Base Mercedes-AMG GT 43 Coupe Debuts With 2.0L Engine

Following in the footsteps of its open-top sibling, the latest Mercedes-AMG SL 43 Roadster, the new GT 43 Coupe uses the same recipe: a 2.0L four-pot with an electric exhaust gas turbo whose tech was inspired by the world of F1.

According to the Affalterbach brand, the powertrain puts 416 hp (421 ps/310 kW) at 6,750 rpm and 369 lb-ft (500 Nm) of torque at 3,250-5,000 rpm under the driver's right foot. This makes it 40 hp (41 ps/30 kW) and 15 lb-ft (20 Nm) punchier than the SL 43. As a matter of fact, the entry-level roadster is identically powerful to the A 45 hot hatch, whereas the base coupe is just as punchy as the A 45 S.

The spec sheet reveals that the new GT 43 takes an estimated 4.5 seconds to reach 60 mph (97 kph), four-tenths quicker than the Mercedes-AMG SL 43, and has a 174 mph (280 kph) top speed, up from the open-top car's 170 mph (275 kph). The model is rear-wheel drive and uses a nine-speed automatic transmission. Drivers can use the AMG Dynamic Select to choose between Comfort, Sport, Sport+, Slippery, and Individual modes.

On the outside, the 2025 Mercedes-AMG GT 43 stands out next to the V8-powered GT 55 and GT 63 by featuring a different bumper, narrower front, and rear fenders, a reduced track width, and round double tailpipes. It rides on 19-inch alloys as standard, upgradable to 20- and 20-inch sets, and can be ordered with the AMG Exterior Chrome Package, AMG Night Package, and AMG Night Package II as an option for a more striking visual presence.

In the cockpit, it retains the 2+2 seating layout and benefits from the same 11.9-inch touchscreen infotainment. It also gets Nappa leather upholstery, trim elements available in carbon fiber, dark chrome, aluminum, and high-gloss black, birch wood and brown open-pore ash ship deck wood, optional AMG Performance steering wheel in Nappa leather, and Nappa leather/microfiber or carbon design/microfiber, among others.

Pricing details for the U.S. market have yet to be released, and we expect the GT 43 to launch in the coming months. For reference, the GT 55 starts at $134,900 and the GT 63 at $175,900 before destination. The former uses a 4.0L V8 with 469 horsepower (476 ps/350 kW) and 516 lb-ft (700 Nm), and the superior GT 63 enjoys 577 hp (585 ps/430 kW) and 590 pound-feet (800 Nm). We expect this model to start at just over $100,000, considering that the SL 43 has an MSRP of $109,900.
