Under the hood, the 2026 Nissan Altima features a 2.5 liter DOHC 4-cylinder engine matched with Nissan’s Xtronic continuously variable transmission. Front-wheel-drive models achieve an EPA-estimated 27 mpg in the city and 39 mpg on the highway, placing the Altima among the more fuel-efficient options in its class.

For drivers who prefer added traction, models equipped with intelligent all-wheel drive offer slightly adjusted mileage ratings. These versions earn EPA-estimated ratings of 26 mpg city and 36 mpg highway, allowing for confident driving in varying conditions while still maintaining competitive efficiency.

The 2026 Nissan Altima is designed to make the most of its fuel efficiency with a tank size that supports extended driving. Front-wheel-drive models are equipped with a 16.2 gallon fuel tank, while all-wheel-drive versions feature a 15.4 gallon tank due to packaging differences in the drivetrain.

Combined with the Altima’s strong highway mileage, this fuel capacity allows drivers to travel longer distances between fill-ups. Whether commuting around Shiloh, IL or heading out on longer trips, the Altima helps reduce the need for frequent refueling stops.
