2025 Mercedes-AMG GT line-up expands

Mercedes-AMG has expanded its GT coupe line-up Down Under, cutting entry into the range with the arrival of the circa-$250k AMG GT 43, while at the same time, introducing a new flagship in the AMG GT 63 Pro.

When it lands Down Under, the 2025 Mercedes-AMG GT 43 Coupe will be the first AMG GT to come powered by a four-cylinder engine, yet no reasons have been given as to why it’s taken the German brand quite so long to introduce the 43 Down Under, given it’s been on sale since early 2024.

Borrowing its 2.0-litre turbocharged four-cylinder mild-hybrid from the C 43 sedan, the AMG GT uses a turbo that features an e-motor within, slashing lag and boosting power to 310kW/500Nm.

Combined with a nine-speed dual-clutch transmission, Mercedes-AMG claims its most affordable GT can launch from 0-100km/h in 4.6 seconds and top out at 280km/h.

Looking different to the regular twin-turbo V8 AMG GT, the entry 43 gets narrower front and rear guards and sports a different front bumper. At the rear, there's twin exhausts, instead of the quad pipes seen on more ferocious GTs.

Australian-spec AMG GT 43 models come with AMG Dynamic Plus as standard, adding a mechanical limited-slip differential, dynamic engine mounts, 10mm lower sports suspension, plus a front underbody made of lightweight carbon-fibre.

Costing around $120k less than the GT 63, the new $249,000 (plus on-roads) Mercedes-AMG GT 43 gains roll cancelling AMG Ride Control, a powerful Burmester sound system, a head-up display and matrix LED headlights.

At the top of the tree, the AMG GT 63 Pro 4MATIC+ arrives with its twin-turbocharged 4.0-litre V8 dialled up to 450kW (+20kW) and 850Nm (+50Nm) of torque.

That’s claimed to shave half a second off the 0-200km/h sprint, that drops to 10.9 seconds, although the 0-100km/h dash remains pegged at the same 3.2 seconds as the standard version. Top speed is capped at 317km/h.

Improving its ability on road and track, the faster GT gets recalibrated active suspension and aero, comes standard with rear-wheel steering and gets a tweaked full variable all-wheel drive.

Other upgrades consist of improved cooling for the engine and differentials that have been introduced for sustained high-performance driving on track.

Aero changes include a new front splitter with carbon-fibre flicks, a revised underbody and a fixed rear wing that adds an extra 30kg of downforce over the front axle and 15kg at the rear.

Coming standard with 21-inch rims, AMG Performance seats and steering wheel, the Pro gets an even more powerful 1170W 15-speaker Burmester stereo.

Options include an AMG Night pack ($1900) for darkened elements, plus an AMG Carbon Fibre pack ($5200) that introduces carbon exterior elements while inside, the centre console, doors and steering wheel are all made from the same weight-saving composite.

While some performance car fans might turn their nose up at the sound of an AMG GT with a turbo-four tucked under its snout, the six-figure saving over the V8 and the $30,000 discount over the cheapest Porsche 911 proves plenty incentive for what is still set to be a very capable sports car.

The $418,900 (plus ORCs) charged for the wilder AMG GT 63 Pro, meanwhile, might be more of a challenge to justify the extra $48,500 over the already fast GT 63, unless you regularly venture out on track.
