2024 Nissan Altima 2.5L Fuel Economy: Complete MPG Guide

EPA Fuel Economy: 32 MPG Combined

The 2024 Nissan Altima 2.5L 4-cylinder S delivers a combined EPA fuel economy rating of 32 miles per gallon, making it an efficient choice in the midsize sedan segment. This rating reflects real-world driving conditions based on EPA testing procedures that simulate both city and highway driving patterns. The 2.5L four-cylinder engine paired with the CVT automatic transmission creates a practical balance between performance and fuel efficiency, allowing drivers to enjoy responsive acceleration without excessive fuel consumption.

For drivers prioritizing fuel economy in a midsize sedan, the 2024 Altima’s 32 MPG combined rating positions it as a competitive option. This efficiency level means fewer trips to the gas pump and reduced fuel expenses throughout the year, which adds up to meaningful savings over the vehicle’s ownership period. The consistent performance across various driving conditions makes the Altima a reliable choice for commuters and long-distance travelers alike.

City vs Highway Performance

The EPA ratings for the 2024 Nissan Altima 2.5L S show distinct differences between city and highway driving. In the city, the vehicle achieves 28 MPG, which reflects the stop-and-go nature of urban driving with frequent acceleration and braking. On the highway, the Altima performs noticeably better at 38 MPG, taking advantage of sustained speeds and less demanding engine operation. The 10-MPG difference between city and highway ratings is typical for vehicles with conventional powertrains and demonstrates how driving patterns significantly impact fuel consumption.

Highway driving favors the Altima’s CVT transmission, which can maintain optimal engine RPMs for fuel efficiency during cruising speeds. City driving requires more aggressive throttle inputs and frequent deceleration, factors that naturally reduce overall efficiency. Drivers who spend more time on highways can expect fuel economy closer to the 38 MPG rating, while those in heavy urban traffic will likely see figures nearer to the 28 MPG city rating.

Annual Fuel Cost

Based on EPA estimates and average driving patterns, here’s the annual fuel cost calculation for the 2024 Nissan Altima 2.5L S:

Annual Fuel Cost Calculation:

• Annual mileage: 15,000 miles
• Combined MPG rating: 32
• Gallons needed annually: 15,000 ÷ 32 = 468.75 gallons
• Current average gasoline price: $3.50 per gallon
• Estimated annual fuel cost: 468.75 × $3.50 = $1,640.63

This calculation assumes consistent fuel prices and average driving habits. Drivers who accumulate more highway miles may see slightly lower annual costs due to the 38 MPG highway rating, while those with predominantly city driving might experience slightly higher costs. Gasoline prices fluctuate based on market conditions, so actual costs may vary from this estimate.

Real-World MPG Expectations

While EPA ratings provide standardized benchmarks, real-world fuel economy depends on numerous factors including driving habits, road conditions, vehicle maintenance, and weather. Most 2024 Nissan Altima 2.5L owners report fuel economy within 1-2 MPG of the EPA combined rating, though some achieve results above or below this range.

To achieve fuel economy closer to the EPA estimates, maintain proper tire pressure, avoid excessive idling, accelerate gradually, and keep the engine properly maintained with regular oil changes. Aggressive driving, excessive speed on highways, and carrying heavy loads will reduce efficiency below the rated 32 MPG combined figure.

How It Compares

The 2024 Nissan Altima 2.5L S’s 32 MPG combined rating compares favorably within the midsize sedan category. The Honda Accord with a 1.5L turbocharged engine achieves 33 MPG combined, offering slightly better efficiency at the cost of smaller engine displacement. The Toyota Camry with a 2.5L four-cylinder delivers 31 MPG combined, placing it just below the Altima’s rating. The Hyundai Sonata with a 2.5L engine achieves 32 MPG combined, matching the Altima’s efficiency exactly. These comparisons show that the Altima remains competitive for fuel-conscious buyers in this segment.

Tips to Maximize Efficiency

• Maintain proper tire pressure: Check tire pressure monthly and inflate to the recommended PSI found on the driver’s door jamb. Underinflated tires increase rolling resistance and reduce fuel economy.
• Practice smooth acceleration: Gradual acceleration reduces fuel consumption compared to rapid throttle inputs. The CVT transmission performs most efficiently with steady engine speeds.
• Avoid excessive idling: Turn off the engine if stopped for more than 10 seconds. Idling consumes fuel without producing any forward motion.
• Keep up with maintenance: Regular oil changes with the recommended viscosity, fresh air filters, and proper wheel alignment all contribute to optimal fuel economy.
• Remove excess weight: Clear unnecessary items from the trunk and roof racks. Every 100 pounds of additional weight reduces fuel economy by approximately 1-2 percent.

Frequently Asked Questions

Q: What is the EPA fuel economy rating for the 2024 Nissan Altima 2.5L S?
A: The EPA combined rating is 32 MPG, with 28 MPG in the city and 38 MPG on the highway.

Q: Can I achieve better than 32 MPG combined with the 2024 Altima?
A: Drivers who primarily drive highway routes may exceed the combined rating, as the highway rating of 38 MPG is significantly higher. Consistent highway driving could push combined averages toward 35-36 MPG.

Q: How often will I need to refuel the 2024 Altima with a typical 15-gallon tank?
A: At 32 MPG combined, a full tank provides approximately 480 miles of range, meaning most drivers will refuel every 1.5 to 2 weeks with typical commuting patterns.

The 2024 Nissan Altima 2.5L S provides practical fuel efficiency for buyers seeking reliable midsize sedan performance without excessive fuel consumption. Its 32 MPG combined rating, responsive 2.5L engine, and smooth CVT transmission create an efficient daily driver suitable for various driving conditions.
