Mercedes-AMG Expands GT Range With GT 43 And GT 63 PRO

Mercedes-Benz Australia has added two new flavours to the AMG GT coupé stable, one light and nimble, the other loud and relentless. The GT 43 is the lean, rear-wheel-drive performer built for grin-inducing cornering. The GT 63 PRO 4MATIC+ is the track-biased V8 with more power, more aero and more cooling to keep pace with very fast laps.
GT 43: The Lightweight Cornering Artist
Think of the GT 43 as the sprightly member of the family. Under the bonnet is a 2.0-litre four-cylinder turbo that produces up to 310 kW and 500 Nm, hustling you from 0–100 km/h in 4.6 seconds and on to a top speed of 280 km/h. The clever bit is an electric motor mounted on the turbo shaft, a trick derived from Formula 1 technology. It spins the compressor up before the exhaust takes over, which means throttle response is immediate and torque comes on early. There is also a 48-volt mild-hybrid system that can add a short burst of up to 10 kW and helps with coasting and energy recuperation.
Rear-wheel drive keeps the steering pure and the feedback honest, so this GT feels more like a proper sports car than a technical exercise. The bodywork is slightly narrower than its brothers, with reworked front and rear wings, a new front apron with large air intakes and round twin tailpipes giving it a tidier, leaner stance. Inside, it is a 2+2 with folding rear seats and up to 675 litres of luggage space when you need to be sensible.
Aerodynamics are managed by an AIRPANEL active air control system and an extendable rear spoiler. Slats behind the front inlet stay closed to save drag until cooling demands rise, and the spoiler moves through five positions from 80 km/h to balance stability and efficiency. The AMG DYNAMIC SELECT system offers up to six driving modes, from Smooth and Comfort through to Sport+, and RACE, so drivers can tailor the car’s behaviour.
Australian models come standard with the AMG DYNAMIC PLUS Package, which adds an electronic rear axle locking differential, dynamic engine mounts, yellow AMG brake calipers, a 10 mm lower ride height and a carbon-fibre active underbody aero profile in front of the engine. Comfort and convenience are not forgotten either, with AMG RIDE CONTROL adaptive suspension, a Burmester surround sound system, a head-up display, DIGITAL LIGHT headlights and a suite of driver assistance systems. The cockpit centres on an 11.9-inch MBUX touchscreen with AMG-specific displays and features such as AMG Performance and AMG TRACK PACE. For early deliveries, an AMG Prime Package will be available that adds climatised and multicontour front seats and a dashcam.
GT 63 PRO 4MATIC+: The Track-Focused Beast
If the GT 43 is the athlete, the GT 63 PRO 4MATIC+ is the rugby player who also happens to be a chess champion. Its 4.0-litre V8 biturbo has been tweaked to deliver up to 450 kW and 850 Nm, which is 20 kW and 50 Nm more than the regular GT 63. That extra shove cuts the 0–200 km/h sprint on track to 10.9 seconds and pushes the top speed to 317 km/h.
The PRO’s list of performance toys is extensive. ACTIVE RIDE CONTROL suspension with active roll stabilisation, rear-axle steering, active aerodynamics and fully variable AMG Performance 4MATIC+ all-wheel drive all work together to sharpen responsiveness. Cooling has been massively upgraded for circuit use with reinforced high and low temperature circuits, extra radiators in the wheel arches and active cooling for the transfer case and differentials to prevent boil-over during sustained hard running.
Aerodynamic upgrades are more than cosmetic. A new front apron with carbon-fibre air deflectors, a pronounced underbody profile and a fixed rear wing reduce front axle lift by more than 30 kilograms and generate about 15 kilograms more downforce at the rear. The PRO rides on 21-inch forged AMG Performance wheels in a Himalaya Grey matte finish and stops with an AMG ceramic composite braking system featuring six-piston front calipers and 420 mm front discs. Small fins under the car, similar to those on the Mercedes-AMG ONE, speed airflow under the body and work in harmony with the wing for stability at speed.
The cabin is suitably hardcore yet civilized. Standard are AMG Performance seats, a steering wheel trimmed in Nappa leather and microfibre, and a full AMG carbon-fibre interior package that includes splitter and diffuser elements. Comfort items such as climatised front seats, a head-up display, DIGITAL LIGHT headlights and the Driving Assistance Package Plus remain fitted, and the Burmester sound system can be upgraded to a high-end 3D unit for those who insist on great sound while lapping.
Visual and trim options include an AMG Night Package that darkens various exterior elements and MANUFAKTUR interior elements in black chrome, plus an optional AMG Carbon Fibre Package to extend the fibre touches across more surfaces.

In short, buyers can choose between a lithe, rear-wheel-drive coupé that rewards tiny, beautiful inputs or a V8 monster built to spend long, hot afternoons on the racetrack. Either way, the AMG GT family has become more interesting and a lot more difficult to resist.
