In order to help customers to know if a vehicle is efficient, or a least less bad for the environment, AutoWest and Power Auto Group (members of AutoNation) are introducing a new system in order to label cars called the E-Vehicles program. This system will mark cars with a green, leaf-shaped E-Vehicle logo (the additional sticker) if that produce at least 28 miles-per-gallon or delivers 10 percent better fuel efficiency than the average for their vehicle class.
A similar system, called F-Vehicles, will label with a yellow, leaf-shaped logo cars and trucks that make use of flex fuel or ethanol-based technology. Both systems were developed by AutoNation together with Edmunds.com.
Among the most in-demand models are the Toyota Prius, the Honda Civic Hybrid, the midsize Chevy Malibu and the Mercedes-Benz Diesel. Best-in-class E-Vehicles include the Toyota Tacoma pick-up, the Ford Escape Hybrid SUV and the Dodge Grand Caravan minivan[Source: AutoNation]
