I would not say it faster, according to BMW 0-60mph are the same, some tests show that 45e faster, some that 40i. Anyway, the real difference is around 0.01seconds between them. Yes, it is efficient due to electric is cheaper than gas and thus BMW shows much better MPG during electric/mixed ride than gas.

Also, regarding regeneration, coasting is more efficient than regeneration since conversion of energy inevitably leads to losses. it depends on driving style, if a driver used to hit brake right before red light then regeneration might be better, if a driver have an ability to properly use coasting and traffic allows it - then it will be more efficient. |

FWIW, the logic in the vehicle does make decisions on when to use regeneration versus coasting...they talk about it in the user's manual, if anyone actually reads it. Some of it is based on the navigation system knowing where you are.
If you learn how to feather the accelerator, you can coast all you want. |

And if you don’t charge 45e at all and use it as just non plug in hybrid, if you believe BMW document, 40i is more efficient. |

your concern is duly noted in this thread, your other thread, and your thread in the FB group. none of us can convince you otherwise despite providing reassurance and some evidence that the risk is low.
it can happen. why? because there’s a big battery inside! it’s up to you to weigh the risk of owning a 45e and it actually happening. i suggest looking up its predecessor, the X5 40e, to see if it has a track record of battery fires. don’t forget to differentiate between spontaneous (short circuit) vs impact-related (crash) vs user error (charging protocol neglect), etc, if the data exists elnoraao2 what was the the financial impact on the person you know when the fire broke out in her garage, and she forgot to change the charge rate limit after the Tesla update? |

of course, the more info you can gather, the more you can make an informed decision. mine is a MY21 and was a spontaneous purchase. I’m a very technical person by nature, so learning the hybrid tech (and it’s inherent risks) didn’t bother me. I really enjoy it! |

But your question, while a good one to ask, is CLEARLY illustrated in very large scale data pulls from across the country over many millions of vehicles (hybrids, PHEVs and EVs). The results are clear.... if you are worried about fires, DON'T buy an internal combustion engine vehicle, and especially an actual hybrid (like a prius) as these types of vehicles have the highest fire risk of all. It is really that simple. But hundreds of millions of people own ICE vehicles, and hybrids, and EVs/PHEVs, and relatively few burst into flame spontaneously (which is what it appears you are worried about). Asking your question on this website (which is more than welcomed for sure) is asking for personal opinions on the mechanical and electric risks of a vehicle that none of us have built and probably few of us have spent the time evaluating from a data perspective to give definitive answers. In the end...it seems like you would sleep better not having a PHEV or EV, and that kind of reassurance is invaluable |

But still, Tesla or any BEV is very different than PHEV. 45e charge at 16A for 5 hours. Much much milder and lower risk then BEV charge at 40A for 8-10 hours, which is very low to begin with. Assuming infrastrcuture is setup properly.

There's a good reason why a properly set up EVSE should never pull more than 80% of the circuit's capacity.
The other side of that is all of the connections must be secure...one reason why I prefer a hard-wired EVSE versus one with a plug on it. Sockets and plugs wear out. When you push the plug in, if it isn't hard to do, you potentially could create too much heat from the poor connection, and have problems. Even with the supplied, level 1 EVSE...builders' quality receptacles may not be sufficient for an extended higher load. |

The background was like this. she set charging limit in her Tesla to 24A. The EVSE itself is a 40A model, but on on 30A dryer circuit. I am not sure why, but it was what it was. For years, the car pull 24A, everything worked just fine even with multiple OTA, until one night that version of OTA reseted the charging limit. She set charging start at mid night. So car start pulling 32A. ~1am fire started in wire.

Yes, that is a nasty situation! But, regardless, IMHO, a device that COULD pull 40A has no business being installed on a 30A circuit, especially if it is software limited and OTA updates could be applied. Programmers make mistakes and pressure to release software doesn't always find all of the bugs until something happens.
I do own an adjustable level 1/2 device, but it requires you to reset it each time prior to plugging it into a vehicle. FWIW, at least when used at home, the places where I could plug it in are sufficient for the 80% rule. That device was bought as a backup, in case of travel, or the hard-wired one happened to bite the dust. |

'23 x5 45e owner here, bought last year.
I prefer a quicker pickup, even in sport mode, which doesn't have to achieve sub-3s. (definitely would splurge on a M + EV option of (x5ME?)) Things I feel disappointed in so far: would prefer a minimum of 50 miles of EV range 30 miles doesn't do enough for me Combined ICE+EV range >450 |
