The 2023 Nissan Altima with its 2.5L 4-cylinder engine gets an estimated 31 MPG combined. While not the highest efficiency, it balances practicality, affordability, and some driving enjoyment. Altima buyers typically want a comfortable, reliable mid-size sedan that’s easy on gas, and this Altima fits that description.

City and highway performance

The EPA estimates the 2023 Altima 2.5L will achieve 27 MPG in the city and 38 MPG on the highway. The city figure is respectable for a car of this size. The Altima’s relatively light weight (around 3,300 lbs depending on configuration) and the efficiency-focused programming of its continuously variable transmission (CVT) help fuel economy.. The 38 MPG highway rating is where the Altima is strong, making it a good choice for commuters or those who take long road trips. The CVT helps the engine operate at its most efficient RPM range at cruising speed. However, hard acceleration will decrease these numbers because the small engine has to work harder at speed if you punch the gas.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2023 Nissan Altima 2.5L at $1,400. This is based on driving 15,000 miles per year, using an average national fuel price. Your actual fuel costs will vary depending on your driving, your local fuel prices, and the mix of city and highway driving you do, but $1,400 is a useful benchmark for comparing the Altima’s running costs to other vehicles. This number helps the pragmatist recognize how the Altima fits into their annual budget.

Real-world expectations

While the EPA figures offer a standard comparison, real-world fuel economy often varies. Expect to see figures close to the EPA estimates with the Altima 2.5L if you drive conservatively. In mixed driving, expect a number in the high-20s to low-30s. If you push the Altima harder, that number will drop, especially in stop-and-go traffic or during repeated acceleration. The weather plays a role; colder temperatures often reduce fuel economy due to increased engine friction and auxiliary systems like the heater. Tire pressure is also a factor. Owners who want good fuel efficiency and drive sensibly will find the Altima’s real-world performance is close to its EPA ratings.

How it compares

The mid-size sedan segment is very competitive, and fuel economy is important. The Toyota Camry, another popular choice, gets an EPA-estimated 32 MPG combined with its base 2.5L engine. Some Camry trims achieve as high as 39 MPG combined. The Honda Accord has similar numbers to the Altima, with an EPA-rated 32 MPG combined for its 1.5L turbocharged engine. The Hyundai Sonata is another option, with its base 2.5L engine delivering around 32 MPG combined. The Sonata Hybrid gets much higher numbers for buyers wanting maximum efficiency. The Altima’s fuel economy is competitive, placing it in the middle. The choice often comes down to styling, features, and driving preferences. Compare ALTIMA MPG across all years here.

Tips to maximize efficiency

The Nissan Altima’s CVT is programmed for fuel efficiency if you drive accordingly. Avoid fast acceleration and maintain a steady pace. The CVT works best when you let it transition between its simulated gear ratios. Hard driving forces the engine to work harder, reducing the transmission’s efficiency.

Make sure your tires are at the recommended pressure, found on a sticker inside the driver’s side door. Underinflated tires increase rolling resistance, making the engine burn more fuel. Check your tire pressure regularly, especially during seasonal temperature changes.

Reduce extra weight in the car. The more weight the Altima carries, the harder the engine works, and the more fuel it uses. Remove extra items from the trunk and passenger area to improve fuel economy.

Watch your speed on the highway. Aerodynamic drag increases quickly as speed increases, so driving at 75 mph instead of 65 mph can significantly reduce fuel economy. Maintain a consistent speed and avoid lane changes to improve your MPG.

Plan your routes to avoid stop-and-go traffic. Idling uses fuel without covering distance. Minimizing time in traffic can improve your fuel economy. Consider using navigation apps with real-time traffic updates to find the best route.
