Anyone gets >40mpg consistently in his/her xb?

Here's a link to my Ecoomodder fuel log. I Pulse and glide a lot on country roads, but the main things I do are go slow, coast a lot, and plan my trips to avoid short trips.

Here's a link to my hypermiling thread on ClubxB. It has a lot of hypermiling tips in it. I'll be happy to discuss them here or there.

And I do have grill blocks & low-drag mirrors.

cool i will definitely be reading your thread! ive gotten only through page 1 so far and immediately i have to say something. sure the xB is not going to win any quarter mile races and i have never been a power type of person, but I love a fun to drive good handling car and i find the xB to be a LOT of fun to drive (with some suspension upgrades), and there is enough pep to get it out of the corners quick enough to induce a smile my dad told me a long time ago that it is more fun to drive a slow car fast than a fast car slow. my car is equipped with hotchkis springs, trd japan struts, and hotchkis sway bars and it really is a lot of fun. i used to autox an rx8 for 3 years, a miata for 2.5 years, and am now running my friend's mr2 (1st gen) just started. i still maintain that the xB is one of my favorite cars of all time because it is so much fun to drive, gets excellent FE, and is so big on the inside yet looks small on the outside. plus i think it looks nice =P

i do agree w/ your statement about motorcycles though. I ride 600s which get excellent FE, look cool, go fast in a straight line (though i ride slow anyway), and I can park it just about anywhere. the things i dont like about motorcycles is riding in the rain and that i hear though they get better FE, they are more polluting. i hope that changes soon

I just finished reading the 26 pages in this thread. Some of the participants like Zman, JanGeo, and Blackbelt were here when I first signed up.

To answer one of your original questions, the xB does have deceleration fuel cut-off. DFCO comes into play when the engine throttle position sensor notices a drop to idle position with the transmission in gear and engine rpm >1500 (in our xBs). So, you're correct that you can coast down hills and to stops using no fuel under those conditions. However, your coasting distances are shortened by coasting in gear, and it's possible you'll get better fuel economy coasting in neutral for longer distances, even with engine on.

DFCO varies with different cars. My wife's 2006 Hyundai Elantra doesn't have it. My 2002 Nissan Sentra only went into DFCO above 2500 rpm, which was ~65 mph in 6th gear. That made DFCO mostly useless for me, since I don't drive >65 mph very often.

i use DFCO on steeper hills and when im actually trying to slow down. whenever i need to maintain momentum i will just throw it into neutral. unfortunately there is no where here when i can utilize EOC for more than half a mile to a mile at a time so i don't even try anymore. i do shut off the engine at most stop lights, but i hate when the light changes right after i shut it off :P

Which island are you on? The four I've visited were all tough for hypermiling, Unless you live and work in the boondocks, your FE will go to pieces with tourist traffic and congestion. At least, that's the impression I got.

[scsi]

thanks, that is actually very reassuring haha.. maybe i can blame at least some of my poor mpg to my area (i live on oahu)

[scsi]

btw, were you able to confirm that DFCO stops at 1500rpm? i have heard it was 1100 which is just a little above idle.

[SentraSE-R]

Yes, I've confirmed DFCO starts down to 1500 rpm in our xBs. It holds down to lower rpms, but you have to be ~1500 rpm to kick it in. My Sentra had to be >2500 rpm, which was >65 mph in 6th gear, so it was essentially useless to me. On our xBs, DFCO comes in at 35 mph in 5th gear, so it's available and useful much more often.

what is the best way to go uphill? i hear a lot about coasting down hills and such but im constantly confronted with hills of all sizes.

[SentraSE-R]

It depends on the hill. I DWL or use cruise control up the big/long ones. I P&G up the little ones. If they're going to need more than 2 pulses, I slog up them.
