In Mitsubishi’s current U.S. lineup, the Mirage is the most fuel-efficient gasoline-powered model, delivering the best gas mileage among Mitsubishi’s traditional engines. Expect highway figures in the high-30s mpg and a mid-30s combined average. If you’re considering electrified options, the Outlander PHEV offers exceptionally high MPGe when charged, but its gasoline-only fuel economy is lower than the Mirage’s.
Gasoline-only models with the best mileage
This section covers Mitsubishi’s pure gasoline-powered vehicles. The Mirage family remains the standout for efficiency, with larger models posting noticeably lower fuel economy due to their size and weight.
- Mitsubishi Mirage (CVT) — EPA estimates show around 39 mpg on the highway, about 33–35 mpg in city driving, with a combined figure in the mid- to high-30s (roughly 36–37 mpg).
- Mitsubishi Mirage G4 (CVT) — Similar efficiency to the hatchback Mirage, typically around 39 mpg highway, ~33 mpg city, and roughly 36 mpg combined.
- Mitsubishi Outlander (gasoline-only, 2.5L) — Significantly less efficient; commonly around the mid-20s mpg combined (roughly 23–25 city, 30–31 highway, depending on year and drivetrain).
Bottom line: for pure gasoline efficiency, the Mirage lineup leads, while the Outlander and other larger models consume more fuel.
Electrified options and overall efficiency
For buyers interested in electrified powertrains, Mitsubishi’s Outlander PHEV provides very high energy efficiency when charged, though its gasoline-only performance is not as strong as the Mirage. The following figures illustrate the trade-offs between electric-assisted efficiency and gasoline use.
Outlander PHEV
In EPA ratings for recent model years, the Outlander PHEV achieves about 74 MPGe combined (electric plus gasoline). When operating on gasoline alone, it generally returns around 25 mpg. Its electric range is typically in the 18–25 mile range depending on year and battery conditions.
- Outlander PHEV — 74 MPGe combined; gasoline-only mpg around 25; electric range ~18–25 miles.
Keep in mind that MPGe and gas-only mpg vary by year, trim, and how often the vehicle is charged. Regular charging can dramatically reduce gasoline usage, while running without charging emphasizes gasoline economy.
Summary
The Mirage is Mitsubishi’s most fuel-efficient gasoline-powered option, delivering the best gas mileage among their current lineup. Electrified options like the Outlander PHEV offer standout MPGe when charged, but their gasoline-only efficiency trails the Mirage. For pure gasoline economy, the Mirage remains the clear choice; for overall efficiency with charging, the Outlander PHEV is worth considering.
