Column: Why Karting Isn’t Succeeding in Sim Racing

Karting is the first rung on the motorsport ladder, so why is it so hard to accurately replicate within sim racing? With endless amounts of circuit and kart combinations, why is karting so difficult to simulate?

Two approaches to karting dominate the sport in the world of sim racing. Assetto Corsa's mods have the advantage of volume of content which is to be expected, and dedicated karting sims like KartSim, KartKraft and Kart Racing Pro are designed purely around the idea of karting simulation. KartSim is a DLC pack for Studio 397's rFactor 2 which sets it aside from the other two offerings in terms of a pure karting simulation.

These kart titles are aimed more towards karting hobbyists and professionals than the average sim racer. This demographic makes use of companies such as Next Level Racing which offer entire cockpits dedicated to karting. An investment the average sim racer most likely can not justify in 2024.

But are these cockpits worth investing in? Karting is one of the most physical forms of motorsport, so why can it not be simulated realistically? We will hear from ex-Top Gear stig, Ben Collins, on his opinions on karting simulations and delve into some options for you to try from your rig or desk.

Can You Accurately Simulate Karting?​

As previously mentioned, karting is one of the most physical forms of motorsport. Driver weight transfer and movement are key to success when finding that extra tenth of a second on your competition. Simulating that physicality is impossible, especially if you are using a karting rig that doesn't support many of the motion devices found on bigger rigs used to simulate cars.

Karting has always been a bit of a black sheep in the sim racing community. A lot of people's rigs are not set up to suit a karting seating position and that ruins their immersion. As well as people's rigs not being up to the task, outside of Automobilista 2 and Assetto Corsa mods, the karting offerings in the mainstream sim racing titles are lacklustre at best.

To be clear, the ability to simulate a karting race is of course possible, as mentioned there are dedicated titles to the discipline. However, to accurately depict how a kart feels, handles and behaves is nearly impossible without a seriously complex motion setup.

"Some things are much harder to get right than others, for example go-karting. Nobody should bother. It is impossible to replicate a two-stroke go-kart right now" Ben Collins, ex-BBC Top Gear Stig and decorated racing driver talking to Michel for OverTake.gg at Silverstone earlier this year.

Assetto Corsa Karting​

One title that stands aside from the rest of the karting offerings in sim racing is Assetto Corsa. Like with the rest of the catalogue in Kunos' much-loved simulator, the quality of the third-party karting content can range dramatically. Be aware of this when downloading tracks and karts. You can not expect them all to be up to first-party content level.

Your options here on OverTake.gg are plentiful. You can drive everything from the common Sodi rental karts that are present at nearly every single indoor and outdoor karting centre, right up to the incredibly fast 125cc shifter karts. All for free.

GoKart 0.3a - rex1825

The original kart mod for Assetto Corsa, this mod came out in October 2014. Two months before Assetto Corsa was officially launched out of early access in December of that year.


This mod is therefore a bit out of date and certainly has quirks. However, the raw and simplified feeling of an early Assetto Corsa mod is still amazing fun if you don't look into it too far. Rex1825's creation laid the groundwork for the following two kart mods that have been so successful.

GoKart 50ccm - 13bhp/11NM, 70kg, ~105km/h
GoKart 100ccm - 22bhp/15NM, 71kg, ~125km/h
GoKart 125ccm - 31bhp/21NM, 71kg, ~140km/h
GoKart 125ccm Shifter - 41bhp/28NM (Turbo), 74kg, ~155km/h, 6-speed


GoKart 0.5c - Cercata

The second mod in this mini-list takes from the previous iteration of the go-kart mod and evolves it into a much more modern offering. A thorough overhaul of the kart's physics, liveries and model makes this a huge step towards modernizing Assetto Corsa's karting offering.


For messing around and racing on the tight and twisty circuits, this mod is really hard to beat. The scale of engines and variety of karts is also superb.


  • 270cc -> 8bhp, 150kg
  • 390cc -> 12bhp, 150kg
  • 250cc -> 28bhp, 143kg
  • 50cc -> 13bhp, 70kg
  • 100cc -> 22bhp, 71kg
  • 125cc -> 31bhp, 71kg
  • 125cc shitfer turbo -> 41(28)bhp, 74kg
  • 125cc shifter SGM -> 48bph, 74kg

Sodikart Sodi RT10 - alpadev

My personal choice and a community favourite as well. A fantastic mod created as an evolution of the previous two karts listed. The Sodikart RT10 is the pinnacle of rental karting. If you have ever driven a go-kart, it's probably been this kart!

