EPA Fuel Economy: 31 MPG Combined

The 2021 Nissan Rogue 2.5L 4-cylinder S trim delivers a combined fuel economy rating of 31 MPG, making it an efficient choice in the compact crossover segment. This respectable efficiency rating comes from the vehicle’s naturally aspirated 2.5-liter four-cylinder engine paired with a continuously variable transmission (CVT). The combination of modern engine technology and transmission optimization allows the Rogue to balance everyday driving performance with reasonable fuel consumption for its class.

With a combined rating of 31 MPG, the 2021 Nissan Rogue S demonstrates that you don’t need a hybrid or smaller engine to achieve solid fuel economy. The CVT automatic transmission plays a key role in these numbers, constantly adjusting engine RPMs to maintain peak efficiency across various driving conditions. For drivers who travel the typical 15,000 miles annually, this fuel economy translates to manageable fuel costs while maintaining the practicality and space that makes the Rogue a popular choice for families and commuters.

City vs Highway Performance

The EPA ratings break down the Rogue’s efficiency into two distinct driving scenarios: 29 MPG in city driving and 35 MPG on the highway. The 6 MPG difference between these ratings is typical for most vehicles and reflects the varying demands of different driving environments. In city driving, the Rogue’s 2.5L engine experiences frequent acceleration, deceleration, and idling, which naturally consumes more fuel. Stop-and-go traffic and lower average speeds mean the engine works harder and spends more time in less efficient operating ranges.

Highway driving tells a different story, with the Rogue achieving 35 MPG on the open road. At steady highway speeds, the engine operates at lower RPMs with minimal throttle adjustments, allowing it to run more efficiently. The CVT transmission excels in highway conditions by maintaining optimal engine speed without the inherent inefficiencies of traditional automatic transmissions. If your driving consists primarily of highway commuting or long-distance trips, you can expect to see fuel economy closer to the 35 MPG rating, while predominantly city drivers will experience figures closer to 29 MPG.

Annual Fuel Cost

Understanding your annual fuel expenses helps with budgeting and ownership planning. Based on the EPA combined rating of 31 MPG, annual mileage of 15,000 miles, and a gasoline price of $3.50 per gallon, here’s the calculation:

15,000 miles ÷ 31 MPG = 484 gallons per year
484 gallons × $3.50 per gallon = $1,694 in annual fuel costs

This estimate assumes consistent driving patterns and average fuel prices. Actual costs will vary based on your local gasoline prices, driving habits, and the mix of city versus highway driving you do. If you drive more highway miles, your annual fuel cost could be lower due to the superior 35 MPG highway rating. Conversely, primarily city driving would increase your annual expense closer to $1,800 or more.

Real-World MPG Expectations

EPA ratings provide a standardized baseline, but real-world fuel economy depends on multiple factors. Most 2021 Nissan Rogue owners report combined fuel economy within 1-3 MPG of the EPA estimate, meaning you might see anywhere from 28-34 MPG depending on your driving patterns. Aggressive acceleration, excessive idling, and frequent short trips can reduce efficiency, while smooth acceleration and highway driving tend to achieve or exceed ratings.

To maximize your real-world fuel economy, maintain proper tire pressure—underinflated tires increase rolling resistance and reduce MPG. Keep up with scheduled maintenance including oil changes and air filter replacements, as a well-maintained engine runs more efficiently. Remove unnecessary weight from your vehicle, avoid excessive idling, and use cruise control on highways to maintain steady speeds. Additionally, plan routes to minimize stop-and-go driving when possible.

How It Compares

The 2021 Nissan Rogue’s 31 MPG combined rating is competitive within the compact crossover class. The 2021 Honda CR-V, a direct competitor with a similar 2.0L engine and CVT transmission, achieves 28 MPG combined, making the Rogue slightly more efficient. The 2021 Toyota RAV4 with its 2.5L engine and eight-speed automatic reaches 28 MPG combined as well. The Rogue’s CVT transmission gives it an advantage in fuel economy compared to these traditional automatic competitors. If fuel economy is your primary concern in this segment, the Rogue S is a strong choice.

Tips to Maximize Efficiency

• Maintain steady speeds: Use cruise control on highways to avoid speed fluctuations that waste fuel.
• Accelerate smoothly: Avoid rapid acceleration and hard braking, which increase fuel consumption significantly.
• Check tire pressure regularly: Keep tires inflated to the recommended PSI found on the driver’s door jamb for optimal fuel economy.
• Plan efficient routes: Combine errands into one trip and avoid peak traffic times when possible to reduce idle time.
• Reduce excess weight: Remove roof racks and unnecessary cargo to decrease the engine’s workload.

Frequently Asked Questions

Q: What fuel type does the 2021 Nissan Rogue S require?
A: The 2021 Rogue S uses regular unleaded gasoline. Using premium fuel will not improve fuel economy or performance.

Q: Can I improve the 31 MPG rating through modifications?
A: While major engine modifications could theoretically alter fuel economy, the best approach is maintaining the vehicle properly and practicing efficient driving habits. Warranty-voiding modifications typically aren’t worth the risk.

Q: Is 31 MPG good for a 2.5L crossover?
A: Yes, 31 MPG combined is very respectable for a 2.5L four-cylinder crossover. The CVT transmission is instrumental in achieving this efficiency rating.

The 2021 Nissan Rogue 2.5L S trim offers practical fuel economy without compromising the space and capability that compact crossovers are known for. With a combined rating of 31 MPG and reasonable annual fuel costs around $1,694, it remains an economical choice for everyday driving.
