FH6 vs FH5 Detailed Comparison — What's Actually Different
Forza Horizon 5 launched in November 2021 and received three years of content updates across 40 series. Forza Horizon 6 is a new game built on an updated version of the ForzaTech engine, not an expansion — and Playground Games rebuilt several core systems rather than iterating. This comparison is based on the FH6 launch build versus FH5's final update (Series 40). No speculation. Just what is actually in the game right now.

Map: Size, Biomes, Road Network
FH6 map size: Approximately 125 km squared of drivable area, compared to FH5's 107 km squared. That is a 17% increase in raw area, but raw area is the wrong metric to focus on — road density and biome diversity matter more for how the map feels.
Road network: FH6 has approximately 640 km of roads versus FH5's 580 km. The road density is higher because FH6's map has more urban area — dense city streets add road distance without adding much map area. FH5's Mexico had wide-open desert and jungle sections with few roads. FH6 trades some open space for denser road networks, and players who prefer technical driving and urban street racing will notice the difference immediately.
Biomes: FH5 had 11 biomes (jungle, desert, swamp, canyon, tropical coast, farmland, volcano, living desert, rocky coast, arid hills, and the city of Guanajuato). FH6 expands to 14 biomes with the additions of dense urban metropolitan, alpine snow fields, temperate rainforest, and autumn hardwood forest, while dropping the living desert and arid hills. The alpine snow biome is the biggest win — FH5 had only the top of the volcano with snow. FH6's alpine region is approximately 15 km squared of snow-covered roads and terrain, roughly 12% of the total map. The dense urban biome is the second biggest upgrade: FH5 had Guanajuato, a small hillside town with tight streets. FH6's city biome is a proper metropolitan area with highways, overpasses, tunnels, and surface streets — closer to FH3's Surfer's Paradise in scale and complexity.
Elevation: FH5's volcano was the highest point at approximately 1,800 meters with a road to the summit. FH6's mountain range peaks at approximately 2,200 meters with a winding 12 km road that gains 1,500 meters of elevation — a proper hill climb route. The elevation variation across the entire FH6 map is greater, which makes the map feel larger because you are frequently going up or down rather than traversing relatively flat terrain.
Car List
FH5 launch car count: 526 vehicles. After three years of updates (car pass, seasonal rewards, DLC packs), FH5 ended with 716 vehicles. FH6 launch car count: 821 vehicles. FH6 launches with 105 more cars than FH5 ended with, and 295 more than FH5 launched with. This is the largest launch car list in Horizon series history.
New manufacturers: FH6 adds Rimac, Gordon Murray Automotive, Cupra, and several Chinese manufacturers (NIO, XPeng, BYD) that were absent from FH5. The Chinese EV additions are notable — FH5 had minimal Chinese representation. The Rimac Nevera's inclusion is significant because it fills the electric hypercar slot that FH5 never properly addressed.
Notable new cars: Koenigsegg Jesko Absolut, Hennessey Venom F5, Rimac Nevera, Gordon Murray T.50, Bugatti Bolide, Porsche 911 GT3 RS (992), Lamborghini Revuelto, Ferrari Daytona SP3, McLaren Artura, Audi RS e-tron GT. The hypercar category alone gained 23 new models at launch.
Vehicle categories: FH6 adds two new vehicle categories — Hyper EVs and Track Toys — splitting what was a catch-all Extreme Track Toys category in FH5 into more specific groups. This matters for car restriction filters in events and for drag racing class restrictions.
Cars that did not carry over: Approximately 40 FH5 cars did not carry over to FH6 due to licensing expirations, mostly from small European manufacturers (Spyker, Wiesmann, some Alfa Romeo models). The Mitsubishi Lancer Evolution VIII and IX returned after being absent from FH5's launch. All cars that were in FH5's final build and still under active license are in FH6's launch build.
Graphics and Performance
Global illumination: FH6 replaces FH5's baked static global illumination with a real-time system. In FH5, lighting was pre-calculated for fixed time-of-day positions and interpolated between them. In FH6, light bounces are calculated in real time, which means reflections update continuously as the sun moves — no more reflection snapping when the time-of-day transitions between pre-baked states. The visual difference is most noticeable during sunrise and sunset transitions.
