Unless I see new posts to the contrary, it appears that the expected fuel economy for the XB2 is in the range of 24-26mpg for combined city and highway driving. I was hoping for more, as I am now in the market for a new vehicle. Unless a few people can give better actual reports, looks like maybe I should have bought one of the old models.

Larger/heavier+bigger engine=less MPG..........

It all depends on how you drive... On my commute which is half hilly suburban w/stop signs and half 50 mph highway with stoplights, my mileage varies a lot based on how much "red mist" I get.

I have managed 31.6 with a light foot, steady acceleration, and A/C off.

With the A/C on, heavy acceleration and aggressive driving, (friday coming home through traffic?) I have gotten as little as 23.6.

Compared the first gen, if both are driven lightly, the 2nd gen gets about 3 mpg less.

Driven heavily, the 2nd gen gets about 6 less...but you get there a lot faster.

Thanks Bigfieroman:

That is the well thought reply I was looking for. Hopefully others will chime in and report as well, as I think it will help many in the buying decision. I put the same question out on the XD forum as well. I would need many more replys on both forums, but it appears so far that the 2008 EPA calculations are not far off from realilty.

My '06 XB w manual gets no less than 29 w/ 50% city, A/C on & somewhat heavy foot.

We live in Asheville NC so this is not a big city with a lot of traffic. We are averaging over 30 mpg in the city. This is with easy acceleration. Only road milage was fron a trip that was around 100 miles when we first got the car and it was 34.4 mpg. This is probably not typical but it definitely can get good fuel economy. By the way, this is an automatic.

Is this in the 2008? I noticed some others talking about their 06 and thought I would check.

My lease on my Tahoe is up the first of September and I've narrowed my choices of new vehicle down to the xB and a Rav 4. I am seriously leaning toward the xB. I was a bit disappointed in the lower fuel mileage, but understand they changed the motor and it is now heavier. I have a light foot and I only have heavy traffic in about the last 3-5 miles into work. the rest is 4 lane highway toward rural area, so I'm hoping I can get better mileage.

The milage was for the 2008 xB. We have about 800 miles on it so far so not a lot of data. However, the numbers in the original post are correct. May be taking it on a short trip next week. If so, will not milage again. We have three cars and are retired so we don't put many miles on any of them.

I have an auto 2nd gen 08 xB. The traffic here in hawaii has been somewhat heavier than usual, but my questions are:

Is it normal for my auto xB with 500miles on it, to get merely 17 avg miles per gallon?

Is it abnormal that I haven't gotten 200miles on a tank of gas yet, although this is my 4th tank?

Should I wait longer, maybe i'm still at the "break-in" period?

Any and all input is greatly appreciated as I intend to bring it back to the dealer if the condition persists.

17mpg.. sigh, and all of you are getting over 20 at least.

Thanks in advance!

If you want a fuel-efficient econobox like the Yaris, go with the XB1, if you want a Rabbit/Mazda 3 with GTI/Speed3 potential, go with the XB2. Personally I'd happily give up 2mpg for the ability to pass an 18 wheeler on a 2 lane or merge into traffic without risking life and limb but if those things aren't important to you, the Yaris or XB1 may better suit your needs.

BTW, I've been getting 22-30mpg from my XB2 with a 50/50 city/hwy average of 26mpg for the past 3000 miles and I have a very heavy right foot.

I'm in the same boat as revoluzion...and will be very curious to see if my situation improves as I put some more miles on.

I have a xb2 with about 750 miles. I'm getting18-19mpg avg. according to the computer. I reset it after each fillup. I also just started tracking it manually by recording mileage and fuel put back in. It's matching the computer so far.

I'm not upset, I came from a GMC Sierra getting only 12-13 mpg.

I drive like 99% in the city. All Stop and Go. I drive about 5 miles back and forth from my house to work every day. I've honestly onlu had it on the expressway twice.

So I didn't expect to be in the high twenties, but I really had hoped to be north of it.

I hope it will get better with time and miles as the engine breaks in.

I'd like to get the new TRD CAI, but this guy with the AEM one and replies to that are spooking me.

I know the K&N Cold Air Intake on my manual '06 xB gave me more horespower, but I never paid much attention to the mileage since I usually got around 32-33 mpg city/highway.

However, i know my mpg will be lower with my '08 xB. Will a CAI give better gas mileage, or just more horsepower?

