Overview
2013 SRT Viper GTS 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 SRT 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
Chrysler's last Viper generation moved the brand to SRT Performance, then back to Dodge in 2014. The 8.4-litre naturally aspirated V10 made 640hp with a six-speed manual — no automatic was ever offered. Production ended in 2017 when the Conner Avenue Assembly plant in Detroit closed. On the official Forza Horizon 6 car list this 2013 SRT 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 2022 Acura NSX Type S and 2021 Alfa Romeo Giulia GTAm, which is the S1 Class (supercar tier) peer group this car is usually weighed against.
Driving feel in Forza Horizon 6
SRT Viper GTS was Chrysler's last Viper generation under SRT Performance branding — 8.4 naturally aspirated V10 making 640hp through a six-speed manual (no automatic ever offered). In S1-class events on Japan's longer routes the Viper's V10 torque is the appeal; production ended in 2017 when the Conner Avenue Assembly plant in Detroit closed.
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 2013 SRT Viper GTS
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.
