Why It's Almost Impossible For Cars To Go 350 MPH

[00:00:00]304 mph. That's how fast Andy Wallace was going when the Bugatti went light.

[00:00:05]Not off a ramp, not on a racetrack corner, on a supposedly flat straight in Germany. At 277 mph, the front of the car went light and briefly lifted clear of the surface. For a fraction [music] of a second, a machine worth millions was moving at over four times typical highway speed. [music] And the road wasn't underneath it. It landed, the tires held, and Bugatti crossed 300 mph for the first time in history. 7 years later, nobody has officially gone faster on a two-way average in a production car. And the next barrier, 350 mph, has already consumed decades of promises, billions in development, and at least one very public fraud. Here's why 350 is so much harder than it looks. Act one, how we got here. To understand why 350 feels so far away, you need to know how long it took to get to [music] 300. In 1987, Ferrari's F40 became the first production car widely accepted to have broken 200 mph. Then it took 11 years for the next milestone. In 1998, McLaren's F1 hit 240.1 mph at Volkswagen's private test track in Germany. [music] The driver was Andy Wallace, the same man who would push Bugatti to 304 mph two decades [music] later and naturally aspirated BMW V12 at its absolute limit.

[00:01:25]After the run, the gearbox read 130° C.

[00:01:29]Wallace said they had barely 30 seconds of safe throttle time left. The McLaren F1 still holds the record for the fastest naturally aspirated production car ever built. Then came the arms race.

[00:01:41]2005 Bugatti Veyron 253.8 8 mph. 2007 SSC Ultimate Arrow 256.1 mph on a closed highway in Washington State verified by Guinness. [music] 2010 Bugatti Veyron Super Sport 267.8 mph. Each record requiring more horsepower, more tire technology, more engineering budget than the last. 2017 Koig Sega Gera RS 277.87 mph, a public highway in Nevada closed for the [music] day. A customer's personal car on standard Michelin tires.

[00:02:17]284 mph northbound, 271 southbound into a headwind and an uphill grade 2-way average 277.87.

[00:02:26][music] The most impressive part was how routine Koigseg made it look. Then August 2nd, 2019, [music] Aerlesian, Germany, VW's private test track. Andy Wallace climbs into a Bugatti Chairen prototype with a stretch tail, a roll cage, [music] and no speed limiter.

[00:02:41]304.773 mph, the first time any road car had cleared 300. [music] And then Bugatti's president announced they were done, withdrawing from the speed competition permanently. The record was theirs. They were walking away. That left three very different machines to walk through it.

[00:02:58]Act two, [music] the physics wall.

[00:03:00]Before we get to who's trying, you need to understand why 350 is so much harder than 300. Aerodynamic drag increases with the square of your speed. But the power required to push through it increases with the cube. Going from 300 to 350 mph, a 16% speed increase, requires roughly 60% more horsepower.

[00:03:19]Not a little more, roughly 60% more.

[00:03:22]Depending on a car's aerodynamics, holding 250 mph may require around 1,000 horsepower at the wheels. By 300 mph, that figure can approach 1,700.

[00:03:34]At 350, you're entering territory well above 2500. And every extra mile per hour past 300 costs you exponentially more than the last. So the engineers gave the cars more power. 1,800 horsepower. 2,000. [music] One car now claims 2,31. And 350 mph still hasn't happened because power is only one part of the problem. The harder part is the tires. For Bugatti's 304 mileph run, Michelin had to create something that had never existed before.

[00:04:05]They reinforced the tire casing with an extra layer of carbon fiber. They individually x-rayed every tire before it was fitted. [music] Then they tested each one on a space shuttle tire test rig in North Carolina, the same equipment used to certify aircraft landing gear at speed. Even then, Andy Wallace described a tearing force of 7 tons on each tire at peak speed. 7 tons per tire. At 350 mph, that force increases by roughly another third. The tire spins at over 4,400 rotations per minute. The centrifugal forces trying to tear the rubber off the rim climb to levels that current roadleal compounds cannot reliably survive. A tire failure at 350 mph doesn't mean losing control.

[00:04:48][music] The tire itself becomes a projectile. And then there's the venue.

