By packing batteries and an electric drive axle into a tandem trailer that fits between a conventional semi truck and trailer, Revoy EV promises to “electrify” trucking and cut a fleet’s fuel bill in half. It sounds amazing – but eleven tons of questions remain.
The Revoy EV concept is deceptively simple. A tractor’s 5th wheel pairs up with the Revoy’s hitch. Then the trailer that the semi is set to haul attaches to the Revoy’s 5th wheel. Some AI embedded in the Revoy’s electronic control units does some number-crunching and the three-part truck, trailer, trailer combo then hauls off down the road, with the Revoy’s high-torque e-axle providing most of the power to accelerate the load and diesel power where it’s most efficient: on the highway.
The best part, according to Revoy? Truckers can add the Revoy EV trailer to their rigs with no up-front costs.
“We offer a really different and much better and easier path for fleets to go electric,” offers Revoy EV’s founder, Ian Rust. “We offer a service, (zero money up front for the unit, then) customers pay us by the mile. It’s really more of a fuel product. We charge them for the diesel we save them, altogether with the residual diesel, and our fees that are all inclusive.”
The Revoy EV has a range of about 250 miles, which comparable to the 2nd generation Volvo VNR Electric and the Freightliner eCascadia models. “On a 250-mile run, a truck getting 7 mpg might burn 35 gallons of diesel, which we’ll say costs $4/gallon or $140,” writes Alex Lockie, from the Commercial Carrier Journal. “The Revoy EV would cut that in half, approximately, and bill the fleet for a cut of the difference.”

Revoy is launching with two “swap stations” already up and running in Texas and Arkansas, where drivers can pull into the station, be greeted by a Revoy attendant, then swap out their spent battery “in about five minutes or so,” according to the press release. Rust adds that Revoy has stations planned for California and Oregon as well.
Electrek’s Take
Where do we start? On the one hand, the Revoy EV is very much not vaporware. This is a thoroughly conceived, well-engineered, and seemingly well-funded effort to bring someone’s big idea to life. On the other hand, the concept itself seems deeply flawed.
The first major problem with the Revoy EV is its weight. The electrified trailer weighs in at about 22,000 pounds, according to the company – around 2,000 pounds lighter than the previously mentioned Volvo VNR Electric and as much as 6,000 pounds more than a Freightliner eCascadia. National rules say that without a special permit, a semi-truck and the trailer it is hauling can’t collectively weigh more than 80,000 pounds in total. Worse, the Revoy doesn’t fit into any special legal loopholes that can help make that mass go away (because the Revoy isn’t a ZEV, it doesn’t even get the extra 2,000 lb. GVWR allowance a BEV gets). That means adding a Revoy trailer to your rig effectively negates your ability to haul 22,000 lbs. of the stuff that, you know, you’re actually being paid to haul.
Add in the potential safety risks and generically “weird” handling characteristics presented by adding an extra few articulations into the mix and the Revoy starts to look even more like a liability.
Still, the Revoy guys aren’t dumb – and a number of knowledgeable industry people have jumped in to defend Rust’s concept. “In high-value freight at least,” offers Lockie, “the trend has been toward the extreme majority of loads cubing out before they ever weigh out.”
Rust, to his credit, at least acknowledges the problems. “The key is when we encounter those trailers that can’t afford the weight (of the Revoy EV), we wave them on,” he says. “We looked at the data … two thirds of loads can accommodate the extra weight.”
With so many commercial fleets complaining that the 2000 lb. EV adjustment isn’t enough, I (for one) question Rust’s confidence. Still, I’m just one guy – and you, dear readers? You’re smart. Head on down to the comments and let me know what you think of the Revoy EV, and whether or not you think it’ll be a staple of trucking’s future.

That network of dependable high-speed chargers, paired with solid app integration that makes it easy for Tesla drivers to find available chargers just about anywhere in the US, gave the brand a leg up – but no more. By opening up the Supercharger network to brands like Ford, Hyundai, Kia, and others, Tesla has given away its biggest competitive advantage.
Add in charging and route-planning apps like Chargeway, that make navigating the transition from CCS to NACS easier than ever with its intuitive colors and numbers and easy on/off switch for vehicles equipped with NACS adapters, and it feels like the time is right to start suggesting alternatives to the old EV industry stalwarts. As such, that’s exactly what I’m going to do.
Here, then, are my picks for the best Tesla S3XY (and Cybertruck) alternatives you can buy.
Less Model S, more Lucid Air

