real world mpg frs/brz
 

Curious as to the real world driving mpg that people will be getting. Please give an estimate of how much city/highway driving made up your numbers.

Go check out Pekingduck's thread. He said somewhere around 30, IIRC>

Filled up first time today.. manual FR-S got 29.6 MPG average
 

So I filled up after 285 miles today first time. Averaged 29.6 MPG which is not bad at all considering most was mixed light city and highway driving together. I'm keeping it below 4k RPM for break-in which probably has a lot to do with it. I'm not hyper-miling in any sense.

The mileage exceeded my expectations.

Calculation method was simply miles driven divided by gas I put in so it could be the case that the dealer topped it off to start with which mean s my number could be high. Avg MPG on onboard computer shows 29.3 average MPG.

I'm still on the first tank of gas (will need to fill up tomorrow) and the car says I'm averaging 31.0 mpg. I'm also keeping it below 4K, but not hypermiling or anything like that either.

Oh, and it definitely exceeds my expectations as well.

That's awesome, MT for you guys? I highly doubt even once the car is broken in I'll be taking it much higher than 4k RPMs on a daily basis, so if I can get around 30 on a consistent basis that is better than expected. Hoping for closer to 35 on road trips while cruising at highway speeds.

My Impreza is rated at 26 highway and consistently gets around 29 on longer road trips fwiw.

I can’t seem to get it down to less than 10 mpg for any length of time but I will keep trying.

30 MPG avg is totally awesome in this car. Now if you hyper mile and take a trip from SA to Dallas, you might avg about 40 MPG!

Idle at 7000. That should help.

So for people posting their numbers, I'd really like to know what transmission you're on. And thanks!

I have a manual.

Per title in my post, it's a manual.

Until you hit Austin! That is, unless you take the loop around it.

Can the manual drivers tell us what the cruising rpm is at 70mph? I'm still torn between getting the auto/manual as it will be my daily driver and the extra mpg wouldn't hurt. I know the auto cruises at 74mph at 2500rpm which is super nice!

Pretty sure I read it was around 3k.

2500 RPM at 74? Damn, that would be nice. Here's from a previous post I made:

"With manual transmission : indicated speed of 60mph is 2600 RPM, 70mph is 3000 RPM, and 80mph is 3450 RPM. That is better than I hoped in that I'm one of those guys that likes an overdrive 6th gear for good mileage and quiet interior at highway speed."

If the auto is doing 2500 RPM at 74 then I think I will consider dropping in the 3.73 rear diff gearing. Sure, it will make all the gears taller but I can live with that. I don't think it will get me to 2500 RPM at 74, probably something more like 2650 RPM at 70 mph but it's closer.

I do 50/50 city highway split and I got 19 on the first tank, and about 24 on the second tank. A bit more highway on the second tank and a bit less hooning too.

wow, definitely exceeded my expectations of "real life" as well. Be interesting to see what it does when we start modding/tuning.

I saw close to 300mi on 1st tank, mpg was showing 26.9 avg :)

subscribed, im really liking these numbers reachin up to the 30mpg range

this will likely be the deciding factor that seals the deal for the BRZ for me, most competitors im shopping get ~20mpg

in my experience so far is that real life mpg for any car isn't far off or exactly how it is rated (assumming normal driving)

the 2-3 examples up top are exactly at rated mpg

with that being said, if your car is rated 35mpg on the highway, doesnt matter how you drive or what you do, you CAN NOT get 45 mph on the highway.

speaking from experience with the cars iv driven and read on what ppl get.

What size tank are we looking at for this car?

All depends on how you drive and where you drive. Lots of highway miles? Much easier to hit EPA numbers for almost every car. Lots of city driving with short trips? Much harder.

And of course your driving style. Keep in mind some of these guys are babying their cars. Once you start winding the engine towards redline and higher RPM's you are not going to get EPA numbers most likely.

Consumer Reports has done extensive testing with city vs highway and the consensus is most cars can meet or beat the EPA numbers on the highway, but it is hard to achieve EPA in the city.

I'm anxious to see what I can get with the BRZ. My S4 is rated at 18-27mpg. I averaged 30.1mpg both ways on a recent 80mi. trip; on shorter trips I can get about 25mpg avg. My long-term average over 8,100 miles is 22.1mpg, 1.1mpg better than the EPA states.

