This is not the kinda hit Robin Thicke is looking for -- the singer slammed his high-end sports car into another car on Sunset Blvd last night.
According to law enforcement ... Robin told cops another car cut him off as he was leaving Chateau Marmont ... forcing him to swerve his black convertible Porsche into a parked car.
Robin's ride sustained serious damage to the front and back end ... but we're told no one was injured in the wreck. The parked car, a Volkswagen, was also towed from the scene.
We're told police do not believe alcohol or drugs were involved, and there is no criminal investigation. An officer even gave Robin a ride to his nearby home.
