Modified Side By Side UTVs Might Be The Easiest Solution To American-Built Kei Cars

It’s an odd time here at the Autopian. Our Mercedes Streeter and other writers have spent much energy since the launch of the site trying to find ways to import and legally drive ultra-mini Japanese “kei” cars, and it’s often felt like a losing battle. The question that’s come up recently, however, is what will happen if these kinds of tiny automobiles are not only welcomed in America but actually produced here as an affordable alternative to “normal” cars.

Is this even possible? Currently, the only non-golf-cart four wheeled vehicles built in American capable of near-kei speeds starting in the $10,000 to $15,000 are side-by-side ATVs. It’s not like you’re going to drive those on the street, right? Well, what if we made some tweaks or revisit an alternative I did a while back where you actually could?

Cuter Than A Kei Pop Band

The Kei-in-America thing is a complex subject that many have obviously been debating recently. It’s especially difficult to consider all the ramifications when we are now possibly considering domestic-made “kei” type cars that aren’t 25-year-old playthings. Would brand new little kei cars in America need to adhere to the same safety and emissions regulations as “normal” cars?

Here’s the bigger query: do Americans other than crazy people like us Autopians even want to buy such cars? Based on recent sales data, the answer is a resounding “no”. New cars like the Honda Fit and Chevy Spark are mere memories in America, and most of the surviving Smarts exist either as engineless props in rehab centers or in the possession of an author at an ill-publicized website. It’s not like these very small, inexpensive cars are bad; I’ve rented a few on business trips and they’re far better than some larger compacts from a few decades back (and a hundred times better than your mom’s old Malaise rides). So what’s the issue?

More than likely it’s a few things. First, driving such a car can be like wearing Sears Toughskin jeans as a kid back in the early eighties; they fit, they worked, but in a world of Jordache and Sassoon it was painfully obvious that you were a second-class citizen. It’s a badge of shame, since people are generally very shallow. If you’ve risen above being concerned about what people think, I congratulate you, but most car buyers have not.

Also, you can put as many airbags and headrests that will fit in one of these Kei-sized things, but you simply aren’t going to win in a collision battle with the average American SUV, much less a F-800 Mega Ranch Dually or whatever.

Car companies are more than happy that you feel this way. They don’t make any profit on these super small cars, and an even cheaper car would have less incentive for them to sell. Worse than that, chopping a foot or two of length and a few amenities out of a Chevy Trax won’t give you a $15,000 vehicle anyway. I can virtually guarantee that American car companies are not going to eagerly make kei-type offerings; actually, they probably just won’t.

Realistically, would a sellable American “kei” even be “car” in the normal sense? I say that maybe it can’t, but it doesn’t have to be.

Baby Hummers Are Coming?

Side-by-sides are a bit of an odd duck in the world of motor vehicles; they’re specialized use vehicles that can tackle off road challenges many larger vehicles cannot.

Many are perfectly capable of keeping up with local urban traffic, but in many states they can’t be legally driven on public streets. Admittedly they don’t have the safety equipment of a “normal car”, but neither do motorcycles or things like Slingshots or Can Ams that can lawfully share roads with cars.

Our Jason Torchinsky used to daily drive a glorified golf cart called the Changli all over a small college town, but he ran into issues when given a Polaris Ranger side-by-side to test last year. Despite being far faster and more capable on the road than a number of his own cars, he basically couldn’t do anything with it, or at least not legally and with the blessing of Polaris on city streets. You might already know this, but Jason does not live on a 500-acre homestead, nor does he possess a twin-axle trailer and the aforementioned F-800 Dually to tow a Polaris Ranger with. This specialized nature of the side-by-side means that the market is limited and could explain why this industry had been suffering a little while back. That’s understandable, since any “recreation” vehicle is likely to be a sales dud when the economy makes even a slight “correction”.

The version of the Ranger that Jason sampled was a higher-level model that cost well over $40,000, but it had far more capability than most people would ever need. A much lesser specification and priced Ranger would seemingly be fine to just drive on city streets and, at worst, get through deep snow or flooded gullies; things that a Japanese-style kei car likely couldn’t do.