I GET 12-16 MPG WITH MY NEW XB WITH 2300 MILES BUT THATS ON WENSDAYS WHEN I DELIVER THE PAPER.LOL

I get an average of 28 mpg. i don't really have a light foot most of the time however a lot of my commute is highway. Also a consideration would be altitude out here is only about 1k feet, the air is also super dry out here too. Highway i get about 36 w/the cruise set at 70-75. Can't complain when all the guys i work with are getting amywhere from 8-15 in their big, lifted trucks hehe.

do you use regular grade [87] or medium grade [89] in your xB?

i have always felt i got a little more power from using medium grade, but i am trying regular for now...

are you getting better mileage now? i just filled mine for the first time, and i got 250 miles on my first tank of gas the dealer gave me and i had a gallon or two left...

if not, definitely see the dealer to check it out!

You will not get appreciably more horsepower with midgrade or premium unless your car is designed for it.

I use 87 octane.

We finally took a weekend trip from Asheville NC through TN, VA and into southern WV. Total round trip was 447.3 miles. This included two days driving in Asheville, both interstate and two land roads as well as small towns. We used 13.036 gallons of Shell regular and got 34.3 mgp. The A/C was on for about two hours durning the trip. It looks like it is all how and where you drive.

I have a little "experiment" going on, mostly with the MPG calculator and why it fluctuates so much (over estimates.. Says 30mpg instead of the true 27 or 28 )... Early in my study but should be confirmed in the next few fill ups if there is any relation.

I used various "budget" gas stations and on my last two fill-ups switched to the top-tier gasoline, shell. With the lower quality fuels, my MPG was consistently around 2mpg above my true mpg.. On my first pure shell fill, my result was 28.1mpg, exact same reading on my calculator. I will filling up again on Friday and see if it's just as close, if so, it may solve why the MPG calculator may fluctuate, quality of gasoline going in. But I will do a few more fills after to see if there is a strong trend or just coincidence.

With the lower quality gasoline, I have had readings of 32 and 33 and such, and once I did the real math was as low as 29 and 30. So if Shell can come through and give accurate readings, it could be a big step in getting better MPG.

I can be FAR off with this, but it's worth a try! Ill keep ya updated.

I'm getting 24mpg with mostly city, I'd say about 70%. Only had it for 2 and a half weeks. Drive with A/C half the time, light foot never over 3,000 rpms (or whatever its called lol)

interesting numbers going on for me

when i first got it, i averaged around 23mpg
after a month till about 3 wks ago, i averaged 25.5mpg
2wks ago, i averaged 24.5mpg
this week, i am averaging 23.5mpg

i am thinking this has to be directly related to the colder temperatures in chicago

I am getting just below 22. All in town driving. It's only been on the freeway 2 times for short trips. Both under 5 miles. It has 1800 miles on it so far. I am taking an all highway trip this weekend and I will post my mileage Sunday when I get home.

People can get up to 43MPG when driven conservatively with gen1's, I'm getting around 33MPG and I've been accelerating aggressively.

Im in the same boat but my xB has 1800 miles on it and the best Ive averaged is 20.8mpg without a heavy foot. What do you guys suggest I tell the dealership?
Thanks in advance for all of your suggestions.

my Solara's mpg calculator was about 2 miles more than actual mileage also and i suspect it may be the same with others... i checked my mileage regularly while i owned it and it was always less than the displayed mpg...

the discrepency probably comes from engine idling time as the mileage calculator takes idle time into account when giving mpg results...

Sounds like the gas pump is not accurate - you can be getting short changed at the pump . . . it does happen. Some pumps will give you more gas than they say and some will give you less than they say. If you are pumping more than you think you shold be . . . change stations or change pumps.

I have a question for all the members, when you fill up what range mileage do u get at fillup? Mine shows me 244 miles, have any of you guys had any higher number?

I called the dealership to take her in and they said they cannot do anything unless it has a check engine light, but I'm taking her in anyways so they can keep a record of how many times I'm going to take the car in for the same reason if it doesnt get any better sooner, thanks again guys for your opinions.

I am on the high side in a xB1 so it will be higher but I get . . . about 425 miles on about 10 -10.3 gallons. I have seen threads here in SL with mileage all over the place with the xB2 and a lot depends upon how you drive. Best thing to do is to get your foot off the gas way before you start applying the brakes to slow down . . . all that distance you travel slowing down with your foot off the gas is 0.0 gallons of gas burning and really helps the mileage go up. If you find you still have to use a lot of brake then let off the gas even sooner the next time.
I have seen numbers in the low 20's to as high at almost 50 for the xB2. If yours rolls really easy in neutral on even the slightest grade then it should get good mileage. And as always keep over 32 psi in the tires.

the range estimate usually covers city driving from my experience - set one of your trip gauges if you are doing freeway driving and you will see the miles on the range estimator dropping slower than you are accumulating on the trip gauge when you get the higher mileage from being on the freeway...

i think mine said 277 on it when i got it - 14 gals @ 20mng = 280miles

but if you do highway driving you should get around 400 miles or so..
