The Mercedes-AMG GT 43 is a four-cylinder, rear-wheel drive Porsche 911 rival

The Mercedes-AMG GT has been defined by its barrel-chested 4-litre V8 engine since the model’s inception in 2014, but now, its cylinder count has been slashed in half. Meet the AMG GT 43 – a turbocharged four-cylinder variant positioned below the V8-engined GT 63.

aria-label="Mercedes AMG GT 43 reveal pictures 5"That the AMG GT has gained a four-pot option isn’t much of a surprise, given that the closely-related SL received the ‘43’ treatment last year. As in the drop-top grand tourer, the GT 43 gets AMG’s mild-hybrid M139 2-litre motor and moves from four to rear-wheel drive. The new model won’t be offered in the Australia, however, with Mercedes only selling the GT 63 on our shores.

aria-label="Mercedes AMG GT 43 reveal pictures 4"With outputs of 310kW and 500Nm, the GT 43 sprints from 0-100km/h in 4.6sec, running on to a top speed of 280km/h – that puts it 1.4sec and 35km/h behind the V8 model. Beyond the raw numbers, Mercedes has worked to improve the responsiveness of the engine by using the F1-derived electric exhaust gas turbocharging technology already found in the SL 43 and A45 S hot hatch. With a 48v electric motor driving the turbo shaft, the system can build boost pressure before the exhaust gases spin the compressor wheel, reducing lag at all engine speeds.

aria-label="Mercedes AMG GT 43 reveal pictures 7"The engine is hooked up to a nine-speed automatic gearbox, which uses a wet clutch rather than a torque converter for more direct throttle response and quicker shifts. The more compact engine and the switch to two-wheel drive will undoubtedly trim a few kilos from the GT 63’s 1970kg kerb weight – Mercedes hasn’t released an official figure, but the SL loses around 230kg in 43 spec.

aria-label="Mercedes AMG GT 43 reveal pictures 8"Like its big brother, the GT 43 gets the forged aluminium suspension arms, steering knuckles and wheel carriers to reduce unsprung mass, with optional AMG Ride Control including switchable adaptive dampers. Rear axle steering is also available at extra cost, along with an AMG Dynamic Plus pack that bundles dynamic engine mounts, an electronically controlled locking differential and a Race driving mode.

aria-label="Mercedes AMG GT 43 reveal pictures 2"The GT 43 gets 19-inch alloys as standard (sizes up to 21 inches are available), and the braking package measures at 390mm and 360mm at the front and rear respectively.

aria-label="Mercedes AMG GT 43 reveal pictures 6"Unfortunately,  Australian customers interested in this cheaper, lighter, rear-drive AMG GT are out of luck. Mercedes has no plans to sell the GT 43 on our shores, meaning that the cheapest (relatively speaking) version remains the $399,900 plus on-road costs.
