Ahh. Nope. The wife has what I call BMW ICE Lead foot syndrome!! She left yesterday morning fully charged with 39 mile range on the battery and managed to use it all in just 30.5 miles!! She said as she pulled into her work car park the Volt ICE started up as she had used all the battery.So the last 200 yards was on ICE but it was so little the car didn't register it as used. Hence the full charge needed at work.Not sure if I'm being dense, but how is all that working out? Did you set off with a partially discharged battery? Given that 13 kwh was taken at work, it would imply the battery was empty. Are you saying there was a theoretical mileage of 71.2 miles?
When I queried her about this last night and asked how fast did she go on the 15 mile streach of bypass to my kids school she replied "oh the usual 85-90". FFS!!! Today I asked her to try it at 80mph tops to help the range.
She just called me, car started this morning with 37 mile battery range and arrived at work 30.5 miles later with 1 mile range, but she limited herself to 80mph max.
She's happy now that she doesn't have to crawl at 60mph yet and i'm happy she at least makes the to work journey all on battery with just a little to spare and no ICE used. Deep Winter may be a challenge though. Will have to try and slow her down if the ICE kicks in to much in the cold weather.
