The Acura TSX V6 remains unnoticed by many drivers who evaluate sport sedans. Though the Acura TSX V6 lacks the eye-catching style of its German rivals it boasts substantial performance with its 280-horsepower engine. The car's discreet appearance along with its powerful performance make dedicated car fans call this vehicle a sleeper car. Some say its mild design prevents it from being a genuine sleeper vehicle. People argue whether the TSX V6's mix of comfort and power creates sufficient stoplight surprises or remains just an enhanced regular sedan.
