It’s common practice for small boutique manufacturers to base their products on other carmaker’s platforms. Most times, it’s only the engines that are borrowed, but there are more than a few cases where chassis and even whole vehicles are being used as a basis for a new car. In the high-performance segment, the Corvette is the most popular choice on which other cars are based. However, the Viper platform is equally, if not more, capable and there are more than a few cars based on it.

Alfa Romeo TZ3 Zagato Stradale

Starting off with a project which celebrated 100 years (a century) of Alfa Romeo’s racing heritage, the TZ3 Zagato Stradale was unveiled at the 2010 “Concorso d’Eleganza Villa d’Este” in Italy. Zagato was responsible for styling the Stradale (Street) version of the car, of which 9 were built. The basis for this masterpiece was the fourth-generation Dodge Viper SRT-10. Of course, the bespoke coachbuilding turned the American brute into a modern-day interpretation of the iconic 1963 Alfa Romeo Giulia TZ.

For comparison, the original TZ had a 1.6-liter DOHC inline-four unit with 112 horsepower (82 kilowatts) and 160 horsepower (118 kilowatts) in race trim. Later TZ2 models had 170 horsepower. If you want the Viper-based TZ3, be prepared to pay $700,000.

Devon GTX

From Los Angeles-based industrial design house, Devon Motorworks emerged another coach-built supercar based on the fourth-generation Viper. In fact, the entire roofline is unmistakably Viper, while the rest of the body was heavily altered, featuring numerous retro design elements.

The engine was a mildly modified version of the Viper 8.4-liter V-10, and it produced 650 horsepower. As with the Alfa Romeo TZ3 reinterpretation, the V-10 is mated to a six-speed Tremec TR6060 manual gearbox. A total of 36 cars were supposed to be built, but only two are known to exist – serial number one (black) and serial number two (red).

The car also featured a fully-revised interior, where only the steering wheel and steering column remained the same as on the Viper donor car. A brand new Devon GTX would have set you back $500,000 if you go for the top-spec. In 2012, one of the cars was auctioned off for $220,000. Considering the rarity, I’d say that’s a bargain!

VLF Force One

A more recent car built on the Viper platform is the, also American, VLF Force One. It was introduced at the 2016 Detroit Auto Show and featured a stunning design, courtesy of Henrik Fisker. Force One used the underpinnings and drivetrain of the fifth-generation Viper.

This allowed the VLF Force One to hit 60 mph (97 km/h) in just 3.0 seconds, on its way to a top speed of 218 mph (351 km/h). The Tremec TR6060 was a natural choice, but there would also be an optional paddle-shift unit, available.

The VLF Force One interior was a significant upgrade from the Viper, featuring plenty of leather, smartphone connectivity, and even a champagne holder with a two-bottle capacity, located between the seats. The plan was to build 50 cars and sell them through Keating's Viper Exchange dealership, at a $286,500 sticker price. Only five cars ended up being built. If you want one now, there is one for sale at $300,000.

Bristol Fighter

History has recorded more than a few collaborations between British and American carmakers. The Bristol Fighter is one such example. For this one, we have to turn the clock back 17 years. Formula One engineer Max Boxtrom was responsible for the coupe design that featured gullwing doors. The Fighter bore some resemblance to the Jensen Interceptor and just like it, it was powered by a big frontally-mounted Chrysler engine.

From what is known about the car, it was based on earlier Viper generations and even had the earlier “smaller” 8.0-liter V-10 unit. Earlier cars produced 525 horsepower and 525 pound-feet (712 Nm). The V-10 was coupled to a six-speed manual or a four-speed automatic. The 0 to 60 mph (97 km/h) sprint was dealt with in around 4.0 seconds. The car also had a curb weight of 3,527 pounds (1,600 kg) and a drag coefficient of 0.28, which contributed to a top speed of 210 mph (338 km/h).
