There are certain cars in motorsport history that transcend basic performance statistics and become true legends. The 1991 Mazda #55 Mazda 787B is exactly that kind of machine. Famed for its screaming quad-rotor engine and its historic victory at Le Mans, it is easily one of the most anticipated and sought-after additions to the car list in Forza Horizon 6.
If you have been saving up credits hoping to grab this beast from the Autoshow or keeping an eye out for one on the Auction House, you can stop refreshing your menus. The 787B is locked behind the game's endgame progression as a final, ultimate Barn Find. It cannot be purchased or traded, meaning the only way to get your hands on it is to get out there, explore Horizon's beautiful rendition of Japan, and earn it yourself. Here is a natural breakdown of exactly how to trigger the rumor, find the structure, and add this legendary racer to your garage.
1. Reaching "Master Explorer" Status
The Barn Find rumor for the Mazda 787B will not just pop up early on. Because it is considered a premier endgame reward, the game requires you to put serious work into the campaign before the local rumors reveal its location. You will need to hit Level 7 in your campaign progression to achieve "Master Explorer" status.
- Grind Campaign Points: Keep a close eye on the yellow map markers indicating main story missions. Completing these, along with specialized touge battles, high-speed road races, and smashable regional mascots, will push your progression forward quickly.
- Track Your Progress: Open up your menus and pull up the "Discover Japan" Collector's Journal. This keeps an exact record of your stamps and lets you know how close you are to the next tier.
- Unlock the Gold Stamp: Reaching Level 7 awards you the final Gold Stamp. The moment you achieve Master Explorer status, the radio will crackle to life, and the map will trigger the final two legendary barn finds in the game—one of which is our Mazda.
2. Tracking Down the Hidden Barn
Once the rumor circle highlights your map, you will want to head toward the northern/north-eastern sector of the country. The location is nestled deep within the Takashiro region, sitting just a short distance away from the Sunny Circuit layout. Finding the actual structure requires a bit of off-road navigation, so bringing an AWD vehicle or a capable rally build can make things a bit easier.
- The Exact Route: Look closely at your map layout for a wide, sweeping, U-shaped asphalt road wrapping right along the edge of a dense forest line. Once you are at the top curve of this U-shaped section, pull over.
- The Off-Road Path: Look northeast from the top of the curve. You will spot a small, subtle dirt clearing cutting directly away from the main pavement and into the thick treeline. Turn off the asphalt and follow this narrow dirt trail straight through the woods.
- The Barn Structure: If you follow that hidden dirt path directly to its end, the trees will open up slightly to reveal an old, secluded wooden barn structure. Drive right up to the doors to trigger the cinematic cutscene and officially claim the car.
3. Restoration and Recovery
When you pull the tarp off, you will find that the 787B has seen much better days. It is heavily damaged from decades of neglect and requires serious restoration work before it can be driven. At this point, you have two choices for how you want to handle getting it road-ready:
- Option A: Let Time Do the Work: You can simply go back to playing the game normally. Complete championship races, drift zones, or PR stunts, and the garage crew will slowly fix up the bodywork and rebuild that complicated quad-rotor powerplant over time.
- Option B: The Financial Fast Track: If you absolutely cannot wait to hear that 4-rotor engine sing, you can open up your wallet. Bypassing the restoration wait time requires paying a hefty credit fee, but it instantly drops the fully restored, pristine racing machine straight into your garage.
Whichever route you choose, once the restoration process concludes, you will own an absolute masterpiece of automotive engineering—ready to conquer the highways, circuits, and winding mountain passes of Horizon Japan.
