Handcrafted AMG 2.0-liter turbo
engine produces 416 horsepower   

(March 20, 2024) Mercedes-AMG is expanding the portfolio of the new AMG GT Coupe with the 2025 Mercedes-AMG GT 43. The lightweight, Handcrafted AMG 2.0-liter turbocharged engine in conjunction with rear-wheel drive offers a highly dynamic driving experience and agile handling. The hand-built M139 AMG 2.0-liter turbocharged engine delivers 416 hp and 369 pound-feet  of torque to enable acceleration from 0 to 60 mph in 4.5 seconds.

It features electric exhaust gas turbocharger technology derived from Formula 1 for spontaneous throttle response across the entire rpm range. The turbocharger is operated via the 48-volt on-board electrical system, which also feeds the belt-driven starter generator (RSG). The second generation RSG also functions as a mild hybrid in the 48-volt on-board electrical system, which, in addition to providing support at lower engine speeds, also enables functions such as gliding and recuperation for even greater efficiency. The 48-volt technology also increases comfort, as the transitions between start-stop and gliding functions are almost imperceptible.

"Our AMG GT family is at the top of our portfolio and embodies the spirit of our brand: Driving Performance. We are therefore delighted that this family is now growing to include the GT 43. It is clearly recognizable as a GT but is clearly different from the other models," said Michael Schiebe, CEO of Mercedes-AMG GmbH, and head of Business Units Mercedes-Benz G-Class & Mercedes-Maybach

"It appeals to customers who love design and focus on elegance but are unwilling to compromise on driving pleasure and driving dynamics. The rear-wheel drive concept makes the GT 43 a very agile vehicle that will put a smile on your face on winding roads."


The operating principle of the electric exhaust gas turbocharger is based on the same technology that is also used by the Mercedes-AMG Petronas F1 Team. A 1.6-inch-wide electric motor is integrated directly on the shaft of the turbocharger between the turbine wheel on the exhaust side and the compressor wheel on the intake side. Electronically controlled, this directly drives the shaft of the turbocharger and thus accelerates the compressor wheel before the exhaust gas flow takes over in a conventional manner.

This significantly improves immediate throttle response from idle speed and across the entire rpm range. The combustion engine reacts even more spontaneously to accelerator pedal input, while the overall driving experience is more dynamic. In addition, the electrification of the turbocharger enables higher torque at low rpms. This also increases agility and optimizes acceleration from a standstill. Even when the driver takes their foot off the accelerator or applies the brakes, the innovative technology maintains boost pressure at all times to ensure a continuously direct response.

The AMG SPEEDSHIFT MCT 9G transmission (MCT = Multi-Clutch Transmission) is equipped with a wet start-off clutch in place of a torque converter. This reduces weight and, thanks to its lower inertia, optimizes response to accelerator pedal input, especially during spurts and load changes. The elaborately calibrated software ensures short shift times and quick multiple downshifts when required.

In addition, the intermediate throttle function in the "Sport" and "Sport+" drive programs contributes to the dynamic driving experience. The RACE START function is also applied, which guarantees optimal acceleration from a standstill.


As standard, the AMG GT 43 is equipped with the AMG steel spring suspension with high-performance aluminum shock absorbers and lightweight coil springs. The multi-link front axle is designed with all five links arranged entirely within the wheel. This significantly improves kinematics. A five-link space construction also guides the wheels on the rear axle.



To reduce unsprung mass, all suspension links, steering knuckles and wheel carriers on the front and rear axles of the new GT are made of forged aluminum. The multi-link concept guides each wheel with minimal elastic movements. The high camber and toe rigidity enables high cornering speeds and optimal road contact in the high cornering limit. This is reflected in excellent lateral dynamics and driving stability at high speeds, as well as in the good-natured response to external influences such as crosswinds, bumps in the road, or changes in road surface conditions.

The lightweight coil springs feature a special tempering for a lower weight without reducing performance. During the manufacturing process, the spring pad is glued to the spring. This solid connection prevents wear and tear caused by dirt and debris over the course of the vehicle's life. The spring does not corrode over its lifecycle and the maximum component load can be increased with less weight. This saves approximately 0.4 pound per spring.

Another lightweight construction measure concerns the torsion bar stabilizers on the front and rear axles of the AMG GT 43. The variable wall thickness allows for further weight reduction. The maximum wall thickness is only used where required due to the maximum load – in this case in the area of the rubber mounts.

The exterior design of the AMG GT 43 features a number of unique details that differentiate it from the rest of the AMG GT model series. Particularly striking is the newly designed front fascia with large air inlets across the entire width of the vehicle. Narrower front and rear fenders and the reduced track width emphasize the vehicle's elegant character. The front fenders also feature a new trim element. The rear fascia is also unique to the AMG GT 43 with round double tailpipe trim accents.

The defining features of the AMG GT body design include the long wheelbase, short overhangs, long hood and steeply raked rear windshield give the coupe its powerful, dynamic appearance – together with the wheels that are flush with the body. 19-inch AMG alloy wheels are fitted standard. Optional 19 and 20-inch wheels are also available, in addition to 21-inch forged wheels.

The large EASY PACK trunk lid with HANDSFREE ACCESS makes loading and unloading easier. The standard 2+2 seating offers increased versatility for everyday use with foldable rear seat backrests for expanded cargo space.
