What fuel economy numbers are you getting?
 

I've seen the fuelly listing on many sig's, but they vary wildly. Personally I'm getting around 32mpg in my FR-S without trying very hard. Admittedly it's not very bad city driving and the occasional expressway trip. I'm just curious as to how others drive. I really think a lot of it has to do with driving habits from my previous car: hybrid with a 6MT.

I UNDERSTAND CONDITIONS MAY VARY

I have only had my car a few weeks, but I am getting about 24mpg on mostly city driving (I would say 80% city 20% highway). Have not run the A/C much either so I am hoping this gets better and not worse over time, but I am pretty much at the EPA estimate so I cannot complain. Car is a manual BRZ Limited.

Generally i would say the observations suggest a car whose FE is very dependent on how and where you drive it. City driving with contribute immensely to poorer results, especially the longer you use the very high 1rst gear.

Highway FE can be amazingly good, especially in the AT.

38 mpg highway cruise set at 65 mph sustained. windows cracked, no ac, just the "blower"

26-27 city occasionally acting like an ass

I'm getting 32mpg average . I have a scan gauge.. manual transmission

Poll like this is biased due to driving conditions and hills. Not everyone is going to produce the same results.

If I drove to work 20 miles each day on the interstate only, I'd report 32-35 mpg with no traffic.

Realistically with traffic and the city driving I do, I'm averaging what my Fuelly states, 27.7.

Use Fuelly if you want accurate results based on your odometer. Our car is averaging 27 MPG on that site.

Entirely dependent on driving conditions.

Straight city I'd average around 24-26 mpg, straight highway would be about 32-36 mpg, highway commute is about 29-31 mpg, reality is somewhere in the middle depending on what I do that week. Stopped paying attention about two months ago when my phone died and I lost the mileage records on it.

Should state whether you have MT or AT.

I've been getting about 29mpg. abouy 50/50 highway city. AC about 65% of the time. MT.

Oh about 25 city, 30 highway - manual transmission.

Your poll doesn't account for wider, stickier tires. :) I was getting 27-28 mpg, but I put on new wheels and tires last week. My mpg has been dropping since the install and I'm not sure where it'll settle.

At essentially 22MPG, I feel I probably have one of the lowest actual MPGs on these forums (using Fuelly and being very exact with my data - usually to at least two decimals for gallons pumped). I do live in LA and my commute to and from work is only 4 miles through traffic. Plus I did go with aftermarket wheels/tires (225/40/18) but the rest of the car is bone-stock. I really don't think I have that heavy of a foot. Maybe its the cheap Costco 91 gas I'm putting into my car. The best MPG I ever got (25MPG) was on my first tank when I was still breaking in the car and was keeping things under 4K RPM.

You aren't alone. I think I get around the low 20s as well. I have around a 30mi round trip commute and I can see the needle dropping. It's a lot of random stop and go traffic with lights in the mix. I have yet to have a perfect day where I hit all the green lights.

I'm seeing a ton of variables that would make the poll a bit much, but so far we have:
(1) Hills / Elevation
(2) Aftermarket parts
(3) Octane level of fuel
(4) *why not* Zoidberg

I get about 32 averaged out in a tank. My commute to work is 0.8 miles so typically I do not drive and this keeps it higher, when I actually drive to work my average drops to 25-26.
MT

Poll comment doesnt work for my mpg of 29 avg.. Mostly city/country roads and some hwy.. But pushing way past 4k rpms when conditions allow..

I didn't vote in the poll because my numbers don't match the descriptions you provided:bellyroll:

Worst tank I've gotten is 27 mpg around town. Best on the highway I've gotten is 35 mpg. On Fuelly I'm averaging around 29.5 mpg. Manual transmission. I only use 93 octane fuel from BP, Exxon or Shell. I've noticed that using the AC lowers by efficiency by around 2 mpg.

And I thrash my car. Redline (or close to it) every day. 6000-6500 rpm is hit with a frequency to high to measure on a daily basis.:burnrubber:

I've been getting around 31-32, MT, mostly highway, basically no stop and go. I always fill up with 93. No complaints here.

And I am not sure about the Subaru/Toyota average MPG display in the car, but I have found these to be inaccurate in about every car I have driven (sometimes as much as 2-3mpg and in many cases it varied on the car (same make/model, different vehicle). Some people were off by 1mpg and others off by as much as 3mpg). So that could also be a factor as well if people are using it to report their numbers.

Hmm, this is a very good question. I use the in-car MPG... habit from my hybrid (not Toyota).
I've got a road trip tonight: excellent time to confirm highway F/E.

Only problem with the in-car MPG is it counts for idle time in traffic and at lights. Mine has been off about 1-1.5 MPG when I do the numbers on a fuel up in Fuelly and I'm pretty sure it is all due to the idle time.

This instrument (at least in my car) is optimistic by 2-3 mpg. It doesn't account for time when you're in traffic idling. Thus (in my experience) it is more accurate if the driving is all highway and less accurate if it's all city.

If I was driving in LA traffic I would be happy with 22 mpg in this car.

I've never seen so many people mash the gas and stomp the brake just to close a car length, if you're used to it it seems normal but man is it weird to an outsider, the desperation for 10 feet just emanates off of every prius and suburban.

Combustion engines are most efficient at constant speed and constant load, stop and go is death to fuel economy which is why hybrids exist.

