The first Shelby Cobra was prototype CSX2000, an AC Ace-derived roadster developed through a partnership between AC Cars, Ford, and Shelby American. AC worked on the chassis and body in England; Shelby’s team installed a Ford 260-cubic-inch V8 and four-speed transmission in California. CSX2000 made its first public appearance at the New York Auto Show in April 1962.
Its story is not of a finished car emerging from a single workshop, but of a prototype built in stages across the Atlantic and used to introduce the Cobra to the public.

How the Cobra project began
In 1961, as AC lost its Bristol engine supply, Carroll Shelby proposed that the company continue building its roadster chassis for a sports car powered by an American V8. AC owner Charles Hurlock responded positively if Shelby could find a suitable engine. Shelby then pitched the idea to Ford executive Lee Iacocca; Ford agreed to supply engines and support.
The roles were distinct: AC supplied and modified the Ace-derived chassis and body, Ford supplied the power, and Shelby American developed and marketed the car. The FIA homologation form later named Shelby American, Inc. as the manufacturer and “Cobra” as the model, while documenting Carroll Shelby’s certification on September 11, 1962.
#1 Best Overall
- Prototype Cobra's Journey: CSX2000, the sole prototype, remained with the Shelby family until 2016, fetching $13.75 million at auction
- CSX2001's First Owners: Initially owned by American racer Ed Hugus, it later passed to Frenchman Jean-Marie Vincent, who raced it in Europe
- CSX2002's Racing Debut: Nearly won its first race at Riverside, but a broken rear hub sidelined it. Dave MacDonald secured the first Cobra win in Tucson
- Current Ownership: All three cars are now part of prestigious U.S. collections. CSX2000 and CSX2002 belong to the Larry Miller Collection, while CSX2001 is owned by Bruce Meyer
- Book's Visual Appeal: The book features a rich mix of period and contemporary images, many of which have not been seen before
What made CSX2000 more than an engine swap
CSX2000 was based on the AC Ace, but it was not simply an unchanged Ace fitted with a larger engine. The Shelby American Collection records a limited-slip Salisbury rear end, inboard rear disc brakes, reinforced suspension, thicker-wall main chassis tubes, and what AC described as a “general beefing-up through-out.”
The documented build happened in stages:
- AC worked on and tested the prototype in England. The Shelby American Collection says it was tested at the Mira track with a Ford Fairlane 221-cubic-inch V8.
- After the prototype was finished in late February 1962, without its final engine and transmission, it was air-freighted to Los Angeles.
- At Dean Moon’s shop in Santa Fe Springs, California, Shelby’s team installed a four-speed transmission and one of the first Ford 260-cubic-inch V8s.
Sources describe milestones differently, so there is no need to reduce the multi-stage work to one supposedly definitive completion date.
The name and the first public appearance
Shelby later recalled how he came up with the name. In the account reproduced by the Shelby Racing timeline, he said: “I woke up and jotted the name down on a pad which I kept by my bedside-a sort of ideas pad- and went back to sleep. Next morning when I looked at the name ‘Cobra,’ I knew it was right.”
CSX2000’s first public appearance was at the New York Auto Show in April 1962, in the Ford display. The Shelby American Collection says the car was painted pearlescent yellow because Shelby was advised it would look best under fluorescent lights.

How one prototype introduced the Cobra
CSX2000 also served as a factory demonstrator. The Shelby American Collection says it was repainted during promotional activity, helping create the impression that production was more active. The source does not establish a repaint count or quantify the effect on orders.
The prototype’s importance lies in the way the project joined AC’s chassis and body work with Ford power and Shelby American’s development and marketing. That cross-company, cross-Atlantic process—not the image of a lone builder creating a finished car in one place—is the documented story behind the first Cobra.
