LFM (Low Fuel Motorsport) is an independent, free online racing platform for PC sims, widely used with Assetto Corsa Competizione. You sign up on its website with your Steam account, get your license, register for a scheduled race and join its server from the game. Races run on a fixed schedule, with skill-based matchmaking and two ratings: Elo (performance) and Safety Rating (clean driving). It’s not a Kunos or 505 Games service, and it doesn’t work on consoles.
What Low Fuel Motorsport is
Low Fuel Motorsport describes itself as an independent competitive sim racing platform. It works a lot like iRacing, but on games you already own: it runs seasons, cups and endurance races on fixed schedules, splits drivers into groups based on their skill level and keeps all your results on a public profile.
It started with Assetto Corsa Competizione, and ACC is still its main game. Over the years it has added other sims. According to announcements covered by specialist outlets, in 2026 it offers races for:
- Assetto Corsa Competizione (PC).
- Assetto Corsa, the original, through Content Manager.
- Assetto Corsa EVO, in beta since April 2026, with GT3, GT4 and MX-5 series.
- Automobilista 2, RaceRoom and Le Mans Ultimate.
It’s all on PC. The console versions of ACC (PS5, Xbox Series, PS4, Xbox One) can’t join LFM servers. If you play on console, check our guide to Assetto Corsa Competizione servers to see what options you have.
How to sign up for LFM
- Go to the official website, lowfuelmotorsport.com, and create your account by signing in with Steam. Linking Steam is mandatory because that’s how LFM identifies your driver on the servers.
- Complete your profile. Using your real name is recommended, as on other competitive platforms.
- Choose the sim you’re going to race in. Each game has its own Elo, its own license and its own calendar.
- Read the platform rules and accept them before signing up for your first race.
You need to own the game on Steam. LFM doesn’t sell or give away games.
How to race on LFM with Assetto Corsa Competizione
1. Build up your Safety Rating in ACC
LFM servers require a minimum level of ACC’s own Safety Rating (the one you see on your in-game driver profile). If it’s your first time online, unlock it first by racing on public servers or in quick races without crashing. According to the community, the minimum required is around 80 points, but check the exact value on the server page on LFM.
2. Get your license
In ACC, for your first license you have to pass a test on LFM’s license server: several consecutive valid laps (the community says seven) under a time limit, without going off or touching anyone. If you go off track or get penalized, the counter resets. The license can take a while to show up on your profile after you complete it.
3. Sign up for a race
On the website’s calendar you’ll see the available series (GT3 sprints, GT4, one-make cups, endurance, etc.). Some require a minimum license. Register for the session that suits you; slots are assigned to splits based on your Elo, so you race against people of a similar level.
4. Join the server from the game
Shortly before the start time, open ACC, go to multiplayer and find the LFM server for that race. The race page on the LFM website has the details you need to join. When you finish, the result is uploaded to your profile automatically and your Elo and Safety Rating are updated.
To be quick from the start, decent setups will help; we explain them in our guide to Assetto Corsa Competizione setups.
LFM with the original Assetto Corsa
LFM added the original Assetto Corsa in late 2023. Here the process is different because the platform works together with Content Manager, the community launcher. What you need:
- Assetto Corsa on Steam, ideally the Ultimate Edition, because many series use cars and tracks from the official DLC.
- Content Manager (the free version is fine).
- The Real Penalty mod, which handles penalties for contact and track limits.
- The car or track mods each series requires; LFM provides the links on the series page. Many drivers also use Sol or Pure for weather and lighting.
If it’s your first time with mods, follow our guide on how to install mods in Assetto Corsa first.
Licenses, Elo and Safety Rating
- Elo: measures your performance. Everyone starts with the same score, and it goes up or down depending on whether you finish ahead of or behind what was expected against your rivals.
- Safety Rating (SR): measures how cleanly you race. Contacts and off-tracks lower it; clean races raise it.
- Licenses: everyone starts as Rookie. To move up a class you need a minimum Elo, SR and number of races completed. Higher classes give access to more demanding series and splits.
The thresholds for each license change over time and depend on the sim, so check them on your LFM profile instead of relying on old tables.
Requirements and whether it’s free or paid
You need a PC with the sim purchased on Steam, a linked Steam account and a stable connection. A wheel isn’t mandatory, but it’s what most people use in this kind of racing.
Racing on LFM is free: there’s no fee to sign up for races. The platform is funded by voluntary donations, and there’s a paid support tier on Patreon (LFM Supporter) for anyone who wants to contribute, which adds perks to your profile. You don’t need it to compete.
Frequently asked questions
Is LFM free?
Yes. Signing up and racing cost nothing. You just need to own the game. The paid Patreon support is optional.
Can I use LFM on PS5 or Xbox?
No. LFM works with the PC versions linked to Steam. ACC players on console can’t join its servers.
Does LFM work with Assetto Corsa EVO?
Yes, in beta since April 2026, with GT3, GT4 and MX-5 series. During the beta, Safety Rating doesn’t apply to those races, and serious incidents are reported via Discord.
Why can’t I join the ACC license server?
The most common reason is that your ACC Safety Rating is still locked or below the minimum. Do a few clean races on public servers and try again.
Do I need the Assetto Corsa Ultimate Edition to race on LFM?
For the original Assetto Corsa, in practice yes: many series use cars and tracks from the official DLC, all of which come in the Ultimate Edition. For ACC you don’t need it; each series states whether it requires any DLC.
