Configuration is not the same as trim. EPA records can separate engines, fuel systems, transmissions or driven wheels without identifying badges such as LX, XLE or Touring. Confirm the retail trim with the window sticker, build sheet or manufacturer VIN portal.

What the official records cover.
Each option above is tied to a unique FuelEconomy.gov vehicle ID. EPA names sometimes expose a retail badge such as LE or Woodland Edition, but many records identify only the tested mechanical configuration.

How to identify yours
Match the hardware before the badge.
- 1
Start with fuel and powertrain. Check whether the vehicle is gasoline, diesel, hybrid, plug-in hybrid, electric or fuel-cell.
- 2
Match driven wheels and engine. Use FWD, RWD, AWD or 4WD plus displacement/cylinder information from the window sticker or registration.
- 3
Confirm the exact EPA record. Select the closest option and open its FuelEconomy.gov link. Use a VIN-specific build sheet when you need the retail trim or option package.
