Porsche has unveiled the 2021 911 GT3 Cup based on the (previewed but yet to be officially unveiled) road-going 992-generation model. 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.
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 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.
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. The all-new 911 GT3 Cup will compete in
the Porsche Mobil 1 Supercup and the national Porsche Carrera Cup series in
Germany, France, Asia and Benelux and, for the first time, North America.
Deliveries to teams are scheduled to commence in February 2021.
