Chevrolet Corvette ZR1Price: $111,600
Engine: 6.2-liter LS9 supercharged V8
Power: 638 horsepower; 604 lb-ft of torque
Performance: Zero to 60 mph: 3.4 seconds; top speed: 205 mph
The new 2014 Corvette Stingray might be all the rage, but it's not the king of Corvettes yet; that title goes to the mighty ZR1. It borrows technology straight from the C6.R race car that has dominated the American Le Mans racing series' GT class for years. Carbon-fiber body panels help keep the weight down to take advantage of every drop of power from the supercharged LS9 V8 engine. Although its price is about half that of a Ferrari 458 Italia or McLaren MP4-12C, the Corvette ZR1 easily keeps pace with them.
Falcon Motorsports F7Price: $195,000 to $250,000
Engine: 7.0-liter V8
Power: 620 horsepower; 585 lb-ft of torque
Performance: Zero to 60 mph: 3.3 to 3.6 seconds; top speed: 190 to 200 mph
The Falcon Motorsports F7 is a midengine, rear-wheel-drive supercar that debuted at the 2012 North American International Auto Show in Detroit. It has an aluminum and carbon-fiber chassis. Beneath its aggressively styled carbon-fiber body panels lurk a hand-built V8 engine and a 6-speed transaxle. The car weighs only 2,785 pounds, which is pretty light. Falcon Motorsports, a startup based in Holly, Mich., is taking orders for the initial production run of 10 vehicles. The goal is to eventually ramp up to 25 cars a year.
Ford Mustang Shelby GT500Price: $54,200
Engine: 5.8-liter supercharged V8
Power: 662 horsepower; 631 lb-ft of torque
Performance: Zero to 60 mph: 3.5 seconds; top speed: 202 mph
The Ford Shelby Mustang GT500 is easily the bargain of this bunch. Some might argue that with Mustang underpinnings and an interior that is coarse and unrefined, it doesn't achieve true supercar status. But the performance figures speak for themselves. Granted, the suspension is crude when compared with a car such as the Corvette ZR1, but it can keep up with some of the best sports cars in the world, thanks to its excellent weight distribution and precise steering.
Hennessey Venom GTPrice: $600,000 to $1 million
Engine: 7.0-liter LS9 twin-turbocharged V8
Power: 1,244 horsepower; 852 lb-ft of torque
Performance: Zero to 60 mph: 2.7 seconds; top speed: 272 to 278 mph
The Hennessey Venom GT is one of the most extreme American exotic cars, though it does possess some British traits. In simple terms, the Venom GT is a tuned General Motors LS9 V8 engine stuffed into a heavily modified Lotus Elise chassis. A version with 750 horsepower starts at $600,000; if you want the full 1,244 horses, the price of entry is $1 million. It weighs only 2,743 pounds and has one of the best power-to-weight ratios of any production car ever. Hennessey Performance Tuning is based in Houston.
Mosler MT900SPrice: $164,000 (estimated)
Engine: 7.0-liter LS7 V8
Power: 530 horsepower; 515 lb-ft of torque
Performance: Zero to 60 mph: 3.5 seconds; top speed: 179 mph (estimated)
Mosler Automotive, based in Riviera Beach, Fla., has been building race cars and road cars since 1993. The MT900s is its current road warrior, boasting an LS7 V8 engine sourced from GM. The car's chassis and body panels are made of carbon fiber, but also have Kevlar the same stuff used in bulletproof vests woven in for added strength. "Star Wars" creator and director George Lucas reportedly was the first person to take delivery of an MT900s.
Rossion Automotive Q1Price: $100,595
Engine: 3.0-liter twin-turbocharged Ford Duratec V6
Power: 450 horsepower; 390 lb-ft of torque
Performance: Zero to 60 mph: 3.1 seconds; top speed: 189 mph
The Rossion Q1 has the smallest engine by far of this remarkable group, but the 2,480-pound midengine devil gives up nothing in performance, thanks to its power-to-weight ratio and balance. The Q1 evolved from the Noble M12, an award-winning British supercar that Pompano Beach, Fla.-based Rossion Automotive bought the rights to produce in 2007. The suspension was reworked and the whole package was refined with attractive bodywork and a more luxurious interior. The Q1 is built by High Tech Automotive in Port Elizabeth, South Africa. With British roots and ties to South Africa, it perfectly represents the American mosaic.

Power: 640 horsepower; 600 lb-ft of torque
Performance: Zero to 60 mph: less than 3.5 seconds (estimated); top speed: 206 mph (estimated)
The Viper is back from extinction and better than ever. But it's no longer a Dodge. Now this beast is sold under a new SRT brand, which was formed after Fiat reorganized Chrysler. The good news is there's still a monster V10 engine under the long hood to provide plenty of venom. The big difference is that SRT has tamed the unruly reptile by giving it a better ride and an upscale interior. There's even a new GTS version with added amenities, so buyers can pick their poison.

Tri-Cities, Wash.-based SSC was founded in 1999 by car enthusiast and entrepreneur Jarod Shelby, no relation to auto industry legend Carroll Shelby. The Ultimate Aero XT showcases a new V8 engine with a billet aluminum block, a 7-speed paddle-shift transmission and other systems that will be used on SSC's next mind bender, the Tuatara.
