X5chemist will become famous soon enough
The 4.11 gears get it off the light quick. The 5 speed trans goes through the first four gears fast. Cruising 2600 RPMs is not bad. Lower would be better. A 6th gear would be nice. Mine is averaging 16-17 MPG in the city. Only one trip out town so far. It maxed out at about 24 MPG. The current lifetime since a new battery is 16.6 MPG.
