Yahoo Autos 2023 Mercedes-AMG GT2 Pro is a 750-hp no-holds-barred race car
The second-generation Mercedes-AMG GT made its debut earlier in 2023, but the brand isn't done racing the original model. It unveiled a track-only model called GT2 Pro that's based on the existing GT2 but that wasn't developed to be homologated in a specific race series.
Choosing not to follow the homologation rules of a series, like the FIA's World Endurance Championship (WEC), has pros and cons. On one hand, you won't see the GT2 Pro lined up on the starting grid of a big-name race such as the 24 Hours of Le Mans. On the other hand, the engineers who designed the car were unrestricted by rules except for the ones they set for themselves during the development process.
Power comes from a 4.0-liter V8 engine that's twin-turbocharged to develop 707 horsepower, which is on par with the GT2's output, but a new feature called Push2Pass increases that number to 750 for short bursts of time. The engine spins the rear wheels via a six-speed sequential transaxle whose gear ratios have been modified compared to the gearbox that AMG puts in the standard GT2. The carbon fiber torque tube that connects the engine to the transaxle remains, and AMG also installed four-way-adjustable shock absorbers on both axles.
