Not happy with MPGs

You'd assume that driving faster means you'll get there sooner, and use less gas, but sadly, the opposite is true. On balance (time vs. mpg), a measly 45 gets the best mileage. Add all that, plus the bigger engine and your hills, your mileage will suffer. At least you don't live in Hawaii, where I'm paying $3.30/gal.
Oh, by the way, the coefficient is actually .32.

I went from 28.5 to 25.5, mostly by going from 90% hwy to almost 50%. I still use cruise as much and as often as possible. Im sure the rims are hurting you a bit too. When you drive around, where does the tranny normally shift. I found I was able to get the best mileage at 2500rpm shifts or less. Of course thats all out the window now. I'm hanging at 25.5, equal city/hwy driving, and plenty of spirited stuff.

The factory steel wheels weigh 23# each. I weighed them. I am unable to get a weight anywere from the internet on my wheels "MB Wheels - Octane". Sold exclusively by discount tire. Can anyone guess what these weigh? This is a cheap one piece wheel by the way. The screws are fake.

Everyone thats griping about the fuel milage.....next time, do some research before you buy and if you really wanted good fuel economy, you would have purcahsed a Prius, Yaris or Corolla. The xB was designed to be an urban commuting vehicle, not a hypermiling or interstate cruising auto.

I knew what mileage to expect when I bought my xB.... but I'm getting no where near what the window sticker says.
I'm *lucky* if I get 20 city, 22-23 highway... and that's totally "babying" the throttle. It's been like this since day one. I've now had my xB for 6 months and just hit 2,500 miles on odometer.
Oh.... I've got an automatic w/ 19" TRD wheels & a CAI.
With all that being said though, I still absolutely LOVE my little "Doom Buggy."

We were getting like 24.5 but it seems since the rims and tires (18") now get 23.5.
It's a 2010 and we drive with ac on all the time even if windows are open. Windows are tinted 2% front and 1% back so it stays cool inside.lol
It just ____es me off that I can't get to 300miles for a tank. I will probably get a CAI or a SRI soon. Also we use 87gas and full synthetic mobil1 oil have about 5K-6K miles on car.

To the poster that said to do research before you buy a car for mileage. I did plenty of research. Unfortunately my research was the internet and the window sticker. I read many reports of the scion mpg ratings much lower than actual experiences with lots of people reporting 30 mpg on hwy. Unfortunately those are proving very false. I expected to get at least 3 - 4 mpgs than what I am getting now. I was looking at a honda fit 33 mpg hwy and civic 36 mpg. I figured for the extra $300 a year in fuel costs and the fact that the xB was more comfortable, rode better, safer, cooler, it was a no-brainer. I still love my car, just want to squeeze more out of it without driving 45 on the hwy. My matrix I had got 30 consistently with the same commute route I am doing now. So based on 12k miles a year, it cost me $275 more a year to drive the scion. That is $5.23 more per week. I guess I will just cut out some of that starbucks coffee
. The scion is soooo much more vehicle.

I just filled up today (including four gallons in a five gallon can for my lawn mower 
)! It manually calculated out to 27.5 mpg over 330 miles (2 gallons still in the 14 gallon tank)l I've no highway miles and lots and lots of light controlled intersections. Sitting at a light idling is typical, together with top speeds of 27 to 38 mph (depending on the stretch of road). I occasionally exceed fifty, but that's only very occasionally!
Believe it or not, I also have some performance embellishments -- CAI, P&P TB, lightweight pulley, but I don't usually tickle them -- I'm very conservative on the throttle and tend to coast a lot!

yes you are right .32 is the drag coefficient per specs, I looked at other cars that had that same drag coefficient and they were much lower profile and sleeker. I find that xB coefficient hard to digest when compared to those. Not sure what wind tunnel they used. Probably the same facility that came up with the 22 city and 28 hwy.
REGARDING ETHANOL - This is the biggest rippoff in america. Ethanol production is a joke. My steaks cost more...damn it. The corn used to produce ethanol drove cattle feed prices big time. Producing Ethanol is not as green as people think. It takes lots of fertilizer, water, and energy to produce it. now it is reducing my mpgs AND making my ribeyes cost more.
THIS IS MY LAST INTERNAL COMBUSTION CAR - yes this scion is it. I will buy electric next time. I was going to hold out for later in the year for the chevy volt, but cost is too high. I will wait for the costs to stabilize in 4 years or so. Also, there will be more infrastructure, charging stations, etc. Mark my words, in a decade the majority of cars on the road will be electric.

Not complaining about my mileage, Im just glad to have a reliable vehicle that I can fit all of my art crap in :D
EDIT: I just got back from a trip....I got 29.1 mpg on the highway(AT trans). Who's complaining about going 70 on the highway??

I still love my 2011 xB (automatic), however, I am not getting the gas mileage I was expecting and am really disappointed. I am looking at both the avg mpg on the dash board as well as taking the measurement the old fashioned way. Both seem fairly close. I drive about 80% hwy with some hills and A/C. I drive about 70mph when on the hwy. I am getting 24.5 mpg consistently (measured on last 3 tanks). I know this is in the advertised range of 22 city and 28 hwy, however, I read a lot of persons where actually getting even better than what Scion advertises. I was expecting at least 26 to 27 mpg with my driving situation. My previous car (2004 Jaguar, 300 hp V
got better gas mileage on the hwy. I don't have a lead foot either. This concerns me. Is this because it is new and the engine is still tight? What are you all seeing with similar driving situation? Will it improve?

Who really thought that they were buying a fuel efficient car??? I loved the looks of it, like a chop top version of the Gen1. I saw the EPA ratings and knew right away that they were dream numbers based on the drag coefficient of the car along with the bigger displacement, but, didn't care about that. I have a Fujita CAI, and have eliminated the scuba tank, I get around 25.4 typical. I have gotten as high as 29 between Phoenix and SoCal, but that was being conservative with speed and throttle. That was amazing in my eyes. It wasn't supposed to be a fuel saver vehicle, just a youth oriented car with a balance of fuel consumption and "fun" for teens and with the Gen2 an older crowd too.

New to Scion and this site. Just purchased my 2011 xB stick shift on friday night. Two days later with moderate driving both highway and city, my tank has now decreased a little passed the halfway mark on the gauge. I also noticed the gauge decreasing significantly fast each day...all with moderate driving...did anybody else experience this? i read reviews online about the fuel economy of the car and understand it may not be the best, but its still a 4 cylinder car so i still should be able to stretch the tank for more than a week right?

BTW, if you're not happy with the mpg now, then don't even think about getting larger/wider wheels & tires that will weigh more & crush your mileage even more... just saying.

agreed^^^ what i do is roughly 286-300 a tank. and yes i fill up once a week or so. and thats a combo of driving safe and some flooring going on. this is not a fuel efficient car or some big gas saver. its a car. drive it!!!
