What Is a Sleeper Car?
A sleeper car is a master of understatement in the automotive world. It's a car that offers considerable performance yet is bereft of indecent bodywork, garish paint, oversized aerodynamic elements, or anything else that might invite unwanted attention. To call a car a sleeper is to pay it a big compliment. Usually, anyway.
Not everyone wants to drive a sleeper car, of course, because sometimes it's fun to show off. Likewise, it would be senseless for some cars to play down their capabilities because outward personality is such a huge part of their appeal. A Chevrolet Corvette could never be a sleeper car. Nor could a Tesla Model S, a Subaru WRX STI, or any Dodge, especially one with Hellcat in its name.
But for drivers who favor stealth over showboating, there are plenty of cars that pack in more performance than initially meets the eye.
