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

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

This car obtains awful fuel economy in the city. Mine averages about 20 on a good day in stop and go traffic. On the highway, it has gotten as high as 37, but typically hovers around 30-33. Be prepared to visit the pump often, it takes about 12-13 gallons see full Nissan Sentra review

2007 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD
My average for the life of the car is 21MPG. Not too bad for a car with this power and my lead foot. see full Infiniti G review

2013 4dr Sedan 328-horsepower 3.7L V6

Can live with it because of the performance, but wish the mileage was better and premium fuel was not required. see full Infiniti G review

What the powertrain giveth, the fuel economy taketh away. Nissan's VQ engines just seem to be thirsty - if you commute in heavy traffic, especially for short trips, don't be surprised at 15.5-16 mpg tanks. I don't know what mostly-highway commuting would look like, but maybe 22-25 mpg depending on driving style. see full Infiniti G review
2010 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD
To be honest, it is exactly what I expected, so no real beefs with it. That said, if you are looking for a car that gets better than 19 or so combined, this is not it. Decent freeway miles (24-27/g) but in city it is hard to beat 16/g. see full Infiniti G review

You do not buy a performance car and expect to get good gas mileage. At a 5 mpg or greater difference from my last car, it is taking some getting used too. see full Infiniti G review

With such a large displaced engine and so much power you will find that you will have so-so mpg if you drive mainly in the city like I do. Especially if you are a "spirited" driver like I tend to be. I am averaging about 14-16mpg 95% city. On the highway its a different story. I have averaged up to 28mpg @ 78mph, I kind of wish I drove more on the highway. see full Infiniti G review

6-speed manual RWD
While not terrible, ~20mpg is by no means phenomenal. Relatively comparable cars get ~23-27mpg, but typically also have smaller engines which explains a good portion of the difference. see full Infiniti G review
