Detroit Can Build a Small Truck. It Can't Build a Kei.

TL;DR: Trump told the auto industry to build "kei style" trucks in America. Two startups are already trying. Slate Truck launches at $27,500 and 152 inches long. Telo MT1 launches at $41,520 and 152 inches long. Both are bigger than a Mini Cooper, and both are roughly twice the size and three to five times the power of an actual Japanese kei. That gap is not a marketing problem. It is the entire reason kei trucks exist.

A real kei truck is not defined by being small. It is defined by squeezing into a Japanese tax bracket that does not exist anywhere else on earth. Yellow license plates. Road tax under $50 a year. A regulatory ceiling of 660cc and 63 horsepower. A parking exemption that lets rural drivers register without proving they own a parking space. Take all of that away and you do not have a kei truck. You have a small truck.

That is what Detroit and a handful of US startups are actually about to build. And it is not what kei truck enthusiasts are picturing.

What Trump Actually Promised in December

On December 3, 2025, President Trump told a press conference that he had "authorized" Secretary of Transportation Sean Duffy to "immediately approve the production of" kei trucks and cars in the United States. According to The Fast Lane Truck, even Duffy looked surprised. We covered the regulatory pathway in detail when the announcement happened. Short version: presidents do not unilaterally rewrite Federal Motor Vehicle Safety Standards.

The press conference did contain one specific instruction that has not been talked about enough. The administration noted that kei vehicles must be manufactured in the United States to be sold here. This was not Trump saying he would let Suzuki ship new Suzuki Carry trucks into the country. It was him saying he wanted American factories building "kei style" cars. That is a fundamentally different ask, and it changes the math on what you would actually get.

A December 19, 2025 legal analysis from Covington and Burling spelled out what stands between current law and an American kei truck: NHTSA rulemaking, FMVSS exemptions, and a category that does not yet exist in US regulation. Even if all of that happens, the result is not a Japanese kei truck. It is a new category of small American vehicle that borrows the silhouette.

The Real Definition of a Kei Truck (the Part Americans Skip)

Most US coverage of kei trucks describes them as "small Japanese mini trucks." That is technically accurate and completely misses the point. Kei is short for keijidousha, which translates to "light vehicle." It is a category written into Japanese law in 1949 and last updated in 1998. To wear a yellow plate in Japan, a vehicle must measure no more than 134 inches long, 58 inches wide, and 79 inches tall. The engine cannot exceed 660cc or 63 horsepower. Cargo capacity tops out at 770 pounds. Wikipedia's kei truck entry walks through the regulatory history if you want the full timeline.

In exchange for living inside that box, kei owners get a tax structure no other car class on the planet enjoys. Annual road tax runs roughly 4,000 yen (under $30) compared to 30,000 yen or more for a regular car. Insurance is cheaper. Tolls are discounted. Most importantly, in rural areas you do not have to provide a parking certificate proving you own a dedicated spot, which is required for any larger car. For a Hokkaido farmer, that single rule is the reason he drives a Daihatsu Hijet instead of a Toyota Hilux. Read what is a kei truck for the deeper background.

The 660cc engine is not a quirk. It is the defining engineering constraint that has shaped Japanese automaker R&D for 75 years. Three cylinder turbos that rev to 7,000 RPM. Five speed manuals geared for stop and go city traffic. Solid rear axles tuned for 770 pound payloads, not 2,000 pound payloads. Cab over engine layouts that put the driver on top of the front axle to maximize bed length. None of that engineering DNA exists in Detroit, and no US automaker is going to develop it from scratch for a niche category.

Slate Truck: $27,500, Made in Indiana, Not a Kei

The closest thing to a US built kei competitor that actually has a delivery date is Slate Truck. The Bezos backed startup plans to start production at its Indiana plant by the end of 2026, with a starting price of $27,500 before federal incentives. According to InsideEVs, the base truck is a two door, two wheel drive electric pickup with crank windows, no infotainment screen, no speakers, and unpainted composite body panels.

Sounds austere enough to be kei adjacent. It is not. The Slate Truck measures 174.6 inches long with a 108.9 inch wheelbase, which makes it 40 inches longer than a Suzuki Carry and roughly the same length as a Ford Maverick. The single rear motor produces 201 horsepower. The smaller battery option weighs the truck north of 3,200 pounds. Range is 150 miles on the base battery, 240 miles on the upgraded pack. Carscoops reported in April 2026 that production was running behind schedule and the launch had gone quiet.

For perspective: a current generation Mitsubishi Minicab is 134 inches long and weighs about 1,800 pounds. The Slate is more than three feet longer, almost twice as heavy, and over three times the horsepower. It is a small American electric truck. It is not a kei.

Telo MT1: $41,520, 500 Horsepower, Definitely Not a Kei

Telo Trucks gets cited even more often as the "American kei" because it is intentionally pitched as a tiny pickup. The MT1 measures 152 inches long, which Telo's marketing compares to a Mini Cooper. Pricing starts at $41,520 for the single motor rear drive version and climbs to $49,999 for the dual motor long range. InsideEVs reported after the prototype reveal that production was targeting late 2025 or 2026.

The single motor MT1 makes 300 horsepower. The dual motor version makes 500 horsepower and hits 60 mph in 3.5 seconds. Payload is 1,700 pounds. Towing is 6,600 pounds. The bed runs 60 inches with a folding midgate that swallows eight foot lumber. TFL Truck got an early ride in the prototype and described it as a serious work truck in a small wrapper.