It’s even more than actual capabilities, though. The appearance of a “tough” vehicle has emotional value to many buyers. I lose count of the number of $50,000 plus big-loud-tired Jeep Wrangers that I see on my suburban drive to work. There are few worse vehicles I can think of to use as a daily commuter, but buyers must see a value attached to a look that equates with big, tough, and heavy SUVs.

A side by side likely won’t be any safer than a kei car, but somehow sitting higher and having a “roll cage” gives the impression of these qualities. I’m not saying that’s good; it just means that people are psychologically more inclined to purchase a vehicle that seems to be more of a match for roads full of SUVs (as incorrect as that assumption might be).

None of this matters as much as the biggest elephant in the room; something bigger than safety and speed.

“Oh, Should I Write Them A Note?”

Cars are more than just consumer products: they’re part of the culture. That, more than anything, might be where Kei cars won’t work in America, but side-by-side type vehicles could.

You wouldn’t think that a tiny British subcompact would be embraced by members of the world’s biggest band, but despite their wealth, members of the Beatles owned and were regularly spotted in Minis. These cars simply transcended the typical “class” designations that would prevent an A-lister in America from rocking a Mitsubishi Mirage today (though the Toyota Prius was once a darling of eco-conscious celebs).

Sport utilities are sort of the same thing today. The biggest stars in the world can regularly be seen rocking Jeeps. Also, it never would have occurred to people of 1965 that teenage girls thirty years later would beg their parents to grace them with a modern version of a World War II military vehicle. It’s a pointless car for a bedroom-community kid, but how many duck-covered Wranglers do I see in the high school lot? It’s all about image.

Of course, high schoolers would never tool around in an actual 1941 Willys; today’s Jeeps are not exactly Lexus, but they’re far more domesticated than surplus army vehicles. A side-by-side is also a rather rudimentary machine, but could we make one that wasn’t quite as hardcore?

Special Kei

Making it legal to drive current side-by-sides on the street wouldn’t necessarily be the answer to American-built keis. The ones that are the most car-like are way too expensive, the inexpensive ones aren’t car-like enough, and all of them are engineered for far more heavy-duty off-road use than street operation. I can see two ways to approach the street side-by-side solution.

Entry Level: MUV (Micro Utility Vehicle) Polaris Sunova

An entry-level I-just-need-transportation street SBS might be what I’ll call the Micro Utility Vehicle; a modified existing product to be more usable on the road and decontented of all the heavy-duty off-road business.

The least expensive four-seat Ranger I “built” for $13,799 here can supposedly tow 1500 pounds (a two-seat version lists for around $2000 less). It also has an AWD system that features on all Rangers, which you really wouldn’t need if you’re doing mainly street driving (but I like the extra ground clearance) any more than you need towing capacity.

Screenshot 2025 12 19 164838
Polaris

Here’s the modified version that I’d call the “Sunova” since that’s something our David Tracy says a lot around here. I believe that a version of the 570 with rear drive only (ditch all of the AWD equipment) and made in higher volume would be less expensive, and the money saved could be put into features that would make it more usable on the street.

Polaris Sunova

These modifications would include car-type wheels and tires instead of the super-wide-tiny-diameter SBS wheels. The big push bar in front can give way to more of a bumper/fascia panel to cover the exposed fronts of the wheels. Naturally,  side doors would have to be included but I’d make stretched fabric ones standard instead of far more costly rigid versions. Headrests attach to the “roll bar” and I’m showing a cargo cover in back, as well as roll bar extensions that might be optional. I would think that a large number of buyers would go to aftermarket sources to get the many, many accessories for the Sunova at a far lower cost than what the dealer could provide. Honestly, the aftermarket business for this vehicle could create its own pretty lucrative industry.

The Sunova shown above has the vacuum-formed rigid doors, but here’s the Sunova with the standard soft doors:

Polaris Sunova Fabric 12 19

Here’s an animation showing the stock Ranger and the Sunova with the standard fabric doors and the optional vacuum-formed doors:

The doors obviously could be easily removable, and in warmer locales might never be used. I don’t think I’d want to run this thing in Minnesota winters, but with an optional heater and maybe even rigid doors, it could be a pretty good snow vehicle like an old VW Beetle was on those tall, skinny tires, even with just the driven rear wheels (and the engine weight over them). I do think that rigid doors could be made for far, far less than the nearly $1000 per unit some makers charge for these things now; once again volume is the driver here.

