In order to demonstrate that a light duty vehicle is an “on-road advanced technology vehicle”, an automobile manufacturer must provide the following:

- (a) **Emissions certification.** An automobile manufacturer must certify in writing that the vehicle meets, or will meet, the emissions requirements specified in the definition of “on-road advanced technology vehicle”; and
- (b) **Demonstration of fuel economy performance.** An automobile manufacturer must demonstrate that the vehicle has a combined average fuel economy of at least 125 percent of the average combined fuel economy for vehicles with substantially similar attributes for model year 2005.
  - (1) A combined average fuel economy calculation required under this paragraph for a vehicle that is a dual fueled automobile for the purpose of CAFE is calculated as if the vehicle were not a dual fueled automobile.
  - (2) The average combined fuel economy for vehicles with substantially similar attributes is a harmonic production weighted average of the combined average fuel economy of all vehicles with substantially similar attributes in model year 2005, as published by DOE.
  - (3) In the case of an electric drive vehicle with the ability to recharge from an off-board source, an automobile manufacturer must provide DOE with a test procedure and sufficient data to demonstrate that the vehicle meets or exceeds the applicable average combined fuel economy of vehicles with substantially similar attributes.
