I've had my M135 for 2500 miles now and have been running the journey computer since day 1. Average speed over lifetime is 38.5 mph. I'm a bit surprised how low it is. I live in the country so I dont spend ages sat in city traffic but equally I dont use motorways all that often either. Roads around me are fairly good, very few tiny country lanes with blind bends. Car is driven by me and the Mrs (a petrolhead) although we are both more sensible with our daughter in the car. Just wondering a) why I bought a fast car and b) what other manage.....
35mph average at the moment. Mostly from village to town and back on short runs, then some fairly long drives when we go on holiday. Been on a holiday a couple of weeks ago so that has raised it, but generally I do drive like a f
king moron BMW driver which helps keep the averages up.

Stopping at lights/roundabouts/etc. absolutely kills average speed.
This - one of my cars never really gets beyound about 36mph average (never reset since purchase), despite extensive motorway work. But idling the engine at the end of a drive to let the turbo spool down ruins the average speed. This is what makes Chris Harris' average speed in a Panamera of 49mph impressive/concerning (delete as appropriate) - see here http://www.pistonheads.com/news/default.asp?storyI...Gassing Station | General Gassing | Top of Page | What's New | My Stuff
