The 2021 Nissan Sentra SR, with its 2.0L 4-cylinder engine, gets a combined fuel economy of 32 MPG. This is a good number for buyers who want affordability and modern features more than high performance. The Sentra SR is comfortable, reliable, and economical for daily driving, especially for younger buyers and urban commuters.
City and highway performance
The EPA estimates the Sentra SR gets 28 MPG in the city, a respectable number because of the engine tuning and the CVT’s role in optimizing efficiency when you stop and go. This number holds up well in real-world conditions, especially if you accelerate gently. On the open road, the Sentra SR gets 37 MPG on the highway. This makes it good for longer commutes and road trips, with a good mix of comfort and less gas. The continuously variable transmission (CVT) keeps the engine in its best operating range, which helps it get good highway numbers, even if it’s not the sportiest driving experience.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2021 Nissan Sentra SR at $1,350. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel prices when it was tested. Gas prices and how you drive can change this number. $1,350 is a good way to understand the Sentra SR’s running costs, showing that it is affordable compared to larger, less efficient vehicles.
Real-world expectations
The EPA results are from standardized tests, but the real-world MPG of the 2021 Sentra SR depends on how you drive, traffic, and even tire pressure. If you accelerate quickly often or drive in heavy traffic, the numbers may be a little lower than the EPA estimates. If you accelerate smoothly and drive at consistent speeds on the highway, you might get more than 37 MPG. Keeping the car maintained, with regular oil changes and properly inflated tires, will also help it get the best fuel economy.
How it compares
The 2021 Nissan Sentra SR’s fuel economy makes it competitive in the compact sedan class. For example, the Honda Civic LX gets around 30 MPG combined, while the Toyota Corolla LE gets about 33 MPG combined. The Hyundai Elantra SE also gets about 33 MPG combined. These differences can matter to buyers watching their budget. The Sentra’s numbers might be a little lower than some rivals, but its style, features, and value make it an appealing choice.

Tips to Maximize Efficiency
The Sentra SR’s CVT is designed to keep the engine in its most efficient range, but sudden, hard accelerations force it to simulate shifts, burning more fuel. Smooth, gradual acceleration will allow the CVT to do its job and keep the engine sipping fuel, which will give the smoothest ride too.
Regular maintenance is important to get the best fuel economy. Making sure your Sentra SR has properly inflated tires reduces rolling resistance and improves MPG. Check your tire pressure regularly and follow the manufacturer’s recommendations.
Avoid carrying unnecessary weight in the trunk or cabin. Extra weight increases the engine’s workload and lowers fuel efficiency. Emptying out any unnecessary items can make a noticeable difference, and provides the benefit of a cleaner interior!
Plan your routes to avoid congested areas and stop-and-go traffic, which significantly reduces fuel economy. Using navigation apps to find the most efficient route can not only save you time but also optimize fuel consumption.
Take advantage of the Sentra SR’s cruise control on the highway. Maintaining a consistent speed minimizes unnecessary acceleration and braking, which can boost your MPG on longer road trips.