However when I can't keep my foot out of the supercharger I'm hovering around 20mpg ;) Not bad for 330awhp, though!

I think you're wrong about that. Some "hypermilers" can get well over 10 mpg more than rated.

My 1998 Honda Civic has 208k miles on it and gets 40 to 42 mpg on the highway.. EPA rating is 34. I don't even try to eek out every mpg.. I just drive it normal.

I don't know about the FRS/BRZ because I don't have one yet.. but I wouldn't be surprised to hear people getting close to 40 mpg if they really work at it.

^^ well those hypermiles are an exception. there's always exception.

but for us normal people. what you see on paper is pretty much what you get IF you dont try to race every car you see.

lol

You can easily get more than EPA numbers. My car is rated 31 highway, and that is the mileage I get if I cruise around 75-80. But if I am on a roadtrip I cruise control at ~63 and get over 35.

You can look up the actual test cycle and how much load they put on the engine and stuff. You will see if you have a light foot you can exceed those numbers no problem.

The 2008 ratings are completely unrealistic. I got the pre-2008 numbers no problem. And when I tried, I exceeded them. :iono: I'm not special, half of it is just paying attention.

I think it's closer to 2800RPM at 70mph. The OD in the AT is over 20% taller.

I would do the taller final drive swap and then sell the stock 4.1 gears. :)

Not bad. BTW, the stock gauges lie. Speedometers always read several percentage points too high. :D

Exactly. 90% of my driving is <50mph. There's no much you can do about long stretches of interstate(without going into advanced tips) but low speed is where the best MPG can be found. ;)

:clap: Were you even pushing it though?

this + infinite. Damn austin to hell.

You guys all live on flat plains though. I assume I will get closer to EPA estimates considering how hilly it is here.

6AT FR-S first tank fuel economy
 

Filled up the first time this morning. Note that I do NOT know if this first tank was regular or premium. I was there when the dealer filled it up, but frankly didn't think to check. Since there is only one marking on the inside of the fuel cap cover that says Premium Fuel Only, I'm guessing it was Regular.

MPG over 308 miles was 29.38, mixed city/hwy, but probably a 65/35 split. Also included probably 10 to 15 minutes of total time at pure idle (showing people the car, listening to the engine, etc).

My city driving is a lot of stop and go, many stoplights.

My last DD had a 289K lifetime rating of 17.5MPG and used regular fuel. Based on that, on this one tank of gas, I've saved $20.77 over my last DD even with the price difference in fuel!

I'm a little disappointed the car does not have an Avg Speed display. My 2001 Astro (last DD) had that as well as Fuel Remaining. Avg. Speed over 289K miles was 35.7 on it.

Semi-Automatic FRS, Production Model
10 days of ownership @ 960 miles old.
I am at 26 City/ 32 Freeway, according to the on-board display. :D

I've had 2 tanks of gas with around 26 mpg. Most of it because of stupid 405 traffic in Seattle.

this is why i am interested in the responses to threads like this. i find EPA numbers much less useful than what people are getting in real mixed driving. and yes a persons driving style impacts those results greatly, which is why i am looking more at the averages and trends of peoples responses. i would say keeping it below 4k rpm (which i believe is break in rule) reflects average driving, true it wont factor in the few on ramp redlines that are inevitable later on, but as far as a whole tank average they will end up being close, or at least still more indicative than epa numbers.

I finally filled up this afternoon. I did 348 miles on 11.08 gallons, so 31.4 mpg. I'll keep track of it during the coming weeks to verify it. Also, once I finish the break-in period I'm sure it will go down some.

From the sounds of it, it won't change too much, or might even be better than my current car. My mazda 626 gets about 24.5mpg on a regular basis. I always refill it at a quarter tank, which is roughly 300 miles driven. So this is good to know, especially with the premium gas.

Tach and MPG readings at highway speeds
 

If you want to know about tach and MPG readings at highway speeds I performed this little experiment yesterday at 55/60/70 MPH as documented on my Owners Log. Of course, YMMV and all that sort of thing.

You guys ever use www.fuelly.com? I'd suggest you track your fill ups there. It makes it a lot easier for others to see what you're getting over a range of time as well as fuel costs and other metrics.

Wow, there is such a huge difference between MT and AT. Thanks much for this info.

what size tank is in this car

Gentlemen, it is in the sticky posts; 2013 FR-S Product Technical Info and Specs (from Las Vegas press event).
