What you can do here

  1. Open a vehicle class to see every model of that size ranked by combined MPG, with annual fuel cost and CO2 beside it.
  2. Use the filter and sort controls on any table to narrow it to a make, a powertrain or a model year.
  3. Open a model to see all of its rated versions, a dot chart of its class, and its rating by model year.
  4. Type your own miles per year and fuel prices in the box on a page and every annual cost on it recalculates.
  5. Read a head-to-head page to see two models of the same class side by side.

Annual fuel cost in the file is based on 15,000 miles a year, 55% city and 45% highway driving, and the fuel prices that fueleconomy.gov published at the time of the release (the same prices for every model year).
