Forza Horizon 6 Series 4 Unlock Guide: How to Get All 10 Free Horizon Mascot Party Cars

Summary: The next major festival shift for Forza Horizon 6 goes live on Thursday, August 13, 2026. Titled "Horizon Mascot Party," Series 4 injects massive Japanese subculture-themed map overhauls, quirky EventLab blueprints, and a stellar roster of exclusive vehicles. Playground Games has packed the upcoming month with 10 free reward cars that you can earn entirely through gameplay over the next four weeks.

Because these event vehicles are time-limited and cannot be bought in the standard Autoshow, knowing exactly how to allocate your time is crucial. If you miss them now, you will be forced to hunt them down for millions of credits in the hyper-inflated Auction House or wait for them to hit the Horizon Backstage Pass.

This comprehensive, step-by-step unlock guide details the points requirements, weekly schedules, and optimization strategies to ensure you add all 10 Series 4 cars to your virtual garage.

The Month-Long Series 4 Milestones

These two heavy-hitters require a cumulative point total earned across all four weeks of the "Horizon Mascot Party" series. To track your progress, always check the leftmost tile on your Festival Playlist menu.

The Ultimate "Day One" Grinding Strategy

If you want to unlock the 1970 Honda N600 on the very first day of the update without pulling your hair out over difficult Unbeatable AI drivatars, utilize this exact menu strategy:

1. Knock Out Monthly Rivals First

Enter the two Monthly Rivals time-trials immediately. You do not need to set a world-record time-simply complete one clean lap without hitting the walls or missing a checkpoint. Doing this grants you 4 points toward every single week of the series instantly, giving you a massive 16-point head start before you even touch a seasonal race.

2. Pre-Build a B-Class Retro Rally Car

The Week 1 Summer trial is heavily rumored to feature restrictive dirt racing parameters. Save time on Thursday by building and tuning a 1998 Subaru Impreza 22B or a Mitsubishi Lancer Evolution VI tonight so you are ready to carry your online co-op team.

3. Monitor the Forzathon Shop

A major shop refresh will roll out alongside the "Mascot Party" theme. Keep an eye out for rare, wheelspin-exclusive vehicles that can be purchased using Forzathon points, which saves you from spending millions of credits on the secondary market.