[00:04:52]Bugatti nearly ran out of road at 304 mph. For a verified two-way run at 350, you need 12 to 15 miles of flat, smooth, closed tarmac. [music] No test track in the world is long enough. The power is theoretically achievable. The tires and the road are where it keeps falling apart. Act three, the three challengers. As of mid 2026, three machines are credible candidates for 350 mph. [music] None have a verified top speed run. All three are waiting on something different. The first is Kunigseg's Jesco Absolute, a small Swedish company that most of the world discovered when their cars started breaking records on public highways. The Absolute is their dedicated top speed [music] machine. The 5.0 L twinturbo V8 produces 1,280 horsepower on regular gasoline and 1,600 horsepower on E85 ethanol. Drag coefficient 0.278.

[00:05:50]They stripped the rear wing from the track focused version and replaced [music] it with fins because at these speeds downforce and drag are the same thing and drag is the enemy. Koigseg's simulations put the absolute somewhere between 330 and 350 mph. No top speed run has been completed. First deliveries were in 2023. As of mid 2026, Koigseg [music] says two things are blocking them. A suitable venue long enough for a verified two-way run and [music] tires.

[00:06:16]They are working with Michelin on compounds capable of handling the loads and that development is ongoing. Their 0 to 400 and back to zero sprint in 25.21 seconds verified by race logic in August 2025 proves the power is real. The road and the rubber are next. [music] The second challenger is Hennessy's Venom F5. If Koigseg is a scalpel, the Venom F5 is a sledgehammer. [music] In April 2025, Hennessy announced a 2031 horsepower evolution package from a 6.6 L twinturbo V8 developed with Ilmore, the engineering firm behind Formula 1 and Indie Cargin Engines. CFD Simulations project 328 mph. In July 2024, John Hennessy drove the F5 to 219 mph in a standing half mile. A full top speed attempt at an undisclosed US runway is something Hennessy says the team is still working toward. [music] As of mid 2026, it hasn't happened, and Hennessy has been working toward it since 2021. The third Challenger came from somewhere almost nobody in this world expected. On September 14th, 2025, at a proving ground in Poppenberg, Germany, a car called the BYD Yang Wong U 9 Extreme hit 308 miles per hour in a single direction [music] in a manufacturerbacked run with independent telemetry on site and it did it on electric motors. [music] BYD is China's largest electric vehicle company. The Yang Wong U9 Extreme is their outlier.

[00:07:43]Four electric motors, one at each wheel, producing somewhere around 3,000 horsepower [music] from a 1,200volt platform. The motors spin at 30,000 revolutions per minute. [music] The tires were customdeveloped for this specific run, rated above 310 mph, but there is a real penalty that comes with that approach. The battery pack required to feed those motors is heavy, which means more load on the tires, more heat [music] to manage, and harder physics at the extreme end. It is a different set of problems, not an absence of problems.

[00:08:15]The driver was German professional Mark Basen. [music] His comment, "This record was only possible because the U9 Extreme has incredible performance. Technically, something like this is not possible with a combustion engine. Top Gear named it their moment of the year. There is an important asterisk. The 308 mph run was a single direction. A Guinness style record requires a two-way average, so wind and grade effects cancel out. By that stricter standard, the SSC toara's two-way average of 282.9 mph still officially holds the record. The Yang Wang did 3081way.

[00:08:49]Until there is a verified return run, the scoreboard doesn't change. Act four, the controversy. Before we get to where the record actually stands, [music] there is a story that has to be told because it changed how everyone in this world verifies speed claims. October 10th, 2020. [music] SSC North America announced that their twoara hypercar had set a new production car world record on Highway 160 outside Parrump, Nevada.

[00:09:16]Two-way average 316 mph, peak oneway, 331, 331 mph on a public road in a car most people had never heard of from a company most people had never heard of.

[00:09:28]SSC released a video with GPS telemetry overlaid on the footage. Car magazines ran it. The record stood for less than three weeks. The problem started with the road itself. YouTubers and engineers who knew Highway 160 started doing math.

[00:09:43][music] Koigseg had run their Aggera RS on the exact same stretch 3 years earlier. People compared both videos, timing how long each car took to pass the same landmarks. The Touittara was visibly going slower than the Aggera RS, even though the telemetry overlay claimed it was traveling 50 mph [music] faster. Then someone noticed the GPS readout was showing over 20 mph before the car had visibly moved from a standstill. Data that physically cannot exist. The company SSC had named as their telemetry validator a firm called Duatron publicly stated they had not certified the run. Datron disowned the validation entirely. Three separate YouTube channels, including engineers with motorsport timing backgrounds, all reached the same conclusion independently. The actual peak speed was probably around 280 mph, not 331.

