Fuel efficiency
The Nissan Altima is a fuel-efficient car, with a standard 2.5-liter Direct Injection Gasoline (DIG) engine delivering up to 32 combined mpg. The introductory-level models are even more fuel-efficient as they weigh less, allowing them to go further on less gas.
The 2024 Nissan Altima has an EPA-estimated fuel efficiency of 27 mpg in the city and 39 mpg on the highway in select models. The 2025 model has an EPA-estimated fuel efficiency of 28 mpg in the city and 39 mpg on the highway. The front-wheel-drive version of the Nissan Altima achieves an EPA-estimated 28 mpg in the city and 39 mpg on the highway with the 2.5L engine. With all-wheel drive, the EPA estimates drop to 26 mpg in the city and 36 mpg on the highway.
The Nissan Altima's impressive fuel efficiency is due in part to its engine and drivetrain, as well as its trim. The standard engine can be paired with either front- or all-wheel drive, but only in certain trim levels. The available Intelligent Cruise Control also helps improve fuel efficiency by keeping a steady pace on the road. Additionally, the Nissan Altima has standard tire-specific Tire Pressure Monitoring that alerts the driver when a tire is underinflated, as underinflated tires cause the car to use more gas.
To further improve the fuel efficiency of the Nissan Altima, it is recommended to remove unnecessary items from the car to make it lighter. It is also important to maintain proper tire pressure, as underinflated tires create extra friction with the road, reducing efficiency. Choosing routes that avoid stop-and-go traffic can also help improve fuel efficiency.
