If that includes stopping at lights than the my mean average would probably be around 15mph.
It is also very very rare that I exceed 30mph due to the roads I drive on.

35 mph for Hyundai i30 Comfort. Surprised me as I do very little local motoring, mostly medium to long range. I expected at least 40.

OK, help me out with the maths here.
As I said further up this thread, this morning my computer was indicating an average speed of 38mph since it was reset 4400 miles ago. This afternoon, after a 90 mile run up the M3/A3 and back it is indicating an average of 42mph.
This does not seem right to me. Say I averaged 60mph for the 90 miles this afternoon; (i.e. theoretical 1.5hrs running).
This morning :-
4400 / 38 = 115.8 theoretical (but unlikely) hours running.
This afternoon :-
(4400 + 90) / (115.8 + 1.5) = 38.3mph average speed.
As I say, the computer is now indicating 42mph.
Clearly, my new average cannot be indicating correctly over the 4490 miles since the computer was reset. It must be over some shorter distance. Perhaps, like Old Navy's Focus, the average is calculated over a shorter fixed distance despite no mention of this in the Mondeo's handbook. What would that fixed distance be?
As it would be a rolling fixed distance I don't think I can calculate my true average this afternoon. Or, indeed, the average speed for the 90 miles that have now dropped off the beginning of the fixed distance (not that I need to).
My brain now hurts :-)

The reason mine doesnt is that I dont care what my averages are and dont check them.
As long as my fuel consumption is ball park OK, I am happy.

Always makes me laugh when i drive my dads yaris - its ave speed is normally about 14 mph.
|
What's the point of having an indication of average speed, anyway?
|
|
dunno - I don't care enough to even look !

I guess it is the same with many other threads discussing what seems like trivia to the likes of you & me & Optimist & zookeeper. Ditto train, plane, and bus spotters!

>>As I say, the computer is now indicating 42mph.
Assume N is the distance averaged over
(N+90) / ((N/38)+1.5) = 42
Multiplying both sides by ((N/38)+1.5) gives
N + 90 = (42 * N/38)+63
Re-arranging to get N on one side gives
(42 * N/38) - N = 90 -63
As N = 38 * N / 38,
(4/38) * N = 27
N = 27*38/4 = 256
It looks like the computer is avaeraging over your last 250 miles or so.

Thanks NC. All is not lost, I actually understood your calculation. :-)
Like others I don't find the average speed calculation particularly useful; but if I have the feature then I like to know how it works.

5000 miles in one year. That's 0.57 mph. ;-)

I suppose you could, if really bored, take your average speed, if it is more or less constant and divide it into the total number of miles you have driven in your life and come up with a reasonable stab at how many hours/days/months etc you have spent driving.
Like I say, only if you thought that was interesting.........
Edit - mine's 2.997 years by the way.......

In similar vein I this morning pulled up the "interesting stats" from the dear Lord kill me now feature of the Garmin satnav I have, and it told me that since the last reset two months ago, I've done 2400 odd miles, averaged 27.1 mph, and spent 90 something hours moving and 14 hours sat sitting going nowhere. And that's just in the car.

Any driver's average speed is always far less than they believe or experience in day to day motoring.
|
|
27 MPH ... that's to & fro work = 28 miles per day.
|
sadly, my Mondy 2l petrol records 34.9 mpg average, amd that is about right , over the the last whenever. I do not bother to reset. As for average speed, it is manky , at 44mph.
I never go above 95mph, how do you get your results?
Coast?

Ave speed 25mph, ave fuel consumption 29.9mpg, not too bad for an auto petrol mondy mk2
