I have a stock 2012 limited with about 1200 miles on it. I have filled the tank 3 times. I get 17.9 on 2 tanks with mostly city (about 80%) and 19.9 on 1 tank with about 60% highway.
I have found that the computer is very accurate on the overall mpg for an entire tank.
We are leaning towards a Limited with the upgraded JBL sound system without Entune.
I'll post what version map we have. I will also try to find out about any "free" updates when we get the 4R.
Do you only get the one that came with your 4r or do get a "free" update?
I am planning on getting a 2012 and want the latest version possible.
Thanks!
