History of the Shelby Series 1
A modern Cobra
The Series 1 was intended as a modern interpretation of the Shelby AC Cobra. Although it was first presented as an entirely in-house project, much of the production run was overseen by General Motors, and many components came from its parts bin, including the engine. The car had a welded aluminium chassis of extruded and formed 6061 alloy, post-heat-treated for strength, with aluminium honeycomb panels bonded into the floor and rocker panels. The body panels were a carbon fibre and fibreglass laminate. The engine sat completely behind the front axle, giving a 50/50 weight distribution, and drove through a torque tube to a six-speed ZF transaxle.
Problems and production
Before production began, significant costs went into testing and certification for the 1999 Federal Motor Vehicle Safety Standards. In early 2000 Shelby announced a retroactive price increase but had to back down within weeks. The soft top did not attach properly and had to be re-engineered after the first sixty-odd cars were built, and thirty cars were delivered without tops, with technicians sent to buyers’ homes to fit them. A run of 500 cars had been announced, but 249 were built, all as 1999 models.
After the original run
During production the Venture Corporation bought Shelby American, including the rights to the Series 1 but not to the Continuation Series Cobras. After Venture went bankrupt in 2004, Carroll Shelby’s new company, Shelby Automobiles, bought the Series 1 assets and enough components to build several more cars. Because the safety certificate had expired and re-certification was too expensive, later cars were completed as component cars without engine or transmission, with seven-digit VINs and CSX5000 serial numbers.
