GT2 Vs. GT3: What’s The Difference Between The Two Race-Bred Porsche 911s?
While Porsche's motorsport-inspired 911s share a common origin, find out why they're worlds apart under the skin
The 911 GT2 and 911 GT3 may look very similar
Both race-bred models have some key differences, that set them apart
Apart from the fact that both the 911 GT2 and the 911 GT3 belong to different class of endurance racing, both having distinctive driving dynamics
The 911 GT2, since its inception, carries a tuned version of the 911 Turbo's twin-turbo flat-six engine
In contrast, the GT3 is being powered by a naturally aspirated flat-six that's straight from Porsche's racing program
Among the two, the GT2's powertrain is the most capable, thanks to forced induction. Also, the torque this engine produces is much more than that of the GT3
The last 911 GT2, the 991 generation GT2 RS, was rated at 691 hp and 553 lb-ft of torque.
Side-by-side, the latest 992.2 911 GT3 cranks 510 hp 331 lb-ft
As for aerodynamics, GT3 models generally produce more downforce than GT2s
Despite the powertrain differences, both the GT2 and the GT3 drive the rear wheels only
Porsche unveiled the first 911 GT2 with the 993-gen 911, even before the GT3 came into being
Early GT models were strictly manuals, but Porsche's PDK was offered in more recent generations like the 991
The first GT3 arrived a generation later in the 996 guise, with the "fried egg" headlights in 2004
It also evolved to include RS models across the water-cooled generations of the 911
