EPA Fuel Economy: 32 MPG Combined

The 2022 Nissan Altima 2.5L 4-cylinder S trim delivers solid fuel efficiency for a mid-size sedan with an EPA-estimated 32 MPG combined rating. This makes it an attractive option for drivers seeking a balance between performance, comfort, and reasonable fuel costs. The 2.5L four-cylinder engine pairs with a CVT automatic transmission to optimize fuel consumption across various driving conditions while maintaining adequate power for everyday driving. For those comparing mid-size sedans in today’s market, the Altima’s 32 MPG combined rating positions it competitively within its class.

Fuel efficiency has become increasingly important to vehicle buyers, and the 2022 Nissan Altima S addresses this concern without compromising the spacious interior and modern amenities that define the Altima lineup. The CVT transmission continuously adjusts gear ratios to keep the 2.5L engine operating at its most efficient RPM range, translating to better overall fuel economy than traditional automatic transmissions. Whether you’re commuting in urban environments or taking longer highway trips, the Altima’s fuel economy rating reflects real-world efficiency that Nissan engineers designed into this sedan.

City vs Highway Performance

The 2022 Altima 2.5L demonstrates notably different efficiency ratings between city and highway driving, which is typical for four-cylinder sedans. The EPA rating shows 28 MPG in city driving and 38 MPG on the highway—a significant 10 MPG difference that reflects distinct driving patterns. In city environments with frequent acceleration, deceleration, and idling, the engine works harder and consumes more fuel. The 28 MPG city rating is respectable for stop-and-go traffic, where even efficient CVT transmissions must manage constant gear adjustments to handle variable speeds.

Highway driving tells a different story, with the Altima achieving an impressive 38 MPG. At steady highway speeds, the CVT transmission locks into optimal ratios, the engine operates at consistent RPMs, and aerodynamic efficiency becomes a major factor. Drivers who spend significant time on interstates and rural highways will likely see fuel costs that skew toward the lower end of their budget calculations. The 10 MPG spread between city and highway ratings underscores why your actual fuel economy depends heavily on your typical driving habits.

Annual Fuel Cost

Calculating your annual fuel expenses with the 2022 Nissan Altima 2.5L S is straightforward using the EPA combined rating. Here’s the math with standard assumptions: assuming 15,000 miles driven annually and a gasoline price of $3.50 per gallon:

Calculation: 15,000 miles ÷ 32 MPG = 468.75 gallons annually. 468.75 gallons × $3.50 per gallon = $1,640.63 annual fuel cost.

This calculation uses the EPA combined rating of 32 MPG, which represents a balanced average of city and highway driving. Keep in mind that actual costs will vary based on your local gas prices, driving habits, and the percentage of city versus highway miles you accumulate. Drivers who take more highway trips might see annual fuel costs closer to $1,450, while those with primarily city driving might approach $1,750 annually. These estimates make it easier to budget for fuel expenses when considering the total cost of ownership.

Real-World MPG Expectations

While EPA ratings provide a standardized baseline, real-world fuel economy for the 2022 Altima 2.5L can vary based on several factors. Most owners report achieving within 1-2 MPG of the EPA combined estimate, meaning you can reasonably expect 30-34 MPG under typical driving conditions. Newer vehicles like the 2022 model benefit from modern engine management systems and improved aerodynamics that often help achieve EPA estimates more consistently than older vehicles.

Several driving habits influence your actual fuel economy. Aggressive acceleration and speeding significantly reduce efficiency, while maintaining steady speeds and smooth acceleration preserves the CVT’s optimal operating range. Regular maintenance—including tire pressure checks, oil changes, and air filter replacements—ensures your Altima performs at its engineered efficiency levels. Cold weather can temporarily reduce fuel economy by 10-15%, as engines require more fuel during warm-up periods and winter gasoline formulations are less energy-dense.

How It Compares

Comparing the 2022 Altima 2.5L to similar mid-size sedans reveals competitive positioning. The 2022 Toyota Camry with a 2.5L engine achieves 28 city and 39 highway (32 combined)—nearly identical to the Altima. The 2022 Honda Accord 2.0L turbo achieves 26 city and 38 highway (31 combined), offering slightly lower overall efficiency but with turbocharged performance. The 2022 Hyundai Sonata 2.5L reaches 28 city and 38 highway (32 combined), matching the Altima exactly. The Altima holds its own in this competitive segment, offering equivalent efficiency without premium pricing.

Tips to Maximize Efficiency

• Maintain proper tire pressure: Underinflated tires increase rolling resistance and reduce fuel economy by up to 3%. Check pressure monthly and before long trips.
• Avoid excessive idling: Modern engines use minimal fuel during start-up, so shut off the engine if stopped for more than 30 seconds rather than letting it idle.
• Use cruise control on highways: Maintaining constant speed reduces the work required from the CVT transmission and improves overall efficiency on longer drives.
• Remove unnecessary weight: Every 100 pounds of cargo reduces fuel economy by approximately 1%. Don’t leave items in the trunk unless needed.
• Plan efficient routes: Combining errands into one trip with minimal backtracking reduces overall miles driven and fuel consumption.

Frequently Asked Questions

Does the 2022 Altima S require premium gasoline? No, the 2.5L engine is designed for regular unleaded gasoline. Using premium fuel will not improve performance or efficiency and simply increases fuel costs.

How does CVT transmission affect fuel economy compared to traditional automatics? The CVT continuously adjusts gear ratios without fixed steps, keeping the engine at optimal RPMs for efficiency. This results in better fuel economy than conventional automatics, particularly in city driving.

Will actual MPG be significantly different from the EPA rating? Most drivers experience within 1-2 MPG of the EPA combined estimate. Individual results vary based on driving habits, road conditions, and maintenance, but the 32 MPG combined rating is a reliable benchmark for budgeting.

The 2022 Nissan Altima 2.5L 4-cylinder S trim represents practical fuel efficiency for mid-size sedan buyers. With a 32 MPG combined rating and realistic annual fuel costs around $1,640, it offers economical operation without sacrificing the comfort and features drivers expect. Whether comparing efficiency ratings or calculating long-term ownership costs, the Altima delivers dependable performance that justifies its reputation in the competitive mid-size sedan market.
