Overview
2018 Mercedes-AMG GT 4-Door Coupé appears on the official Forza Horizon 6 car list as a A Class (sharp performance) entry in the base roster. This page covers how it tends to drive in its class, where it fits inside the Japan setting, how to think about a starting tune, and which roster entries it naturally compares against.
Background and Forza Horizon 6 context
The AMG GT 4-Door Coupé was a four-door sedan that borrowed only the AMG GT's nose and badge — underneath it was a stretched E-Class. The top GT 63 S trim used 630 hp from the 4.0-litre twin-turbo V8 and 4Matic+, directly competing with the Porsche Panamera Turbo and Audi RS7. On the official Forza Horizon 6 car list this 2018 Mercedes-AMG entry sits in the A Class (sharp performance) bracket inside the base roster, which is the placement players come to this page expecting to confirm against the public source. Inside the same A Class (sharp performance) bracket, the closest comparison roster entries for players are 2007 Alfa Romeo 8C Competizione and 2014 Alfa Romeo 4C, which is the A Class (sharp performance) peer group this car is usually weighed against.
Driving feel in Forza Horizon 6
AMG GT 4-Door uses the M177 4.0 twin-turbo V8 (in the 63 trim) making 630hp through a nine-speed automatic and 4MATIC+ AWD. In A-class events on Japan's longer routes the GT 4-Door is the four-door alternative to the GT R coupe; the trade-off is around 200kg more kerb weight over the two-door GT.
Where it shines
A class is the sweet-spot bracket for many Horizon road events, especially mid-length point-to-points and Street race playlists.
Tuning starting point
A class rewards smarter aero and gearing. Test whether a top-speed gear or a corner-exit gear suits the events you actually run.
How to get 2018 Mercedes-AMG GT 4-Door Coupé
This car is listed without an add-on label on the official Forza Horizon 6 source, so we treat it as part of the base roster. Forza Horizon 6 launches on May 19, 2026, and before that date the public Autoshow may not surface every base-roster car yet — players asking 'how do I get this car, it is not in the Autoshow?' on Reddit or the Forza forums usually find the answer is 'wait for launch day or a post-launch update'. After launch, base-roster cars are normally available through credits in the Autoshow, Wheelspins, Festival Playlist rewards, or the in-game showcase that introduces new vehicles.
