Steps

  1. Go to the Download Fuel Economy Data page rather than the interactive ws/rest web service
  2. Download the all-model-years vehicles.csv.zip file covering 1984 through the current model year
  3. Unzip the archive locally before loading it, since files are distributed compressed
  4. Cross-reference the MPG/MPGe/kWh-per-100-mile fields against the EPA fuel economy label methodology notes on the same page
  5. Schedule a periodic re-download (e.g. annually) rather than looping the interactive menu API for a full catalog refresh
