The B58 in our G42 M240i blows those two engines out of the water in every way. If it returns 30mpg avg. I will be shocked.

My advice is to drive in Adaptive mode where the computer will target efficiency 90% of the time and switch to Sport at throttle/gear change when directed. It blows comfort away.
