I think I've beaten all of yall, I average get 220-240 when the light comes on. 70% city, 30% highway. The best I've gotten is 300 on the highway at 75mph. Im also on 17s and stock everything else. No extra added weight.

 

I just drove my xA from Atlanta to San Antonio and back on 150$ gas. I got 32mpg most of the time. Maybe its areo?

 

hehe the one with 255 HP? 0-60 in ~7 sec? 3500+ lbs? ;) it is frecken expensive tho... ;P

 

It's mostly about acceleration and top speeds. The drag is exponentially greater at speeds above 55. Sure, I've had other cars that got better mileage, but I didn't have a choice of shall I accel fast or slow... slow was the only option. I used to have to drop back and get a running start for passes.

Also, You WILL NEVER get 11.9 gallons of gas in your tank, even if you run out of gas. Figuring out your gas mileage without using the exact miles and gallons used is far from accurate.

Some states like CA right now are still on the winter blend of gas that has more oxygenating agents in it. I've noticed a 2-3 mpg drop just from that alone. Hopefully the'll be going off it soon.

I currently get about 26 mpg consistently, was getting 28-29 last fall. I'm not complaining either, considering the speeds i drive.

Don't forget wearther factors... Does it rain alot? Lots of wind this time of year? Things like that will affect your mpg...

Also, putting it into perspective, Considering a yearly avg of 12,000 miles a year, the difference between 25mpg-30mpg-35 mpg is about 60 gallons per step up difference. At $2.50 a gallon, that's a $150 dollar difference in cost over 12K miles Barely over 10 bucks a month. Personally, the time I save is worth the extra gas I burn. Is it to you?

 

I only have a little over 900 miles on my XB and have been getting around 30 mpg. I thought i would get a little better, but 30 aint bad. My mom has a Civic Hybrid and that gets around 35 mpg. So 5 less than a hybrid aint bad. The gas mileage has a lot to do where you get your gas at to. Also they change the additives of gas from summer to winter depending on where you live so that has a lot to do with it to.

 

I have filled up twice now and it has been 31 and 32 mpg. I calculated it by the number of gallons I pumped into the tank and the mileage. It is so much better than my 4runner which got 14 mpg. The fact that you only have to fill it up with 9 gallons are so is awesome!!

 

I live in Pittsburgh PA (hills, hills, and more hills) I drive about 70% on the high way. I get around 36.6 mpg. I shift under 3000 rpm and drive 65 and under.

 

Terrain flat or hilly? I'm in a pancake state. I find this 1.5L engine has more than ample HP for my interests.

In Japan where gasoline is pricier by far and HP is taxed by displacement (yes?), the standard engine is 1.3L

Displacement means a lot to fuel milage because an IC engine does not run so efficently below or above it's peak torque rpm (volumetric efficiency, I mean)

If/when fuel here in the USA goes above $3 per gallon perhaps we'll be seeing a 1.3L engine. In fact, if that were available I would've gotten it.

Even underpowered, a car can be fun- more of a challenge to -work it right- when conditions demand that. Driving a Model T in traffic for many years taught me that go-fast may be a thrill, but so, too, is thrashing an econocar. Like the old beetles of 1.2L capacity and very lower HP and torque than we can get from a modern engine with today's super technology optimizing engine performance. The underpowered car can be fun to drive.

Key point: displacement in excess of what is needed for the median load is a full time waste of fuel. If a maker could make an engine cut back to say, 12HP displacement "size" when cruising level terrain at 55, then -that- would make a super mpg -under that condition-

My old Subaru SVX had a 3L 230HP engine, but was so aero that only an estimated 8HP was needed/developed cruising at 60mph (so i read one time)

I really don't know much correct along these lines... so will appreciate getting the record set straight if you know better.

 

I average between 28 and 30. the best so far was 32 mpg. That was after the CAI install.

 

Hybrid cars are another way to attempt this very thing, ie. keeping the engine at as near peak efficiency as they can.

Dodge also has a feature on some of their V-8s that will shut down 4 cylinders when not needed, like at freeway cruising. It doesn't seem like it'd be worth the extra technology on a 4 banger that is already pretty economical...

 

The mileage is somewhat of a deceptive matter. I have driven a little over thrity miles after the [gas] light came on. There must be about 2 gallons left when it first comes on or something. For those getting about 270 miles per tank, you may actually be better off than you think depending on how you are judging fuel consumption.

 

no offense, but how are you driving? i have an xa as well w/only 2450 on it and get about 35-37 mpg. i drive about 30 miles to work and 30 miles back, but then again, i drive about 60-65 mph.

 

But isn't the Jetta gas tank like 14-15 gallons?

 

Hey, thanks. That's very interesting and jibes pretty well with calculated data I see in a 1922 book, "Everyman's Guide to Motor Efficiency"

Model T was limited to about 50mph (much variation). About 20 HP developed.

 

I think that you should all have looked at the economy before you bought the car. If 27+ is not enough for you then you should have bought a Honda Insight or a Toyota Prius. MPG 50+ on both! Very few people bought Scions because of the gas mileage. Sure it is a plus, but I know I was not thinking, "Wow, it gets 30 MPG!!! Rock on!"

 

Part of the reason i got the xb was the mpg. I think I get around 30, but i have only filled up the car 3 times since i bought it 3 weeks ago this saturday. I think its a very important thing to consider when buying a new car. Gas prices in so cali is around $2.50 a gallon. Thats not going down anytime soon, in fact it should go to $3.00 this summer. If you dont think about mileage, you might as well be like all the other a-holes driving there pos Hummers around getting 8 mpg while looking like total shmucks. God i hate those cars....

 

Well, the milage is a big, big plus esp. as fuel prices rise

we don't like to feed oilmen of Texas nor other places.
more importantly, the CO2, I think... that is the one un-fixable bad thing about hydrocarbon burning.

but not to de-track this thread! Just say: if we drive reasonably we get great milage. If we drive for gusto, then we still get better milage than from our fat, old cars. And don't pay through the nose for the pleasure.

Gasoline won't ever run out. Dollars might, though. Predict, as you must too, that our boxes will hold their resale value relatively -excellently-, even after higher-tech cars come on the market: the slew of micro cars and hybrids which -will for sure come along before long-

I want a Will Cypha for a second car!

 

hmm thats interesting

 

I don't have exact figures and won't pretend to. But, when I take my xB from Tucson to Phoenix I used to drive 80-90 mph. Considering wind resistance I'm sure you can imagine that my 90 mile drive consumed more than enough gas. Well recently I purchased a Kawasaki Ninja 250 (that get's 60-70 mpg!) and followed my friend back from Phoenix while he kept the pace at 60-65 mph all the way back to Tucson. It may have taken longer to reach my destination, but Oh My God was there a HUGE difference in the mpg!!! I had over 1/4 of a tank left after my 90 mile commute. So every time I get onto the highway, I have been keeping the speed at or around 60-65, and have been happy with my mpg ever since.

As a side not, the Ninja 250 can attain better gas mileage than the Toyota Prius!!
