Fuel types in the lineup
Infiniti models in this dataset run on gasoline and hybrid. Choosing a hybrid or electric version cuts the fuel line of the budget the most, especially in city driving, while a conventional gasoline model usually costs less to buy in the first place. Use the comparison tool to set the trade-off against a rival in the same class.
Coverage and method
This Infiniti section covers 7 models over 30 model-years, drawn from the U.S. EPA's fuel economy files and NHTSA crash-test data. Every figure is an official estimate, so use it to compare vehicles and spot the outliers rather than as a promise of what you will get at the pump. Where a model changed engines, transmissions or body styles between years, the year-by-year pages show the difference.
Pick a model for its year-by-year fuel economy and specs, or open the comparison tool to line any two up side by side. ← All makes