Car paint rendering: FH6 adds a clear-coat layer to all car paints. FH5 rendered paint as a single-layer shader with metallic flake, color, and gloss combined. FH6 separates these: a base color layer, a metallic flake layer suspended above it, and a clear-coat layer on top that catches specular highlights independently. Car paint in FH6 looks deeper and reflects light more accurately, especially on metallic and pearl finishes. This is visible in the FH6 photo mode where darker colors and pearlescent paints show more depth than FH5 equivalents.
Performance targets: FH6 targets the same frame rates as FH5 on equivalent hardware — 4K/30 on Series X in quality mode, 4K/60 in performance mode. Series S targets 1080p/60. The new global illumination has a performance cost, so 60 FPS mode uses a slightly reduced ray count compared to 30 FPS quality mode. On PC, global illumination quality scales from Low (baked) to Ultra (full real-time).
Physics Engine: The Biggest Under-the-Hood Change
FH6's physics changes are the most substantial upgrade and the hardest to communicate because they are feel changes, not feature bullet points.
Suspension model: FH5 used a simplified linear spring-damper model — compress the spring 50%, get 50% of the spring force. FH6 uses a progressive suspension model where spring force increases non-linearly with compression. This means cars handle curbs and bumps differently: a FH5 car hitting a curb would react with a sharp, linear jolt. A FH6 car hitting the same curb absorbs the initial impact progressively, which feels more natural through controller force feedback. This is most noticeable on rally and cross-country events where cars are constantly dealing with surface irregularities.
Tire heat model: FH6 adds tire heat simulation. Tires start cold and grip improves over the first lap or roughly 1-2 minutes of driving as they warm up. Once warm, grip stays consistent. This affects drag racing (cold tires = less launch grip), track racing (first-lap grip is lower), and drift builds (cold tires are easier to break loose). FH5 had a static tire grip model with no temperature variable. This is a meaningful change for competitive players who will now need to warm up tires before record attempts.
Aerodynamic drag curve: FH6 models a more realistic drag curve above 200 mph. In FH5, aerodynamic drag increased approximately linearly with speed. In FH6, drag increases exponentially above 200 mph — this matches real aerodynamic behavior. Top speed builds in FH6 are generally 5-15 mph slower than equivalent builds in FH5. Cars that hit 300 mph in FH5 without much effort might top out at 285-295 mph in FH6. See the FH6 fastest cars list for updated speed numbers.
Game Modes and Features
EventLab: FH6's EventLab is the single biggest feature upgrade. FH5's EventLab had a 500-object budget, no visual scripting, limited prop snapping, and no prefab system. FH6 adds Rules of Play visual scripting with triggers and actions, 750-object budget, prop-to-prop snapping, saved prefabs, and terrain deformation tools. Any FH5 custom event is recreatable in FH6 with more fidelity. The reverse is not true. For a full guide, see the FH6 EventLab creator guide.
Multiplayer: FH6 adds dedicated drag racing lobbies with Christmas tree starts and electronic timing, a Team Festival Battle mode where two teams compete across multiple event types to control festival sites on the map, and reworked convoy stability with fewer disconnects when transitioning between events. FH5's multiplayer was stable but basic in structure.
Single-player content: FH5 launched with roughly 320 hours of single-player content if you completed every event, story, showcase, and accolade. FH6 launches with approximately 280 hours of single-player content. The 40-hour difference is primarily because FH5 accumulated expeditions and stories over multiple updates. FH6 will presumably catch up within the first 6-12 months of post-launch content.
Verdict: Should You Upgrade?
If you have put 200+ hours into FH5, completed most of the content, and want a new map, new cars, and updated physics: the upgrade is clearly worth full price. The map variety (urban + snow + autumn forests), the 130+ new cars, and the physics improvements are substantial.
If you are a casual player who has not finished FH5's campaign: wait for a sale. FH5 is still an excellent game with a complete content library. FH6 will be better a year from now with more cars, stories, and EventLab community creations.
If you primarily play competitive multiplayer: the player base will migrate to FH6 within the first month. FH5 lobbies will thin out. For active PvP, you need FH6.
