Rear-engine cars are fun to drive and even more fun to crash. While rear-engine packaging offers enormous advantages, putting the vehicle's heaviest component behind the rear axle gives cars a distinct tendency to spin out, sort of like an arrow weighted at the end. During World War II, Nazi officers in occupied Czechoslovakia were banned from driving the speedy rear-engined Tatras because so many had been killed behind the wheel. Chevrolet execs knew the Corvair — a lithe and lovely car with an air-cooled, flat-six in the back, a la the VW Beetle — was a handful, but they declined to spend the few dollars per car to make the swing-axle rear suspension more manageable. Ohhh, they came to regret that. Ralph Nader put the smackdown on GM in his book Unsafe at Any Speed, also noting that the Corvair's single-piece steering column could impale the driver in a front collision. Ouch! Meanwhile, the Corvair had other problems. It leaked oil like a derelict tanker. Its heating system tended to pump noxious fumes into the cabin. It was offered for a while with a gasoline-burner heater located in the front "trunk," a common but dangerously dumb accessory at the time. Even so, my family had a Corvair, white with red interior, and we loved it.
