Sleeper

I term used by serious car guys to describe a vehicle that is plain and boring looking but is really fast as shit. Basically it’s a car designed to look like something your grandmother would drive but it has a big bad ass 5.0L V8 engine under the hood.

That 5.0 Hyundai Genesis R-Spec 4-door sedan is a straight up sleeper. It has 440 hp and my grandma loves driving it because it’s easy to drive.
