(Almost) Everything EV\Electric Karting

Good skills & nice drive. My opinion is E-karting is a solution looking for a problem. There is little on the emissions side to be gained when compared to the world.

Karting at its root is supposed to be the most accessible form of motorsport. The FIA could use a reality check between this and their rear wheel protection. We need to encourage and remove barriers for participants at the lowest levels to aid with growing the sport. To me the tech is not there yet. The E class at rotax grand finals is a joke, no kart should weigh 500lbs

My main concern stems from the inevitable mandating of EVs which I believe is the true reason for all of this being introduced in the first place.

This is all a bunch of nonsense to push the green energy scam. I don’t like it and I don’t support it. It represents one step closer to autonomous vehicles and the outright ban of private vehicle ownership. Green energy and EVs are a bridge to no where.

I know way too much about the larger push for these kinds of technologies than to get on board with any of it. Mark my words, you all think I’m joking, the next step will be autonomous karting leagues and then the discussion of banning private vehicle ownership entirely.

It’s 2-strokes and gasoline for me or I don’t want any part of it. All of this represents the total neutering of this sport (batteries mean changing voltage curves which is traction control. You want to do that, go right ahead. That’s playstation. Not driving) and vehicles in the larger sense of freedom and choice. Maybe next we can mandate traction control, ABS, wheel covers on all 4 corners, titanium chain guards, 16 cameras to monitor driver biometrics, and driving suits with mandatory air bags.

What is this sport / hobby becoming? It’s all computer controlled safety monitored nonsense lol.

I’m moving to the Isle of Mann :rofl:

Get this crap out of karting.

Interesting video about EV production pertaining to the larger discussion:

Fair point. Karts in ethos should be light weight.

I do have to push back a little on the view this is a “solution looking for a problem”.

Personally, I’d be happy to navigate battery charging to avoid mixing fuels, spark plugs, changing jets, oiling air filters and tuning carbs.

If this potentially means better parity as well - then sure, that too.

I’ve driven electric rentals, which were impressive.

As James McMahon said, these homologations are not specified as replacing or taking away anything currently existing.

They are trying to create a framework for e-karting to exist. If the small few who try it can be a test case for the rest of us, then why not

Yep like I have been saying its just another choice for people who like electric karts. Why not just let it grow. If it becomes a big thing. It just helps karting get out there and grow.. If you don’t like it then its not for you.. But there are alot that do like it.. Coming from electric rental karting.. Keep going FIA just start talking to some of the electric kart manufactures before making all your rules to see if the Technology is there to make mandates on some of the rules..

I just hope my social credit score will be high enough that they allow me to use the highest power level on the mandatory eKart in 20 years… But it will probably void my insurance policy, so I’ll have to go back to underground petrol karting in parking garage basements to hide from the enforcement drones.

The infrastructure in all cases of gas vs. electric has been smashing the square peg into the circle. You can’t expect a track to invest in charging stalls, unless they are renting out the karts. I just don’t see at the club level this is working. Arrive and Drive works great that would be the best bet for maunfacturers.

It is not really the charging stalls the issue, but the grid capacity to provide the necessary power, which is not able to do (One of the main reason you dont see fast charging and many rentals being used at the same time). And the bigger the track, the bigger groups it needs in it rental sessions to be profitable, the more charging it will require.
It would be the same issue for competitive eKarts as well.

The solution is that the energy is provided directly by the track, either by using a diesel generator (which is as costly as using ICE karts) or using solar panels which requires a massive investment, free space and recurring costs of maintenance.

For the track management, the issue is not the runtime to be fair, but the charging time and capacity. So unless we finally see some tailored solution for karting (and not some standard Li-Ion - brushless motor), eKart is usable only indoors (and still struggles to convert a lot of facilities due to its current challenges)

What is the point of autonomous karting leagues? And if that sort of thing has already failed to gain ground in full-size racing (the AI cars that crash each other and stall), how is it going to trickle down to karting in a meaningful way? It’s antithetical to karting. Cars at least have an engineering and technology angle to justify pursuing self-driving technologies. Karts are supposed to stay simple.

For a country that is fully dependent on automotive technology, I can’t see us banning vehicle ownership any time in the near future. The auto industry is massive and it isn’t going away.

EV mandates aren’t coming soon either. All car companies that have said “we are going full EV in the next 10 years” have now backtracked on that and are switching back to combustion engines and research into alternative/synthetic fuels.

This sounds very alarmist. And I’m not sure how green energy is a “bridge to nowhere”. Resources are finite and we will need to use alternative sources eventually. Unless the inevitable heat death of the universe gets us first.

Show me where the EV industry hurt you Jim. :rofl:

EV was always supposed to be a transitional solution towards clean fuels. Synthetic fuels seem to be the way right now but we’ll see.

