I'm doing a road trip with my 2015 Micra. Poor little car didn't know what happened to it when it had to do 500 kms in one day instead of one month! Its an automatic but I think on the highway ....Hwy 3 in BC the Crow'snest Hwy...i have got over 30 mpg. Plus it's really packed up....with. a (short) cat tree ..no cat) and three boxes of dishes, 2 suitcases , 2 boxes of miscellaneous and a heavy food bag.
Love this car!