What if you’re willing to spend more money on something fancier, maybe faster and more trick than what you might typically get for $20,000 or $25,000 today? Also, what if this were a little EV for the ultimate in efficient around-town use? You might want a Sherpa.

Upper Level: MSUEV (Micro Sport Utility Electric Vehicle) Polaris Sherpa (also available as gas powered)

Some time back, I envisioned a more street-friendly street Ranger that would have been electric powered, but I’m thinking now that it might be offered in a gasoline-engined version as well. Still, as an EV, you’d be eligible for credits, and who knows if even more such incentives might be provided by governments to encourage smaller, greener US-built products. This is the Polaris Sherpa I presented a while back:

Polaris Sherpa
GEM Vehicles (backdrop)

Here’s how I described this thing a while back:

ADVERTISEMENT

Styling of what we’ll call the Polaris Sherpa series will follow the same pattern as automobile crossovers: a combination of rugged off-road machines with the cleaner forms of street cars. The body will sit high without being as far off the ground as a Ranger; grey plastic rocker trims and sharp breakover angles front and rear create the look of something off-road capable. A grey hood and “roll bar” contrast the color-painted sheet metal.

Main View Notes 2 10

Four side doors could feature windows with crank roll down sections, and the Sherpa can offer another trick not seen before: you could remove roof panels over each seat, the rear window glass and all of the side glass to give a convertible feel.

The cargo area is shorter than the Ranger; optionally you could fold or remove the rear seats and even remove the rear window to carry larger objects in a way neither any current UTV or LSEVs can do.

Rear View 2 10

An optional, integrated trunk lid could offer weather protection and security for your cargo.

In the Sherpa, the dashboard is simple, with the optional entertainment system or screen being just a standard double DIN opening that you can use as a storage bin or install any damn thing you’d like (and be able to upgrade five years from now per Jason’s new rules). Air conditioning and power windows? Who knows; even if the price starts to get up there you still don’t have a lot of open-topped off-roadable EVs out there for the price of a loaded subcompact.

Dashboard 2 10

I’d like to esentially move all the controls to the steering wheel area.

Main Controls 2 10

Like the Sunova, you could possibly get car-type tires, wheels, and bumpers as an alternative to the more off-road style pieces, and maybe even an add-on rear cargo cap to make a sort of Jimny-style micro SUV.

Polaris Sherpa Wagon

For power, I could see that EV having a front motor or the option of front and rear motors to allow all-wheel-drive. We’d engineer it to allow for a gas-powered model as well, with an engine in front to replace the “frunk” and a gas tank to replace the batteries. How much power? I’m still seeing less than 60 horsepower with both motors, the rear one getting the bulk of the power. If you want to duke it out with big SUVs on the highway at 85 miles an hour, this isn’t your ride. I am sure there will be aftermarket places selling modifications to make these go at frightening speeds. I wouldn’t do that, but I get passed by bikers with their front wheel in the air doing 80, so I promise skunkworks hyper-powered MSUEVs would be a thing as well.

ADVERTISEMENT

Honestly, I think a firm like Polaris might need some help with this thing from an OEM car maker. At the same time, those large domestic big three wouldn’t want to make these kinds of things anyway, but wouldn’t mind one on their lot to sell, especially if subsidies and tax credits might be in the works. A partnership perhaps, where both Polaris and a “real” passenger car company might sell the same thing they’d collaborated on with different grilles and branding?

We Can’t Find A Way To Make It Safe, But Maybe At Least Cheap?

Don’t kid yourself about kei car abilities; they’re great for certain uses, but they’re limited. Reviews of the vaunted Honda N-One emphasize that even this benchmark isn’t meant for highway travel, so you’re stuck driving around town only in a cramped box that you can’t open up to enjoy the sun in summer or with the ground clearance and ability to grind through the snow in winter.

