Re: 2014 i3 getting only ~40 miles on full charge

Now that they have tested it - and by fully discharging and charging the cells several time, which should cell balance the battery pack, see what your battery kappa is now, and what range you are getting.

Did they waive any of the charge they previously quoted for the diagnostic work?

40 miles range was unrealistically low even for a 14 kWh pack, implying just 2.9 miles/kWh efficiency. I’ve never had anything remotely close to that even under 5F / -15C ambient temperature. With the 16 kWh battery, implied by the test results, your range should be north of 65 miles (EPA range based efficiency, easily beatable in real world).

I will do more thorough testing now that I have the car back. Hopefully their charging and discharging will have helped.

Also, I dont think they waived the $300+ fee but Carmax is paying it and not me. I will have to put another post on this but Carmax has been amazing experience for used car.

I have to say that the 3.8m/kwh figure for a careful driving is rather low. When I had a REX I averaged 4.1 year around, and I live in MD with a relatively cold winter.

I wonder if I am just heavy footed. In my Fiat, I averaged 3 mi/kWh and would really try hard to get past 4 while my father could consistently get over 4.

Well, there are the makings of a practical test - have your father drive the i3 for an hour or so, so the car has a chance to recalibrate the range 'guessometer' to his driving, then fully charge it, and see what range is displayed when the car has 'learned' his driving style.

Where is this car? I'd like to take a look at it.

Look in the BMW Connected app, under eDrive, and it will show your Efficiency rating, out of 5,
