Overview
1998 Nissan R390 (GT1) appears on the official Forza Horizon 6 car list as a S1 Class (supercar tier) entry in the base roster. This page focuses on what the car actually means for everyday players: how it tends to drive in its class, where it fits inside Forza Horizon 6's Japan setting, how to think about a starting tune, and which other roster entries it naturally compares against.
If you found this page while searching for a single Nissan model in Forza Horizon 6, you are in the right place. Everything below is built around the official list fields (year, class, pack, manufacturer) plus plain-language player notes. We do not invent horsepower numbers, hidden upgrade paths, or unlock guarantees that the official list has not confirmed.
Background and Forza Horizon 6 context
Built to satisfy Le Mans GT1 rules, the R390 was a closed-cockpit prototype with bodywork shaped by Ian Callum. Nissan built two road cars — both retained — to satisfy the homologation. The race version finished third overall at Le Mans in 1998, one of Japan's strongest results at the Sarthe. On the official Forza Horizon 6 car list this 1998 Nissan entry sits in the S1 Class (supercar tier) bracket inside the base roster, which is the placement players come to this page expecting to confirm against the public source. Inside the same S1 Class (supercar tier) bracket, the closest comparison roster entries for players are 1986 Audi #2 Audi Sport quattro S1 and 2009 Chevrolet Corvette ZR1, which is the S1 Class (supercar tier) peer group this car is usually weighed against. The JDM tag fits the wider Japanese setting of Forza Horizon 6, where this make tends to be a focal point of cruise lobbies and theme nights.
Driving feel in Forza Horizon 6
R390 GT1 was Nissan's Le Mans GT1 entry — closed-cockpit prototype with bodywork by Ian Callum and a Nissan VRH35L 3.5 twin-turbo V8 making over 640hp in race trim. Two road cars were built for FIA homologation. In S1-class events on Japan's longer routes the R390 behaves like the GT1 prototype it largely is; the road version finished third overall at Le Mans 1998 in race trim.
Where it shines
S1 class fits faster road events, longer point-to-points and online cruise lobbies focused on supercar showcases.
Tuning starting point
Tunes here often balance launch grip vs top-end. If you mostly run open road events, prefer a tune with steadier mid-throttle response over absolute V-max.
These are general starting points only, not a guaranteed competitive setup. Forza Horizon 6 community tunes that already have hundreds of downloads are usually a faster route than building from scratch, especially if you are not sure of the car's drivetrain or aero behaviour yet.
How to get 1998 Nissan R390 (GT1)
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.
