TrueDelta Reviews the Real Gas Mileage of the Nissan Sentra

Nissan Sentra Real Gas Mileage: Pros
YearComment
2014 Aside from some speciality models that cannot be heavily optioned, the Sentra continues to top the rest of its segment in fuel economy, with EPA ratings of 30 mpg city, 39 highway. Well, almost. The new-for-2014 Mazda3 does a bit better with 30/40. Even with its base 1.8-liter engine the Kia Forte doesn't rate nearly as well, 25/36. If you want leather and such you're also getting the 2.0-liter engine, which is rated 24/36. The Sentra's trip computer substantiated its EPA estimates, and then some. On the highway cruising at 65 it reported a two-way average of 47 (up from 40 last year, probably due to warmer temps). In suburban driving the trip computer regularly reported averages of 36 to 37 (up from 32 last year), and on one run to my son's school with a very light foot on the pedals it topped 46. see full Nissan Sentra review

2002 4dr Sedan 175-horsepower 2.5L I4
6-speed manual FWD		 With MPG levels of 26 city/ 28 highway (even though you can go as far as 32 mpg highway and obtain an average of 26 mpg on mixed driving with the occasional engine redlining), the fuel economy of this car is pretty adequate. On stock form it will not drain your wallet, even when Nissan has the ECU tuned in the SE-R and SE-R Spec V to run a bit richer than in the Altima. It's no Prius but it's not as bad as, let's say, a modified Mazda rotary engine. Modifications like cold air intake and header will decrease some MPG but the change isn't too drastic either. see full Nissan Sentra review

2002 4dr Sedan turbocharged 250hp 2.7L V6
6-speed manual AWD		 For a car that requires 91+ octane, it would be nice if it got better gas mileage in city driving (around 16-18 mpg). The mileage on the highway is much better (up to 26 mpg). see full Audi A6 / S6 / RS6 review
