I guess it had cooled off overnight so the range estimator was slightly pessimistic this morning compared with the actual range from the previous charge;-

... or maybe it is signs of early battery degradation...not! :D

Very impressive at this time of year and temperature! I've rarely reached 50, even in the summer, but the village I live in is quite hilly and I do a lot of short hops (drive of 1 or 2 miles then back again in half an hour) which seems to hit the range quickly. When i go on a longer run i can achieve a better result.

The flip side is i can keep the battery charged regularly at the office so rarely need to use the ICE at all and am sitting at around 300mpg lifetime which is better than the 25 i was averaging in my previous diseasel!

Blimey 60 miles! Impressive at any time of the year, never mind in winter. Am pretty sure mine wouldn't get that at a constant 50mph, even with no heat.
There was some Hold used on hills I believe, not continuous (from another thread on this forum)

Anyone care to comment on this 60+ miles on electric. Mainly motorway driving from North Wales to NW London. I did not drive with any special care. I did use Mountain mode to charge the electric battery, but as I understand it when charging in Mountain mode it does not count as electric and would not show in the 60+? Then immediately after I made my final stop when I arrived home the car when into the dreaded "Steering Lock" fault and would not start. This required a tow to the Vauxhall Ampera specialist and the software had to be reset. Comments gratefully received. IMG_8895.JPG IMG_8896.JPG

you used 18kwh to go 60 miles.
If you work out the miles per KWh you will find it is 3.3 which is equivalent to about 36 miles on just the battery. When that figure is close to 6 miles per kWh then you are ready to go for the journey where you get 60 miles from start full to empty with no gas or top-ups.

Thanks Rick now all is clear..

I hope I haven't put you off trying! Keep an eye on your miles per KWh when you are going for economy rather than speed. It will be harder now for a few months until springtime as the temperatures are now below the optimum. End of May to beginning of Sept is the season for it and best at either end when nether cooling nor heating is required.

We can see that! :LOL:

All the EV and petrol miles get mixed up. It is not really very easy to see. Best way in my experience is to multiply litres used by 2.7kWh (or 12.5kWh per gallon), which is the 'usable energy' the engine puts out, and convert to mi/kWh (or reverse the calculation for mpg if you prefer).

In this case you will have generated a total of 125kWh, plus the 10kWh from the battery for 135kWh of traction energy. So your total is 497miles/135kWh = ~3.7mi/kWh. My guess, this would mean you were sticking to high 70's mph most of the time.

Hi everyone,

Here you are my ticket to 60m Club, I did just a few minutes ago when coming to my job. Secondary roads most of the time, uphills and downhills, switching between L and D mode. Winter but a very pleasant temperature. Here in Spain we use metric units, but I selected UK units to show you the final results.

Thanks!

It's not accurate to believe this is 60 miles EV range, because you've been doing EV down hill and petrol up hill, as evidenced by the 25mpg you've achieved on petrol only.

You can do a summative calculation by using a petrol-to-kWh conversion of 2.7kWh/litre, which is about right for the Ampera.

So you have done; 74 miles/( {9.6kWh} + {1.75litres x 2.7kWh/litre} ) = 14.3kWh, or 5.16mi/kWh.

For a 10.5kWh battery capacity this would yield 54 EV mile range. Very respectable! ;)
