A photograph posted to r/saab set the community in motion. The caption was minimal – If you’re in or around Michigan, stop by the Sloan Museum of Discovery – and the images showed a white two-seater with no doors, no A-pillars, and a cockpit canopy that belongs on a jet fighter rather than a public road. Within hours, the thread was running. Within days, Swedish automotive journalists were making phone calls.
What the photographs showed was a Saab Aero X. Not a reproduction. Not a scale model. The actual car – or rather, one of two actual cars – that Saab and GM presented to the world at the 2006 Geneva Motor Show and then, as far as the enthusiast community could determine, allowed to disappear entirely. One example has been on display at the Saab Car Museum in Trollhättan since the brand’s collapse. The other had not been publicly seen in twenty years. It turns out General Motors had been quietly holding it the whole time, deep in storage in the automotive heartland of Michigan – and it has now been returned to the light.

A Brief for the Bold
The Aero X began as a question. In early 2005, Bryan Nesbitt – then Executive Director of Design for GM Europe, and today GM’s Senior Vice President of Global Design – assembled an advanced design team of fifteen in Gothenburg and posed it directly: what would happen if an entire car was dedicated to expressing Saab’s heritage in a completely new way? The question was not rhetorical. Nesbitt wanted a design language that was bolder and more distinctive than anything Saab had produced under GM ownership, and he wanted it demonstrated without compromise.
Project leader Anthony Lo and Nesbitt identified two directions within the first two weeks – a compact sports car and a larger sports coupe – and the larger theme, a front-engined supercar form, was selected and committed to full-scale within a fortnight of that. The pace was remarkable. The exterior was led by principal designer Alex Daniel; the interior concept came from a sketch by Erik Rokke. The physical car was constructed in Turin by Italian coachbuilder G-Studio, working from scan data taken from the clay model, with Saab designers making regular visits as the prototype took shape. Fourteen months, blank sheet to Geneva debut.
What It Was
The Aero X carries a 2.8-liter twin-turbocharged V6 running on pure bioethanol, rated at 400 hp with 500 Nm of torque. All-wheel drive, a seven-speed paddle-shifted transmission, and a projected 0–100 km/h time of 4.9 seconds – with a top speed electronically limited to 250 km/h. The body is carbon fiber, the claimed weight 1,500 kg.
None of that is what people remember. What people remember is the entrance. There are no doors and no windshield pillars. The entire upper structure – roof and windscreen as a single unified canopy – lifts forward on an articulated linkage, as it does on a combat aircraft, giving the occupants a 180-degree field of view and making entry and exit from the low cabin more straightforward than it appears. Inside, conventional instruments were replaced by etched acrylic panels – the Clear Zones – displaying data in 3D graphics inspired by Swedish precision glass manufacturing. All lighting was LED throughout, at a time when that was genuinely forward-looking in an automobile.
The turbine-bladed alloy wheels, designed by Alex Daniel, were not a styling exercise. They were engineered to actively extract heat from the brake assemblies – a function-first solution wearing an aviation costume, which is the Saab design philosophy stated in physical form.
Anthony Lo summarized the intention at the time: the Aero X was about tipping the balance away from Saab’s habitual understatement, toward something more self-expressive and more assertive, while remaining entirely grounded in what the brand actually was.
Geneva, and What Followed
The Aero X was unveiled on the evening of February 28, 2006, at GM’s Premiere Night ahead of the Geneva Motor Show, surrounded by sixty tons of ice blocks arranged to evoke the Scandinavian context of its origins. It was the undisputed talking point of the show. Autocar awarded it Concept Car of the Year – the publication’s editor Chas Hallett noting that the Aero X took Saab’s familiar design vocabulary and demonstrated how it could be integrated into a modern, credible automotive architecture, including in a 400-horsepower super-coupe. Nesbitt accepted on Saab’s behalf and declared the Aero X to be something more than a concept car – a statement of where Saab’s design was heading.
It headed, instead, into storage. Saab filed for bankruptcy in December 2011. The running prototype eventually found its home in Trollhättan. The other car – the earlier of the two – went quiet.
Two Cars, Two Fates
Understanding what the Sloan Museum actually has requires understanding how the Aero X program worked. A member of the museum staff who was directly involved in preparing the car for display explained it plainly in a post that circulated through the Saab community: “This Model was the GM Design final rendition before the fully functioning concept car was constructed, which I believe is now in the Trollhättan museum. Deep within General Motors storage, this Aero X Model sat since its show circuit debut and now it will be on display at the Sloan museum.”
The Sloan car is a show model – a foam and composite construction built to the finished exterior specification and capable of rolling and steering, but without a functioning drivetrain, without the operational canopy mechanism, and without the BioPower V6. It is, in the terminology of the industry, a non-runner: the physical proof-of-concept that preceded the working prototype. It traveled the show circuit in 2006 alongside or in place of the fully operational car, then returned to GM’s collections and remained there, unseen by the public, for the better part of two decades.
The museum’s own listing confirms the status directly: “This current featured concept car has not been seen publicly since 2006.”
The Trollhättan car is the one that runs. The Flint car is the one that showed it was possible.
The Museum
The Sloan Museum of Discovery sits within Flint’s Cultural Center, named for Alfred P. Sloan, the longtime General Motors chief executive whose legacy is inseparable from the industrial history of the city. Its Durant Historic Vehicle Gallery houses over 130 vehicles connected to Genesee County and the broader GM story. The museum completed a major expansion and reopening in July 2022, emerging from a lengthy renovation at 107,000 square feet with multiple interactive galleries. The Aero X is listed within the Durant gallery, displayed beneath a projected image of the Saab 9-X concept on the gallery wall – a GM Concept Car banner overhead, the turbine wheels intact, the Saab griffin badge at the center of each rim.
When exactly the Aero X entered the collection as a display piece rather than a storage item is not formally documented. The staff account suggests it was brought out specifically for this presentation, after years dormant in GM’s inventory. Nobody announced it. It was simply there, one day, for whoever happened to walk in.
The Man Who Recognized It
When the Reddit photographs circulated, Swedish automotive publication Carup.se contacted Ola Persson to get an authoritative read on what was actually being shown. They chose the right person. Persson is among the most knowledgeable Saab voices in Scandinavia on the subject of the Aero X – and he has a more personal relationship with the car than most. In his garage in Borensberg, Östergötland, he is building a full replica of the Aero X from scratch, beginning with a styrofoam form study before progressing to a road-usable car that drives and sounds like a Saab. The entire build is documented on his Instagram account @olas_prototyp_garage, where followers from across the international Saab community have tracked the project with enthusiasm that Persson himself describes as somewhat beyond what he expected.

