Top 10 Cars with the Weirdest Concept Designs (That Almost Happened)

1. Renault Espace F1 - The Minivan That Wanted to Be an F1 Car

Right, so imagine this: you're running late to football training at Heaton Moor Park, and your mum’s driving you there in a bog-standard Renault Espace. Comfortable, sure. Loads of space. But nothing exciting, right? Now picture the exact same car... with a 3.5-litre V10 engine from a Formula 1 car jammed into it. Yeah. That happened. Well, sort of. Renault decided to take their sensible family car-the Espace-and turn it into a bonkers speed machine. The thing had over 800 horsepower and could do 0-60 faster than most Ferraris. It was basically the car version of your grandad showing up to a retirement party doing backflips. Totally unexpected. But here’s the twist: it never went on sale. Renault built just one, and that was it. Probably for the best, to be fair. Can you imagine someone trying to reverse-park that outside the Asda in Stockport? Absolute chaos. Still, the idea behind it was kind of brilliant. Take something boring, make it mad. It’s the car equivalent of putting a rocket engine on your nan’s mobility scooter. Not practical, but you can’t look away. At Dace Motor Company, we see all kinds of cars come through our showrooms in Stockport and Manchester, but nothing quite like this. The Espace F1 remains one of those wild “what if” moments in car history.

2. BMW GINA - The Car with Skin

Alright, this one’s a bit creepy. BMW made a concept car called the GINA. And instead of metal panels like every other car on Earth, they covered it in fabric. Not your average curtain-fabric either-this stuff was stretchable, water-resistant, and weirdly alive-looking. Like, you’d touch the bonnet, and it would flex. You turn on the headlights, and the “skin” opens up like eyelids. Honestly, it felt like something you'd see outside the Trafford Centre on Halloween. The whole idea was about flexibility. BMW said they wanted the car to “change shape” depending on what the driver needed. So the body would literally move and morph. Mad, right? And okay, we get it. It was never meant to be mass-produced, but still-fabric on a car? In Manchester? With all the rain we get? You’d spend half your life trying to dry it out. Still, credit where it's due. BMW tried something different. A bit of outside-the-box thinking. But we’ll stick with metal, thanks. If you want something reliable and not... gooey, come have a look at the used BMWs at our German Car Centre in Stockport. No stretchy fabric-just proper cars.

3. Mercedes-Benz F 015 - The Sci-Fi Sofa on Wheels

The F 015 looked like it drove straight off the set of a sci-fi film. The idea was that it would drive itself, and you could sit inside facing your mates, chatting away like you were in a living room. Yeah, no steering wheel. Just seats that spun around, big screens everywhere, and doors that opened like something out of Star Trek. It was meant to be the future of luxury. And to be fair, it did look comfy. Like you’d want to watch Netflix in it rather than drive it through rush hour on the M60. Mercedes showed it off with loads of flash, but let’s be honest-it wasn’t really meant for daily use. Especially not on the roads round Stockport where you’re dodging potholes the size of your head. You know how when you get on a tram in Manchester and try to sit down without sliding into someone’s lap? That’s how we imagine this would feel going around corners. We get loads of proper Mercs at our showrooms. Ones that actually make sense. But this one? More like an expensive science experiment. Cool to look at though.

4. Chrysler ME Four-Twelve - The American Supercar That Disappeared

Now this one’s just frustrating. Chrysler-yes, the company best known for making big family cars-decided to go full mental and build a supercar. And it actually looked amazing. The ME Four-Twelve had a 6.0-litre V12 engine, went like a rocket, and was quicker than most Lamborghinis at the time. The name even stood for Mid-Engine, Four turbochargers, Twelve cylinders. Simple, but menacing. Thing is, it never made it to production. Chrysler showed it off, everyone went “Ooh,” and then… nothing. Just a one-off prototype that now lives in a museum somewhere collecting dust. You’ve got to admire the ambition, though. It’s like Greggs suddenly announcing they’re making gourmet sushi. Bold move, probably not happening, but we’d all want to see it anyway. If you’re after speed that actually exists in the real world, we’ve got some sporty numbers at Dace Motor Company that don’t just sit in a glass box.