But EV poses too many political, economical and environmental issues to be viable at scale

There’s such a significant misunderstanding of how electric grids work in this thread that it hurts my head.

But I do agree that club owned kart tracks for owner racers will not be moving to electric karting anytime soon. For a business, it makes a lot of sense. Capital expenditure is easier to get hold off and the long term maintenance costs are significantly less. Add the reduced requirements for ventilations, fire protection and noise permitting and increases the interest. Which is why we are seeing the rise of electric rental karts.

Club owned kart tracks however are typically cash strapped, many don’t have any electricity on site at all, and they are often not in an urban area so extra load will be difficult and expensive to come across. Additionally the on going savings aren’t felt by the club, but by the kart users, and only if they (the users) can afford the capital outlay to buy what will be a more expensive electric kart.

Should the FIA come up with a set of rules, sure why not. It gives people something to aim for. I do think part of the reason they’ve mandated the battery in that location is make sure it’s unachievable anytime soon but I don’t really care. FIA karting has somewhat lost its relevance to me.

Ok, scaremongering:

1: It’s true that grid capacity and charging infrastructure are current constraints — but these are transient engineering challenges, not fundamental limitations of electric karting. Many industries (EV fleets, logistics hubs, construction sites) face identical issues and are already deploying scalable solutions like load balancing, local energy storage, and phased grid upgrades. This is no different to moving from horses to cars (but there’s no gas stations! we must stay on horses).

2: When cars first emerged in the late 1800s, electric vehicles were actually the dominant technology — quieter, cleaner, and easier to operate than gasoline cars, especially in cities. By the early 1900s, most taxis in New York were electric. What changed wasn’t technology, but economics and influence: the discovery of cheap Texas oil, the rise of mass-produced internal-combustion engines, and the lobbying power of the growing oil and automotive industries. As infrastructure like gas stations spread and marketing painted gasoline as “freedom,” electric vehicles were pushed aside. In a way, the EV revolution we’re seeing now isn’t new — it’s a return to the path we started on before the fossil-fuel era took over.

3: One of the biggest misconceptions about EVs is that they “overload the grid.” In reality, most charging happens when demand is lowest — late at night or during off-peak hours when homes, businesses, and industry use far less power. Utilities actually encourage this with time-of-use rates that make overnight charging cheaper, flattening the daily demand curve instead of spiking it. As smart chargers and vehicle-to-grid systems become common, EVs will increasingly act as flexible storage, helping stabilize the grid rather than strain it. Far from being a threat to grid capacity, widespread EV adoption can actually make the power system more efficient and resilient.

4: Electric vehicles are far more efficient than gasoline cars, converting about 85–90% of their energy into motion compared to only 20–25% for internal combustion engines, which waste most of their energy as heat. Even when accounting for electricity generation and battery manufacturing, EVs still produce substantially fewer lifetime emissions, and that gap keeps widening as the power grid adds more renewables. While it’s true that lithium and metal mining for batteries has environmental impacts, modern chemistries like LFP eliminate the need for cobalt, and recycling programs are already recovering over 90% of key materials. Unlike burning fuel — which releases carbon permanently — battery materials can be reused again and again, making EVs part of a circular, low-carbon system rather than a one-way drain on the planet’s resources.

5: The recent slowdown in EV policies and automaker transition plans isn’t a rejection of electrification — it’s the result of a complex mix of technical, economic, and political forces that differ across regions. In Europe, strong emissions laws and high fuel costs keep EV adoption moving forward despite subsidy reductions. China continues to surge ahead through heavy state investment and control of the battery supply chain. But in North America, the industry is far more politically reactive: many automakers appear to pander to whichever administration is in power, accelerating electrification when incentives and mandates are strong, then retreating toward hybrids or lobbying for tariff protection when political support shifts. The landscape changes every few years — and companies like GM, Ford, and Stellantis are constantly repositioning to align with policy winds rather than long-term climate goals. What looks like hesitation is really a strategic recalibration within a volatile policy environment, as the global industry catches its breath to balance technology, infrastructure, and political realities so the next wave of EV adoption is truly sustainable and economically grounded.

Lots of points to debrief there (to which I will come back to), but while the electric motor itself is a lot more efficient, the battery a lot less energy dense

This is true.

Gasoline is still far more energy-dense than current EV batteries — there’s about 12 kWh of energy per kilogram for gasoline compared with only about 0.15–0.27 kWh/kg for a typical lithium-ion automotive pack. On a volume basis, gasoline stores around 9 kWh per litre, while an EV battery sits closer to 0.3–0.4 kWh/L, meaning fuel holds about 20–80 times more energy depending on whether you compare by volume or mass.

