Overview

Specs

Figures below are from Porsche press and technical data. U.S. and European publications sometimes list different power, torque, and top speed; both columns are here, labeled, instead of a blended number this site cannot defend.

The 4.0 that still has to be revved

The 992 GT3’s engine is a 3,996 cm³ naturally aspirated flat-six with a 9,000-rpm limit. Porsche Cars North America introduced it as a 2022 model with 502 hp and a Cup-car kinship. European data lists 375 kW (510 PS) at 8,500 rpm and 450 Nm at 6,250 rpm. Individual throttle bodies and dry-sump lubrication are part of the same brief: keep the engine alive at race-car loads.

Performance (published)

Performance (published)
Item	Figure	Source
0–60 mph (PDK, U.S.)	3.2 seconds	[1]

Nürburgring Nordschleife (992.1)	6:59.927 Full 20.832 km / 12.944 mile layout. Development driver Lars Kern, during final testing.	[1]
Nürburgring Nordschleife (992.2, published 2025)	6:56.294 Porsche published this time for a 992.2 911 GT3 with six-speed manual and optional Weissach Package, on the same 20.832 km layout, as the fastest official lap of a production car with a manual gearbox at the time of the announcement.	[5]

Mass

Mass
Item	Figure	Source
Launch mass (manual)	1,418 kg Porsche’s June 2021 Touring-package press release.	[4]
Launch mass (PDK)	1,435 kg	[4]
DIN unladen (winged GT3, PDK sheet)	1,479 kg Later European technical data. DIN figures include more of the car than some headline launch masses; they are not a contradiction so much as a different column.	[2]
DIN unladen (Touring, PDK sheet)	1,477 kg	[3]

Aerodynamics

Aerodynamics
Item	Figure	Source
Winged GT3	Swan-neck rear wing, large rear diffuser, adjustable front lip Porsche said even the road (“normal”) aero setting produced up to 50% more downforce than the previous GT3; a track-only performance setting increased that to about 150%.	[1]
Touring	No fixed swan-neck wing; automatically extending rear spoiler Same mechanical package. The Touring package was a no-cost option at European launch and, for the first time, could be combined with PDK.	[4] [3]
Drag (European PDK sheets)	cd 0.35 (winged) / 0.32 (Touring)	[2] [3]

992.1 and 992.2

992.1 is the car launched in 2021 for the 2022 model year. 992.2 is the facelifted GT3 Porsche ran at the Nordschleife in 2025. This site treats them as one generation unless a source is generation- specific. The 6:56.294 Nordschleife time is a 992.2 figure for a manual car with the Weissach Package; the 6:59.927 time is the 992.1 development lap Porsche published in 2021. Engine output in the materials cited here remains 375 kW / 510 PS (502 hp in U.S. copy).
