The 2021 Nissan Maxima gets 24 MPG combined. It’s not a number that will win any awards for lower fuel costs, but it’s also a figure that doesn’t deter the Maxima’s fanbase. This isn’t a car bought by penny-pinchers scrutinizing every tenth of a mile per gallon. The Maxima buyer seeks a comfortable, stylish sedan with a reliable V6 engine and a dash of sporty flair, and they accept the fuel economy that comes with it.

City and highway performance

The EPA estimates provide a breakdown beyond the combined figure. The 2021 Maxima is rated at 20 MPG in the city and 30 MPG on the highway. That 10 MPG difference reveals much about the Maxima’s character. The city figure reflects the inherent inefficiency of stop-and-go driving, something that impacts all vehicles. However, the highway number demonstrates the 3.5L V6’s potential for respectable fuel economy when cruising at steady speeds. Drivers who prioritize highway miles are likely to see numbers closer to that 30 MPG figure, further softening the blow of the overall combined rating. The automatic (AV-S7) transmission is tuned to maximize fuel economy, which is especially apparent during constant highway speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Nissan Maxima at precisely $2,400. This number is calculated based on driving 15,000 miles per year, using the national average fuel price at the time of calculation. Obviously, your individual fuel costs could be higher or lower depending on how much you drive, where you drive (city vs. highway), and the prevailing fuel prices in your area. However, that $2,400 figure provides a standardized benchmark for comparison. It allows potential buyers to weigh the Maxima’s running costs against those of other vehicles they may be considering.

Real-world expectations

The EPA estimates are a starting point; real-world driving habits and conditions will always impact your actual MPG. Aggressive acceleration, frequent hard braking, and neglecting routine maintenance can all contribute to lower fuel economy. Conversely, smooth driving, anticipating traffic, and ensuring proper tire inflation can help align your results more closely with the EPA figures. Many owners report achieving numbers slightly above or below the EPA estimates, depending largely on their driving styles and the type of roads they typically use.

How it compares

The Maxima is in a competitive segment with a range of vehicles offering diverse powertrains. A direct competitor like the Toyota Avalon, specifically with its V6 engine, achieves a nearly identical 22 city / 32 highway EPA estimate. The Avalon generally offers a smoother, quiet ride and the gap in MPG is negligible. The Kia Stinger, particularly the GT trim with its turbocharged V6, provides a sportier driving experience but sacrifices some fuel economy in the process (17 city / 24 highway). Drivers considering the Stinger prioritize performance over fuel efficiency. For those willing to sacrifice some engine power for better fuel economy, the Honda Accord 2.0T offers an alternative, achieving 22 city / 32 highway. These numbers highlight where the Maxima sits: a compromise between pure fuel efficiency and a satisfying driving experience. For a broader perspective, explore all Nissan fuel economy data.

Tips to maximize efficiency

Use the Maxima’s cruise control, especially on long highway journeys. Maintaining a consistent speed not only reduces driver fatigue but can also significantly improve fuel economy. The automatic transmission is already tuned for efficiency, but cruise control allows it to function even more effectively, minimizing unnecessary shifts and maintaining optimal engine RPM.

Pay close attention to tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consequently burning more fuel. Consult the sticker inside the driver’s side doorjamb for the recommended tire pressure for your Maxima, and check your tires regularly, especially during temperature changes. Even a few PSI below the recommended level can negatively impact fuel economy.

Avoid aggressive driving habits. Rapid acceleration and hard braking dramatically reduce fuel efficiency. Anticipate traffic and maintain a smooth, consistent pace. The Maxima’s smooth and responsive V6 engine is best enjoyed with a measured approach, allowing it to deliver both performance and reasonable fuel economy. See the MAXIMA MPG across all years to determine if there are specific models or years that work best for your needs.

Keep your Maxima properly maintained. Regular oil changes, air filter replacements, and spark plug maintenance all contribute to optimal engine performance and fuel efficiency. A well-maintained engine operates more efficiently, using less fuel to produce the same amount of power. Consult your owner’s manual for the recommended maintenance schedule and stick to it.
