inch wheels at the rear.
There have been 4,251 examples of the GT3 Cup built since the first one was rolled out in 1998, making it the most-produced GT race car in the world. We imagine the new 992 generation being even more popular than any of its predecessors.
Porsche Motorsport now delivers all Cup cars with a complete accessory kit, which includes all special tools and wishbone spacers required for track adjustment and means customer teams won’t have to order these parts individually.