That is impressive engineering. It is also nearly five times the horsepower, twice the payload, and roughly five times the price of a 2026 Nissan Clipper Truck, which Carscoops reports starts at ¥1,344,200 (about $8,500 at current exchange rates) in Japan. Telo is building a great small electric truck. It is not a kei. It is a Mini Cooper sized work pickup that costs Maverick money.

Why Detroit Cannot Build a $9,000 Mini Truck

Even if NHTSA wrote a clean kei vehicle category tomorrow, the Big Three are not going to build one. The economics do not work. US automakers killed every subcompact car they made: Cobalt, Focus, Fiesta, Spark, Versa, Sonic, Yaris, Mirage. Margins on small cars are razor thin and dealer markups stack the deck against them. A $9,000 mini truck does not fund a $14 billion CEO compensation package or a $90 million Super Bowl ad buy.

Honda and Toyota could theoretically build a kei style truck in their US plants. They have the engineering DNA, the supply chain experience, and the manufacturing footprint. They will not. Their US factories are tooled for Civics, RAV4s, and Highlanders, all of which sell at margins that make tooling for a 660cc truck look like setting money on fire. Honda makes more profit on one Pilot Elite than it would on twenty Acty Trucks. Bring a Trailer auction comps for imported keis routinely sell in the $12,000 to $20,000 range, which sounds high until you remember that those are 25 year old trucks that have already paid down all their tooling costs in Japan.

The American buyer who actually wants a kei truck mostly wants three things: a sub $15,000 cap ex, a manual transmission with four wheel drive, and a turning radius small enough to whip around a barn. Detroit cannot deliver that for under $25,000 and probably not under $30,000. Even a comparison against a US pickup tells you why: Maverick starts at $26,000, gets 200 horsepower, and is 199 inches long. It is the floor of what American factories will profitably produce.

What an "American Kei" Would Actually Look Like

Suppose Trump's executive enthusiasm survives the regulatory gauntlet and a real domestic kei category gets written. The vehicle that emerges will share three or four traits with a Japanese kei and otherwise be a different animal.

It will be electric. There is no path to building a profitable 660cc internal combustion drivetrain in the US, full stop. Telo and Slate already saw this. A US built sub kei would run a small electric motor of probably 75 to 150 horsepower. Range would be 100 to 150 miles. That is fine for a farm runabout but not for the cross country uses American buyers fantasize about.

It will be 145 to 160 inches long, not 134. American crash standards demand crumple zones, side impact bracing, and rollover bracing that you cannot fit inside a 134 inch envelope at sub $20,000 cost. Even if NHTSA writes a low speed sub kei category similar to existing low speed vehicle rules, the resulting truck will be longer and heavier than a yellow plate Carry.

It will cost $22,000 to $35,000. That is not a Japan kei price. It is the floor of what American assembly economics will allow. Hagerty has been tracking imported kei prices and the math holds: even with shipping, compliance, and dealer markup, importing a 25 year old Hijet for $12,000 will continue to undercut anything Detroit can stamp.

It will not have a tax bracket. The single biggest reason Japanese buyers choose keis is the structural tax discount. The US has no equivalent. There will be no $30 a year road tax for an American kei. There will be no parking certificate exemption. The thing that makes kei ownership rational in Japan does not transplant.

What you will get is a small American electric work truck, badged as a kei adjacent product, sold in volumes that disappoint everyone, and priced above what an imported Honda Acty would cost you today.

So What Should You Actually Do?

If you have been waiting on the Trump announcement to walk into a Toyota dealer and buy a new kei, stop waiting. That dealership is not coming. Even in the most optimistic scenario, a US built kei style truck arrives in 2028 or 2029, costs more than an imported one, and lacks the engineering heritage that makes a real kei feel like a real kei.

The path that actually works right now is the same one that has worked since the early 2010s. Find a Japanese auction listing on Goo-net Exchange. Use a reputable importer to handle shipping, compliance, and titling. Make sure your state allows registration before you commit. Read our pre purchase checklist and our cost breakdown so you know exactly where the money goes. Total damage for a clean 2000 model year Subaru Sambar lands somewhere between $11,000 and $16,000 delivered, which beats every projected American built alternative.

The Trump push has at least one good side effect. It has accelerated state level legalization, with bills in Maine, Vermont, and a handful of other states using the federal momentum to argue for clean state registration paths. That helps existing imported kei owners more than it helps anyone waiting on a Slate or Telo. The community over at r/keitruck has been tracking state movement in real time.

The Bottom Line

A US built kei truck is not a kei truck. It is a small American truck wearing kei aesthetics. The size, the price, the engine, and the tax bracket that define a kei do not exist outside Japan. Slate and Telo are decent small electric pickups in their own right, but they cost three to five times what a real kei costs new in Japan and roughly double what an imported 25 year old kei costs delivered to your driveway. MotorTrend has been covering the American mini truck phenomenon for years, and the conclusion is consistent: the appeal is the import oddity, not the spec sheet.

Trump opened a regulatory conversation that needed to happen. The end of that conversation is probably a new American small truck class, not a flood of cheap Japanese style mini trucks. If you want a real kei, the path is still the same: import one yourself or buy one from a US dealer who already did. The yellow plate is not coming to Detroit.