5. Nissan Pivo - The Car That Could Spin on the Spot

Imagine trying to parallel park in Northern Quarter on a Saturday night. Now imagine you had a car that could just spin around on the spot like a fidget spinner. That was the Nissan Pivo. It looked like a pod from the future and came with a cabin that rotated 360 degrees. So instead of reversing? You just turned the whole cabin to face the other way. Problem solved. Sounds brilliant, right? Except it was tiny. Like, go-kart tiny. And it looked a bit like a toaster on wheels. Plus, it had more screens than a gaming setup. The Pivo was full of wild ideas-voice control, rear-facing cameras instead of mirrors, and a robot “assistant” that would talk to you. Kinda cute, kinda creepy. Not something you'd want giving you directions through Cheetham Hill. It never went into production, which is probably for the best. But as ideas go? Not half bad. Maybe someone will bring it back one day with less weirdness and more boot space.

6. Citroën Karin - The Pyramid Car

This one’s just bizarre. Citroën made a concept car that looked like a slice of Toblerone on wheels. Called the Karin, it had sharp angles, a super flat roof, and enough glass to make it feel like a greenhouse. And get this: it only had three seats. One in the middle front (for the driver), and two behind. Like a weird reverse tricycle. It never saw production, obviously. Mainly because it looked completely bonkers. Like something you'd make out of cardboard for a school project. But it was a bold move from Citroën. Even now, their designs can be a bit out there. If you’ve ever driven a C4 Cactus, you’ll know what we mean. Still, they’ve dialled things down these days, and we’ve got plenty of sensible Citroëns at our showrooms. Ones you can actually fit in a parking space.

7. Toyota Pod - The Car That Changed Moods

Now this one's straight out of a Black Mirror episode. Toyota made a concept car called the Pod that could sense your mood. If you were feeling sad, the car would try to cheer you up. How? No idea. Maybe by changing the lights, adjusting the seat, or just wagging its fake antenna like a dog. We’re not making this up. The idea was to make driving more “emotionally aware.” But it did make the car look like a Pixar character. Cute, but maybe not ideal for a grown-up trying to get to work in Salford. Plus, we can’t imagine many people in Manchester wanting their car to talk back to them when they’re stuck in traffic on Deansgate. Let’s just say... we’re glad they stuck to normal Toyotas after this one. We’ve got loads of great ones at Dace that don’t try to cheer you up. They just start, drive, and don’t answer back.

8. Saab Aero-X - The Jet Fighter Car

Saab always liked their aviation references, but with the Aero-X, they took it to another level. The whole roof opened upwards like a jet cockpit. No doors. Just the whole top flipping up. You had to kind of step in and drop down into it. Not great if you’re in a tight car park outside Aldi. But man, did it look cool. The interior was clean, futuristic, and had a digital dashboard that felt like you were flying a plane rather than driving to Bury. It never went into production, mostly because Saab ran out of money. But the concept still gets talked about as one of the coolest cars that never got made. Saabs don’t come around often at our place anymore, but we always keep an eye out. You never know-something wild might pop up on our forecourt.

9. Ford Nucleon - The Nuclear-Powered Car

Yep. Nuclear. Ford once had the bright idea of building a car powered by a tiny nuclear reactor. This was back in the 1950s, when everyone thought nuclear power would solve all problems. The Ford Nucleon never got built, and for good reason. Like, where would you even refuel that? “Just popping to the petrol station and oh, by the way, don’t stand too close.” They didn’t even finish the engine part, just made a model of what it might look like. Turns out strapping radioactive material inside a family car wasn’t the best idea after all. Still, it shows how bonkers the 1950s were. People thought we’d all be flying by now. Instead, we’re just glad our cars don’t need hazmat suits.

10. Alfa Romeo BAT Cars - Like Something Out of Gotham

We’re wrapping up with the most dramatic ones-Alfa Romeo’s BAT cars. No joke, they really were called BAT. Short for Berlinetta Aerodinamica Tecnica. These things looked like Batman’s weekend ride. Giant fins, curved glass, weird noses-just full-on Italian madness. They were all about aerodynamics, and honestly, looked like they belonged in a sci-fi museum rather than on the A6 through Stockport. The thing is, they weren’t just show cars. They worked. But Alfa never mass-produced them. Probably too wild for everyday driving. That said, we do get some gorgeous Alfas through our doors at Dace Motor Company. Nothing quite as crazy as the BATs, but stylish enough to turn heads at the lights. So there you go. Ten of the strangest concept cars that nearly happened-but didn’t. Some were brilliant. Some were bonkers. But they all remind us how creative car makers can get when they’re let loose with a sketchpad and no budget limits. And if you’re after something cool-but actually real-we’ve got over 600 used cars across our four locations in Stockport and Manchester. Come and find something weird (in a good way).
