Ahhh but wait before you all start uttering the usual if you can afford the car blah blah. I was playing with the heater controls yesterday as I could not understand when asking for 22 deg the middle and outer vents blew freezing cold air but the cabin always felt crazy hot.
Now for the funny bit



The rear cabin was set flat out 36 deg (I think, full up anyway) and the front 22 deg as a result the heater was flat out trying to keep the rear hot and the AC was also flat out keeping the front cool.
Before I sorted the heater I got 150 miles for £50 (no playing) Xmas shopping with the wife so slow drive. 60 ish 15.7mpg calculated with fuel used.
Now heating / AC all set as it should be.
Put in £50 last night and done 89 miles so far the computer is still showing 190miles to empty and the fuel gauge has not moved. If i get 250 will be 26 mpg. I would be happy with 200 miles
I don't mind putting fuel in when nailing it but I expect over 20 when driving normally
looks like I am going to get 250 ish from this £50 ( I prob wont I will end up playing) that's an incredible difference. Just shows you the difference power consumption makes.
