The Green Car Vision Award is an annual award granted by the Green Car Journal. In contrast with its Green Car of the Year award, which only considers production vehicles that make the most significant environmental advancements, the Green Car Vision Award considers pre-production vehicles with more than one functional prototype in existence and that may be in the early stages of commercialization. Vehicles that are part of a demonstration fleet or other program that finds them regularly driven by people other than employees of their manufacturer may also be considered. Nominees may also include a modification of an existing vehicle model, such as a conversion to another type of power like electric drive.
