In the world of auto enthusiasts, it’s quite normal to want your car to be fast. Many people dream of pulling up to a set of stop lights and leaving their competitors in a cloud of smoke and burnt rubber. Some car enthusiasts even want to turn a cool-looking car that’s not particularly quick into a fast car. However, there are some people who go a step further and want to add an extra layer of humiliation to their victories.
There is a community of people who spend their lives hunting for normal, mundane-looking cars and transforming them into racing monsters. Nobody expects a beat-up sedan to beat them in a quarter-mile race. In the world of sleepers, there are a few cars that look exceptionally uncool but come with unbelievable performance straight from the factory. These ten cars are guaranteed to deceive any unsuspecting competitor.
This list of 10 sleeper cars that are incredibly quick but not cool is based on information sourced from various automakers’ press releases.
