Anyone has real MPG on 2013 JCW Coupe ? I am currently waiting for delivery 2nd week of october . Dam its bee a long wait .

 

Sensible, highway driving, 55-65, AC off and windows down I have seen avg in the 38-40 range on a flat road. The trouble is I don't drive that way often!
You can expect to see the 29-33 mpg range for the most part on the highway with average driving, but since the JCW is so damn fun in the 3500-5000 rpm range expect that to be on the lower end!

City driving I see on average 23 mpg, but I try to make my spoiler pop up between lights

 

My 2012 Coupe S is averaging around 28mpg here in hilly southern California. This is my daily driver, but on the weekends, I've been known to get a little deep into the accelerator on the twisties up in the local mountains.

On a flat road, clocking 80 (normal around here on the highways), doing the daily commute, I am getting 29-31mpg (depending on congestion, or how many 'Zonies are ditty bopping down the round in the left lane, not moving over).

 

My 2010 S got a consistant 35 driven pretty hard. 2011 JCW gets about 28 driven a bit harder because it loves it.
