Another data update - you can now find the fuel economy and other info for all 2012 model-year automobiles sold in the US in our public data repository.
This data release took unusually long to process because we decided to improve the way we handle dual-fuel and alternate fuel vehicles in light of their increasing popularity. We now store all EPA-reported fuel efficiencies for every vehicle. Using the Automobile or Automobile Trip impact models on Cm1 you can specify a particular fuel with the ‘automobile fuel’ characteristic.