What you're describing sounds more like the mentality of a New Yorker. I don't speed up just to block others from merging into my lane nor do accelerate knowing there's a red light ahead that I will need to be braking at. There are just a lot of cars in LA and we do have stop-n-go traffic, especially during rush hours.

<off topic rant>I'm just pissed off when people don't understand about basic flow of traffic. On the freeway if you're in the fast lane, you have an obligation to essentially be the fastest car in the area. If you're not, you should let the guy behind you pass you on the left (regardless of how fast you think you're going). I feel like with traffic on the surface streets most everyone basically knows what they're doing and are just trying to get to their location as fast as they can (there are just too many cars on the road).</off topic rant>

Mine doesn't show in mpg. LOL it is shown in metric. I am averaging 9.5 liters per 100km. But the car is not broken in yet so the mileage may be higher than normal.

18.6 shows up on my dash for some reason. going to use an app to see if it matches up.

yeaah my vortech and visconti tune along with the beautiful sound of the ark test pipe and catback is just making me boost . plus i love the sound of my bypass haha. people trip when they see a frs take off and hear "pshhh"

31.. i do 5/6 k shift sometimes :burnrubber::D thats what i love about this car you can drive it 80/100% and still get great gas mpg:thumbup:

M/t, 32.. 50/50

Average 20-21 mpg every fill up for nearly a year with my normal driving habits, if I take it easy I can get 24 mpg. Long distance cruising on the highway @ 75-80 mph netting 30-31 mpg is easy...and repeatable.

Daily driving environment:
93 octane, sea level, hot and humid (90+ degrees/80+% humidity) for nearly half the year - and most hot and humid June through August. Daily chance of afternoon heat showers as well....which blows the humidity to basically 100% for the rest of the afternoon...

Relevant car setup: Traction completely off (hold button for ~ 5 seconds), A/C on, set to second coolest setting, Fan on second speed, lightweight 17x7.5 Enkei wheels (17 lbs) with the stock Michelins, 5W-30 engine oil (Redline Synthetic) - changed every 4-5k miles, aftermarket exhaust ("Y" catback design that gets rid of the stock muffer configuration), Perrin foam drop in air filter.

Driving habits:
Shift @ up to 3k and keep steady rpms around 2k before car warmed up. Once car is warmed up, rev to shift indicator (set at 7k) before up shifting, when slowing down, downshift through the gears usually stopping at 3rd gear when coming to a stop and clutch in/neutral when stopping and clutch in/1st when about ready to go. When making right turns at intersections onto a main street, maximum acceleration through the turn - just chirping the tires for maximum rotation speed . When approaching some nice s-bend feed road sections leading to overpass or other nice "curvy" sections - down shift and accelerate from about 4-5k rpm. I don't play around if I need to pass in a hurry, downshift to whatever gear will get me to 5k rpm and accelerate 100% (and shift if necessary) until pass completed, then let off, coasting down and getting back over in the lane. For easy passing on the local interstate (which is a majority of the time on it, but only about 30% of my weekly driving time) I just roll on the gas in current gear, usually waiting for going downhill on overpasses to apply throttle if the pass can be timed easily for such.

9.7 L / 100km whatever that is in mpg

Mostly hwy driving but i am rarely aiming for fuel efficiency...

I'm averaging about 30-35mpg depending on the weather. Pretty much driving as hard as I feel like, especially in the turns. I was surprised bc the MT is only rated at 30mpg highway. Most of my driving is on rural roads, with 55mph speed limits.

Im getting 30mpg combined with 70% city driving.

I get about 26-27 in a mix of MT driving. The FR-S seems exquisitely sensitive to rpm changes. Pure highway mpg, where the revs change very little, is amazing - close to 40mpg, but back road driving (even without stops) drops to 32mpg. Add in even a little suburban or city driving and it drops to 26mpg. My observation of heavy-footed drivers is that they still get in the low 20's most of the time. So overall, the mpg is pretty good - just a little disappointing on the winding back roads going 40-50 mph (where previous cars of mine got the highest mpg). It is clear to me that the best mpg is achieved in really boring Interstate driving going 60-65mph.

26mpg here. heavvvvy foot lol. car has been tracked 2 events, many times on the track on each event haha. 11.4k miles. manual transmission. stock.

Is this perhaps due to the tall top cruising gear?

29-30 mpg with my foot in the floor most of the time.

I don't think so. Except in the AT version.

I kind of question the folks who say they're actually getting 30-35mpg (and not just because I'm getting a crappy 22.5mpg).

For the MT (because I believe the majority of owners went with the MT), the government EPA estimate says 22mpg city and 30mpg highway with combined being about 25mpg.

Unless you live in rural America and most all your driving is in 55-65mph range on the highway, it is hard for me to believe you can average >30 mpg over the life of this car.

Are you calculating using your miles driven in your trip meter and dividing that by the # of gallons pumped or are you just relying on the car computer to tell you?

im using what shows up on the dash when you press the display button which for some reason is still shwoing 18.6 despite how "economic" i am trying to drive lol. When I switch to the avg mode however, its like in the 40s on highways with steady RPMs, and around mid 20s on city. One good thing coming out of all of this though is I am learning throttle control with the car, something I didn't really care much for when I was driving automatic. It's a learners car like the original 86.
