I did not precondition. Garage Temp, 78F. Ambient Temp 85F. I unplugged from the umbilical and started the car. At this point the range was 15 miles. I backed out of the garage, down the driveway, and onto the street. A total distance of 75 feet. I engaged drive and immediately went to eco-mode. I drove off at a reasonable pace keeping the power level at 60%-70% of available eco-mode power. To make a long story short, in mixed driving with about 65% on the interstate and never over 74 mph as well as judicious use of the accelerator, I achieved 23 miles when the range meter hit zero. This included regeneration from coasting and braking but the ICE was not started. I drove another 100 meters to a fuel station and filled the car in order to get a good reading from the App. More Data: 4.1kW/H/mi expended for the 23 mile drive. I will take this any day of the week!!! For those who have done this, please share your methodology for the measurement. I would be extremely interested in developing a consistent methodology. Great Job BMW!! Last edited by MKSixer; 08-25-2015 at 02:49 PM.. |

I think pretty much, yes. I've done 37km, which is also 23mi (post #28 in this thread). That's the most I could get so far - on a flat run, not benefitting from an overall drop in elevation or anything (actually, it's a net climb of 5m )

Did another 37 km / 23 mile run yesterday. It's starting to be the norm if I go home late enough and take the back roads. |

My car seems to have moods. E-motions?
I have done the same run where I managed 39 km (see above) a number of times. I always charge up the same way - 16A 220V fully charged, no precon. I always drive home the same way. Sometimes traffic doesn't let me cruise perfectly; I get that. But still - for instance today: same drive, fairly empty roads, no adverse weather conditions like headwind, no a/c, .... I tried to drive just as carefully. But I had a hard time getting under 19 kWh/100km on average, compared to the 13.something above. I've observed these fluctuations for a few days now. Not sure if it can be outside temperature. It hasn't changed that much. Any ideas? |
