A clean lap is a lap with no wall hits, no rewinds, and no corner cuts — and it's the only kind that counts on the Rivals leaderboard. That changes the answer to "what's the fastest car." Raw top speed doesn't matter if you can't keep the car on the racing line through the corners. Here's what actually posts the fastest clean times.
Top 5 Clean Lap Cars in FH6
| # | Car | Class | Strength | Best For |
|---|---|---|---|---|
| 1 | Mosler MT900S | S2 | Handling-to-speed ratio | Technical tracks |
| 2 | Rimac Nevera | S2 | 0-60 in 1.85s, AWD grip | Mixed tracks |
| 3 | Koenigsegg Jesko | X | 483+ km/h top speed | High-speed tracks |
| 4 | Bugatti Chiron Super Sport | S2 991 | 420 km/h + stability | Long straights |
| 5 | Hennessey Venom F5 | S2 990 | 400+ km/h + raw power | Power circuits |
1. Mosler MT900S — The Clean Lap King
The best clean lap car in FH6, full stop. It has the best handling-to-speed ratio in the game, which is exactly what clean laps reward. On a technical circuit with tight chicanes and off-camber corners, the MT900S carries more speed through the turn than any hypercar — and it's stable enough that you won't accidentally brush a wall and dirty the lap.
It won't win a drag race against the Jesko, but Rivals laps are decided in the corners. This is the car the top of the leaderboard is running on twisty tracks.
2. Rimac Nevera — Fastest Off the Line
The Rimac Nevera hits 60 mph in 1.85 seconds and its all-wheel drive puts the power down cleanly out of every corner. That launch makes it lethal on tracks with a lot of slow-speed exits — it simply gets back up to speed faster than anything else. On mixed tracks that mix tight sections with straights, this is the safest pick for a clean lap.
3. Koenigsegg Jesko — The Straight-Line Monster
The Jesko holds the FH6 top speed record at 483+ km/h. On high-speed circuits with long straights it's untouchable. The catch: that much power is hard to manage into tight corners, and a single oversteer moment dirties your lap. Use it on open, flowing tracks — avoid it on technical ones.
4. Bugatti Chiron Super Sport — Stable Speed
S2 991 rated, with 420 km/h top speed and the most stable high-speed cornering of the big-power hypercars. It's the forgiving alternative to the Jesko — a touch slower on the straights, but far less likely to bite you mid-corner.
5. Hennessey Venom F5 — Raw Power
S2 990, 400+ km/h. Pure straight-line muscle with enough handling to stay on the racing line if you're smooth. It rewards disciplined throttle control; if you mash the pedal out of corners it'll spin the rears and dirty your lap.
What Makes a Clean Lap Car
Three things separate clean-lap cars from drag cars:
- Cornering grip. The car has to hold its line through a corner at speed without sliding wide into a wall. This is why the Mosler beats the Jesko on technical tracks despite being slower on paper.
- Stability under braking. Clean laps die at the braking zone. A car that's twitchy under hard braking forces you to brake earlier, and every extra meter costs time.
- Predictable power delivery. You need to be able to get on the throttle early out of a corner without the rear stepping out. AWD cars (Rimac) and well-balanced ones (Mosler) have the edge here.
Track Type Cheat Sheet
Pick your car based on the circuit, not on a single "best" number:
- Tight / technical (lots of chicanes, hairpins) → Mosler MT900S
- Mixed (corners + straights) → Rimac Nevera
- High-speed / flowing (long straights) → Koenigsegg Jesko
Tuning Tips for Clean Laps
The stock car gets you 90% of the way there, but a few tuning tweaks shave real time off a clean lap:
- Brake balance — shift it slightly rearward (55-60% front) so the car settles instead of diving under hard braking.
- Tire pressure — run the lower end of the recommended range for more mechanical grip through corners.
- Downforce — max front and rear aero on technical tracks. You lose a little top speed, but the cornering gain is worth more on most circuits.
- Differential — for AWD cars like the Rimac, a slightly rear-biased torque split gives you better rotation into corners while keeping the launch grip.

Frequently Asked Questions
Quick answers to the most common clean-lap questions:
- What is the best clean lap car in FH6? The Mosler MT900S — best handling-to-speed ratio in the game.
- Is the Jesko good for clean laps? On high-speed tracks yes; on technical tracks it's hard to keep clean.
- What's the fastest Rivals car? Mosler on tight tracks, Rimac or Jesko on open tracks.
- What makes a lap "dirty"? Wall contact, rewinding, or cutting the track — all void the lap.
