On a quiet country road in Rhode Island, she was simply hunting for a café open on Easter Sunday in 2026. Her little road trip unexpectedly turned into a field report when her companion spotted a rare Audi Coupe Quattro in black. The car sat in the tired parking lot of a small-town shop. They did a quick hairpin turn to circle back and admire this coupe, which US buyers were only able to buy in roughly 1,750 examples. Getting out of their Mazda, the Audi appeared, its paint dull and tires flat. But just a few meters away, a large white sedan, immaculate and clean, suddenly drew every eye. It looked unusually high on its wheels, according to the account shared by The Autopian.
That’s when she realized the real surprise wasn’t the Audi at all, but the white Lexus. A few months earlier, a friend had sent her a photo of an identical sedan parked in another anonymous lot. The message came with an intriguing shot: a control box with switches labeled “Jump” and “Roll.” Looking through the window, she found the same box, with its famous “Jump” button. A large screen had replaced the passenger airbag. An old Nokia phone still sat in its cradle, untouched. This grand sedan was none other than a 1994 Lexus LS400 equipped with the legendary Bose electromagnetic suspension—a prototype worth tens of millions of dollars, abandoned on a simple provincial parking lot in America.
U-turn for an Audi Coupe Quattro, a jaw-dropper: a Lexus LS400 Bose
The couple pulled up in front of the small Knighthawk Auto workshop, tucked away in Rhode Island countryside. The Audi Coupe Quattro, rare but tired, was ultimately just a pretext for this Miata-powered turn. Curiosity soon shifted toward the white Lexus, evidently raised off the ground. The gap between the original tires and the fenders was immense. It appeared “lifted,” even though the bodywork and chrome were in excellent condition. That contrast reinforced the impression that this wasn’t simply a forgotten test car but a vehicle still very much in a testing phase.
Back home, videographer Annie Keller, known online as “Automotive Annie,” posted a Reel on Instagram. Her car-obsessed followers reacted immediately, and the video racked up tens of thousands of views within twenty-four hours, then tens of thousands more. It eventually climbed into the hundreds of thousands, and today sits around 1.4 million on Instagram, with roughly 250,000 on TikTok. Annie briefly worried that the shop owner might resent the sudden exposure, given the cars were visible from the street. But a comment left by the shop’s owner would change everything. Mike invited her to come back and look at the Lexus LS400 up close. He gave her the go-ahead to film the car and the shop’s other projects, completely unreserved.
Bose Suspension: the Lexus LS400 That Jumps, Explained
For those who forgot why this Lexus LS400 is so special, the story goes back to the 1980s. Amar Bose, founder of the audio company, wanted to revolutionize car behavior. His idea was to replace springs and dampers with linear electromagnets driven by a computer at each wheel. Other automakers like Citroën or Cadillac had already flirted with sophisticated suspension ideas, but none relied on a fully electromagnetic system. After years of calculations, modeling, and testing, Bose unveiled its active suspension in 2004. It was installed on a 1994 Lexus LS400 used as a test mule. Journalists like Csaba Csere of Car and Driver captured the shift in philosophy: “All contemporary suspensions are reactive. When a wheel hits a bump or a pothole, the wheel’s movement causes the suspension to compress or extend in response. In corners, during braking and acceleration, the suspension moves the same way and lets the body roll, squat, or dive. That’s been the way since springs were added to carriages in the mid-17th century. An active suspension, by contrast, acts before the event. It has a computer that tells a powerful actuator at each wheel exactly when, in which direction, how much, and at what speed to move. The computer uses a network of sensors to gauge, for example, the car’s speed, longitudinal and lateral accelerations, and the forces acting on each wheel. It then commands the wheel to move in the ideal way for the situation. There’s no longer a compromise between comfort and handling, rough roads and smooth ones, low speeds and high speeds.”
Each wheel received an electromagnetically driven actuator offering roughly 8.5 inches of travel, about 22 centimeters. The system responded in under 10 milliseconds to information from sensors spread around the car. A 2016 viral video shows two Lexus LS400 on the same bumpy course. The stock car bounces, while Bose stays nearly perfectly flat, then literally clears a wooden beam laid on the road. The project is said to have cost around $100 million, or about €92 million. It was ultimately deemed too heavy and too expensive for mass production. The technology rights were sold in 2017 to ClearMotion. The company adapted it into an electrohydraulic version and now supplies it to the electric luxury sedan Nio ET9. It has also signed an agreement with Porsche to develop new active suspensions. On the unit found at Mike’s shop, the electromagnetic actuators had been removed before sale. They were replaced by simple metal tubes in the front and 2×4 wooden boards in the rear. That makeshift setup explains the Lexus’s extreme ground clearance on the parking lot.
A Lexus LS400 Bose Dismantled on a Parking Lot: Value and Future Uncertain
Before landing at Knighthawk Auto, this prototype had already lived several lives away from Bose’s laboratories. Three Lexus LS400s were purchased for the program. Two were converted with the Bose suspension, one remained stock for comparison. When the project stalled, the technology passed to ClearMotion. A program employee bought the sedans. He kept one LS400 in stock for driving, used one modified as a parts bank, and sold the second—the one that would end up on that Rhode Island parking lot. It surfaced on Facebook Marketplace around $2,500, roughly €2,300. The listing claimed around 80,000 kilometers on the clock and indicated that it would be difficult to reassemble original suspension. Mike found the listing while hunting for a Lexus V8 for a swap into a client’s Toyota 4Runner. He was a mechanic at the time, before he and his wife Lauryn took over Knighthawk Auto. “I thought there was no way the car could be this one. Especially given the absurdly low asking price,” he recalls.
When Annie finally visited the shop, the 1UZ-FE V8 from the Lexus LS400 had already been pulled to join the 4Runner. Under the hood, Mike still showed the stainless steel Bose torsion bars. You could also see suspension arms stamped with the Bose logo and small metal squares wired up, likely accelerometers. The four original Bose wheel covers were carefully stored away to prevent theft. Inside, the leather was nearly pristine, with almost no creasing. The scent reminded you of a nearly new luxury sedan from the 1990s. The control box with its “Jump” button remained on the center console. A screen had taken the place of the passenger airbag. Under the center armrest, Annie found a small cube engraved “Motionpak Multi-Axis Sensor.” In the trunk, a tangle of cables, batteries, and a big computing rack recalled its function as a rolling laboratory. The Nokia phone still lit up with the message “Project Sound Phone 3,” and Mike fired up a round of Snake. Annie filmed the entire scene and posted a vlog on YouTube in addition to her short videos. Her Reel kept rolling, gathering hundreds of comments and private messages asking for the car’s exact location. Among them was Freddy Hernandez, the popular YouTuber known as “Tavarish,” famous for rescuing iconic cars. Annie shared Mike’s contact. She believed there could be a path to reviving this experimental Lexus, possibly through him. Reactions online ranged from sacrilege to the logic of giving a healthy V8 a second life elsewhere. One thing was clear to the mechanic: “This isn’t going straight to the crusher,” Mike insisted. He pictured a future rescue, either something he could pull off himself or a handoff to a devoted enthusiast who would grant it a new life, even if only in a static display.
