Mind what we trash-talk
Read on another (un-named) auto forum how they are smiling at all of the growing and public i8 trash-talking by current owners. Their comments were that "...resale prices will be dropping quite a bit, real soon....then we can pick one up for a greatly depreciated and decent price...".
I don't particularly love my e-range either (best was 19 miles), but still love the car and use it mostly in Sport mode anyway. After the disputed European data and then the U.S. EPA estimates, I never really expected 22 miles. If I wanted a mega-electric car, I would have bought a much different model. |

Here is a link to one persons test, the got 22 miles on electric. Lots of details. I do wonder if the preconditioning, which also preconditions the battery but ONLY if departure time is set in advance, has something to do with it. I've asked the author. Will try to do EV range test this weekend.

Do you really care about ev mileage? I don't

I am interested in electric range without every so often going into sport or having the engine start. That test was not all electric.

I bought/am buying this car for its style, beauty and performance. I really don't care how many miles I get on electric only. For that matter, I've never cared how many miles per gallon I have gotten in any of my cars.
I just enjoy driving well designed (for handling) and fast sports cars. The electric part of this equation is for the torque not the gas savings. Did Porsche or McLaren or Ferrari put electric motors in their cars to get better gas milage so their owners could get to work on all electric power? No. Lets talk more about how great these cars are as a drivers car not a commuter car. |

Yes sir. That torque is very strange yet very satisfying on my i8. Addictive fosho.

I do understand that some owners care about the electric range, but:
1/ I personally don't care, as approx. 16 miles are enough for me. It's a hybrid. 2/ I don't want bigger batteries, due to weight 3/ BMW always advertise the range as UP TO 23 miles (or whatever figure). That language is deliberate and important. 4/ When I test drove the car, it was clear to me very soon after going into E drive that it would only manage around 15 miles when driven without being economical - as I would drive it. ....and again, it is probably the least important aspect to me personally. |

The one referred started as all electric I though until it ran out? Even if not then question is if I get 25 from regen added does that count? |

The question is what is the maximum all electric (or electric only) range. BMW has said 35-37 km or 23-25 miles and, more recently "up to 15 miles" except when it enters green car contests when it dishonestly reverts to the earlier figures. The actual all electric range is between 12 and 14 miles. And you can get the 14 miles only by not driving it normally in the real world.

1) Fully charge the car, 2) Set pre-condition for exact departure time, 3) Drive in electric ONLY (never allow engine to turn on), and drive around until engine turns on (including regen) 4) DO NOT descend any significant (not climb) elevation. Anything else? |

I did a re-test yesterday at about 2 pm. Temperature at the start was 72F and went to 79F. Car had been fully charged on the BMW charging unit for about 45 minutes and was in a garage that had been at 72F for at least 8 hours before the test.
I averaged 29.9 mph per trip computer, including stops, in suburban and urban traffic. I had about 8.8 gallons of gas on board. (But the goal was not to use any and see how far I got.) I drove in EcoPro mode. I achieved 21.0 miles this time electric only as opposed to 21.3 on Easter Sunday. Elapsed time was 40 minutes. Aircon was again off but fan was on and I opened the windows a few times. This time I accelerated a little more vigorously and hit 50 MPH a few times. Gentle hills for first 7 miles. Starting elevation above sea level: 1050 feet. Elevation when ICE kicked in: 870 feet. Most important stat on the trip computer was, again, 4.1 m/kWh. Based on these two tests (which, again, included some hills) I believe that BMW has fairly represented electric range. BMW backed down and said that for US spec cars electric range was "up to" 15 miles. And it is. And more. Close to the 35-37 kms in the European and world brochures. One thing I have found out is that if you start out going up hill and then level out, or otherwise start off driving more sportily, you seem to "condition" the battery to discharge more rapidly. If you start off slow and steady, and avoid hills, you will get more range. If we had access to more of the battery's reserve, we could increase electric range significantly. (7.2kWh x 4.1m/kWh = 29.5 miles.) Edited to add postscript: I thought this was the thread where I posted my previous report about my electric range o an Easter Sunday test. It isn't. Sorry about that. In that post I reported 21.3 miles electric only.

Theoretically BMW should be able to provide that in firmware. But then again I wonder if the engine could charge the battery if it was too depleted.... |

I believe preconditioning the car (telling it when you estimate you'll be using it) may also affect electric range -- in a positive way.
I will test that out in a few days. Right now I have to play with my new toy. I just turned in my 650i Gran Coupe for an M4 coupe.
