I found something about the 2014 M6 that I do not like. The MRCC is annoying and potentially dangerous. When driving on the highway, if a car changes lanes in front of you fairly close with the MRCC on, either 1.) the throttle closes, or 2.) the trans downshifts - even if there is no need to do this. That's extra wear and tear, and hurts fuel economy as you accelerate back to programmed speed. With conventional cruise control, you just touch the cancel button if it seems too close.
Last week, while driving on Route 80 westbound with light traffic at 65MPH, in a spot where the highway twists to the left, a tractor trailer was ahead slightly in the right lane. The MRCC picked up the truck and applied the brakes hard - causing traffic behind me to do the same. Luckily there were few cars and all followed at safe distance.
On a country road at a steady 50 MPH, if there is a slight down hill, the MRCC will downshift to hold the programmed speed instead of coasting and taking advantage of gravity and momentum. More wear on the trans. So what if it goes from 50 to 52 MPH?
An expensive and unnecessary "improvement" over conventional cruise control. In all fairness, I can see how non-car people would think this is great.
Other than that, this is an excellent automobile so far.