This kart holds a special place in my heart because, In a previous life, I used to service these karts and marshall at a circuit for the British public in all weathers. Driving this kart in Assetto Corsa brings back memories and is surprisingly accurate when you take the physical forces out of the equation.

Karting is such a crucial stage in a racing driver's career. It teaches and punishes drivers early on with its physicality and close racing. It is a shame that karting in sim racing doesn't quite match the level of ingenuity that real karting has. In the future, there are bound to be revelations. However, until that day comes karting is stuck and plateauing in terms of realistic simulation and player numbers.

Where is the UK kart track pack? I've found the Kartsim package and then the euro track pack but that doesn't tally up to 41 kart tracks, I've only gone and looked as that piqued my interest and I was going to purchase.

£899

kartsim is the best and complete kart sim game ever made, with the best of ISI physics in rF2.
The best money invested for my simucube 2, with AI, night, rain, it's so complete, with so much content, I dont master all the tracks at all, the learning curve is abyssal :), Im ready to spend any money for each complete game with this quality, rF2, LMU, the best of the best ;)

Damn, I just checked out their Forest Edge (where I used to race a few years back)... That looks nothing like it AT ALL. Yikes.

if you learn the curves, they are exactly the same, you can race with the closed eyes, and dont see the forest ;)

What do you mean? A mini is lifting rear wheels when cornering hard? What is the difference with a kart then? Or do you mean in a kart the driver causes this with his body and in a mini it is the mini itself who causes it?

Not sure what you want me to say.
Karts lift rear wheels is basic concept in their cornering.
Mini does this with skill of the driver.
My only point was it's a great track day car.
 
I should make a 750-horsepower mod for the rental kart in AMS1. NASKART!

It's more the elevation changes, the off camber/on camber, the BIG bumps that you have to navigate. I'm not asking you to watch a whole video of me practicing there, but just check out 1-2 laps. The KartSim track is flat as a pancake - Forest Edge ain't flat, I've broken my ribs there twice from the bumps simply getting knocked around in my seat as you do!

A race mini can do that because the rear axel is so stiff, many FWD race cars can be set up to do that, it doesn't have anything to do with driver skill, a driver can't make a race car do that unless a race CAN do that.
That ain't happening in an F1 car regardless of 'skill'.

In cornering if you imagine the rear is very soft the wheel would not be lifting it would be on the ground but the car body would still be in the same position. with stiff rear the wheel is following the body.

Example......... stiffen the rear alot and the wheel would be off the ground... no driver skills involved...

Some hours spent in karting in Automobilista 1 in time trial... Realistic or not, it's a lot of fun and helps you to constantly push your limits, you learn a lot. One of my favorite series.;)

yeah some tracks are better made than others, you have 41 tracks, you can try some others
 



it's not as bad as you say, and with a lower camera on Katsim, I have almost the same feeling ;), Im really impressed by the work;)


it's so accurate ;)

Ok, well I've actually driven it, so what may appear to be accurate looking at VIDEOS and you playing it on a computer game I can tell you it's not accurate. However, having seen how you interact with others on this site I know you do like a good troll job, so I'll leave you in your own little world on this one - if you THINK it's accurate, more power to you.

Glad you spent almost £1000 on computer game tracks... More money than sense springs to mind.

I have spent almost 2000€ for 10 laps on nordschleife with a BMW M2 last week ;), when money is more than mind you are happy ;)

Well.. putting aside that I have made a few karts tracks, I find it enjoyable to do karting in sim racing when pairing up with VR.
there are nice offerings, like the one mentioned in this article for AC, there are the kart models in AMS1 or even a shifter model for rF2 available here in race department also.
Karting in VR fels visceral and engrossing if you setup challenging Ai that also drive dirt and rF2 excels at this< and thats my go to sim for karting.
 
Only scenario I can think of is when you're very serious with karting and want to familiarise yourself with specific tracks. In all other cases either go karting for real or simulate something more exciting (personal opinion).