His assessment of the Sloan car was careful but direct: almost certainly the first prototype, the one the community had been unable to account for, held by GM throughout the two decades since Geneva. He acknowledged he could not be completely certain. The forum confirmation from the museum’s own staff, however, leaves little room for doubt about the car’s fundamental character – a show model, not a runner, preserved and now returned to visibility for the first time since the Aero X toured the auto show circuit nineteen years ago.
What Remains
Anthony Lo left GM and later moved to Ford as Global Design Vice President. Bryan Nesbitt, who posed the original question in Gothenburg in January 2005, is now GM’s Senior Vice President of Global Design. The car he commissioned as a vision statement for a brand that no longer exists is on display in the city where he works.
The Saab Aero X was never intended for production. That was understood from the outset. It was a direction-setter, a declaration of possibility, a document of what Saab could have become if the circumstances had been different. What it became instead was something rarer: a design so resolved and so coherent that its influence traveled well beyond the brand that created it, and well beyond the designers who drew it. The canopy entrance, the turbine wheels, the insistence that aviation heritage could be literal rather than metaphorical – these ideas did not disappear with Saab. They migrated.
Now both cars are visible to anyone who wants to find them. One requires a trip to western Sweden. The other requires a trip to Flint, Michigan, where it has been waiting, in the dark, for twenty years.
If you’re in or around around Michigan, stop by the Sloane Museum of Discovery.

A Reddit post found it. That feels entirely appropriate.
It seems like GM is proud of Saab after all…
Its a roling chassis it didn’t have an engine for so far i know.
Well, Bob Lutz, A Silly Brand – Bob Lutz on why GM buried Saab. A car brand that didn’t deserve a chief technology officer whose only interest was smoking Havana cigars and talking nonsense.
GM is the place where car marques go to die. It’s been that way since Billy Durant started the company. GM also has a long time policy of destroying show cars and prototypes. If I was a betting person I’d put money down that this car will never see the light of day again. It was 1986 when the end began and GM bought a half interest in the company.
Great design. Strong profile!
Build it 😀
That car looks like a big winner to me
General Motors SAABS, are nothing like the Swedish SAABs that we used to pick up off the boats at a dock in Baltimore in the 70s.
That is true – the GM SAABS run well, don’t have electrical issues and were ‘fixable’ if anything went wrong nearly anywhere in the country. Did they lack the ‘funk’ or character of the earlier cars? Probably to an extent, but they were much better vehicles.
The last couple of generations of the 9.3 sedan were the best small sedans in the world. Period.
