What is the gas mileage on a 2016 Subaru Legacy 2.5 I Premium?

The 2016 Legacy 2.5i Premium with its standard CVT and all-wheel drive delivers about 29 mpg combined, with roughly 26 mpg in the city and 36 mpg on the highway.

Overview of the official fuel-economy figures

These numbers come from the EPA and reflect the car’s 2.5-liter flat-4 engine paired with Subaru’s CVT and all-wheel-drive system. They serve as a baseline for comparing efficiency across vehicles and trims in the Subaru lineup.

Because the Legacy is built with all-wheel drive as standard, its efficiency ratings are typically lower in the city than some front-wheel-drive sedans, while highway figures benefit from steady cruising and aerodynamic efficiency.

EPA fuel-economy estimates

Below are the official EPA estimates for the 2016 Legacy 2.5i Premium. They illustrate the breakdown between city, highway, and combined fuel economy.

• City: 26 mpg


• Highway: 36 mpg


• Combined: 29 mpg

These values assume standard equipment (CVT transmission and all-wheel drive) and typical driving conditions used by the EPA.

Real-world factors that influence mpg

Actual fuel economy can vary based on driving style, terrain, climate control usage, tire type, and load. Aggressive acceleration, frequent stops, or carrying heavy cargo can reduce mpg, while steady highway cruising and mild weather can approach or exceed the EPA highway figure.

Context within the model lineup

The 2.5i Premium shares its engine and drivetrain with other 2.5i trims from the 2016 Legacy lineup. While the core performance is similar, minor differences in tires or trim-specific equipment can yield small variations in real-world efficiency.

Summary

The 2016 Subaru Legacy 2.5i Premium is EPA-rated at 26 mpg city, 36 mpg highway, and 29 mpg combined, reflecting its AWD and CVT setup. Real-world results will vary, but these ratings provide a solid baseline for budgeting fuel costs and planning trips.
