American Specialty Cars

The American company ASC (American Specialty Cars) showed its creative expertise at the 2006 North American International Auto Show by unveiling a supercar made even more super by the addition of a mostly carbon-fiber body.

A snake with an all-new skin, the ASC Viper Diamondback is super-light and super-fast. It’s fitting that ASC, which helped the Chrysler Group bring the new Dodge Viper SRT10 coupe to life, would, with the aid of McLaren Performance Technologies, show how the Viper coupe might be taken to an all-new level of extreme. The 615 bhp Viper Diamondback features a carbon fiber roof, deck lid, rockers, fascia inserts, body trim and a massive OmniCarbon hood that shows off ten unique trumpeted air intakes, with individual port throttles, peeking through – a McLaren Performance Technologies feature reminiscent of McLaren Can-Am engines of the past.

The hood also shows off compression-molded carbon fiber. It’s displayed beautifully, with a broad, clearcoated racing stripe down the Artic White-painted expanse, subtly outlined by “Viper Blue” and “McLaren Red” pinstripes. In all, ASC removed about 85 lbs. of weight from the vehicle – including cutting the weight of the hood by nearly half versus the production model. Taken together with the powertrain modifications by McLaren Performance Technologies, the power-to-weight ratio was increased, resulting in an estimated increase in 0-60 mph time of 3.5 seconds.

American Specialty Cars (commonly known as ASC or American Sunroof Company) was an automobile supplier of highly engineered and designed roof systems, body systems and other specialty-vehicle systems for the world’s automakers. The company was headquartered in Warren, Michigan, in the United States and was one of several coach convertible builders. ASC sold assets to its Creative Services division in late 2016 to Roush Industries. In late June 2017, ASC effectively ceased operations, laying off all staff and had tooling and production equipment removed from the manufacturing plant in Lexington, Kentucky.
