My 340 is lowered with Dinan springs and I’ve got Koni Sport yellow shocks at the stiffest setting. The ride is firm. I’m not sure the X3 M would actually be more firm than my current ride. On long trips, it’s not a problem for me.

However, my 340 will get 32 MPG driven normally at speeds around 75, and it can get 28-30 mpg at 80-90 mph assuming no headwind. Range is usually 450-550 miles on a tank. Pretty effing good for long road trips for a car that can do 0-60 in the low 4’s.
