We picked up our 45e last Thursday. It will be my wife's car but I've been driving it because she is to scared to drive it. I'm not complaining
So I have been running some test in the last couple days. We live in Arizona so full air conditioning is always on including ventilated seats. I have been averaging between 31 miles and today was my best at 38 miles. Note: my home sits at about 2900 feet of elevation. So as I leave to go down to Scottsdale AZ area my range reads around 44. When i head back up it obviously goes down much faster. I took it on a test drive early Friday morning down to a lake very close to my house. On the way back. The car notified me the power demand was to high and had to turn on engine. I was going back up pretty steep hills. It did it so smooth I couldn't even tell the engine turned on. I think it's an incredible Suv. It's a big heavy car. Quite amazing it can do what it does. My wife's commute is only 7 miles round trip 4 days a week and 1 day is 32 miles. She never ever want to have to get gas again. I think we will accomplish that. Happy wife makes a happy husband |

I have had my 2021 X5 45e since last Saturday and now have a 200 miles on it, so I feel like I can add my input here.
Typically the readout when full says 40-41 miles. If you are using the air conditioning, that reduces it to about 36-37 miles of expected range when full. The estimates seem fairly accurate so far. I can easily get 35 miles of pure EV range when doing my local driving. If I were willing to suffer in the Florida sun without using AC, maybe even over 40+ miles of EV range. But I am not willing to suffer like that. My driving is 99% EV so far. After 200+ miles, my gas tank still shows totally full. I love hitting the Sport button just to make everything turn red on the screens. It changes the entire personality of the car, especially at night. The combo of the electric motor plus the 6 cylinder 3 liter gas engine, incredible performance of those working together. This car just leaps around on the highway, especially in Sport mode. I think Sport mode still uses the electricity if available, not 100% sure about that yet because I have not spent enough time in Sport mode. I am still playing with EV mode too much. I am fairly sure if you time your departure for when the battery is finishing the recharge, you get an extra 3% to 5% out of it. My car today showed 44 miles of range right when it finishes, then settles down to 40-41 later. With lithium battery packs, pack voltage settles after a few hours. Using departure timing allows you to consume that extra 3% to 5% of energy before it settles down. |

Programming the departure time cools or heats the interior and preconditions the HV battery and recharges if possible (depending on the temperature and charger) This way energy used for initially heating or cooling can be recharged before departure. And the preconditioning increases the range of the HV battery. The AC doesn't take much power, heating uses way more. And a cold battery pack has a considerably lower range. Cold temperatures reduce the range more but in Florida that won't be a problem. |

The full drive power may not be available for approximately 30 seconds after starting the combustion engine. In this case, the vehicle will not accelerate as usual.So does this mean as the engine is using stop/start, full power isn't available until after 30 seconds of each engine stop/start cycle? |

Does the 45e use heat pump? Can't find this info anywhere. Can someone please direct us to a source or document?

Any of you guys use the preconditioning? How does it work? Do you get into a cool car in the summer? warm car in winter? Does it either heat/cool the seats as well? Curious if the 45e is different than the remote start on the gassers...

I have heard it is similar to our experience in our XC 60 T8 ... yes, it will be cool if hot in the mornings and warm if cold in the mornings. My wife especially appreciates the preconditioning in the winter. Her heated steering wheel and heated seats are toasty when she gets in the car and the electrical system is all prepared and "warmed up" to handle the cold as best as possible to suffer less battery loss from frigid temperatures.

Thank you GrussGott. It seems to me 45e doesn't have heat pump; they would have mentioned it unequivocally in the manuals and promoted it in the marketing side. Very strange why they aren't using this proven technology. I am thinking about tweeting to BMW to see if they'll confirm this.

I'm believe I read BMW is using samsung batteries in a toyota design so that'd be why no heatpump if so, i.e, Toyota isn't using them?

Using the time of departure option and climatization option will result in a healthy battery even during the winter. |

So at - 40 ore heating is comfortable but also will increase your range because of the conditioned battery and the car is heated and has 100% charge. I think at - 40 you will only be able to fully charge again with a 3,6 (or more) kWH dedicated charger. The normal BMW charger will not have enough power. Heating is powered by the HV battery, not by the charger. |

If you pre-condition it and the HV battery is fully charged using 3.6 kWh charger then what type of average range do you get in supper cold days like these? Compared to summer days.

I haven't taken delivery of my 45e but I own a Tesla (similar to the 45e, no heat pump) and my range drops by about 40% on very cold days with precipitation so I would guess based on the 30 mile EPA rating, you will get around 20 miles with the 45e on a very cold and snowy day...

Single digit or lower. I did drive to Steamboat Springs from Denver last winter when temperature dipped as low as -10. Also hurting the range significant elevation change, snowfall, and highway speeds and I barely eked out 180 miles from my car rated for 322 miles of range.

Thanks Moody for the clarification. I live in NJ, was hoping you weren't going to say like 20's-30's....worst case...we have the nice ICE anyway!
Another question - if the car has say 10000 miles on it, will it tell you how many miles are on the ICE and how many on electric? |

IMO anything more colder than negative -20 degrees Celsius or negative -4 degrees Fahrenheit is generally considered very cold days in Canada.
