On a highway trip a few months ago our display was showing 7.8L/100 km. And that was for: KX-R AWD 91 RON good tyre inflation (38 psi) 2 passengers Oh, did I mention it was a learner driver? 80 km/h :) More realistically, on an extended highway trip with mix of learner driver (80 km/h) and normal driver (100-110 km/h), 5 passengers, A/C on, cruise control on, lots of luggage inside and full "granny box" on top, the display hovered around 9.1L/100 km. I am still impressed with the fuel consumption. I've never tried 95 RON but others in this forum say it will lower the figure. Ken.
