If you are diving into the beautiful Japanese roads of Forza Horizon 6, there is probably one legendary machine sitting right at the top of your wishlist: the Mazda #55 Mazda 787B (1991). With its iconic green-and-orange Renown livery and that unforgettable, screaming quad-rotor Wankel engine, this car isn't just a piece of motorsport history—it's an absolute meta monster on the track.

However, if you've tried looking for it on the Auction House to skip the line, you already know the bad news: the game completely blocks players from buying or selling unlocked Barn Finds. If you want this masterpiece in your garage, you have to earn it the old-fashioned way.

Fortunately, you don't have to wander aimlessly around the map. Here is the ultimate, optimized speedrun strategy to unlock the Mazda 787B as fast as humanly possible.

1. Fast-Track Your "Discover Japan" Campaign

The backbone of progression in Forza Horizon 6 revolves around the "Discover Japan" journal, which replaces the classic wristband system from previous games. To get your hands on the 787B, you need to hit Level 7: Master Explorer to secure the final Golden Stamp.

If your goal is pure speed, stop treating the game like a casual driving simulator for a few hours and focus on these campaign efficiencies:

• Laser-Focus on Campaign Objectives: Ignore optional free-roam distractions, side boards, and random exploration. Pour all your time into core race events, PR stunts, and showcase challenges that explicitly reward progression points toward your journal stamps.

• Drop the Difficulty: There is no shame in lowering the AI Drivatar difficulty when you are on a specific unlock grind. Setting the AI to an easier level ensures you clear races on your first attempt, banking stamp completion rewards rapidly without frustrating restarts.

• Push to Level 7: As you climb the ranks, you will unlock intermediate barns, but keep your eyes on the prize. The moment you hit Level 7 (Master Explorer) and claim that final Golden Stamp, the 787B Barn Find rumor will trigger on your map.

2. Head Directly to the Hidden Barn Location

Once the rumor circle appears on your map, do not waste precious fuel searching every grid square. The barn is tucked away in a specific corner of the map, and you can drive straight to it to trigger the cinematic.

• The Region: Head to the northern area of the map to the Takashiro region, located close to the Sunny Circuit.

• The Landmark: Look closely at your map for a very distinct, sharp U-shaped road layout within Takashiro.

• The Hidden Path: Drive toward the right side of this U-shaped loop. Keep your eyes peeled for a small, inconspicuous dirt path that breaks off from the main asphalt road and heads downward. Follow this path directly to the hidden barn doors, and the cutscene will automatically trigger.

3. Skip the Restoration Wait Time

Finding the barn is only half the battle. When you pull the Mazda 787B out of hiding, it is in a heavily deteriorated, damaged state. Under normal circumstances, the game forces you to wait out a lengthy, real-time restoration process while your garage mechanics work on the vehicle.

If you want to take it to the track immediately, use this bypass shortcut:

• Open the Menu: Travel to any Horizon Festival site or your owned Player House and open up the Barn Finds menu.

• Buy It Out: Select the 787B and look for the option to pay an in-game credit fee for an instant restoration.

• Hit the Track: While this shortcut can be quite expensive depending on your current bank balance, it completely skips hours of real-world waiting. The car will be fully restored, tuned, and added to your active garage instantly.

By focusing purely on campaign stamps, driving straight to the Takashiro coordinates, and paying off the restoration fee, you can bypass days of casual progression and get right to tearing up Forza Horizon 6 with one of the most iconic race cars ever built. See you on the track!