But, EV drivetrains convert 80–90 % of their stored energy into motion versus only 20–30 % for a combustion engine, so the real-world range gap isn’t nearly as dramatic as the raw numbers suggest. There’s no getting away from gasoline being an unmatched energy carrier, but EVs make up the difference through far higher efficiency and regenerative braking, which is why a 60–80 kWh battery can deliver a range similar to 40–60 litres of fuel.

Beyond efficiency, EVs offer several other advantages that offset gasoline’s superior energy density. Electric drivetrains deliver instant torque, smoother power delivery, and lower maintenance, since there are no oil changes, spark plugs, or complex transmissions.

Add to this that gasoline engine technology has largely plateaued, with modern internal combustion engines already squeezing out close to their theoretical limits — around 40–45% peak thermal efficiency in the best designs (F1 engines). Further gains are marginal and come at the cost of complexity, emissions challenges, and diminishing returns. In contrast, EV battery development is still on a steep growth curve. Energy density has roughly doubled over the past decade, and new chemistries like solid-state, lithium metal, and sodium-ion promise significant improvements in capacity, charging speed, and cost. Manufacturing efficiency, recycling processes, and power electronics are also advancing rapidly, meaning each new EV generation delivers more range and performance from less material. Where combustion engines are refining a mature technology, electric mobility is still evolving through innovation, making it reasonable to expect continued leaps in capability and affordability — while ICE vehicles edge closer to their natural ceiling.

I have debated this subject with alot of people on here . And knew people would start jumping all over gas vs electric . Why not just let electric karts be a part of the whole karting community and enjoy the same sport as gas people. Just in a different kind of propulsion than gas. And those who dont like it dont have to enter that class.. Nobody is making you run them. Its just a choice. And not make it a EV this and that. There does not take a whole electric grid at a track to charge these batteries . You can bring them along with you as a battery swap. And alot of new pickup trucks and Cyber Trucks can charge them.

Welcome back Tanguy and others to the subject.. Its not about Ev this or that . Its about a class of race karts that want to run too in karting other than just gas karts …

One of the chief appeals of karting for many (though seemingly diminishing with the lack of shop classes, etc.) is the tinkering factor with petrol-based karting. Unless you’re going to tackle the morass of building custom electric motors and ESCs, it will be a spec unit, untamperable. And in that, a whole swath of interest disappears. ESCs will be ‘grid-swappable’ to prevent cheating, ditto batteries, and possibly even motors…

The engineer in me (that also enjoys racing r/c cars, slot cars, etc.) sees the branch of eKarting as its’ own interesting derivative. But it will kill part of what makes karting fun in the first place – an intentionally simple mechanical pursuit of speed. These vehicles were invented to do away with the hassle of full-size sportscar racing. To modify them into another complex system is to ignore the point and appeal.

KKS – keep karting simple.

ADDENDUM – where an eKart makes the most sense is actually in the kid-kart segment, where a spec low-hassle low-noise kart would be a positive introduction. And the lower energy demands would make it easier to achieve…

I think you were correct 20 years ago. But with all these spec classes the tinkering has become a solely chassis thing which would continue in an electric only environment.

Combine that with an apparent general reluctance to tinker with most people seemingly wanting something they can buy, use and throw away. People don’t tend to tinker with modern cars anymore (alot of which is due to manufacturers designing the opportunity to tinker out).

I agree that any ekarting class would be untamperable. Not sure if thats a good thing or not.

But wouldn’t electric karting be simpler then mechanical karting? It might seem more complex because its electrons and code, but thats only because we’ve become use to the complexity of combustion and chemistry inherent in internal combustion engines in karting. I could see a world where we change from:

  • Its not picking up well at the bottom end, i need to change the needle.
    To
  • Its not picking up well at the bottom end, i need to modify the torque curve, which could be made as simple and dragging a line on a computer screen or pressing a button for a preset curve on the dash.

Well articulated summary from NikG on the EV industry in both posts, with balanced views on the pros and cons.

I notice a lot of people enjoy the tinkering aspect of the sport. Does mechanical skill need to be a requirement to participate, though?

I think Ted’s hit on a good point that a 60V package could help broaden the entry funnel for families not willing/capable to keep up with the maintenance of engine karting at that level.

On a different note, and this is may not necessarily be valid, but i personally know someone who got his kid into cheap tin-tops instead of karting to protect his kid from inhaling exhaust gases. So there’s that too.

Good replies and the final remark had me laughing out loud. Let me sit down on the sofa in a reclined position and tell you about the Tesla in my closet that haunts me at night. :rofl:

Joking aside, I actually did work for the company for a while and I lasted about 6 months before I quit. If you’re a car guy and you’ve ever worked in a shop, the way they organize their parts is insane. Lack of logic is not something my brain can handle.

