B class is the class I would send a new Forza Horizon 5 player to first. The cap is 700 PI, which is low enough that a stock supercar does not fit and high enough that a well built small car is properly quick. The racing is close, the cars are cheap, and a good build matters more than a rare car.
This page is the cars I would build for B700, for road and for dirt, and why they work. The car names, prices and the builds are the ones the community has settled on and that the tuning sites list; I checked them on 9 October 2026. The reasoning about why light front wheel drive cars win is mine, and it is the same reason it happens in a real one make series.
One thing to know first. Playground Games stopped making new series for Forza Horizon 5 after Series 43 in January 2025, when the Horizon Realms update and the PlayStation 5 version arrived. Since then the playlist repeats older series chosen by player vote. So the B class meta is fixed. What is fast today stays fast.
The best B class cars for road racing
| Car | Stock class | Why it works | Build cost with the car |
|---|---|---|---|
| 1974 Honda Civic RS | D | The lightest fast platform in the game. Engine swap, supercharger, widebody | about 85,500 CR |
| 1997 Honda Civic Type R | C | Same idea, newer chassis, less work to get to 700 | about 64,100 CR |
| 1990 Nissan Pulsar GTI-R | C | Four wheel drive, so it launches and puts power down out of slow corners | about 54,650 CR |
| 1968 Dodge Dart Hemi Super Stock | C | Big power for the PI, rear wheel drive, the fast car on long straights | about 386,850 CR |
| 1977 Holden Torana A9X | C | Rear wheel drive muscle that handles, a V10 swap gets it to 700 | about 231,600 CR |
The costs are Forzafire's totals for the car plus the full build. They move a little with the upgrades you choose.
1974 Honda Civic RS
The B class car. The community build starts with the 1.6 litre VVT engine swap, adds a centrifugal supercharger, the widebody kit, a race front bumper and a rear wing, race weight reduction, race anti roll bars front and rear, a race front differential and the exhaust and pistons, and lands on 700 PI at about 85,500 credits all in. The car itself is 25,000.
Why it works: PI is a formula, and a car this light scores well on handling and braking for very little of the budget, which leaves room for power. In the real world a 700 kg car with 200 horsepower beats a 1,400 kg car with 400 on any track with corners, and the game's PI calculation rewards the same thing.
The downside is the top speed. On the long highway sprints it gets caught. Pick it for the street and road circuits with corners.
1997 Honda Civic Type R
The same recipe on a better starting point: the EK9 Type R is already a C class car with a real chassis. It needs less to reach 700, so the build is cheaper, and the car is more forgiving on the limit than the 1974 car. If the Civic RS feels nervous to you, this is the one.
1990 Nissan Pulsar GTI-R
Four wheel drive, which the two Hondas are not. That matters in two places: the start, where it gets off the line ahead of everything, and wet or dirt sections in road races where the Hondas spin the inside wheel. The common build keeps the engine, or swaps to the 3.2 litre six, and spends on suspension, weight and the differentials for about 54,650 credits all in.
1968 Dodge Dart Hemi Super Stock
The expensive one and the straight line one. It is rear wheel drive with a big engine, so it reaches 700 PI with power rather than handling, and on the sprints with long straights it beats the Hondas. It is also the car that teaches you throttle control in B class, because it will spin the rears out of every slow corner if you are greedy. The build is the most expensive on the list, nearly 400,000 credits with the car, and that is the reason to build it second, not first.
1977 Holden Torana A9X
The Australian touring car. Rear wheel drive muscle that turns better than the Dart, and the community build uses the 8.4 litre V10 swap with nearly every engine upgrade and a full suspension and tyre set. About 231,600 credits all in. A good middle ground between the Civics and the Dart for circuits that mix corners and straights.
The best B class cars for dirt and cross country
| Car | Why it works | Build cost with the car |
|---|---|---|
| 1970 International Scout 800A | Short wheelbase, four wheel drive, light for a truck. The B class dirt car | about 96,600 CR |
| 1975 Ford Bronco | Same idea, a little bigger and more stable at speed | about 88,000 CR |
| 2017 Ram 2500 Power Wagon | Heavy, but it takes the hits in cross country and keeps its speed over the rough | about 115,100 CR |
| 1979 Toyota FJ40 | The cheapest to get going; slower than the Scout on the same build | about 108,500 CR |
| 2020 Ford F-450 Platinum | The one for cross country routes with big jumps and water, where mass helps | about 136,000 CR |
The Scout is the pick. On dirt the game rewards four wheel drive and a short wheelbase, because the routes are a chain of slides and the car that straightens up first wins. The big trucks are for cross country, where the route goes through rocks, fences and rivers and a light car gets thrown about.

How to build a B700 car
The rules that make every car above work, in the order I would spend the credits:
- Weight first. Race weight reduction is the best PI per credit in the game, and it makes the car better everywhere, not just faster.
- Tyres and suspension before power. Race tyres, race springs and anti roll bars. The PI cost is high for tyres, so on a light car go one step down on tyre compound and spend the PI on the engine instead.
- Power last, and only to fill the PI. Add engine parts until the car reads 700, then stop. A car at 695 is giving something away; a car that needs a part removed to fit the class has the wrong part.
- Differential. A race front differential on the front wheel drive cars is the difference between the inside wheel spinning and the car pulling out of the corner.
- Then tune. The build gets you to 700. The tune is where the Civic goes from quick to unbeatable. My how to tune cars in Forza Horizon 5 page is the long version.
One racer's note on all of this. In B class the field is close enough that the driver matters more than the car. If you lose to a Civic in your Civic, it is not the build.
B class or C class?
C class is the step down, 600 PI, and the same cars appear there with a smaller build. My best C class cars in Forza Horizon 5 page covers it. B class is the better place to learn, because the extra 100 PI goes into tyres and brakes and the cars stop behaving like road cars.
For the full roster, every car with its stock class is on the Forza Horizon 5 cars list.

601 to 700. Every car above is built to 700, the top of the class.
Is the Civic RS still the meta in 2026?
Yes. Forza Horizon 5 has not had a new series since January 2025, so nothing has changed the balance. The Civic RS, the Civic Type R and the Pulsar GTI-R are still the road cars to beat.
What is the best four wheel drive B class car?

From about 55,000 credits for the Pulsar to nearly 400,000 for the Dodge Dart, car included. The Civic RS is about 85,500.
Which B class car is fastest in a straight line?
The 1968 Dodge Dart Hemi Super Stock, built with power rather than handling. It gives that back in the corners.