You can’t argue with the facts; it’s probably quite unlikely that Kei cars are coming to America, and even more unlikely that they’ll be built here. Car manufacturers have no interest in building something that recent history has proven few people want, and they absolutely have no interest if it’s a product that they can’t make profitably.

However, you know who could? Do you know who is basically making them already? Side-by-side manufacturers. Plus, if they could double or triple their current production numbers on something engineered to be more suited for lighter-duty use, they could likely sell them for less money than their current products. Better than that, their American-based manufacturing plants could thrive; that’s something we’d all be happy to see.

Running a modified side-by-side on the street still seems sort of crazy, but is it any worse than running some tiny Japanese microcar? I say that this insane idea just might be ohKei.

Side-by-sides are horrendously priced, as they are now. Not to mention that safety is much more “image” than “reality”.

SxS are just a worse car in every sense, even with a box on top for keeping out the elements.

That last concept of the electric AWD convertible SxSish thing would be getting a hard look from my significant other. They are getting the next vehicle and are insisting it’s a convertible. This would tick so many boxes. I could tow a light trailer locally, have room to store stuff out of sight and probably be able to remotely precondition it with an aftermarket accessory. We have a second “real” car to do car stuff so a smaller vehicle for their commute would go over fine. As long as it can do 70 mph on flat ground.

Yeah, it’s the next rational step. There was public outcry about horrific crashes, we engineered safer cars, people ran from them and bought SUVs. There was public outcry, we engineered safer SUVs, people ran from them and bought SXS for the neighborhood. The public, when asked about safety, demands it. But they don’t buy it.

If I had the money, I’d mass produce an inexpensive, 3-wheeled, one-seater, tadpole layout, with the aerodynamics of a velomobile, maybe 160mm ground clearance, 750mm height to roof, 3,000mm length, and maybe 1,000mm width. It would be a fiberglass monocoque with an integrated steel roll cage added to reinforce the safety cell, have AWD using e-bike hub motors in each wheel and a power-dense battery(perhaps a 36S6P pack of MOLICEL P60C).Wheels would be 16″ DOT with 16×2.5″ tires. Hydraulic brakes front and rear with an additional cable-pull e-brake for the rear wheel that also serves as a parking brake.

Basically, a street legal single-person Shell Eco Marathon race car or Electrathon car, designed for maximum efficiency, with as much horsepower as allowed by the Kei car classification.

All of the EV drive system parts including motors/controllers/charger/battery/low-voltage electronics needed to make this possible are available off-the-shelf for under $5,000 at retail prices, with significant per-unit cost reductions ie everything can be purchased/manufactured in bulk. Then there’s the rest of the vehicle, production cost being highly variable depending upon how it is produced(hand made being primarily labor cost with no limit, but mass produced in a factory allowing manufacturing cost to approach raw materials which would be about $3k).

I’d end up with a vehicle weighing under 200 lbs, making 63 horsepower peak and 500+ lb-ft of torque between all three wheels, is safer than a motorcycle, is enclosed for all-weather operation, can be driven in the snow as long as the snow depth isn’t more than the ground clearance, and the vehicle will even able to have integrated into it features such as climate control, a radio, trunk space, maybe even airbags. The battery pack of 4.6 kWh should be enough for at least 150 miles of range at 70 mph if it needs 2 kW from the battery to hold that speed, which is doable if you get the drag nice and low and don’t compromise the aerodynamics for looks. Designed right, it would cruise 100 mph with about 5 kW draw from the battery.

And all of the electric components in it would be using open-source software, and be very DIY-repair friendly, since it would use hobbyist-grade e-bike parts.

You know what this product would give the buyer? VALUE FOR THE MONEY. You see, a poverty spec vehicle of this sort could easily be made to accelerate with $250,000+ supercars/hypercars in a straight line, and perhaps keep up with them in the corners on a race track. It probably won’t have stability beyond 130-ish mph, but that’s still plenty enough for a vehicle intended for street use. And on the street, bar none, it would be the cheapest possible thing you could operate outside of a bicycle. A full charge would cost $0.50-$1.00 in the USA depending upon where you are at, replacement parts would be readily available for anything electronic and basically plug-and-play, and it would be a no-nonsense, low-maintenance vehicle so small you could possibly carry it into an apartment.

