The “Theory of Evolution” Weekly Challenge in Forza Horizon 6 sends you through a four-part checklist using the 2001 Mitsubishi Lancer Evolution VI GSR TM Edition. You can jump into it after earning the Rookie Yellow wristband during the main story, and you may even have already knocked out the opening step while progressing through the campaign. Here’s a task-by-task breakdown to help you finish the whole challenge.
Key takeaways
- The challenge becomes available after you earn the Rookie Yellow wristband in the main story.
- All four tasks are located in the Winter Festival Playlist under the “Theory of Evolution” section.
- You must use the 2001 Mitsubishi Lancer Evolution VI GSR TM Edition for every step.
- Task 2 requires three laps at the Sekibe Time Attack circuit, aiming for personal bests but not enforcing them.
- Task 3 asks for three stars at the Festival Loop Speed Zone with an average target speed of 90 MPH.
- The final step is a win in a Dirt Race, and you can lower race difficulty via custom settings if needed.
How to start and find the Theory of Evolution Weekly Challenge
There are four separate tasks you’ll need to complete for the Theory of Evolution Weekly Challenge in Forza Horizon 6. You can locate them in the Winter category of the Festival Playlist. This Winter section won’t be accessible until you finish the Rookie Yellow wristband event.
Theory of Evolution Task 1: Get a 2001 Mitsubishi Lancer Evolution VI GSR TM Edition
The 2001 Mitsubishi Lancer Evolution is an exclusive car you can buy from the Autoshow. To pick it up, open the main menu and go to Buy & Used, then enter the Cars category.
From there, navigate into the Mitsubishi category. The car is listed for 70,000 Credits.
Once the purchase is done, the first task is straightforward: get out on the road and drive around for just a few seconds. That brief driving period completes Task 1 and unlocks the next objective.
Theory of Evolution Task 2: Complete 3 laps at the Sekibe Time Attack
For Task 2, you’ll take the 2001 Mitsubishi Lancer Evolution to the Sekibe Time Attack circuit. Your job is to complete three full laps while driving the vehicle.
Sekibe Time Attack is located to the east of Tokyo City in the Ito Region. When you arrive, go to the race starting line. You’re free to begin at any time, since you’re not racing other players—this is you-versus-yourself timing for each lap.
Your personal preference is to beat your previous time, but for this Weekly Challenge the requirement is only to finish three laps. Slower driving won’t penalize you for this step, so focus on completing the set rather than chasing a perfect score.
After you complete three laps at Sekibe, Task 2 is done and you can move on to Task 3.
Theory of Evolution Task 3: Earn 3 stars at the Festival Loop Speed Zone
Task 3 is where you’ll need to lean into speed and consistency. You must earn three stars at the Festival Loop Speed Zone using the 2001 Mitsubishi Lancer Evolution.
This Speed Zone is in the Ohtani region, positioned to the northwest of Tokyo City. If you haven’t been there before, you can use the Horizon Festival Site as a fast-travel starting point.
The Speed Zone objective is to pass through it while holding an average speed of 90 MPH. Maintaining that average can be tricky with the default 2001 Mitsubishi Lancer Evolution, so upgrading beforehand helps a lot.
A practical recommendation is to open the Change Car area in your main menu, then upgrade the 2001 Mitsubishi and bring it up to at least S1 class. The upgrade cost is 55,000 Credits. With that extra performance, hitting the Speed Zone requirement becomes significantly more manageable.
When you’re ready to attempt the zone, you can start from either side. The guide’s suggestion is to begin from the west side, since it tends to make it easier to build up higher speeds. Also try to enter the zone at around 100 MPH or faster, because you’ll need enough momentum to handle the various turns and curves inside the Speed Zone.
By the time you reach the end, you’re hoping your average speed shows up as 90 MPH. If it doesn’t count right away, you may need multiple attempts to learn where to turn and when to brake for clean runs. If you run too far off the road, you’ll fail the challenge for that attempt and have to try again.
Theory of Evolution Task 4: Win a Dirt Race
The last task gives you more flexibility than the previous ones. You need to win a Dirt Race while driving the 2001 Mitsubishi Lancer Evolution.
You can choose any Dirt Race you want to complete. If you’re looking for an easier route, it’s recommended to either pick a Dirt Race you’ve already won or run one once first so you can adjust your setup. From there, use the race’s custom options to change drivers and lower the difficulty, which makes it easier to secure first place.
If you want one near the Festival Loop, there’s a nearby Dirt Race called Chiheisen Scramble. It also allows the 2001 Mitsubishi to be selected as the default choice, which helps reduce setup friction.
Start the race whenever you’re ready and push to finish in first place to win. If the default difficulty still feels too hard, the same fallback applies: complete the race at least once, then create a custom Dirt Race where the other drivers are set to a lower difficulty. That should make reaching first place more achievable.
Once you finish this final win, you’ll have completed all of the Theory of Evolution Weekly Challenges in Forza Horizon 6.
