When Mercedes-Benz introduced the track-focused variant of its flagship sports car, enthusiasts took notice. The Mercedes-AMG GT R Pro took the already ferocious GT R and dialled up its circuit credentials. It bridges the gap between road-legal grand tourer and FIA-compliant GT3 racer. With a base price starting north of $200,000 USD (and climbing past $450,000 in international markets like Australia), it targeted drivers who demanded absolute lap-time performance without sacrificing a license plate.
Beneath the carbon-fibre skin lies a 4.0-litre twin-turbocharged V8 engine pumping out 577 horsepower and 516 lb-ft of torque. Power hits the rear wheels via a seven-speed dual-clutch automatic transaxle, pushing the car from zero to 60 mph in 3.5 seconds. Unlike its standard sibling, the Pro package isn't about raw straight-line gains; it focuses purely on aerodynamics, weight reduction, and suspension geometry to shave precious seconds off track records.
Aerodynamic Upgrades and Exterior Design
The visual changes on the Pro serve a functional purpose. Engineers in Affalterbach didn't add vents or wings for styling flair; every element creates downforce or manages thermal loads.
Up front, carbon-fibre dive planes (canards) sit on the bumper edges, generating significant front-end grip during high-speed cornering. A redesigned front splitter works alongside louvers cut directly into the front wheel arches to vent high-pressure air and reduce lift. At the rear, a prominent carbon-fibre wing features an adjustable gurney flap, letting track day drivers fine-tune balance depending on the circuit layout. To understand the full picture, we recommend the detailed article by The New York Times.
- Carbon-fibre roof with a lowered center section to drop the vehicle's gravity center.
- Lightweight carbon-fibre front splitter supported by metal brackets.
- Distinct rear diffuser framing the centered titanium exhaust outlets.
- Optional motorsport-inspired graphics package available in specific launch liveries.
Suspension Engineering and Chassis Rigidity
The core of the upgrade package hides beneath the floorboards. Mercedes-AMG fitted a manual coil-over suspension system. Owners can mechanically adjust spring preload, rebound, and compression damping without needing to remove the wheels.
Furthermore, the upper control arms on the front and rear axles use Uniball spherical bearings instead of traditional rubber bushings. These metal-on-metal joints eliminate suspension deflection under heavy lateral loads, giving drivers sharper steering feedback and more progressive breakaway characteristics. A carbon-fibre shear panel underneath the rear axle adds torsional stiffness, keeping the chassis completely flat when loading up tires through sweeping bends.
Powertrain and Performance Figures
While the engine output matches the standard GT R at 577 horsepower, the delivery mechanism benefits from updated dynamic engine mounts. These mounts constantly adjust their stiffness to minimize the mass of the V8 shifting around the engine bay during aggressive maneuvers.
The car achieves a top speed of 198 mph. Stopping power comes from standard carbon-ceramic brakes that shrug off repeated abuse during extended track sessions without suffering from pedal fade.

Track Handling Versus Daily Drivability
Living with a track-focused machine on public roads requires compromise. The mechanical coil-over setup is stiff—unforgivingly so over broken city asphalt. Potholes transmit sharp jolts directly into the cabin, and the low-slung carbon splitter demands constant vigilance over speed bumps and steep driveways.
On a smooth ribbon of tarmac, however, the car transforms. Turn-in is instantaneous, and the electronic traction control system features a nine-stage dial borrowed straight from the AMG GT3 race car. Drivers can dial in slip angles incrementally, letting the rear step out safely before the computer gently steps in to catch the slide.
Frequently Asked Questions
How many Mercedes-AMG GT R Pro models were built?
Mercedes produced the Pro as a limited run of 750 units globally, ensuring long-term collector interest.
Does the Pro have more horsepower than the standard GT R?
No, engine output remains identical at 577 horsepower and 516 lb-ft of torque. Performance gains come entirely from weight savings, aerodynamics, and suspension tuning.
What was its official Nürburgring lap time?
The car clocked an impressive 7:04.632 around the Nürburgring Nordschleife, placing it among the fastest rear-wheel-drive production cars of its era.
Can you adjust the suspension settings yourself?
Yes, the manual coil-overs feature exposed adjustment knobs allowing owners to alter compression and rebound settings at the track without specialist tools.
