Wheel size is the only thing separating the trims at the pump. S and SV on 16s and the SL on 17s all carry Nissan's 30/38/33 estimate, while the SR's 18-inch wheels and stickier 215/45R18 tires cost it one to two mpg per cycle at 29/36/32. The SL's rating is actually a 2027 improvement; Nissan's new spec sheet promotes it out of the lower group it occupied last year.

Keep the wording straight when you comparison shop: these are EPA-estimated figures published by Nissan, published ahead of official EPA figures posting to the federal fueleconomy.gov database. Standard idle stop/start helps the city figure hold up in real traffic.

• S, SV, SL: EPA-estimated 30/38/33 mpg
• SR: EPA-estimated 29/36/32 mpg on 18-inch wheels
• SL rating improved for 2027 per Nissan
• Idle stop/start standard across the lineup
• Runs happily on regular unleaded

All four trims share one 12.4-gallon tank, carried over unchanged from the 2026 redesign. That consistency means the trim you pick changes your range only through its mpg rating, never through a smaller tank hiding in the fine print.

Paired with regular-grade fuel, the modest tank keeps each fill-up affordable, and at 33 combined mpg you are not visiting the pump often anyway. For a Homosassa-to-Tampa commuter, that is the difference between planning fuel stops and forgetting about them.

• 12.4-gallon tank on every 2027 Sentra
• Identical capacity to the 2026 model
• Regular unleaded recommended, no premium needed
• Low per-fill cost at compact-car volumes

Run the math on the 12.4-gallon tank and Nissan's estimates: S, SV, and SL trims compute to 372 miles city, 471 highway, and 409 combined, while the SR works out to 360, 446, and 397. Those are calculated figures, not a published Nissan range, but they frame the car's endurance well.

In practical Nature Coast terms, a computed 400-plus miles of combined range covers a week of US-19 errands between Homosassa and Crystal River, or a Tampa airport round trip with most of a tank to spare. Air conditioning season and a full car will trim any estimate, so treat these as a ceiling.

• Computed range up to 471 highway miles
• 409 combined miles on S, SV, and SL, computed
• SR computes to 397 combined miles
• Calculated from EPA estimates and tank size
