Thanks for posting that. Of course, this far in advance, some of these details may not be spot on, but I'm sure some of what's here will come to pass. Automobile actually published a similar article a few years ago, and some of the vehicles they predicted then are not on this list. I would expect a future version of this article to yield similar revisions.
One thing that stuck out as interesting is the two-speed transmission. I have seen other recent articles about some future EVs using two-speed transmissions. Although this adds complexity - a single speed step down gearbox is much simpler than a multi-speed gearbox - it will allow for a better compromise between efficiency and top speed. |

some transmission for EV makes sense, you can get even higher speed, and lower torque than otherwise.
though given that much EV coming out wonder why BMW still stick to their one platform works everywhere instead of dedicated EV platform (guess a lot hybrid in the mean time) |

It is a smart choice, the kWh needs will drop significantly at highway speed which will make range easier to attain. We can get 75mi out of the 14kwh pack in the volt on side roads but only around 40 at hwy speed.
I’m interested in seeing if the i12 engine is the b48e from the m35i, they probably just upped boost to 26 or so psi to get the 340hp and having the electric motor will conquer lag. |

What jumped out at me is this: "Although details are still sketchy, we hear that BMW M is zooming in on 500V charging with a possible 800V upgrade by 2023, which would reduce the charge time of a large battery to less than 20 minutes. " What range anxiety? P.S. What happened to your quadruple clutch super rare M3? :P |

BMW is definitely on the "E" front...

Honestly, they should delay it and wait for the i4 so that it can share the same drivetrain. We know that vehicle will have optional AWD as well as both 60kW and 80kW battery options, with even greater capacity ones likely to come later. |

Guess iX3 is more for "urban", i.e. non US long travel country

Yes, and I'm thinking they can get more out of the 2.0L if they're having an electric motor cover the lag.

It's not as simple as swapping out there (~$100,000) fast charger, either-- 50kw is already around the power consumption of an average US neighborhood. The infrastructure won't be there for a while to power faster chargers. I suspect most of these fast charging cars won't be able to utilize anything close to their max charging speed for a long time yet.

Multi speed transmission on performance EVs is already a solved issue. The answer is you are better off putting the weight that the multi-speed transmission would have cost into bigger motors with more power and torque. In other words, 1 ratio.

We use our EV every day and charge it at home overnight. I took it on one road trip once, and won't again until the infrastructure is vastly improved. For road trips, we take ICE cars (normally the M5).

I’m highly amused at the idea that BMW eventually gets sued by Tesla because there already is an electric “M3”
On a serious note...hybrid powertrain making combined 750hp is quite interesting if these things are going into sub $150k vehicles. I mean the X8M can go eff itself but now thereÂ’s the prospect of this powertrain getting stuffed into a different car (one worth buying) |
