I wonder what the MPG difference is between a 250 lb male and 100 lb female driving the same car.

Also the 0-60 time lol

If found the Focus ST vs Fiesta ST interesting, 24 vs 31 mpg. That's the 500 lb weight difference in action I guess.
It's more than the weight difference it is also displacement and power. The Fiesta ST has a smaller more efficient engine and makes less power.

And yeah I am with you, a 3+ mpg savings at the pump adds up. Especially once gas creeps back up to $4-5 per gallon.

I hate gas mileage threads...

The trip computer should not be used AT all for results. The only valid results should be from mathematically calculating your average after you burn through a tank of gas. The computer is just another variable added to the 953 other variables that can cause me to get 15mpg on week, and 29 the next week.

It't not even worth debating, as this is only the one millionth time a gas mileage thread has popped up on NASIOC...

Why is this thread useless if people are calculating by hand (like most people in this thread)?

Like i said before. Too many variables. And most people are just reading off of their mpg display on the dash.

First tank in my 14 WRX hatch was 16.5mpg. I am averaging 20.4 now.

If I can average 23-24mpg with the 15 I will be happy. I averaged 26.5 in my BRZ.

First fill-up, drove ~20 miles home and averaged that. I don't trust the MFA display is worth a damn but I probably scored ~30+.

I was driving 90% highway going 55-65. The car seems to drastically drop MPG's once you cruise past 62mph or so on flat terrain. Sweet spot is definitely the 45-60mph range of cruising.

Wayyyy to early to make any determination on MPG's but this is DEFINITELY much better than my Bugeye when it was stock/stage2/now. The biggest problem is keeping off boost & driving like a lame-o isn't exactly easy but I'm used to hyper-miling my TDI to hit 50+ so applying the same driving style to the WRX seems to work better than I was expecting.

To be determined......

We should be seeing high 20's on these mixed. Granted the FA20 in the BRZ is a bit different, but we see high 20's on the supercharged and turbo'd models mixed when they are driven with some regard for mileage and not thrashed. Non turbo they cruise at 35 and mixed around 29-30. AWD will penalize 2-3 or so, but the turbo should actually help with efficiency a bit in the medium load areas.

Disagree. The car weighs nearly 400lbs more, has wider wheels and stickier tires, and more frontal area in addition to all that AWD driveline drag. You also seem to be forgetting one very important thing, boost doesn't come free. Cram more air in the motor and it's met with more fuel. Turbos allow smaller motors to behave like bigger motors. Add boost and they consume the same amount of fuel as a bigger comparable motor.

I think many of you are grossly overestimating the mpg improvements with this slightly more efficient motor. I think Celery is the only realist in this thread.

well I've seen my mpg display maintain 36mpg rather easily, just haven't had a chance to do it for an entire tank to see what it really is.

After a week of owning a CVT, my MPG on first refill was 25.5mpg in mixed driving and playing with all the CVT options - lot of fun actually. BTW, the electronic readout was 28.5 at fill up - 3 mpg off.

For reference, I averaged 21.8 in my 2002 manual HB, and 23.0 in my 2007 manual HB in the same type driving conditions, so I am quite happy with 25.5. I expect it to improve to some extent; I expect 28-29 in pure Highway mode based on adjusted electronic readout data.

I have pretty much settled on "S+" for normal driving, "I" for highway cruising as it drops the RPM dramatically.

I could pull pretty decent numbers on my 2010 I could probably do better on the 15' I would surmise.

I switched from a 13 mpg RX8 so anything above 20 makes me happy.

I can get my 2012 to show 33-37mpg if I fill up and then proceed to do steady state 45-65mph driving with little to no stopping and no hills/minimal wind. The highest I've seen driving all highway (flat, little wind) with little stopping and no cold starts was 29.6mpg (computer said 30.2mpg). During my daily grind (50/50 driving, highway ~70mph, lots of Kansas 15-20+mph wind, hilly areas) I see around 22-23mpg depending on the time of year. If I lived somewhere like Florida where it's warm, extremely flat, and with little wind, the car would be getting at least 2mpg more.

My point being, these new cars will see better mpgs than the prior gen and they should BUT they're not seeing a massive improvement over the last gen.

never got my 2011 to show over 27 or 28 for any real trip. I could get it to show 33 resetting it on the fly and barely moving my foot, the new car will stay in the mid 30s even with some stopping and hills. the 15's average mpg is 23.3 which includes a crappy 20.5mpg first tank. I tracked something like 114 fill ups in the 2011 and it only exceeded 23.3 13 or 14 times. I beat my best tank in the 2011 (26.4) on my 2nd tank in the 15 (26.8) and I haven't done a highway tank yet. The 11 used to routinely get 18-20 mpg in around town driving.

3rd fill up, 23.8mpg hand calculated. Used the exact same pump for the fill up. Display said 25.2. 70/30 city/hwy miles. First tank was 30/70 city/hwy miles and it averaged around 28 mpgs if I remember right.

Getting 25.5 now after 1200+ miles of break in and running the lightweight optional sport package alloys. This is in a 6M base.
