29 MPG combined is respectable for the 2021 Nissan Altima AWD 2.5L. This figure highlights the Altima’s appeal: affordable practicality for those who need year-round traction without sacrificing a comfortable ride or spending too much on gas. This isn’t a sports sedan; it’s a sensible choice for families, commuters, and anyone who values reliability and ease of use.

City and highway performance

The EPA estimates for the 2021 Altima AWD 2.5L are 26 MPG in the city and 35 MPG on the highway. The city figure reflects the stop-and-go driving conditions that can tax any engine, but the Altima’s relatively modest 2.5L four-cylinder and smooth CVT help it maintain a decent level of efficiency. The highway MPG demonstrates that the Altima is a comfortable and efficient long-distance cruiser. This split suits the needs of the Altima’s typical owner, someone who might face congested commutes during the week but appreciates the ability to take longer trips on weekends without excessive fuel costs. The continuously variable transmission (CVT) plays a large role here, optimizing engine speed for efficiency even if it doesn’t deliver the most engaging driving experience.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Nissan Altima AWD 2.5L at $1,500. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices. It’s a helpful benchmark for comparing the Altima’s running costs against other vehicles. Remember that your actual fuel costs will vary depending on your driving habits, location, and prevailing fuel prices. If you drive more aggressively or spend most of your time in heavy traffic, expect to spend more. If you drive mostly on the highway and practice fuel-efficient driving techniques, you could potentially spend less than $1,500 per year.

Real-world expectations

EPA estimates are a useful starting point, but understanding the true ALTIMA MPG requires considering real-world experiences. Some drivers report achieving figures close to the EPA estimates. Others find that their mileage falls slightly short, particularly in colder climates or with frequent short trips, which don’t allow the engine to reach its optimal operating temperature. Consistent maintenance, including regular oil changes and properly inflated tires, can help maintain fuel efficiency. Aggressive acceleration and hard braking will always negatively impact MPG, The EPA sticker confirms this.

How it compares

Compared to other mid-size sedans with available all-wheel drive, the 2021 Nissan Altima AWD 2.5L is competitive but not class-leading. The Subaru Legacy, with its standard all-wheel drive, achieves a similar 27 MPG combined in most trims. The Toyota Camry AWD, another popular choice, gets around 28 MPG combined. The Mazda 3 sedan, when equipped with all-wheel drive and its base 2.5L engine, delivers fuel economy numbers nearly identical to the Altima. The slightly lower fuel economy compared to some front-wheel drive competitors is a trade-off that Altima AWD buyers willingly accept for the added security and control of all-wheel drive, especially in regions with inclement weather. These buyers prioritize safety and all-weather capability over outright fuel efficiency, but still want a vehicle that’s reasonably economical to run. For all Nissan fuel economy data, click here.

Tips to maximize efficiency

Regularly check your tire pressure and keep your tires inflated to the recommended PSI. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. A simple tire pressure gauge can make a noticeable difference.

Avoid aggressive driving habits such as rapid acceleration and hard braking. Gentle acceleration and anticipation of traffic flow can significantly improve your fuel economy. Smooth and consistent driving is key to maximizing efficiency with the Altima’s CVT transmission.

Reduce unnecessary weight in your vehicle. Carrying excessive cargo in the trunk or back seat adds to the vehicle’s weight, impacting fuel consumption. Remove any items you don’t need to lighten the load.

Minimize idling time. If you anticipate stopping for more than a minute or two, turn off the engine. Idling consumes fuel without moving the vehicle, and the Altima’s engine restarts quickly when needed.

Use cruise control on the highway when appropriate. Maintaining a consistent speed can help optimize fuel efficiency, especially on long stretches of open road. Pay attention to traffic and disengage cruise control to maintain a safe following distance.
