There’s something deeply British about trying to go absurdly fast in something that looks like it escaped from a kid’s downhill derby. The Bluebird Aero is exactly that kind of beautifully unhinged machine: a jet-powered, composite-tubbed, 47-kilogram projectile built by a tiny team of engineers who think 100 mph is a reasonable target for something that barely weighs more than a sack of cement.

This is not a car in the way we normally use the word. It has no engine in the traditional sense, no drivetrain, no gears, and no illusions about being practical. It’s a land-speed record weapon, inspired by the legendary Bluebird machines of Malcolm and Donald Campbell, scaled down to soapbox size but infused with aerospace thinking.

At the center of it all is Russell Annison, a veteran of the Bloodhound land-speed-record project and a former Lola wind-tunnel specialist. Alongside CAD wizard and driver Matt Sadler and brakes guru Adam Rogers, Annison has created something that looks simple but is anything but. The Aero’s carbon-fiber and aluminum-honeycomb monocoque traces its lineage directly back to a Lola gravity racer built for the Goodwood Festival of Speed in 2013. That car was all about minimal drag, and the Aero inherits that obsession.

With a drag coefficient of just 0.22 and an ultra-small frontal area, the Bluebird Aero cheats the air like a racing bullet. Which is a good thing, because its propulsion comes from something equally ridiculous: a 2.8-kilogram gas-turbine jet engine built by JetCat, a German firm better known for powering radio-controlled model aircraft. Spinning at up to 123,000 rpm and delivering 17 kilograms of thrust, the little turbine fires a 700-mph jet stream out the back. It’s loud, violent, and wildly inappropriate—and that’s the point.

In May 2024, Annison strapped himself into the Aero and set a record at 55 mph for a prototype dual-propulsion electric-and-jet vehicle. Even more impressive than the number was the way it got there: the car was still accelerating after the jet was shut down, proof that the aero efficiency is doing some of the heavy lifting.

Now the team wants nearly double the speed. With new 3D-printed dive planes increasing front-end downforce under braking, Annison believes the power is already there for a near-100-mph run. The real enemies now are stability and tires. Yes—tires. The Aero currently rides on Schwalbe bicycle rubber, which is very good at being round but not so great at being asked to survive speeds normally reserved for highway traffic.

Under the skin, the Aero is an engineering jewel box. The bicycle-sourced disc brakes are water-spray cooled. The fuel tank is a bespoke welded aluminum unit. The low-pressure fuel system is designed specifically to reduce fire risk in what is, essentially, a rolling jet engine wrapped in carbon fiber.

If everything aligns, the team hopes to make another run in May—exactly two years after their last record. That timing isn’t accidental. It would coincide with the long-awaited return of Donald Campbell’s restored Bluebird K7 jet hydroplane to Coniston Water, the site of his fatal 1967 attempt to exceed 300 mph. In other words, it would be a week where British speed history gets a very loud encore.

But the Bluebird Aero isn’t just about one team grabbing one number. Annison wants to turn this into a competition. His goal is to challenge students and young engineers to build their own rival micro-record cars and go after the mark. The Aero itself already travels to schools as a rolling STEM ambassador—a 100-mph physics lesson with a jet engine.

In an era when the car industry is increasingly about software, subscriptions, and sterile efficiency, the Bluebird Aero is a reminder of something more visceral: speed as a pure engineering problem. How light can you go? How clean can you slice the air? And how fast can you make something that, on paper, shouldn’t even exist?

A 100-mph soapbox shouldn’t make sense. That’s exactly why it does.