The bridge to nowhere comes from being around my father who is a planetary geologist of 65+ years. We have a lot of oil that we are not being allowed to use. We have a lot of natural resources. I can go into a lot of detail about this subject, but won’t bore people too much here. He has the most accurate model in his field that has beat big oil in court, solved cases with it. Light years smarter than me about all of that. A lot of hard evidence to suggest were being lied to about timelines of fossil fuels.

I understand I sound alarmist, however, when I hear “FIA Introduces E-Kart Class” my brain immediately sees a red flashing warning light of a mandate coming that people will have to contest. The FIA is definitely playing on a global scale. I get worried about choice being taken away, that’s all.

Haven’t read much about synthetic fuels. Will have to do some research.

@NikG Few things :

1 - Electric motor efficiency

Only partially true, as it is peak efficiency. Electric motors show 90+% efficiency only when within the ideal RPM/Mass ratio range, load, heat and when mitigating copper losses. Using a electric motor in a racing condition will lower its efficiency quite a bit, more like 70-80%. Still a lot better that ICE, but not 90%. So yes, you can run a big motor, to have plenty of torque and run a very low gearing, but then you are increasing the weight and reducing the appeal of a kart handling. You could go with an Axial flux motor, which has a much better torque/mass ratio, but it would require design an high voltage battery (96V at least). That is doable but requires good electrical engineering skills.

2 - Battery management

Looking from a outdoor rental track POV. The closest tracks to me are Mariembourg and Spa. Both tracks can get 25 karts running during their standard arrive-and-drive sessions of 15 min, and up to 50 karts during their SWS/league races. What does that mean ?

You need 3 batteries per kart at least to ensure uninterrupted running time. So you are charging 100 batteries at the same time, which would require a complete overhaul of the infrastructure.

But lets assume you have the means to charge those batteries. You still need to change them after each sessions. Worst case scenario, you need to change 25 batteries every 20 minutes, over 5 hours of business. BlueShockRacing claims 12.5kg per battery of 35Ah.

3 - Staff management

(5h * 60) / 20 = 15 sessions

15 session * 25 karts = 375 battery changes

375 * 12.5 = 4687.5kg to move during the day

Now lets imagine a 8h endurance, 45 karts, 20 minutes stints per kart :

(8h * 60) / 20 = 24 stints

24 stints * 45 karts = 1080 battery changes

1080 * 12.5 = 13500kg to move during the day

Do you think your staff is going to accept that ?

4 - Upfront cost

Off the shelf cost for a 390cc Honda engine is 800 euros VAT incl. A good clone would cost around 150 euros VAT incl.
PU + battery from BSR (X2, 8hp) would cost you 5000 euros VAT excluded. I don’t think I need to make the calculation, it is pretty clear.

5 - Energy economical and ecological cost

Even if the grid can supply the energy during the business hours, it still costs a lot, especially in Europe with the natural gas crisis and the ever rising electrical costs (and I am living in France, where most of our energy comes from nuclear fission). I know that some tracks have conducted researchs to switch to electric, but the infrastructure requirements (solar panels, diesel generator) just made it financially not viable. Then, it is only as clean as the source of the energy. Many developed countries still relies most on fossil fuel to get their electricity. And finally, do you really want to support the cobalt mines in Africa, the ones that use kids labour, for a leisure usage of those batteries ? Or support the lithium exploitation that uses a shit ton of water in countries that are already strained ? (Granted CATL is pushing sodium-ion batteries, but they are a lot less energy dense)

EV has its place in the mobility landscape, but it is not adapted to conventional racing, and even less to outdoor rental karting facilities. Indoor somewhat works, on the tracks that have the real estate to have enough chargers, and dont run more that 12 karts at once on the track.

I would say to some extent karting benefitted cultural and commercially from this, quite significantly so. You do need a bit of hassle to get people addicted, even if they don’t ‘want it’. It also allows for a media to be viable because it creates a copious amount of things to write about. When you have a healthy media you have people financially invested in the growth of the sport. At the moment I don’t really see this within the sport too much. I see businesses trying to make more money out of the current number of competitors… or even less. It also allowed for products to come to market. new ideas… this all needs ad spending. It become a self-sustaining ecosystem.

The margins in media are so thin you need numbers, so you really have to have numbers. But also a strong readership. But all media is on its arse now. The reason we now have effectively a ‘Formula 5’ of karting is because that’s the only marketing angle left with any bite, and it doesn’t cost anything either. This is all the alchemy that took karting to pretty decent heights back in the day in the ‘60s. It can’t really be replicated because you needed the combination of multiple factors that are borderline ethereal in nature. The point I am making is that ‘bugs’ are often actually features (this gets recognised too late far too often). I think this is partially why motocross has remained culturally a fair bit stronger than karting. You can’t really ‘easify’ it, though it has its own issues.

Having said that, and for what it’s worth (not much) I am not really bothered where karting goes now, electric or whatever, because I am not enamored with what’s on offer in today’s market. It doesn’t affect me either way.
