Daily Motor was able to get 38.59 mpg in their fuel economy test on a 100 mile highway trip. Is anyone getting similar numbers with their Si?
That is pretty good for those conditions.Best I've personally gotten is 39mpg for a 113 mile highway trip...but I wasn't trying to achieve good numbers. That was hitting 80-85 mph on flat Florida roads running 93 octane in my Si, with just over 1,000 miles on the clock. It was unusually cool, in the 50s/60s which is cool for us in south FL.
That same trip in a different leg, I averaged 37.4 mpg for a 103 mile trip. I took pics of the screen because I was quite impressed and shocked since so many people (mostly the 2.0 trims) are getting terrible gas mileage. View attachment 6279
That is really good and it shows how much difference 5-10 mph difference can make, if you can ever do a 50 mph trip on a smaller two-lane road the numbers would be in the 50's. So well over the government rating.Usually just cruising at 65 MPH for 100+ miles, I'm able to stay in the high 40's for my Touring model. Around town, I'm in the high 20's/low 30's. Average over 13K Miles so far is 35 MPG.
One test run I did just for fun was 50 miles at 60 MPH with a big tailwind and I got 54 MPG. I'll never see that in real-world driving though.
I'm still waiting on mine to get built but I'm not too far down 85 right by Atlanta. Have you ever went to the Caffeine and Octane car show in North Atlanta? Once I get mine I was going to take her to the show.My commute is from Huntsville Alabama to Atlanta and back (about 3 or 4 times a month). I've been averaging about 38.5 MPG. The trip is about 1/2 major highway and 1/2 country 2-lane roads.
Nice I did a 30 mile drive today, and it is consistently hitting 43-44 mpg's at 70 mph. When I get my summer wheels on the car I hope to cut the weight by a similar amount as you, that should help.I’m sure the display likes to lie a bit but on a flat highway run of about 20 miles I was getting 50+ mpg fairly easily in my SI. Granted I just cut about 11lb each corner so that likely helped a lot
You’ll love it I’m sure. I’ll eventually get the 27won big brake kit which will be another 6lb per corner. That with some other things maybe we could get 60+ in perfect conditions. For a sporty sedan that would be amazingNice I did a 30 mile drive today, and it is consistently hitting 43-44 mpg's at 70 mph.

It is very possible to see 50 mpg readings on the fuel meter in perfect conditions, for short distances low load. I'm anxious to see how my Si does in warm weather months when conditions will be more optimal.
