lol - my highway mileage blows. From from Florida to North Carolina today in my Scion xB, and here are my fuel consumption averages:

First Refill - 28.45mpg
Second Refil - 27.28mpg
Third refill - 25.30mpg

Hell - I average above 30mpg in 100% city traffic - I guess doing a constant 80mph really takes a toll on the small engine. That - and the whole un-aerodynamic thing, but still! I guess I shoudl probably figure in load too - I had three passengers, and luggage for the trip - A/C on too.

I have pinpointed the reason for the VERY crappy mileage on the third refill - this probably doesn't help <----link to click

 

I have experienced that before too. I have burned about a quarter of a tank on small trips, but I was going about 108 mph(lol). I dont know if it has a governor or what it's top speed is, but I know it was going to go much faster.

 

what is that reason? Hilly interstate in that area?

Weight does not much affect fuel milage at steady highway speeds.. on flat grades.

Is that what you meant?

 

I typically don't go over 65. I've taken my box on trips hundreds of miles long and the mileage never dips below 34. I experimented with driving at a higher speed on one trip and the mpg dropped to 28.

 

Just drove from Orlando to N GA. Got 32mpg the first leg and 34 the last. Avg speed 62.4 mph. Only stopped twice for food and gas.

300 miles i had two fill up 1 at starting point 2. half way there so i need 1 tank and half. reason for that.. driving at 80-105 kills it.
on the way back i filled up once and thats all needed.. speed 55-60 due to the scenic road i took.

It's a photo of his speedo reading 106 MPH

thanks for that!

z0om. Where is Scotty?

Scotty: I tell ye, Captain- that red glow of the dilithium crystal viewport prove she's stretchin' the space time continuum near to the breaking point! I doona know how long this ship can last!

who's driving without a seatbelt at warp factor 10.6?

 

I've read a road test that says the top speed of an xB is 109 mph. I don't know if that is governed or not.

 

that's such a great picture, rbloedow

here- make it in clicknail view; is ok?

How'd you do this? unbuckle and snap the picture yourself? Whatever, it's muy rapido machismo

 

ennnnnnnnnnnnnnnnn wrong. i've gotten mine to an indicated 125 mph. on stock tires. so diameter and gauges are not off.

 

i killed 3/4 of my tank going to lancaster and back to the valley i was doing anywhere from 65 to 109 mph most of the 109 was going down hill

 

Yeah, I didn't buy my box to go fast either, but it just happens to be more convnient when I am in a rush.

 

OK! Good for D'hotbox guy. Let's figure out just what and why...

=Headwinds count for direct additions/subtractions to top end
=so does a slight grade that we might not even notice (remember, bicyclists
=tire diameter matters hugely

why izzat? you guys know-- use the tire calulator program and look at the torque and HP curves of xB engine.

By golly gosh darn, hotbox5 you are not long winded, as I sure am, but you do put up the pith of the truth every time. And I try, poorly, to put the flesh all back on the bones

 

38.5 mpg consistently. Then again, various police depts in NY state tell me I'm not allowed to go over the posted limit. After losing my license for a couple/three months (7-8 years after the fact) I finally got the point. But then look at the $ I'm saving = less fill ups and less fines.
My new hobby......trying to get the stock xB over 40mpg.
ThanksMuch

i was told at the dealer when checking out the xB that it tops out at about 110mph. 125 seems kind of high. When size rims are you running and all speedometers get more and more in accurate when going at higher and higher speeds.

 

stock tires and wheels. and at the most that the speedo would be off is 4mph.

 

... anything over 3k rpms on highway.. simply kills the mpg....

I did a similar run from miami to macon, ga.. on the way up i was going 80-90... my car had horrible mileage (24 mpg)... on the way back i was steady 70-75 and got well over 35mpg....

 

3k is only 60 mph. lol i dont care how much gas it saves i'm not going to get run over and take an insanely longer time to drive around.