THAT is the Kei car I want to build in the USA. A 3-wheeled, full-suspension electric racing kart on crack that is barely street legal, and if mass-produced, CHEAP. All the gen-Z kids priced out of used car ownership today would flock to something like this like flies on shit, and they’d not only have transportation that’s cheaper per mile than taking the bus, but they’d also be able to piss off all the people who blew six-figures on overweight/overcomplicated “sports cars” by being able to blow their doors off at the stop lights. And it would be about as eco-friendly as a car could get. Something like this mass produced could come in at under $10k.

Where I live, side-by-sides have been legal on the roadways for the past 5 or 6 years now. They don’t even have to be road-legal. There are signs as you come into town that state: All City Streets are ATV Routes Unless Posted. It used to be the major 2-lane state highway that went through our town was the exception, but they changed it a couple of years ago so now ATVs are allowed on every road in town.

It would be nice if Kei cars could be allowed the same consideration on local roads as well.

Ugh, I feel like this concept may be inevitable, but still I hate it. Kei cars are civilized, styled to be somewhere between pleasantly unassuming or all the way towards cute, and they’re meant to be driven on the street responsibly.

Side-by-sides are none of that. They’re styled to look more aggressive than a Hummer like they’re compensating for something, and built to indulge their buyers’ urges to rip the hell out of the landscape on a whim. Basically, they appeal to obnoxiousness.

I live where side-by-sides are at least quasi-legal on secondary roads. There’s one somebody rips around the neighborhood in like an extra-noisy go-kart on steroids.

If they’re going to be turned into cars, they need decent mufflers on them to quiet the noisy, clattery little engines in them. I’d rather the styling (and marketing) was a bit more restrained because we really don’t need to encourage more bad behavior on the roads than we already have with many big SUV drivers.

While discussing our needs and wants for the home my wife and I would like for our retirement, we were discussing dealing with a long driveway since we both agree we’d prefer to have a few acres of land and some setback from the road, since we both prefer quiet, privacy, and having more nature and less manicured lawn around us. I said we’d want to find an old golf cart to deal with grabbing the mail from the box out by the road and hauling the garbage bins out on a small trailer. They have roofs, windshields and side curtains for rainy and cold weather, so it would be fine for quick runs. She said she’d prefer a side-by-side because it could be fully-enclosed, with heat. I countered that they’re stupidly expensive, horribly noisy (she herself complains about the ones that the kids drive in the neigborhood…) and as a utility vehicle for tending to a small, wooded property, less maneuverable than a quad ATV. She’s still in favor of one. I feel like she’s going to have one anyway, someday. I’d rather pick up both a quad for dealing with land management and an old golf cart for driveway duty, probably for less money. I just can’t justify the price of side-by-sides except perhaps as luxury hunting vehicles where there are trails wide enough for them to go. But a fully kitted-out quad still seems more useful to me.

Absent it turning into a foam ball like in Demolition Man after a collision, you’re going to lose to your average Canyonero because physics.

I’ll buy a JDM Acty or Sambar and use it instead of a side by side for a farm vehicle every day of the week, though. Just waiting for the airbag equipped models to be more readily available.

SO many of the side by sides on the trails and off road parks are bigger than my buddies cj-2 but his jeep is not allowed on the atv trails like the SXS’s are. Many of them cost as much as a new jeep.

$20k doesn’t sound too bad when you compare it to $40k or more for a UTV that has similar driving capabilities on pavement. I wonder how much a federalized Jimny would cost? Probably too much, I know.

True, 20k is base though,just looked it up- to get a roof, heater, etc. it easily gets into the 30k range. The Mahindra is a ” real car” just with a speed limiter though so I would put it above a UTV for on road ability.
The Jimny would be great as well. The Australian model starts at $34,990 AUS so about 23,300$ USD. I can’t imagine that the US standards are much tougher than Australia if emissions stuff/ CAFE and import tax are reduced.
