Race 1: Tunnel Run Street Race
The first event in the Forza Horizon 5 Retro Street series is the Tunnel Run. This track is characterized by long, sweeping bends and high-speed sections through the heart of the tunnels. The key here is maintaining momentum; avoid heavy braking where a slight lift will suffice.
The Honda Civic Type R’s power delivery allows you to pull away from the AI on the exit of the tunnels. Keep your racing line tight to the interior walls to minimize distance and maximize your top speed on the straights.

Race 2: Guanajuato Sur Street Circuit
Guanajuato Sur is one of the most technical tracks in the game. With narrow alleys and unforgiving 90-degree turns, precision is more important than raw speed. This is where the C-Class tune really shines, providing the grip needed to navigate the cobblestone streets without sliding into buildings.
Look for braking markers early, especially when approaching the downhill sections. The AI often bundles up in the tight corners, so use the first few turns to pick off positions while defending your line on the inside.

Race 3: Hilltop Descent Challenge
The final race to secure the Retro Street championship is the Hilltop Descent. This route features high-elevation changes and rapid descents that can upset a car’s balance. Because we are using a front-wheel-drive setup, be mindful of understeer during high-speed downhill corners.
Once you clear the technical upper sections, the race opens up into faster segments. Stay focused on your apexes to ensure you cross the finish line in first place, securing your 5 points for the Festival Playlist.
