More like a weird rant that reduces EVs to only existing due to the environment. But they’re just better cars lol. And the poor reliability of european cars applies regardless of propulsion type

They aren’t better cars if they are disposal items like phones and most electronic devices.

Depends on the brand and the model, there is a trend towards higher voltages because that implies lower currents and wiring is heavy and expensive. It started out with (nominally, voltage can rise and fall based on charge levels) (30S) 144V packs, (96S) 352V is very common and there are (192S) packs that do 704V (but that are marketed as 400V and 800V respectively). You don't want to get zapped by any of these, it's…

Yikes, that sounds dangerous. I'd personally prefer e.g. 48V even if that meant some more losses and/or thicker cables.

Running an EV off 48V would lead to a heavily, heavily compromised vehicle. There just aren’t components that can handle 5-10kA of current with a reasonable size.

High end ICE cars have long been treated as disposable items. 3 year lease and then resell for 1/2 of its initial price so suddenly it’s cheaper than new midrange models for good reasons.

Lower end cars on the other hand can be worth 3/4th of their initial value 5 years out, that’s a durable good.

> It’s a fuse plus guarantee plus liability. This is BMW we're talking about. Their guarantees are worth absolutely nothing if my experience is anything to go by and them accepting liability is not something you should have to pay 4K for if other brands can do the same thing under $100.

They'll refuse warranty on the XDrive if you don't use approved brand and model of tyres so... my bet is on them wanting to extort all the precious money they can from their poor customers

They'll refuse warranty if the difference between thread is too much between front and back as that causes wear of the clutches. Just like you should have the same tire on the same axle.

Or if the tires are not the right size, especially in staggered setups.

If you come from a car that is FWD with AWD capabilities, it doesn't matter as much.

But BMW (at least the ones with the engine mounted longitudinally) which have xDrive are permanent AWD.

Is it insane? I'm working in this field, and I know how quickly you can come up with such a number if you are BMW and you are deathly afraid that someone will get electrocuted while working on your car, driving it or rescuing someone in a crash. It's a safety and liability issue, where they go to great lengths to actually re-certify a battery after crash. The whole thing is setup so, that even the dummy electricians…

Many people drive older cars worth less than £4000. Sticking to old/cheap cars seems like an increasingly good option with so many scare stories about the pain and extreme expense of getting modern cars, particularly EVs, repaired. And the impending ban on new ICE vehicles seems likely to lead to more older cars being kept on the road for a lot longer.

ICE bans are going to cause the value of old cars to skyrocket

After reading the blog post I had the same thought. Doing an oil change on my F650GS motorcycle required removing the plastics, draining the oil from both the top and bottom of the motorcycle, removing a plate on the side of the engine after install the BMW specified oil redirection funnel, extracting the filter and reinstalling. The oil funnel had a legit BMW part number. Most of us either just made a mess or used a…

Wait until you see a picture of a clutch replacement on an R1200... this should probably have a NSFW tag attached: https://www.reddit.com/r/motorcycle/comments/1he20rk/r_1200_...

Thanks for curing me of my desire to get one of these.

€4000 euros plus tax to replace the module that contains the fuse. Insane. The ford transit custom PHEV costs £4500 to replace the timing belt. Access issues mean dropping the hybrid battery and parts of the sub frame. Compare with the mk8 transit, i've done the wet belt myself on that and it requires no special tools (well, i bought a specific crank pulley puller for £20) and can be done in a day on the driveway. I…

If you and BMW are correct - if we take it for a fact that a simple fender-bender can make batteries develop life-threatening faults, which absolutely require a 4k euro inspection that involves complete disassembly and specialist equipment, then that means that EVs are unsuitable for public use.

So either all EVs need to be scrapped forever, or BMW needs to engineer a more tractable solution to the problem, or BMW is overreacting and overcharging customers.

I have a BMW G20 3-series. So far I've counted 31 electric motors in the car for various things. I keep discovering more.
