Overview
1970 Porsche #3 917 LH 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 Porsche 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
Long-tail 917s used a streamlined body shape to maximise Mulsanne Straight speed at Le Mans. The flat-12 5.0-litre engine produced over 600hp in race trim; Vic Elford and Kurt Ahrens drove a long-tail 917 LH to pole at Le Mans 1970, posting an average lap speed unheard of at the time. On the official Forza Horizon 6 car list this 1970 Porsche 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 1970 Ferrari 512 S and 1985 Ford RS200 Evolution, which is the S1 Class (supercar tier) peer group this car is usually weighed against.
Driving feel in Forza Horizon 6
917 LH (Long Tail) was Porsche's high-speed Le Mans body — 4.9 or 5.0 air-cooled flat-12 making over 600hp in race trim, with a streamlined body for maximum Mulsanne Straight speed. In S1-class events on Forza's long road circuits the 917 LH behaves like the period Le Mans prototype it is; Vic Elford set pole at Le Mans 1970 with an unheard-of average lap speed.
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 1970 Porsche #3 917 LH
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.
