The Chevrolet Corvette ZR1’s Road Atlanta benchmark has been beaten by a Porsche 911 GT2 RS, a car whose basic formula dates back to 2017.
The lap time was 1 minute 22.649 seconds, just ahead of the ZR1’s 1 minute 22.82-second run, but the margin matters on a circuit as fast and technical as Road Atlanta.
Manthey Racing turns the GT2 RS into a sharper weapon
The car that set the time was a 2019 model-year 911 GT2 RS equipped with the optional Manthey Racing kit.
That package is designed to extract more from the GT2 RS on circuit, with a focus on aerodynamic balance, chassis precision and sustained pace rather than outright power alone.
It also improves significantly on the GT2 RS’s own previous Road Atlanta production-car mark of 1 minute 24.88 seconds, set in 2019.
Why Road Atlanta suits a car like this
Road Atlanta rewards confidence under braking, stability through high-speed direction changes and traction on corner exit.
Those are exactly the areas where the rear-engined Porsche, especially in Manthey specification, can exploit its aero and setup advantages.
The result is a lap that underlines how effective a well-developed track package can be, even when the underlying car is no longer new.
A close fight with America’s flagship Corvette
The Corvette ZR1 remains a formidable benchmark, and the difference between the two cars is measured in tenths rather than seconds.
Still, the Porsche’s 1:22.649 shows that the GT2 RS has lost little of its edge against newer, more powerful performance machinery.
For collectors and track-day drivers, it is another reminder that the GT2 RS is not merely a headline horsepower car, but one of the most complete circuit-focused 911s of the modern era.
