US sports car designer Carroll Shelby dies aged 89
His company, Carroll Shelby International, said Mr Shelby died at a hospital in Dallas, Texas.
Mr Shelby, who had a long and varied career, had a heart transplant in 1990 and a kidney transplant in 1996.
The former chicken farmer first made his name as a successful racing car driver, winning dozens of races in the 1950s.
According to BBC, among them was the gruelling 24-hour Le Mans race in France which he won with teammate Ray Salvadori in 1959.
But after being diagnosed with a serious heart condition he turned his attention to designing high-powered "muscle cars".
In 1962 Mr Shelby test-drove the AC 260 roadster, the car made with a Ford engine that would become the Shelby Cobra.
The Cobra, which also used a British sports car chassis, was the fastest production model ever made when it was displayed at the New York Auto Show in 1962.
