Just on the fuel economy discussion, I did a bit of an experiment about 10months ago, when I was driving from home (Armidale, NSW) to work (Tamworth, NSW) with a calculated distance of 118.7km.
I drive a 2012 86 GTS 6AT which had approx 17,000km on the clock.
Stock HP Primacy tyres, 38/40psi as supplied by Toyota. Stock 17" wheels. Everything was as from factory except for ceramic pro paint protection.
I did exactly the same route every working day for about 2months, which averaged 1187km per week.
I used my other car for town driving and shopping.
The route was laid out: about 5km of not stop-start town, then the rest was highway until the last 10km which was still highway but speeds changed constantly. There was also about 7km of easy mountain about 2/3 down the road.
I used D and cruise control and kept it at the speed limit at all times (averaging out the times where I was stuck behind slower people and when I sped up to pass them).
I managed to average less than 5.7L/100km calculated by both my maths and an app on my phone, basing on how much I put in to full (where it was literally pooling in the filler from being overfull - just so I knew that it was always same) against my odometer.
I was never getting less than 850km per tank and my car never started sputtering. I do not know how far I could have truly taken it before conking out but that is an experiment I refuse to I try.
Since I have put on the new wheels (18x8.5/18x9.5 with falken FK453 tyres (245/35 and 255/35) pumped to 42/44psi) I only got about 700km max.
That all said and done and dusted...I drive in manual mode, don't shift until it's screaming (unless I'm in town) and average 7.9L/100...but I don't care...what's an extra $5/100km for that big smile forever stuck on my face.
