The 2015 Nissan Maxima 3.5 S gets 22 MPG combined. It’s a sedan that focuses on driving enjoyment and a touch of luxury rather than prioritizing fuel efficiency. It appeals to drivers who appreciate a responsive V6 engine and a comfortable, well-equipped cabin, and engaging performance. The Maxima delivers a near-luxury experience blended with strong acceleration, and the fuel economy reflects this.

City and highway performance

The EPA estimates are 19 MPG in the city and 28 MPG on the highway, which offer a more complete picture of the 2015 Maxima 3.5 S’s fuel consumption. The 19 MPG city rating shows its ability to accelerate quickly, a characteristic that buyers in urban areas often value. The 28 MPG highway figure is respectable for a V6-powered sedan. It allows for comfortable and economical long-distance driving. The CVT transmission optimizes engine speed for efficiency during steady-state driving while also enabling quick bursts of power when needed.

Annual fuel cost

According to the EPA, the average annual fuel cost for the 2015 Nissan Maxima 3.5 S is $2,386. This is based on driving 15,000 miles per year and using the EPA’s estimated combined fuel economy of 22 MPG. The calculation includes the national average fuel price at the time of testing. Your actual fuel costs will vary depending on your driving, local fuel prices, and driving conditions.

Real-world expectations

While EPA estimates provide a benchmark, real-world fuel economy can differ. Maxima 3.5 S owners often report numbers close to the EPA figures, but aggressive driving or consistent city driving can decrease those numbers. However, those who focus on fuel efficiency and drive on the highway may see slightly better results than the official ratings. Understanding your driving style is critical to predicting your fuel costs.

How it compares

The 2015 Maxima 3.5 S’s fuel economy is in the middle of the V6-powered sedan segment. For example, a 2015 Toyota Avalon gets 21 MPG city and 31 MPG highway with its V6, which is more efficient on the open road. The 2015 Chevrolet Impala with the 3.6L V6 is rated at 18 MPG city and 28 MPG highway, placing it near the Maxima in overall consumption. Buyers considering the Maxima are likely cross-shopping these models, along with the Acura TLX (the V6 version, not the 4-cylinder) which delivers similar economy. They are likely trading some MPG for the sporty feel and look of the Maxima.

Tips to maximize efficiency

The Maxima’s CVT transmission helps efficiency, and is also responsive to throttle input. Avoid aggressive acceleration and hard braking, as these driving habits reduce fuel economy. Gradual acceleration allows the CVT to operate efficiently.

Tire pressure is important for fuel efficiency. Check your tire pressure frequently and ensure it matches the manufacturer’s settings on the doorjamb sticker. Underinflated tires increase rolling resistance, leading to lower MPG figures.

The 3.5L V6 in the 2015 Maxima benefits from regular maintenance. Keep up with scheduled oil changes and air filter replacements to keep the engine running well. A well-maintained engine is more efficient.

Minimize idling time. If you’re stopped for a while, turn off the engine. Too much idling consumes fuel, especially affecting city fuel economy. This is especially helpful if you wait in the Maxima often, such as while picking a child up from school or waiting in line for errands.

Consider using cruise control on the highway to maintain a consistent speed and get better gas mileage. Cruise control helps prevent unintentional speed changes, which can waste fuel. The Maxima’s comfortable seats and smooth ride make it ideal for long road trips. You can find all Nissan fuel economy data on our website.
