Between 1958 and 1962, the trained aeronautical engineer Bob Carnes built 30 to 40 sports cars in Lakewood (Colorado), which won some laurels on the racetrack and can be considered the forerunners of the Cobra, as they combined American drive technologies with a European-influenced chassis. Equipped with plastic bodies throughout, the sporty vehicles for the racetrack and road are reminiscent of the cars by Devin and Kellison, which had similar concepts. This report portrays Carne's most successful sports car, the XP-5, and shows it in current and historical pictures.
