Porsche Heritage Moments Finale: 997 GT2 Secrets Revealed

Why the GT2 Matters

The narrative starts in the 1970s when Porsche introduced turbocharging to its 911 range, beginning with the 930 Turbo in 1974. Krickelberg brings up Hans Mezger, the legendary engineer whose contributions to Porsche cannot be understated. Mezger’s 3.3-liter turbocharged flat-six, first introduced in the 930 Turbo, laid the foundation for the GT2 lineage.

Initially plagued by turbo lag and often described as the infamous Widowmaker, the Turbo evolved through decades of technological refinement, culminating in the current 992.1 Turbo S. The 993 GT2, introduced in 1995, carried the Mezger DNA proudly with its 3.6-liter twin-turbo engine. The 996 built upon that formula with even more power, sans traction control.

Looking at the 997 GT2 showcased here, while its Turbo counterpart introduced variable turbine geometry (VTG) to eliminate lag, the GT2 took that same VTG-equipped engine and dialed it up to 530 horsepower. Unlike the Turbo’s all-wheel-drive system and driver aids, the GT2 relied solely on rear-wheel drive, making it unforgiving in the wrong hands. It’s essentially the Turbo’s evil twin: it looks like a 911, but drive it poorly, and it’ll bite.

Highlights of the 997 GT2

Porsche’s clever application of Variable Turbine Geometry (VTG) to gasoline engines was a game-changer, debuting in the 997 Turbo. Unlike traditional turbos, which suffered from lag, VTG allowed the 997 Turbo to achieve peak torque at just 1,950 RPM. What I found particularly interesting is how this [tech was adopted into motorsport in the 919 Le Mans racer.](https://newsroom.porsche.com/en/christophorus/porsche-christophorus-every-component-is-a-masterpiece-919-hybrid-13176.html) Usually, it’s the other way around, where tech from race cars trickles down into road cars. GT2 models, especially the 997 and 991, also pushed aero to extremes. Adjustable spoilers, wide rear arches, and aggressive front splitters defined these cars visually and functionally.

• Power: 530 horsepower delivered with a savage linearity. No turbo lag, just relentless acceleration

• Weight Reduction: At 3,174 lbs, it shed weight through measures like lightweight glass and carbon-fiber panels. That’s about 400 lbs lighter than a comparable Turbo S from the time

• Aerodynamics: An aggressive rear wing and a redesigned front splitter ensured optimum downforce (660 pounds)

• Technology Borrowed shared with Racing: VTG and ceramic brakes, tech also featured in Porsche’s motorsport programs, were standard

Looking Ahead: The Rumored 992.2 GT2 RS

After the 997, we got the 991.2 GT2 RS by Manthey Racing which by the way is the second quickest production car around the Nürburgiung with a time of 6:43.30. But nothing since then and there we didn’t get a follow-up for the 992 generation. But based on some recent spy shots, it appears that the GT2 nameplate may be returning as part of the .2 update for the 992. Speculation suggests it will adopt the hybridized tech, as the upcoming 992.2 Turbo S will take this route. Expect the 992.2 GT2 RS to pack in excess of 800 horsepower, likely paired with a wider torque band than ever, courtesy of advanced VTG or electric-assist systems. While purists may lament this as the end of the analog era, I see it as evolution; a necessary evil to ensure the GT2’s survival.
