Where these figures come from
- Vehicle details are decoded from VIN data published by NHTSA's vPIC database.
- Fuel economy comes from the EPA's published fuel economy dataset.
- Recall campaigns come from NHTSA. A campaign covers a VIN range within a model year, so a listing here is never a statement about a specific vehicle.
- Service specs are compiled per trim. Anything marked Estimated was derived from the engine rather than read from a published specification, and your owner's manual or door placard outranks it.
