When you think of a country that's produced crazy supercars, the United Kingdom might not be the first country you think of. But, the Brits have proven more than a few times that they're capable of unleashing the crazy and creating spectacular supercars with insane specifications.While we may all know about cars like the McLaren F1 and the Jaguar XJ220, some other, less-known British creations could make your jaw drop even more. One of those is a car built in the 1970s by a niche manufacturer owned by an eccentric businessman. It was unusual in almost every single way, and it reportedly had enough power to keep up with some of the fastest cars of the day. The Panther Six Is One Of The Craziest Supercars Ever Produced BonhamsThe Panther Six just might be one of the craziest supercars that's ever been made. Thought up by Panther's eccentric founder, Robert Jankel, he wanted to create the ultimate road car. While he'd had a decent amount of success making retro-styled cars for the nouveau riche, that's not what he entirely wanted to do with the Panther brand. His main customers may have loved the chintzy styling of the Panther DeVille (later made famous as the car driven by classic Disney villain Cruella DeVil), but Jankel actually wanted to make something properly modern with cutting-edge ideas. He put that philosophy into action when he created the Six.Bonhams The first thing you notice is that the Six looks remarkably contemporary for a Panther. Its squared-off lines and pop-up headlights fit right in with the more futuristic design trends concept cars were sporting during the 1970s. Unlike other Panthers, the Six was mid-engined, with the engine mounted just behind where the seats were. Strikingly, it was also a convertible. The only real shared bit of Panther that the Six has with other models is the interior. Much of it is very old-school in the classic Panther fashion, with plenty of wood and leather and gold-rimmed gauges that look more like they should be on a car from the 1930s than a car from the 1970s.Bonhams The real thing that everyone points out about this car, though, is that it has 6 wheels. That's where the "Six" in the Panther Six's name comes from, and it really makes this car stand out. The front wheels are much smaller than the rears, and there are two sets of them. Both sets of front wheels steered, something which you easily got to see in photos of the Six from the time. Its Engine Was Massive And Massively Powerful Bonhams Perhaps the most impressive thing about the Panther Six, though, is its engine. It was an 8.2-liter Cadillac V8, which still to this day, is the largest-displacement production V8. This V8 was typically found in more genteel cars such as the Cadillac Eldorado of the 1970s. But, Robert Jankel saw some serious performance potential in this engine. He decided to have it heavily modified, fitting it with twin turbochargers.Exact figures aren't known, but Panther claimed that this massive twin-turbocharged V8 could produce over 600 hp. Panther also claimed that this would be able to take the Six up to a top speed of 200 mph, but it seems like this was never tested. All that power went through a (surprisingly fairly normal!) 3-speed automatic transmission. It Was Inspired By The Tyrrell P34 Formula 1 Car As you might expect, cars with 6 wheels don't come around very often. When they do, it causes a stir. It also makes you wonder where the idea for it was taken from. Well, in the case of the Panther Six, the idea for it to have two small wheels at the front was taken from a legendary Formula 1 car! That car was the Tyrrell P34, and it had a short-lived but massive impact in the world of motorsport.The Tyrrell P34 had 6 wheels because Tyrrell's engineers found a very clever aerodynamic hack. By having two sets of smaller front wheels instead of one bigger set, they could place the front wheels entirely behind the front wing. This meant that the tyres didn't get in the way of the airflow coming off the front wing. That reduced the Tyrrell P34's drag, and also had the effect of easing the airflow over the rear wing.The Tyrrell P34 was actually a pretty successful F1 car at first. It had great results in the 1976 season, getting a race win and multiple podiums in the hands of future world champion Jody Scheckter and Patrick Depailler. But, rules changed for 1977, and those changes ruined the P34's competitive advantage. It was retired after that season, and Tyrrell went back to making regular four-wheeled F1 cars. Only 2 Panther Sixes Were Ever Produced Bonhams Robert Jankel intended the Panther Six to be a proper production car, sitting at the top of the lineup of his Panther models. But, that wasn't really to be. Only two Panther Sixes were ever made. The second of the two cars wasn't even finished by the time the Panther company went into liquidation, either. It was assembled from parts after that, and it was slightly cosmetically different from the first car.Bonhams Why did the Six never get beyond two completed cars? Well, it's all to do with what happened with the company post-bankruptcy. While Panther was financially saved by the South Korean company SsangYong, its new owners didn't seem to be interested in the Six. SsangYong saw more value in Panther's retro-styled cars, such as the DeVille and the Kallista. It also wanted Panther to build a more conventional sports car with modern styling. That modern-looking sports car ended up being the Panther Solo. This was a small, fiberglass-bodied mid-engined car that used engines derived from the Ford Fiesta XR2 (in the Solo 1) and the Ford Sierra RS Cosworth (in the Solo 2). Any ambitions of Panther producing a genuine supercar were long gone. What Happened To The Only Panther Sixes Built? For those who know about the Panther Six and the story behind it, there's one question many of them have asked over the years. What actually happened to the only two Sixes ever made? That was something nobody could reliably answer for years. Well, that is, until YouTuber Oscar's Garage (linked above) tried to track the two Sixes down and find out what really happened to them. He found out that both cars have had a pretty incredible history since they were built, and one of the cars had taken a bit of an odyssey across the world! The First Car's Trail Has Gone Cold The first car (the one that was sent to all the press and motor shows around the time the Six was being launched) seems to have ended up in the possession of Robert Jankel himself for a while. Oscar's Garage managed to work this out by finding out that this Six had been registered for a short time under a private plate that was owned by Jankel. It then reverted to a more conventional registration plate, and the trail ended up going cold after 2006. That year is where the last record of any legal documentation or registration relating to that car appears. There have always been rumours that the first car ended up going out to Saudi Arabia, but Oscar's Garage didn't manage to find any concrete evidence for that.
