2012 Sport, CVT.
So I just finished a round trip of about 700 miles between MD and CT. I was at about 12k miles at the start, having only completed the 7500mi oil change. The trip was 95% highway, and was fairly varied elevation wise.
Each way consisted of 1 tank of gas. I averaged 32 MPG via Fuelly, 34 MPG on the digital read out. I stuck to 62 mph in 55 mph zones and 65 mph in 65 mph zones.
