The engine is the crown jewel of any automobile and can make or break a car in the eyes of an automotive enthusiast. No matter how sweet a car's handling or how neutral its balance, a limp-wristed engine can completely kill the machine's ability to put a smile on your face. Conversely, nothing screams buzzkill quite like a glorious engine cooped up in a dowdy package. Such is the case with the ten vehicles that made their way on our Top Ten Cars That Don't Deserve Their Engines list. Unfortunately, the powerplants under the hoods of these ten cars are forever destined to mediocrity. Some may consider these cars sleepers due to their often unassuming wrappers, but we maintain these engines would rather live a life free of their humble trappings; free to ingest the atmosphere with reckless abandon and exhale their burnt offerings to the gods of a good time.
