Dan Neil, in Time, invites the all-time 50 Worst Cars to his own rhetorical demolition derby.
1956 Renault Dauphine
The most ineffective bit of French engineering since the Maginot Line, the Renault Dauphine was originally to be named the Corvette, tres ironie. It was, in fact, a rickety, paper-thin scandal of a car that, if you stood beside it, you could actually hear rusting. Its most salient feature was its slowness, a rate of acceleration you could measure with a calendar. It took the drivers at Road and Track 32 seconds to reach 60 mph, which would put the Dauphine at a severe disadvantage in any drag race involving farm equipment. The fact that the ultra-cheap, super-sketchy Dauphine sold over 2 million copies around the world is an index of how desperately people wanted cars. Any cars.
Perfectly true. I knew someone who had one. Flooring it down a steep hill for a long time would barely get it up to 60. Riding in it was like occupying a rickety old house in a windstorm. It made an endless variety of demoralizing noises, some suggesting the imminent break-down of a vital component of the drive train, others merely alerting you to the continual flexing of the frame and body. You were always under impression that pieces were soon going to start falling off.
