Be sure to complete the task! The Shimanoyama Circuit track is located in the western part of the map in the regular region. This track is easy to find, it is north of the Horizon festival grounds and southwest of the pale green fields.

If you already know how to get to the place and have arrived, you need to drive to the blue icon and press the action button. The event "Eclectic Domestics" will start - a special race for old cars, consisting of 5 laps.

Guide! How to easily complete the task in Horizon 6

To participate, choose this car: 

  • Nissan BE-1 of 1987
  • Honda City E II of 1984
  • Nissan S-Cargo of 1989

The mistake of most players is trying to drive only one lap, as stated in the challenge description. For everything to work, namely the script, you need to complete the race entirely and wait for the results screen. To have this task completed right away, it is worth buying an account with Forza Horizon 6.

If you return to the normal free roam mode, a message about the successful completion of the Short Circuit Challenge will appear at the bottom of the screen.  These are the rewards you will get: 

  • 5000 in-game credits
  • One point for this season

Make sure to complete the task before the timer in the "Festival Playlist" menu ends, otherwise the chance to claim the reward will be lost.
