29 MPG combined is a solid fuel economy figure for the 2023 Nissan Altima AWD 2.5L 4-cylinder, a mid-size sedan engineered for everyday practicality and confident all-weather driving. This isn’t a sports sedan chasing lap times, nor is it aiming to be the thriftiest choice in the segment. Instead, it’s a sensible, comfortable, and readily available option for buyers prioritizing reliability and year-round usability without breaking the bank.

City and highway performance

The EPA estimates 26 MPG in the city and 34 MPG on the highway from the 2.5L Altima AWD. The city rating is respectable considering that all-wheel drive inherently adds some friction and weight, negatively impacting fuel consumption in stop-and-go traffic. The highway figure is where the Altima shines, proving to be an efficient long-distance cruiser. These numbers reflect the Altima’s engineering priorities, clearly favoring comfortable highway driving and fuel efficiency in those scenarios. The continuously variable transmission (CVT) plays a significant role here, constantly optimizing the engine’s RPM for maximum efficiency at cruising speeds. Because the engine speed does not directly correlate with the vehicle speed, the CVT transmission helps the engine stay in its most efficient power band as much as possible. Expect the highway fuel economy to fall off quickly when speeds rise above 75-80 mph. Aerodynamic drag has a significant impact at those velocities.

Annual fuel cost

According to the EPA, the 2023 Nissan Altima AWD 2.5L 4-cylinder will cost approximately $1,500 per year in fuel. This figure is based on driving 15,000 miles annually, using the EPA’s fuel consumption estimates of 26 city / 34 highway, and assumes current national average fuel prices. Of course, your individual fuel cost will vary depending on your driving habits, the actual price you pay at the pump, and the proportion of city versus highway driving.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy often deviates. Altima drivers can expect to see figures close to the EPA’s, provided they adhere to moderate driving habits. Aggressive acceleration, frequent hard braking, and extended idling will negatively impact your MPGs. Similarly, consistently exceeding speed limits on the highway will erode the 34 MPG rating. Drivers primarily using the Altima for shorter commutes in congested areas might see averages closer to the low 20s. However, those with predominantly highway driving should realistically achieve close to, or even slightly exceed, the EPA’s 34 MPG rating.

How it compares

The all-wheel-drive mid-size sedan segment offers a few alternatives, each with its own fuel economy profile. The Toyota Camry AWD, for example, is rated by the EPA at 25 MPG combined, making the Altima a slightly more fuel-efficient choice. Meanwhile, the Subaru Legacy, standard with AWD, achieves a combined EPA rating of 30 MPG, a small advantage over the Altima. The Honda Accord is not available with AWD, so you would have to opt for the smaller Civic if this feature is important to you.

It’s important to note that while some competitors might offer slightly better or worse MPG figures, the differences are often marginal and should be considered alongside other factors like price, features, and overall driving experience.

Tips to maximize efficiency

Gentle acceleration is key to squeezing more miles out of every gallon in the Altima. The CVT responds best to smooth throttle inputs. Avoid sudden bursts of acceleration, especially from a standstill. Instead, gradually increase your speed to minimize fuel consumption during the initial acceleration phase. Rapid acceleration increases friction and causes quick changes in the engine operation and transmission gearing.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. The recommended tire pressure for the Altima is typically found on a sticker inside the driver’s side doorjamb. Keeping your tires properly inflated will not only improve fuel efficiency but also extend the life of your tires.

Reduce unnecessary weight in the vehicle. Carrying extra cargo in the trunk adds weight, which reduces fuel economy, especially in the city. Remove any items that you don’t need for daily use, such as sporting equipment or tools. A lighter vehicle requires less energy to accelerate and maintain speed.

Minimize idling time. If you’re stopped for more than a minute, it’s more fuel-efficient to turn off the engine than to let it idle. Modern engines are designed to restart quickly and efficiently. Excessive idling wastes fuel and increases emissions.
