S1 class is the absolute sweet spot in Forza Horizon 6. It is fast enough to give you a genuine rush down the highways, but tight enough that you can actually attack Japan’s narrow roads and sharp corners without flying face-first into a guardrail.
If you want to dominate online lobbies or clean up street rivals, you can't just pick a cool-looking supercar and hope for the best. You need cars that maximize the 900 PI (Performance Index) cap.
1. The All-Rounder Powerhouse: 2024 Nissan GT-R NISMO
If you are attacking the street scene, the 2024 Nissan GT-R NISMO is arguably the most reliable weapon in the S1 bracket right now. It costs 270,000 CR at the Autoshow, or you can unlock it via the Touge & Street Rivals Collection Journal.
Stock PI: S1 730 | Speed: 7.6 | Acceleration: 9.5 | Launch: 10.0
Why it dominates: The factory twin-turbo V6 pushes roughly 600 hp, paired with Nissan's legendary ATTESA E-TS all-wheel-drive system. Out of the box, its launch stat sits at a perfect 10.0.
The Math: When tuned up to the absolute edge of S1 900, its 0–60 mph sprint drops down to a blistering 2.2 seconds. On tighter street races with red flare checkpoints, that instant traction off the line allows you to break away from rear-wheel-drive competitors before they can even stop spinning their tires.
2. The Handling King: Porsche 911 GT1 Road Car
When a race moves away from wide highways and into highly technical tarmac circuits, raw horsepower loses its value. You need corner speed. That is where the Porsche 911 GT1 Road Car comes in.
Why it dominates: This is a late-1990s Le Mans racing machine built for the street to satisfy homologation rules. It features a 3.2L twin-turbo flat-six producing roughly 544 hp in stock form, but its real secret is its physical shape.
The Math: The car uses a full ground-effect aerodynamic package. In S1 class, where downforce limits are highly contested, this car clings to asphalt like glue. In lateral G-force tests on technical circuits, it can hold lines at speeds 10–15 mph faster than standard sports cars, making it an absolute monster for setting leaderboard lap times.
3. The Dirt & Mixed-Surface Option: 2022 Subaru BRZ Forza Edition
You cannot talk about S1 meta without handling the rougher terrain. Found near the Sotoyama Ski Resort, the 2022 Subaru BRZ Forza Edition has quickly become the go-to platform for dirt racing and cross-country events.
Why it dominates: While the base BRZ is a lightweight A-class sports car, the Forza Edition completely rebuilds the suspension geometry and tire physics, turning it into an aggressive, wide-body rally hybrid.
The Math: Tuned to S1, it manages to maintain an off-road rating above 8.0 while preserving sharp tarmac handling. This versatility is vital for mixed-surface Scramble events where you spend 60% of the race on dirt and 40% on solid asphalt.
Smart Inventory Management
Building a competitive garage for every single race type gets expensive quickly. Upgrading three or four cars to competitive S1 builds easily runs past 1,000,000 CR once you factor in engine swaps, race platforms, and specialized tire compounds.
To bypass the long grind of repeating campaign events, smart players often look for external shortcuts. Platforms like U4N provide a quick workaround by offering
cheap forza horizon credits, allowing you to instantly buy the necessary parts, test multiple tuning setups, and unlock high-tier vehicles from the Auction House without spending dozens of hours farming skill points.
4. The Accessible Edge: Ferrari 488 Pista
If you are just stepping up from A class and want something forgiving yet incredibly fast, the 2019 Ferrari 488 Pista is the ideal entry point. It costs 260,000 CR in the Autoshow.
Stock PI: S1 765 | 0–60 mph: 2.85 seconds | Horsepower: 710 bhp
Why it dominates: Unlike mid-engine track cars that try to snap their rear ends loose when you apply throttle early, the 488 Pista is incredibly progressive.
The Math: With 710 horsepower moving a chassis that weighs just under 3,000 lbs, its power-to-weight ratio is elite for the class. It doesn't feature the extreme 800 kg downforce of a McLaren Senna, but its mid-engine balance means you don't need a professional racing line to keep it on the road. It handles mistakes cleanly, making it a highly reliable pick for online multiplayer lobbies where race traffic gets chaotic.
