New roadtrip in the G4, much better hwy mpg than my 2014 hatch!!!!
Well drove from Atlanta to Charleston SC yesterday with my wife. We have the exact same tire and wheel on the G4 as on my 2014 hatch. I manually checked the mpg from Atlanta to Columbia SC and even factoring the 2.2% in revolutions on the larger tire we still netted 38mpg! And this is with me doing 70 to 75 mph the whole way with a lot of rolling hills in between. Meanwhile doing the same speed on the hwy is netting me 27 to 30 mpg on my 2014 hatch. I'm starting to think it's engine related?
