Flying cars have been “five years away” for about two decades now. Every CES, every Paris Air Show, somebody rolls out a tilt-rotor prototype, promises an air taxi by 2025, and then quietly disappears once the battery math catches up with the marketing department. The lithium-ion packs that work fine in a Model Y simply don’t carry enough energy per kilogram to lift a two-seater, hover it for any useful amount of time, and set it back down without the kind of incident that ends a company.<\/p>\n
But something is happening behind the scenes at the handful of eVTOL outfits that have actually made it to a production line. They’ve quietly converged on the same answer to the energy-density problem, and it isn’t a clever motor or a lighter airframe. It’s a battery chemistry the automotive industry has been chasing for a decade and still hasn’t cracked at scale: solid-state. And according to one of the few companies already rolling airframes off an assembly line, you can’t get a commercial flying car without it.<\/p>\n
The clearest statement so far comes from GAC’s low-altitude mobility arm, Govy, which started production of its AirCab two-seater last month. In an interview with the Chinese business outlet Yicai, the brand’s founder and CEO, Su Qingpeng, called solid-state cells the “essential path” for the sector and said the chemistry is simply indispensable to the industry. He framed it less as an upgrade and more as the gating item for any of this becoming a real business.<\/p>\n
That’s a notable thing to say out loud, because Govy has skin in the game. GAC started taking AirCab reservations in 2025, and the first unit came off the line on May 29, with the company now aiming for Type Certification before year-end and Production Certification in the first six months of 2027. Telling investors that your headline product needs a battery chemistry nobody currently mass-produces is either honesty or a hedge, and given that Su was speaking to a market that increasingly wants delivery numbers rather than slide decks, it reads like honesty.<\/p>\n
The physics here aren’t subtle. A car burns most of its battery fighting rolling resistance and aero drag at highway speed. A multi-rotor eVTOL like the AirCab spends a huge fraction of its energy budget just staying in the air, which means every extra kilogram of pack you bolt on costs you range twice over: once to lift the mass, then again to keep it up there. The best lithium-ion cells today top out around 250 to 300 Wh\/kg, and the pack lands lower once you add the housing, the cooling and the structure. That’s enough to hover a small aircraft for a few minutes, and not enough to do useful intercity work.<\/p>\n
Govy’s own numbers show the squeeze. The AirCab that just entered production manages about 30 km on its cylindrical lithium pack, which is fine for low-altitude tourism hops around the Greater Bay Area and not much else. The longer-range AirJet, the composite-wing sibling Govy showed back in 2024, is rated at over 200 km on current chemistry. According to GAC’s own launch materials<\/a>, future versions running the company’s solid-state cells could push that to 400 km, a doubling that nothing else in the toolbox delivers without rewriting thermodynamics. For context, we’ve covered elsewhere how solid-state can roughly double the energy density<\/a> of today’s lithium-ion in the same weight.<\/p>\n Here’s the bit that flips the conventional wisdom. Everybody assumes solid-state lands in cars first, because that’s where the volume is. Su’s argument runs the other way. Carmakers want solid-state to shave costs and squeeze a few more miles out of a $35,000 sedan. Flying-car builders aren’t trying to win a price war. They’re trying to lift a fuselage off the ground without melting it, and when the airframe itself runs into six figures, paying a hefty premium for a higher-density, less flammable cell is a rounding error.<\/p>\n Su put real numbers on that. Building an aircraft, by his account, costs 50 to 100 times what it costs to build a car, which gives flying-car makers a far higher tolerance for an expensive component than any mass-market automaker will ever have. Even small-batch solid-state production pencils out for an eVTOL today. It does not pencil out for a sedan.<\/p>\n The safety case matters even more than the energy one. Thermal runaway in a parked car in a garage is bad. Thermal runaway in something hovering 300 feet above downtown is a regulatory event that ends the entire industry. Solid electrolytes don’t carry the flammable liquid that turns a punctured pouch cell into a flamethrower, which is exactly the risk profile an airworthiness regulator wants to see before it stamps a Type Certificate. So eVTOL gets to be the early customer that subsidizes the chemistry’s awkward, expensive adolescence. Limited-run aircraft can absorb the cost; once volume scales and prices fall, the same cells trickle down into ground EVs. It’s the reverse of how aviation usually borrows from the car world.<\/p>\n Su’s comparison to the early EV market is the part worth chewing on. He pointed to a specific inflection point: new-energy vehicles didn’t enter their real growth phase until their market share cleared 7%. Below that line, EVs were a curiosity. Above it, the cost curve, the charging network and consumer habits compounded into something that ate the incumbent market alive. His bet is that aerial mobility runs the same S-curve, only faster, once the chemistry is in place and the certifications clear.<\/p>\n That’s where the dates come from. Su pegs the real start of commercial manned eVTOLs at 2027, the industry’s “first year” in his telling, and pencils in a self-sustaining commercial ecosystem by 2030, which lines up with what most rivals are saying publicly and, conveniently, with the timeline solid-state suppliers give for serious capacity. He isn’t promising the early ramp will be quick, though. He expects flying cars to scale slower than ordinary automobiles, because the airworthiness regime demands constant iteration, continuous verification and brutal manufacturing validation. Translation: nobody gets to fail publicly at Cybertruck volumes, because the certification process won’t let them.<\/p>\n The other shift Su flagged is on the money side. For most of the last decade, eVTOL pitches sold themselves on top speed, range slides and concept renders. That era is ending. Capital is now asking the boring questions. How many airframes did you actually deliver, how close are you to a Type Certificate, is the factory running, can you do this without burning a billion dollars a year. It’s the same conversation the EV sector had around 2018, when Wall Street stopped accepting “we’ll figure out the unit economics later” as an answer.<\/p>\n That changes who gets funded. A flying-car company that can point to a real solid-state supply deal and a factory that can bolt the packs in is a far easier sell than one waving a 2019-era render. The AirCab itself shows the demand is there: it pulled in close to 1,000 advance reservations at its Hong Kong debut<\/a> in June 2025, and GAC says the order book has since climbed toward 2,000, at a guide price capped at 1.68 million yuan, around $233,000. That’s not iPhone money, but it’s the kind of order book that justifies committing to a premium battery supply.<\/p>\n Most readers are not in the market for an AirCab. Fine. The reason it matters to ground EVs is that aviation is about to become the demand-pull customer solid-state suppliers have been waiting for. Carmakers keep promising solid-state in production cars and keep pushing the date right. Toyota, Nissan, Stellantis and BMW have all talked up solid-state for production vehicles<\/a> and all kept nudging the timeline. The chemistry is hard, the manufacturing tolerances are unforgiving, and the cost case doesn’t close at $30,000-a-car volumes.<\/p>\n Flying cars are the customer that doesn’t care about the cost case yet. If Govy and its peers really do absorb the first few years of low-volume, high-cost solid-state production, the suppliers get the cycles they need to learn the process. By the time the chemistry shows up in the next wave of EV battery tech<\/a>, it’ll have been hovering over Guangzhou for a few years already. The flying-car industry has promised the future for 20 years and mostly delivered vaporware. This time, the reason it might actually arrive is the same reason your next EV might finally get a battery that doesn’t catch fire. Both halves of that story, it turns out, run through the same supplier.<\/p>\n","protected":false},"excerpt":{"rendered":" Flying car maker GAC Govy says solid-state batteries are the only chemistry that gets eVTOLs into commercial service.
