4. Chevrolet Corvair
The Chevrolet Corvair, produced from 1960 to 1969, featured a rear-engine design that appealed to driving enthusiasts. However, its swing-axle rear suspension led to handling issues, including oversteer and potential rollovers during sharp turns. In 1965, consumer advocate Ralph Nader highlighted these safety concerns in his book “Unsafe at Any Speed,” leading to public scrutiny and a decline in sales. Despite its challenges, the Corvair remains a notable example of automotive innovation and controversy. (en.wikipedia.org)
