Ok...I took the M6 out this morning to the coffee shop for a proper thrashing and returned to get the i8 for my lunch appointment and decided to have a proper measurement of my purely electric range. Here are the results:
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!!
