“One label design prominently features a letter grade to communicate the vehicle’s overall fuel economy and greenhouse gas emissions performance. The new design will also provide consumers with an estimate of the expected fuel cost savings over five years compared to an average gasoline-powered vehicle of the same model year.

“The second proposed label retains the current label’s focus on miles per gallon (MPG) and annual fuel costs, while updating the overall design and adding the required new comparison information on fuel economy and emissions.

“Both proposed label designs expand on the content of the current label by including new information on fuel consumption, tailpipe carbon dioxide (CO2) emissions and smog-related emissions. The new labels would provide information on a new web-based interactive tool that can also be accessed by smart phone. This tool would allow consumers to personalize the information about a vehicle’s performance.”
