Games and Esports Articles
The Summer season of Series 8 introduces an exciting lineup of fresh challenges centered around German automotive excellence. This thematic focus means you’ll be spending considerable time behind the wheel of premium BMW, Porsche, and Volkswagen vehicles. The Power Up Treasure Hunt represents one of the most rewarding activities this season, offering both immediate satisfaction and valuable rewards for your garage.
Seasonal events in Forza Horizon 5 follow a structured pattern where each series emphasizes specific vehicle types and driving disciplines. Understanding this framework helps you prepare appropriate cars and anticipate challenge requirements. Series 8 specifically highlights electric performance vehicles, aligning perfectly with modern automotive trends while testing your driving skills in new ways.
Your treasure hunt begins at the Trebol Speed Zone, where you must achieve at least a one-star rating using an electric vehicle. This prerequisite activates the treasure chest location on your map. Several excellent electric options are available, with the 2020 Porsche Taycan Turbo S and 2021 Ford Mustang Mach-E 1400 being particularly effective choices for this challenge.
The speed zone itself is strategically positioned along the central highway, adjacent to a distinctive cloverleaf interchange that serves as an excellent visual landmark. The stock configuration of either recommended vehicle provides more than enough performance to secure the necessary star rating, eliminating any immediate upgrade requirements.

For optimal performance, approach the speed zone from the northern entrance to maintain momentum through the sweeping curves. Electric vehicles benefit from instant torque delivery, allowing for rapid acceleration out of corners where traditional combustion engines might hesitate. This advantage becomes particularly noticeable in the transition sections between highway straights and the curved portions of the cloverleaf.
Once you’ve successfully completed the speed zone challenge, navigate westward from the Trebol location into the adjacent open field. The treasure chest spawns beneath a prominent electrical grid tower, creating a distinctive silhouette against the horizon that’s easily identifiable from distance.

Use the highway as your primary reference point, moving perpendicularly away from the road until the electrical infrastructure becomes visible. The chest typically appears nestled between the tower’s support structures, partially obscured by vegetation but clearly marked with the game’s signature glow effect once you’re within proximity.
Pro tip: Activate your drone mode after completing the speed zone to scout the area quickly without driving through rough terrain. This aerial reconnaissance can save valuable time and help you plot the most efficient route to the treasure location.
Many players unnecessarily over-prepare for the speed zone challenge, spending excessive time tuning vehicles when stock configurations perform admirably. The one-star requirement is deliberately accessible to ensure all players can participate in the treasure hunt regardless of their mechanical expertise.
Avoid attempting the treasure hunt during rainy conditions, as reduced traction can complicate the speed zone completion. Similarly, nighttime navigation makes the chest more difficult to spot, though the glow effect remains visible.
For those seeking additional challenge beyond the basic requirements, try achieving three stars in the speed zone before collecting the treasure. This approach tests your skills while completing multiple objectives simultaneously. Remember that seasonal events like this often tie into broader game completion strategies that enhance your overall progression.
Electric vehicles in Forza Horizon 5 handle differently than their combustion counterparts, with weight distribution and regenerative braking affecting cornering dynamics. Spend a few minutes familiarizing yourself with your chosen vehicle’s characteristics before attempting the speed zone for optimal results.
