forza-horizon-6-series-4-guide-how-to-unlock-all-10-reward-cars-master-the-edamame-circuit

Summary: The Horizon festival has officially received a massive injection of Japanese automotive subculture. Today, August 13, 2026, Playground Games officially unlocked the highly anticipated Series 4 "Mascot Party" update globally across Xbox and PC platforms. Moving away from standard retro rotations, this month-long festival playlist is entirely dedicated to the colorful, chaotic world of Japanese custom props, tight track engineering, and heavily requested modern and classic vehicles.

Running from August 13 until September 10, 2026, Series 4 challenges drivers to adapt to a completely overhauled map environment while fighting to unlock 10 rare festival exclusive vehicles. Whether you are a drift purist, a competitive hot-lapper, or an EventLab creator, this guide breaks down the core strategies to conquer the new playlist on Day 1.

The Stadium Overhaul: How to Conquer the "Edamame" Time Attack Circuit

The central Horizon Stadium has undergone its most radical transformation of the year, morphing into a permanent Japanese-inspired Time Attack Circuit. Named after the festival's new giant green soybean mascot, the track features narrow lanes, sharp chicanes, and tight elevation changes that punish heavy, high-horsepower drag builds.

Tactical Hot-Lap Strategy

To claim your clean times in the Monthly Rivals pool and win the weekly seasonal championships, dump your hypercars and focus heavily on lateral grip:

The Meta Class: A-Class (800) and S1-Class (900) are the absolute sweet spots for this circuit.

Tune Priority: Maximize downforce and tire width over raw top speed. Vehicles equipped with custom front splitters and race rear wings will maintain a stable line through the stadium's aggressive technical S-curves.

The Points Shortcut: Complete the Monthly Rivals challenge on the Edamame circuit during day one. Securing a single clean lap (without hitting walls or missing checkpoints) automatically awards 4 Points toward every single weekly season in Series 4, giving you an immediate head start.

Series 4 Reward Cars: The 10 Essential Unlocks

Series 4 introduces a balanced mix of nimble track weapons, pocket-sized classics, and brutal retro-modern powerhouses. The entire festival progression is anchored by two massive monthly point milestones, supplemented by weekly seasonal reward cars. Players looking to expand their garage alongside these Series 4 rewards can also explore Forza Horizon 6 Cars.

Overall Series Milestones

80 Points: 1970 Honda N600 - A legendary, ultra-light kei car making its triumphant festival return. It serves as the ultimate blank canvas for absurd high-RPM motorcycle engine swaps in the upgrade shop.

160 Points: 2021 Porsche 911 GT3 - The definitive modern track weapon, featuring a naturally aspirated flat-six engine and unparalleled mechanical grip straight out of the box.

Weekly Seasonal Highlights

Summer (August 13 - August 20): 2018 Exomotive Exocet Sport V8 XP-5 (20 Points) and the classic 1969 Datsun 2000 Roadster (40 Points).

Autumn (August 20 - August 27): 1992 Toyota Supra Twin Turbo (20 Points).

Winter (August 27 - September 3): 2023 Hyundai Ioniq 5 N (20 Points) - Bringing high-performance dual-motor EV tech to the festival streets.

Spring (September 3 - September 10): 2024 Ford Mustang Dark Horse (20 Points).

EventLab Upgrade: 47 New Japanese Mascot Props Unlocked

For the sandbox blueprint community, today's update drops a massive content patch into the EventLab toolkit. Creators now have access to 47 completely brand-new structural assets themed around Japanese street culture and festival branding.

These include giant inflatable curry rice mascots, neon-lit paddock barriers, mechanical mascot statues that react when cars drive past, and authentic roadside construction signage. These props can be layered seamlessly into custom blueprints to build highly detailed drift arenas or inner-city highway replicas.

Series 4 Patch Notes & Fixes

Alongside the new content, today's August 13 update deploys several critical stability and quality-of-life adjustments to the core engine:

Audio Enhancement: Retuned the exhaust notes for the Alfa Romeo Giulia Quadrifoglio and select Lamborghini V10 models, restoring their aggressive, high-revving engine depth.

Collision Optimization: Resolved clipping errors with the front bumpers on the Nissan Patrol and Lamborghini Huracán Tecnica when paired with widebody kits.

Garage Buffer: Fixed a lingering UI glitch where players with maxed-out garages would receive a "Garage Full" warning even after auctioning off vehicles.
