Fiat cars: MPG and fuel economy by model
The EPA has rated 84 vehicles from Fiat across 10 distinct models since 2012. The list below covers every Fiat model with its combined MPG and estimated annual fuel cost, organised by model year so you can see how the lineup has evolved.
Below you will find every Fiat model in the EPA dataset, split into a recent table for the last five model years and a longer table for the rest. Click any model and year to see the full breakdown, including city and highway MPG, tailpipe CO₂ emissions, and the engine and drivetrain specification.
Fiat fuel economy snapshot
Across every Fiat the EPA has ever rated, the most efficient is the 2026 Fiat 500e at 116 combined MPG. That figure includes electric vehicles, which use MPGe rather than a true gallon of fuel.
For the 2026 model year, Fiat's lineup averages 113 combined MPG across 10 models. The lineup is currently 25% electric, 75% gasoline.
The bar chart below ranks the most efficient Fiat models for the 2026 model year. Use it as a quick way to spot the leader in the lineup, then click through for the full breakdown of city and highway MPG, annual fuel cost, and the engine and drivetrain.

Recent Fiat models
Recent Fiat models from the 2022 model year onward, sorted by year and model. Trims appear separately when the EPA rates them as distinct vehicles (for example, when an all-wheel-drive variant has its own MPG figures).

Older Fiat models
Older Fiat models, going back to 2012. The EPA's testing methodology has changed several times over the decades, so direct comparison between a 1980s rating and a modern one is not always meaningful. Use these figures to track the trend within a model rather than across eras.
