Look at the acceleration differences - assuming the info is correct, It must be geared completely different

 

Got 32 and change on my last fill up and i was driving pretty hard. Using the shifters alot too. Still haven't broke 35 while driving conservative yet

 

u're right, also japans weighs 200+lbs lighter.....would be nice to really find out what makes the extra 10 mpg......

 

put a 1.3L in there and drive 5mph

 

it was already stated that it was the 1.5L that got the 48mpg.

I would attribute it to the lighter chassis and different gearing of the car. Simple things can go a long way!

 

First tank of gas I got about 280 miles to the tank before the light came on but I tried to use the paddle shifters to shift at 2500 and keep it below vtec.

 

how bout u push down the road at 5mph, ill get better mpg there.... seriously, 10 more mpg would be heaven.....would be nice to verify or find out what makes it....again asuming the spec's are right.....i know it can be done, i had a 90 civic that gave me 43 mpg....

 

Yeah that sounds about right I think mine was 9.02 at 280

 

You can try to tailgate cars so the vacuum will help drag you along and save gas

The spec sheet lists the "Principal fuel economy improvement measure" as "Variable valve timing/electromotive power steering/automatic non-stage transmission (CVT)"

The Japanaese Fit 1.5A Front Wheel with CVT transmission gets the 48 mpg, not the comparable 1.5S version. See the translated Japaneese specifications page. It seems like FitFreak.net's front page seem to mix and match specs. I haven't checked out Aus/Asian sites yet.

Edit: After looking at the Australian and New Zealand website, the Fuel economy values are only in a single combined number, which was around 39 MPG.

 

I have to wonder if those of you who have automatics might have better results if you manually select 4th gear (or less) when climbing even modest hills with your cars.

Keep in mind that the gearing in 5th with the automatics is pretty tall for a 1.5 L engine. Based on the 5th gear and final drive ratios, I've calculated that automatic should only be turning around 2,162 rpm @ 60 mph (vs 2,811 for those with manual transmissions). That's a significant difference! My guess is that Fits with manual transmissions probably don't struggle nearly as much when climbing most modest grades in top gear.

The automatics tall gearing is an advantage when cruising on level highways, but staying in 5th when climbing hills must really make these small engines struggle. My parents used to own a 1st generation Toyota Camry ('85) that also was equipped with an automatic transmission with an unusually tall top gear for a 4-cylinder sedan weighing over 3K pounds and having just under 100 hp. This Camry got great mileage on level highways and was very quiet. However, it was a weak-kneed dog anytime you encountered even a modest hill-especially if you were carrying a car load of passengers.

 

For those without auto tranny, this car drops a gear with VERY modest grades. It is geared very tall in 5th, and revs a little without a total downshift on initial climb and then totally into 4th with more than a short hill.

 

As the japanese fit is not in the US, I would assume that the 48 is imperial gallons, and, thus, is approximately equal to 40 mpg. This seems reasonable as it weighs 200 lbs less; however, I am only speculating.

 

1 Imperial Gallon = 1.2 US Gallons.

Slightly different weights, slightly different testing procedures (eg Canadian ratings are 29/40 MPG US Gallon, despite being the exact same car)

 

CVT transmission?

The trend I see is that the AT Sport gets bad gas mileage, primarily in te city. I am almost always in traffic (Orlando, FL) and I get 26MPG.

It's ok, my old car was a Grand Marquis and I was paying about $45 for a fill-up (Every 4-5 days) and now I pay about $28, so I'm happy.

Can you guys do me a huge favor? Next time you pump gas, when closing the gascap, once it hits clicking point, can you push down on the cap and give it another 1" turn? I want to see if we're losing any compression. On my locking gas cap it seems to click pretty early and Im afraid theres not a proper seal. I noticed my MPG increased by 2 MPG when I did that.

 

Hey I am in Orlando too. I usually drive 408. Yesterday, I hit 315 miles on the tank. I filled the car up to the rim and the total was 7.95 gallons.

 

omfg - did he say.................NAW, COULDN'T BE.


IF THE CAP IS LOOSE, YOU WILL GET A ''CHECK FUEL CAP MESSAGE''

Ya'll can ignore the last post on the previous page.

 

Hmmm. I drive on the city streets mostly. John Young, Hiawassee, Silver Star. If I'm on the highway (I4, 528), I'm on it during peak travel times. I travel all over this crazy city. From Crime Hills to Hunters Creek and Winter Garden. Too Many traffic lights.

Nice mileage you got there.
