31 MPG combined. That defines the 2015 Nissan Altima 2.5L, a number that speaks volumes about the car’s mission: affordable, reliable, and reasonably efficient transportation for those who prioritize value and practicality. This isn’t a sports sedan disguised as a family car; it’s a comfortable commuter designed for everyday driving, and the fuel economy reflects that.

City and highway performance

The EPA estimates 27 MPG in the city and a more impressive 37 MPG on the highway. The highway figure is particularly attractive for drivers who rack up significant miles on longer commutes or road trips. The continuously variable transmission (CVT) plays a critical role here, constantly adjusting the gear ratio to keep the engine operating at its most efficient range.

City driving, with its stop-and-go nature, naturally reduces fuel economy, but even then, the Altima’s 2.5L four-cylinder manages a respectable showing. The CVT, while prioritizing efficiency, can sometimes feel a bit less responsive than a traditional automatic, a tradeoff some drivers gladly accept for the improved MPG.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2015 Nissan Altima 2.5L is $1,400. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel prices at the time of calculation. Your actual fuel costs will vary depending on your driving habits, the type of driving you do (more city vs. highway), and the price of gasoline in your area. This estimate provides a useful benchmark for comparing the Altima’s fuel costs to other vehicles in its class. For buyers on a budget, this annual running cost is a critical piece of the ownership puzzle.

Real-world expectations

While the EPA numbers offer a standardized comparison, real-world fuel economy can vary. Many owners report achieving figures close to the EPA estimates on long highway drives. Aggressive driving, frequent short trips, and carrying heavy loads will all negatively impact fuel consumption. Factors like tire pressure and vehicle maintenance also play a role.

If you prioritize fuel economy, adopting a smooth driving style and ensuring your Altima is properly maintained will help you get closer to the advertised MPG. Remember that these numbers apply to a car in good mechanical condition. An aging or poorly maintained Altima may see its fuel economy decline over time.

How it compares

In the mid-size sedan segment, the 2015 Altima’s fuel economy is competitive, but not class-leading. For example, the 2015 Toyota Camry LE with its 2.5L engine achieves an EPA-estimated 25 MPG city and 35 MPG highway. The Honda Accord LX from the same year, also with a 2.4L four-cylinder, boasts estimates of 27 MPG city and 36 MPG highway. The Ford Fusion SE with the 1.5L EcoBoost engine is rated at 25 MPG city and 37 MPG highway.

These comparisons are essential for buyers looking for the most efficient option. While the Altima’s numbers are right in the mix, features like comfort and price might sway buyers who accept slightly lower MPG in exchange.

Tips to maximize efficiency

The Altima’s CVT is designed for efficiency, so avoid aggressive acceleration. A smooth, gradual increase in speed will allow the transmission to find the optimal gear ratio for less gas. Sudden bursts of power force it to work harder and burn more fuel.

Keep your tires properly inflated. Underinflated tires create more rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side doorjamb. Even a few PSI difference can impact your gas mileage.

Minimize idling. If you’re stopped for more than a minute or two, turn off the engine. Idling consumes fuel without moving the car, and it’s a common source of wasted gas, especially in city driving with lots of stoplights. The Altima’s engine restarts quickly and easily, so there’s little inconvenience.

Regular maintenance is important for maintaining optimal fuel economy. Keep your engine properly tuned, and change the air filter and spark plugs according to the manufacturer’s recommendations. A well-maintained engine runs more efficiently, saving you money at the pump. Check all Nissan fuel economy data to see how other models fare.
