Have had my '24 RTR for a year and a half. Had an average MPG between 16 & 17 MPG consistently. Now I notice that my MPG has gone up to 20 MPG after the last 2 system updates. I haven't changed my driving habits and always purchase fuel from the same station. Do these updates affect engine tuning or am I just getting lucky? With MPG, not the other thing!! 😀 Thank You.

I have my GT for 14-15 months now. Just 3,800 miles. But I have noticed MPG is slowly improving as the car is breaking-in.

Same here at 7000km. Actually dipped below 10L/100kms ( 23.5 mpg US) on the last trip
Pretty good for our road conditions

Same here. Low 20's around town/some highway. Mid 20's all highway crusing with no traffic... I drive like an old lady most of the time though :rockon::rockon::rockon:
