30 Most Unusual and Innovative American Performance, Sports and Muscle Cars

27. Chaparral 2J

The most interesting and extremely fast model from the famous Chaparral company was the 2J which featured two fans and rubber skirts around the vehicle. Powered by an additional two-stroke engine, the fans were designed to suck air from under the vehicle and plastic skirts were there to keep the vacuum and hold the car practically sucked to the ground. That was an insane combination, but it worked, and years later, Formula One cars used the same principle which just shows how good Jim Hall`s vision was.

28. Shelby EXP 500 “Green Hornet”

Although only a working prototype, the Green Hornet featured the most innovative features for any muscle car like 390 V8 equipped with fuel injection, disc brakes on all four wheels, and independent rear suspension. With this layout, the Green Hornet was a very capable car which handled and stopped better than any other sports car on the market. Unfortunately, the cost of producing those features was too big and Ford and Shelby decided to go with more conventional technology.

29. Chevrolet Corvette ZL1

The Corvette ZL1 was kind of a secret model but still it was one of the most unusual American sports cars. The heart of the ZL1 was the fantastic and basically racing-spec fully aluminum 427 V8 with up to 550 hp in mild tune. This monster of an engine was far more powerful than anything Mopar or Ford had in production at the moment. Chevrolet produced around 200 of those engines and while most of them went to Can-Am racing teams, Chevrolet also made around 12 test Corvettes with that engine inlate 1968. The performance potential was unbelievable and Chevrolet didn’t want to offer this wild racing engine to the general public, so the ZL-1 option was never mentioned in the press or official brochures.

30. Callaway Sledgehammer C4 Corvette

Rives Callaway established Callaway Cars in 1977, long after the muscle car craze winded down and high horsepower performance machines were just a thing of past. He specialized in producing turbocharger kits to be installed mostly on European cars. His knowledge, expertise and start of the turbo era perfectly lined up and the company really took off. In order to show the real potential of twin turbo C4, Callaway produced the legendary Sledgehammer Corvette, a highly modified and heavily turbocharged 1988 Corvette which had 898 HP and could go over 250 mph!

These are the top most unusual and innovative American performance and muscle cars available today. But, car fans know Detroit is working on more of them to offer in the future. Who knows what those designers are thinking up now.
