2002 Nissan Sentra

[SentraSE-R]

I'm amazed, myself. I've used ~340 gallons to drive 12,800 miles since I started hypermiling. If I'd gotten the EPA combined mileage, I'd have used 246 more gallons, at a cost of $671. That's a fair amount of savings for that amount of driving.

I just got done trimming Sentra fat yesterday. I've driven 68 miles since and refilled the tank with two gallons to where it was before I took everything out. I calculated 33- 34 MPG, with spirited driving. You know I had to test it out.

This is the new, rennovated cockpit!



Stuntin' on them 14"s.

I stripped the seats out of my B-14 SE-R in preparation for running it at the drag strip. Put all the stuff in a pile on the scale, and was really disappointed to find it only added up to ~100 lbs.

Every little bit helps, but we had an Ecomodder northern CA meet a few weeks ago, and I did a clinic with two other guys in my xB. Even with 300 lbs more weight, I was still able to pull 59 mpg on a couple legs of the driving route. Very little, if any, difference from driving the route alone.

Weight has little effect on getting better MPG in continuous (highway) driving. It has more effect (but still minimal) in city stop-and-go, and even then interior weight removal is less noticeable than, say, unsprung rotating weight (wheels, tires, brakes, etc.).

That sucks. I removed a great deal and it's made a big difference.

Your driving plus the xB's already high fuel economy make a good combination for getting those numbers.

Sure it does. It's easier for the car to get up to speed now, since it's got a lighter load. I'm sure that if you were to consider the amount of work it takes for my 1.8L to maintain a calculated 168lbs (removed from vehicle) going at x rate of speed, then it would certainly prove to be beneficial. As for city driving, the effects have exceeded my expectations. Again, getting up to speed isn't as strenous. Maneuvers that required full throttle application need less than 3.5RPM to get me going. (ex. Right turns with oncoming traffic) I've recorded a 2-3 MPG improvement over the stock furnishings. I can't comment on the effect of unsprung weight, because all of those parts are stock on my car. Don't know how you can say that it's "less noticable" than unsprung weight. Replacing my wheels, which we'll say weigh maybe 20 lbs a pop, versus taking out 168lbs of furnishings from my lovely interior; Of the two, which one would be more significant? Without question, it would be the latter.
