The Double Up Treasure Hunt represents one of the most rewarding seasonal activities in Forza Horizon 5’s Autumn Series. This comprehensive guide provides detailed strategies for efficiently locating the hidden chest while maximizing your seasonal progression. Understanding the challenge mechanics first will significantly reduce completion time.
Success begins with proper vehicle selection and tuning. You must obtain the 1973 AMC Gremlin X from either the Autoshow or Auction House. This specific model provides the ideal platform for reaching the 200 mph (322 km/h) speed threshold required to unlock the treasure clue.
For optimal performance, apply tuning share code 928 873 971 which configures the vehicle with upgraded engine components, transmission, and aerodynamics. This proven setup eliminates guesswork and ensures consistent speed achievement. Many players struggle with improper gear ratios – this tune addresses that common issue directly.
After successfully hitting 200 mph with your tuned AMC Gremlin X, the game reveals the treasure location clue. The chest spawns within Guanajuato’s intricate underground passage network. Navigate to the city’s eastern tunnel system where the treasure becomes accessible.
Destroy the chest to claim your substantial rewards: 50,000 credits for vehicle purchases, 3 crucial seasonal progression points, and the exclusive Painter Hoodie cosmetic item. For players seeking comprehensive seasonal completion, our Complete Guide provides additional strategic insights.
Seasoned players can optimize their approach by combining this challenge with other Autumn Series objectives. The speed run typically takes 15-20 minutes including vehicle acquisition and tuning. Avoid the common mistake of attempting the challenge with stock vehicles – this wastes significant time.
For maximum efficiency, complete your speed attempt on the highway north of the festival site. This provides the longest straightaway for building and maintaining top speed. Understanding proper Weapons Unlock mechanics in other games can help develop the systematic approach needed for these challenges.
