Just read an article on Autoblog.com that had EPA numbers regarding what the JL Wrangler will get in terms of MPG. As some of you know, the JK with it's 3.6L Pentastar with a 5-speed automatic gets 16 city, 20 highway and a combined average of 18 MPG. According to the EPA, the JL with it's 8-speed automatic will get 18 city, 23 highway and a combined average of 20 MPG. Not a huge difference but there is an improvement.
