- Buyers of the new GT 63 typically come from other Mercedes-AMG models.
- The sleek two-door has many similarities to the Porsche 911 but also a unique appeal.
- In terms of power, the GT 63 Pro sits between the 911 GTS T-Hybrid and 911 Turbo S.
The new Mercedes-AMG GT 63 Pro may offer similar performance to models like the Porsche 911 GTS T-Hybrid and the raging 911 Turbo S, but according to Mercedes, buyers of its new front-engined flagship aren’t cross-shopping with any Porsche.
Obviously, Porsche 911s differ from any other sports car on the market as they’re rear-engined, but like the GT 63 Pro, they’re sleek two-door models with 2+2 seating layouts, and ferocious levels of performance, particularly in Turbo S configuration. The Mercedes is also priced similarly.

However, while speaking with Drive at the recent Australian launch of the GT 63 Pro, the head of Mercedes-Benz’s local media relations, Jerry Stamoulis, said buyers are more likely to come from other AMG products.
“To be honest, the typical AMG owner isn’t going to cross shop these cars,” he said. “Customers for the GT 63 Pro are more likely to come from a G63, and now they want a sports car instead, or as well. E63 AMG as well.”
AMG vs Porsche
In terms of outright performance, the GT 63 Pro certainly has the chops to take it to some of the finest Porsche 911 models. Power comes courtesy of a 4.0-liter twin-turbocharged V8 delivering 603 hp and 627 lb-ft (849 Nm) of torque, healthy gains of 26 hp and 37 lb-ft (50 Nm) over the regular, non-Pro version.
Mated to this engine is a nine-speed transmission driving all four wheels. Mercedes-AMG says the car needs just 3.1 seconds to hit 60 mph (96 km/h) and won’t stop accelerating until it hits 197 mph (317 km/h).
The AMG’s power figures sit between the 911 GTS T-Hybrid and the new 911 Turbo S. Thanks to a twin-turbo 3.6-liter flat-six, the GTS is good for 532 hp and 449 lb-ft (609 Nm), while the Turbo S ups these numbers to 701 hp and 590 lb-ft (800 Nm).
