What defines a crazy car? Boatloads of power? Über flamboyant styling? Enormous wheel arches or towering rear wings? Extravagant feats of engineering? Or is it just something that is so bonkers mad that driving one would take nerves of steel, or enormous guts? Here we have some concepts that might just fit the bill. Not just in terms of styling, but as an overall package, these are some seriously crazy cars. And we love them.

Nissan Juke-R 2.0

Chances are, you’ve seen this car on the internet before. Or at least some bit of it looks familiar. As the name implies, the Juke-R 2.0 is the second iteration of the insane GT-R powered crossover. Only this time, they’ve bumped the power from the previous Juke-R’s 485hp to an insane 600hp in version 2.0. With a reported 23 of these Juke-Rs’ handmade by the boffins at Nissan for roughly half a million quid (little over a million Singapore dollars) apiece, the Juke-R is still way out of reach for us mere mortals. And while it may be more than a concept, it is far from being a production car.

Volkswagen Golf GTI W12-650

Who would’ve thought that fitting a bi-turbo W12 engine into a Golf was a good idea? Some guys at VW apparently, who we have to thank for coming up with the Golf GTI W12-650. Sounds like a product serial number, we know. But with 650hp and a 0-100km/h time of just 3.7 seconds, this “product” is essentially a one-off, never to be produced again. We shudder at the thought of driving this monstrosity, but we can’t help but wish we were behind the wheel.

Jaguar C-X75

She’s a looker, isn’t she? Ladies and Gentlemen, this is the Jaguar C-X75. Sadly, it never saw the light of day, apart from a few test mules and a brief appearance in a Bond film. As a concept though, it sounded promising. The C-X75 was intended to have four electric motors, pushing 194hp at every wheel, for a grand total of 780hp. All of that was to be powered by two micro gas turbines. The concept was later changed to adopt a small forced-induction engine and just two electric motors. Alas, that concept never made it to production either. Shame, we would’ve loved to have a go in it.
