Overview
2021 SIERRA Cars 700R appears on the official Forza Horizon 6 car list as a D Class (entry-level pace) 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 700R is SIERRA's lightweight road car evolution of the ALPHA platform, with a carbon monocoque and the same 2JZ-based powertrain detuned for street use. Production is limited to single-digit annual figures and each car is configured around the buyer's intended track use. On the official Forza Horizon 6 car list this 2021 SIERRA Cars entry sits in the D Class (entry-level pace) bracket inside the base roster, which is the placement players come to this page expecting to confirm against the public source. Inside the same D Class (entry-level pace) bracket, the closest comparison roster entries for players are 2013 Cadillac XTS Limousine and 2010 Ford Crown Victoria Police Interceptor, which is the D Class (entry-level pace) peer group this car is usually weighed against.
Driving feel in Forza Horizon 6
SIERRA 700R is the road-going lightweight evolution of the ALPHA platform — carbon monocoque and 2JZ-based powertrain detuned for road use. Production is limited to single-digit annual figures. In D-class events on Japan's mountain routes the 700R is the smallest production output of any modern carbon-monocoque sports car; the chassis behaviour is closer to a customer track day car than a road sports car.
Where it shines
Use D class entries for the lowest tier of road races, learning loops, scenic photo runs, and casual lobbies where players are picking starter cars.
Tuning starting point
Tuning at this tier is mostly about tire pressure, brake balance and gearing. A small differential adjustment can already change the car a lot.
How to get 2021 SIERRA Cars 700R
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.
