Just filled up the other day. Drove it till the gas light came on, which is when the range showed 30 miles (same as my cx5).
386 miles, 15.8 gallons = ~24mpg
I have a fwd, so fuel tank is 19 gallons. When the fuel light comes on, that's a little over 3 gallons in reserve for me, which is also about 70 miles in reserve at my mpg's.
