Was Ralph Nader's Chevrolet Corvair really unsafe at any speed?
The book ‘Unsafe at Any Speed’ by Ralph Nader is synonymous with the rear-engined Chevrolet Corvair. Just one of its eight chapters was themed around the unusual American family car, but it was enough to condemn it in the eye of the public.

It was an alternative take to the typical front-engined family car that boasted improved packaging as a result.

The bigger issue wasn’t the car’s design itself, but the lack of communication in regards to maintenance.Chevrolet’s Corvair required substantially different tyre pressures for the front and rear sets, meaning that typical car buyers might make the mistake of equally topping up each tyre. This sort of advice might not have been made clear at the dealership, nor the fact that there was an option for stiffer suspension should you wish to drive your car with added gusto.Ralph Nader’s ‘Unsafe at Any Speed’ is an important book in automotive history that was crucial to the passing of seat belt laws in many American states.
