Since the invention of the first horseless carriage, mankind has spent untold fortunes in the pursuit of going just a little bit faster. Why? Because there's nothing quite like a good old-fashioned bar fight over whether Car A counts as a production car, or if Car B is really faster using a special setting. The way it works around here is simple: if in the car's day, you could pick up the phone (or send a telegraph), promise a small-to-mid-sized fortune, and take delivery of your very own crazy-fast car, it counts as a production car. Ridiculously fast one-offs never meant for public consumption? Not so much.
Knowledge is power, and when that inevitable bar argument occurs, you'll do good to know your history. Here are the fastest production cars the world has ever seen, by decade. Some of them won't surprise you in the slightest, and others might be conspicuous by their absence.