Developed by OG Tesla Model S engineers with tunes from Annie Get Your Gun playing continuously in their heads, the Lucid Air promises to be the car Tesla should and could have built, if only Elon had listened to the engineers.
With panel fit, material finish, and overall build quality that’s at least as good as anything else in the automotive space, the Lucid Air is a compelling alternative to the Model S at every price level – and I, for one, would take a “too f@#king fast” Lucid Air Sapphire over an “as seen on TV” Model S Plaid any day of the week. And, with Supercharger access reportedly coming later this quarter, Air buyers will have every advantage the Supercharger Network can provide.
HONORABLE MENTIONS
Less Model 3, more Hyundai IONIQ 6
2025 Hyundai IONIQ 6 Limited; via Hyundai.
Hyundai has been absolutely killing it these days, with EVs driving record sales and new models earning rave reviews from the automotive press. Even in that company the IONIQ 6 stands out, with up to 338 miles of EPA-rated range and lickety-quick 350 kW charging available to make road tripping easy – especially now that the aerodynamically efficient IONIQ 6 has Supercharger access through a NACS adapter (the 2026 “facelift” models get a NACS port as standard).
Once upon a time, Mrs. Jo Borrás and I were shopping three-row SUVs and found ourselves genuinely drawn to the then-new Model X. Back then it was the only three-row EV on the market, but it wasn’t Elon’s antics or access to charging, or even the Model X’s premium pricing that squirreled the deal. It was the stupid doors.
We went with the similarly new Volvo XC90 T8 in denim blue, and followed up the big PHEV with a second, three years later, in Osmium Gray. When it’s time to replace this one, you can just about bet your house that the new 510 hp EX90 with 310 miles of all-electric range will be near the top of the shopping list.
The sporty EV6 GT made its global debut by drag racing some of the fastest ICE-powered cars of the day, including a Lamborghini, Mercedes-AMG GT, a Porsche, even a turbocharged Ferrari – and it beat the pants off ’em. Combine supercar-baiting speed with an accessible price tag, NACS accessibility, $10,000 in customer cash on remaining 2024 models ($3,000 on 2025s) and just a hint of Lancia Stratos in the styling, the EV6 is tough to beat.
If you disagree with that statement and feel like driving a new Tesla Cybertruck is the key to happiness, I’m not sure an equally ostentatious GMC Hummer EV or more subtle Rivian R1T will help you scratch that particular itch – but maybe therapy might!

Komatsu-Dimag mobile charger at work; rendering via ChatGPT.
There’s no question that electric construction equipment is safer, more precise, and generally better than the diesel equipment it’s replacing, but getting power to that equipment remains a logistical challenge that hasn’t been solved for. With this new mobile Megawatt charging station, however, Komatsu think they’ve found a solution — with up to 6 MW of power!
Developed by Tesla co-founder Ian Wright, Dimaag, and Japanese equipment giant Komatsu, the groundbreaking Mobile Megawatt Charging System (MWCS) promises to bring electricity where it’s needed, anywhere on the job site, then quickly dispense enough energy to get the electric machines under its care back up and running.
And, with Megawatt power delivery on tap, the new Komatsu-Dimaag MWCS can power up equipment assets between shift changes — if it even takes that long!

The MWCS boasts a compact, high-efficiency DC-DC converter and a long-life, high-discharge-rate Battery Energy Storage System (BESS) on board that can be connected to a DC fast charger itself, or get “trickle charged” between shifts. Both the battery and its control systems make use of an advanced thermal management solution that Komatsu and Dimaag say optimizes both safety and battery life during high-power delivery.
To make sure the MWCS can get all that power where it needs to, wherever it needs to, the machine is equipped with with stout, construction-grade AT tires, 4-wheel drive, and 4-wheel steering to navigate tight surroundings and rough terrains that other solutions wouldn’t be able to get to. And, while it isn’t mentioned in the press release, there’s a common sense idea here that you could, in a pinch, use the MWCS to tow less capable vehicles out of the mud and snow, if needed.
For their part, it seems like the people at Dimaag are pretty happy with the results. “Dimaag is excited to collaborate with Komatsu, introducing our advanced ESS and DC-DC architecture to revolutionize electrification in construction,” stated Ian Wright, VP Engineering at Dimaag. “Off-road vehicle electrification demands practical solutions that not only meet but exceed the performance of equivalent large diesel engine vehicles, while also providing substantial Total Cost of Ownership (TCO) savings. Dimaag’s electrification and high-power megawatt charging systems are designed to achieve this.”
The prototype MWCS shown, above, features a 295 kWh battery pack and an MCS connector delivering up to 1,500 amps and 1,000 volts of power. Komatsu envisions a scenario wherein the mobile charger makes its rounds on the job site charging up equipment and heading back to grid power (if available) to charge itself.
Conceptually similar to the mobile power platform being developed by American firm Dannar, this new mobile Megawatt charging unit has some heavy-hitting names behind it that make it impossible to ignore. Combine that with Komatsu’s ever-increasing push towards full electrification (the two machines shown, above, are all-new in the last 60 days, with more to come) and it really feels like the MWCS is going to be A Real Thing™️somewhat sooner than later.
