The world is practically littered with failed supercar designs. From ATS to Vector, Pegaso to Bricklin and beyond, there have always been guys (and gals) who will risk it all trying to gain success in an industry almost notorious for failure. Though some such as Weismann and SSC succeed against all odds, the high majority end up as part of the losing crowd. In this industry it doesn't really seem to matter how good-looking or performing your car is, but how lucky you get seems to determine the final say. So, as 2010 draws to a close, Let's take a look at four of the supercar nameplates you will likely not be hearing from for a long time and see how they fell from fame and success.
1: Exagon Motors
Exagon Motors, a division of the French racing and tech firm Exagon Engineering, stunned press and spectators alike at this year's Paris Motor Show. It had all the right things going for it. It was fast, backed by two electric motors producing a combined 340 horsepower in a lightweight package. It was flashy, with looks that would turn heads anywhere in the world where it happened to show up. It was green, with a claimed 250-mile range from the aforementioned electric powerplants. And best of all, it was from an established and respected company. So what went wrong?
Much like Paris's constantly changing fashion scene, this Paris show car quickly became forgotten. The world obsessed over it for a day, then never again was it in our minds. This was partly the company's own fault. The news section stopped in September with news on the final round of photoshoots. Since then, no other information on the car was released, leaving journalists wondering about the simplest facts. There wasn't even any knowledge of what the car's body panels were made of. This in turn caused a lack of interest among potential investors, making the budget tight for this dream. As of right now, Exagon Engineering has made no publicized progress on the project, with work at a standstill. Hopefully it rebounds, but it is more likely to join the pile of discarded stillborn supercars.
2: Artega
Back in 2007, Henrik Fisker, the man responsible for the Aston Martin Vantage and Fisker Karma, among other so-far successful ventures, designed this little beauty for a company named Paragon Parts Group. Presented to the public at the 2008 Geneva Auto Show, it weighed less than 2,500 pounds and was motivated by a VW-sourced 300-horse V6. Meant to compete with the likes of Audi, Porsche, and Mercedes-Benz in the $100k luxury sports car league, the Artega provided a sporting edge over its potential competitors, being as quick on its feet as a Lotus with the luxury of the much more expensive car that it was. Production began briefly in 2009 and 2010, but soon the company was not selling cars. Bankrupt, Paragon Parts Group sold the concern to a Mexican firm.
Though Artega continues to sell cars in very small numbers in Europe, sales are dwindling, and the company may soon shut down with only a handful of cars and memories preserving its existence into the future.
3: Ronn Motor Company
Making its debut in Las Vegas, this monster was the last thing expected. It was a Tour de Force of technology that seemed so complex, but in reality came down to simple science. The Scorpion, as Ronn Motors named the car, utilized an Acura engine that was turbocharged to 450 horsepower, but then was fed a mixture of gas and hydrogen, which led to claimed gas mileage of 40 MPG. The Texas-based company was busy marketing the car to potential investors, but though many bit, most fell off after a while. Peaking at $6.00 a share, Ronn Motor Company stocks quickly plunged down and down, eventually coming down to the two cents it still stands at today. It's not likely that the Scorpion will be built in any large quantity, however innovative it is. While the gas/hydrogen hybrid system used here may make it into mass production vehicles eventually, the company itself is not bound for such success.
4: Devon Motorworks

Ah, the sad tale of the Devon GTX. This was the one every American car guy and girl was rooting for, and the one that broke their hearts when it didn't work out. Based loosely on the Dodge Viper, Devon Motorworks's GTX supercoupe came out of nowhere, demolishing the Mazda Raceway Laguna Seca record lap time and becoming a full-fledged company in a heartbeat. On a roll, it seemed that nothing could stop the company. It was getting major press coverage, with the cover of the duPont Registry and featured articles in many other magazines. It was featured on TV shows and blogs, and had all of America's car culture talking. Devon had a race team lined up with big-name drivers to break the Nurburgring production car record and to compete in FIA and GT2. Though some initially people dismissed the car as a reskinned Viper, even they had to admit that the transformation went much deeper than the body panels. Devon Motorworks seemed bound to become a big supercar manufacturer. But, as with many of our favorite things, something went horribly wrong.
On November 4th, 2009, Chrysler announced that it was ending the Production of the Dodge Viper in 2010. Since it wanted to keep the engineering behind the Viper safe from competitors, Chrysler did not want to sell its designs to Devon. With no base for their car and no funds to develop a whole new one, Devon had to cancel its automotive operation. Still determined to do something, the company is currently trying its hand at a variety of projects from watches to bicycles. In early 2010, a Dodge Viper ACR bested the Devon GTXs lap time at Laguna Seca, ironically signalling the end to both the Viper and GTX.
