, under Mitchell's direction. The designs for both the 1963 Corvette and the 1963 Riviera were accepted by their respective divisions on Christmas Eve 1961, in what Mitchell referred to as perhaps the greatest moment of his life.

Mitchell's fondness for split rear windows as featured on the 1957 Buick and on the 1963 Corvette Stingray coupe was not shared by some of his fellow stylists or the buying public and both cars dropped the feature after a measure of public resistance. The split rear window would be eliminated (and re-worked into one pane of curved glass) for the 1964 Corvette coupe. The 1963-1967 Stingray (in both coupe and roadster editions), with its slightly bulged front and rear quarter-panels, would be one of the first General Motors cars to feature what came to be known as "Coke bottle" styling, creating an aggressive and muscular look.
Mitchell also influenced the dramatic styling of the second generation 1965 rear-engine
Corvair, which, like other GM models introduced for that year, used curved side-window glass to enhance its "Coke Bottle" profile.
1970s

During the 1973–74 energy crisis, which brought on a greater demand for smaller cars in place of the larger cars that had been GM's bread and butter profit machine for decades, Mitchell oversaw the styling and design efforts of GM's downsized full-sized and intermediate-sized cars which were introduced in the late 1970s, some of the last designs that he would lead—and all largely based on themes first developed in his 1976 Cadillac Seville. However, when it came to compact and subcompact cars, Mitchell, who often struggled with alcoholism, reflected that "Small cars are like vodka. Sure people will try them out but they won't stay with them."
Mitchell stepped down as chief stylist in July 1977 following his 65th birthday. The last car he designed at GM was the 1977
Pontiac Phantom concept, which now resides at the
Sloan Museum. He was also instrumental in the design of what would become the 1980–1985 Cadillac Seville. On August 1, 1977,
Irv Rybicki succeeded Mitchell as Vice President of General Motors Design.
1980s
Following his retirement from General Motors, Mitchell ran William L. Mitchell Design, a private design-consulting firm, from 1977 to 1984. He was a vocal critic of the new
fourth-generation Corvette's styling, which he referred to as "bland." Bill Mitchell died at the age of 76 from heart failure at William Beaumont Hospital in
