Real world gas mileage on the 2017s - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

brillo · 01-06-2017, 02:50 PM

I routinely beat the EPA estimates for our car (both city/hwy) with my 2013 86.

I'm curious if the change in final drive really hurts the economy as much as advertised. anyone have any real world data or experience yet?

17 city and 20 highway roughly for me on average on stock tune...

driftartist · 01-06-2017, 03:15 PM

I am also joking

In the summer I get 30 city 38 highway. Right now it's about 25 city 33 highway because cold and winter gas.

I get around 28 combined with an automatic. Quite a bit of manual mode and sport mode with a good mix of city and highway.

20-22 avg with 80% city / 20% fwy on UEL stage 2 tune.

WWFT86 · 01-06-2017, 08:50 PM

17 MPG on AT with manual mode - mind you I live in below freezing temperature and most of my driving distances is done one gear lower than normal just to warm up the oil.

I believe the OP was referring to the new 4.3 FD ratio in the manual trans MY17 cars.

Only a couple tanks in...
About 50/50 city/highway. I don't typically drive in a fuel efficient manner.

5% FD reduction is typically 2-3% less cruising efficiency, if that's what you wanted to know. The stock tune runs fairly rich on heavy throttle so you can easily burn 2% more gas by stepping on the pedal a little harder. On a flat freeway with cruise control on and no wind you'll lose 1mpg or so, because physics, but it would be quite hard to notice.

This is all that needs to be said^^^.
The difference in gearing is so minor and the variation in MPG due to different driving conditions so vast that any comparison is useless.

Im posting simply to say something else since you said that was all that needed to be said. And since that really is all that needed to be said this thread doesn't have much of a point anymore