[00:10:33]SSC's [music] CEO Jared Shelby released a video statement admitting the footage was wrong, attributing it to video editors who had accidentally spliced two different runs together, creating a composite that showed incorrect speeds.

[00:10:47]He promised a rerun with independent witnesses. The December rerun in Florida hit heat issues and topped out at 251 mph. Then January 17th, 2021, the car's owner, a doctor named Larry Kaplan, ran the Tuittara at the Kennedy Space Center shuttle landing facility with a race logic engineer physically present.

[00:11:07][music] Two runs, 279.7 mph one way, 286.1 mph. The other, two-way average, 282.9 mph. The most widely recognized official two-way production car [music] record. A number that took a public controversy, a failed attempt, and a second attempt to finally establish. In May 2022, Kaplan returned to Kennedy Space Center and hit 295 mph in one direction before running out of runway.

[00:11:34][music] The car is capable of more. It just hasn't had enough road. Act five, the human cost. The engineering barrier of 350 mph is one thing, but at some point, a human being has to sit in the car. Craig Breedlove spent most of the 1960s in a personal war with Art Arons for the land speed record, [music] trading it back and forth in jet-powered cars at Bonavville. On October 15th, 1964, Breedlove was running his Spirit of America, chasing 500 mph. [music] He broke it 526 mph. Then on the return run, the parachutes deployed and tore away. both of them. The brakes [music] melted, the steering failed. At somewhere above 400 mph, with no way to stop and no way to steer, Breedlove shot through the shutdown zone, took out a telephone pole, launched 30 ft off an embankment, and went nose first into a brine pond. He climbed out of the water, and said, "And now, for my next act, I'm going to set myself on fire." He wasn't hurt. The skid mark stretched for 5 miles. And somehow, that wasn't even the craziest crash that decade. November 17th, 1966. Art Arons, also at Bonavville, also in a jet car. [music] His green monster was running at around 610 mph when the right front wheel bearing seized. [music] The car tumbled for over a mile. Arons walked away with cuts and bruises. Guinness recognized it as the fastest car crash ever survived.

[00:12:58]These were jet cars, vehicles built for one purpose that looked nothing like anything with a license plate. But the physics of what happens when something fails at velocity is the same whether you're in a purpose-built record car or a roadleal hypercar. [music] Andy Wallace, who drove Bugatti to 304 mph, described hitting that surface irregularity at 277 and feeling the front of the car lift. He said the run had already been called off once when a bump was found on the track. They re-examined the surface, decided it was acceptable, and went again. He felt the front go light, and kept his foot flat.

[00:13:32]That decision, keeping the throttle open when a road car briefly leaves the tarmac at nearly 280 mph, is the gap between the people who set these records and the people who watch them. Act six, where it stands. So, here's where things actually stand in mid 2026.

[00:13:49]The most widely recognized official two-way production car record is 282.9 mph. SSC Touittara, Kennedy [music] Space Center, January 2021. The highest verified single direction speed by a production car is 308 mph. BYD Yang Wang Poppenberg September 2025. One is an official record. The other is a one-way run waiting on a return pass. Three cars are theoretically capable of going beyond that. [music] One is Swedish, waiting on tires and a long enough road.

[00:14:21]One is Texan, waiting on a confirmed attempt date that has been delayed for 5 years. One is Chinese and electric and waiting to prove that 300 plus mph is repeatable in both directions, not just a one-time pass. And 350 mph remains untouched. Not because anyone tried and failed because nobody has yet had the right car, the right tires, and the right piece of road on the same day with verification [music] standing by. Malcolm Campbell crossed 300 mph in a car in 1935. It took production cars until 2019 to match that. 84 years. [music] The gap between 300 and 350 has already been open for 7.

[00:15:01]Someone is going to close it. The only question is who gets there first and whether the tires survive it? [music] Drop a comment. Koigseg gets there first, Hennessy, or does an electric car from China do it before either combustion machine? That debate is genuinely open. Hit the like if this was worth your time and subscribe if you want to be here when it actually happens. Because the moment someone [music] proves they can do it, we're breaking it down.
