Overview
2005 Mitsubishi #1 Sierra Sierra Enterprises Lancer Evolution Time Attack appears on the official Forza Horizon 6 car list as a R Class (track-focused) 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 Sierra Sierra Enterprises Lancer Evo Time Attack car is one of the most legendary American time attack builds, with a 700+ hp 4G63T running massive boost, custom aero with double rear wings, and a sequential gearbox. It set lap records at Buttonwillow and other tracks in the late 2000s and inspired a generation of US time-attack builders. On the official Forza Horizon 6 car list this 2005 Mitsubishi entry sits in the R Class (track-focused) bracket inside the base roster, which is the placement players come to this page expecting to confirm against the public source. Inside the same R Class (track-focused) bracket, the closest comparison roster entries for players are 1990 Alfa Romeo SE 048SP and 2019 Apollo Intensa Emozione, which is the R Class (track-focused) 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
Sierra Sierra Enterprises Lancer Evolution is a Pro Class WTAC build with a built 4G63T making over 700hp on E85, full carbon aero kit and sequential gearbox. In R-class events on Forza's road circuits the Sierra Sierra car set multiple US time-attack records; the chassis behaviour is closer to a GT3 race car than a road Lancer.
Where it shines
R class is at home on the dedicated road circuits and any event where downforce, tire heat and brake bias can be used. Avoid running R class on tight street routes where the car cannot stretch.
Tuning starting point
R class needs an aero-first mindset. Set differentials around how aggressively you trail-brake, and rotate compounds based on the track surface. Rear-wheel-drive cars want a softer rear and careful throttle on corner exit; pay attention to rear tire pressure especially on long Japan map straights.
How to get 2005 Mitsubishi #1 Sierra Sierra Enterprises Lancer Evolution Time Attack
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.
WTAC and time attack context
2005 Mitsubishi #1 Sierra Sierra Enterprises Lancer Evolution Time Attack sits inside the current Forza Horizon 6 time attack slice, which players often search through pack names, exact model names, or the WTAC acronym. This matters because Google is already surfacing specific time-attack builds separately from the broader car list.
If you want the broader circuit-focused pool, open the time attack cars page. This entry does not use WTAC in its official name, so it stays grouped under the wider time attack list.
