31 MPG combined is respectable for the 2021 Nissan Altima SV/SL 2.5L, especially since it’s not a hybrid. This mid-size sedan is designed for comfortable commuting and family duties, not setting fuel economy records. Buyers choosing this Altima configuration prioritize a balanced blend of space, features, and reasonable running costs, and this fuel economy fits that.

City and highway performance

The EPA estimates for the 2021 Altima SV/SL with the 2.5L engine give you a clear picture of what it can do: 27 MPG in the city and 37 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, with frequent acceleration and deceleration affecting fuel consumption. The highway figure is particularly strong, showcasing the benefits of the Altima’s continuously variable transmission (CVT) and efficient engine speeds at cruising velocity. This makes the Altima a good choice for long commutes or road trips where you drive mostly on the highway.

Annual fuel cost

The EPA estimates the annual fuel cost for this Altima configuration at $1,400. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual costs will vary based on your driving habits, the type of fuel you use, and local fuel prices. However, $1,400 provides a useful benchmark for comparing it against other vehicles and understanding its potential impact on your annual budget.

Real-world expectations

EPA figures offer a standardized estimate, but real-world fuel economy can change based on several factors. Aggressive driving, frequent hard acceleration, and carrying heavy loads will all decrease fuel economy. Consistent highway driving at moderate speeds, with gentle acceleration and anticipating traffic flow, can help you approach or even exceed the EPA estimates. Regular maintenance, including tire inflation and air filter replacement, also helps with fuel consumption.

The 2.5L engine’s smoothness and quiet operation often encourage relaxed driving, which naturally enhances fuel efficiency.

How it compares

The Altima’s fuel economy makes it competitive in the mid-size sedan segment. The Toyota Camry LE, for example, has an EPA rating of 28 MPG city and 39 MPG highway, giving it a slight edge on the highway. The Honda Accord LX achieves 30 MPG city and 38 MPG highway. The Hyundai Sonata SE is rated at 28 MPG city and 38 MPG highway. These differences are relatively small, and the Altima offers a package of features and comfort that may outweigh a marginal difference in MPG for some buyers. Someone who wants to find out more could research ALTIMA MPG across all years. Potential buyers rarely choose a mid-size sedan based solely on MPG, but they do appreciate knowing it’s more efficient than a V6-powered option.

Tips to maximize efficiency

The Nissan Altima can achieve great fuel economy; here are some tips on how to do it.

Take advantage of the Altima’s Eco mode. This setting adjusts throttle response and CVT behavior to focus on fuel efficiency. The difference can be subtle, but consistent use can improve MPG.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, leading to higher fuel consumption. Check your tire pressure regularly and inflate them to the recommended levels, which you can find on a sticker inside the driver’s side doorjamb.

Avoid aggressive acceleration and braking. The Altima’s CVT is designed to operate efficiently at consistent speeds, so accelerating smoothly and anticipating traffic stops will help you save fuel. Think ahead to avoid braking when possible, and coast to red lights.

Minimize idling. Excessive idling wastes fuel and produces unnecessary emissions. If you anticipate being stopped for more than a minute, consider turning off the engine. Modern cars like the Altima are designed to restart quickly and efficiently.
