Chapter 1: Own & Drive the DeLorean
To begin the ‘Blast From the Past’ challenge in Forza Horizon 6, you must own and drive the 1982 DeLorean DMC-12. If you don’t already have this iconic car in your garage, you can unlock it for free by completing the “Street Runner” challenge within the Horizon Decades Summer season. Alternatively, it is available for purchase via the Autoshow or Auction House.

Chapter 2: Maintain 88 MPH for 10 Seconds
In a nod to Back to the Future, this chapter requires you to maintain a speed of at least 88 MPH (142 km/h) for 10 consecutive seconds. The easiest way to achieve this in FH6 is to head to the main highway or a long stretch of coastal road. Using the custom tune provided below (431 370 330) will ensure your DMC-12 has the acceleration needed to hit and hold this target speed easily.

Chapter 3: Photograph the DeLorean
Once you’ve cleared the speed requirement, pull over and open Photo Mode (Up on the D-pad). You simply need to take a promotional photo of the DeLorean DMC-12 to trigger the completion of Chapter 3. For the best “Decades” vibe, try taking the photo near the neon lights of the festival hub or during a sunset on the Japanese coast.

Chapter 4: Win a Road Race
The final stage requires you to win a Road Racing Circuit or Sprint event. To make this trivial, use the Tune Code: 431 370 330. This setup improves the DeLorean’s handling and top speed, making it highly competitive against Highly Skilled Drivatars. Choose a short circuit like the downtown city loop to finish the challenge quickly and earn your Five Festival Playlist points.
