Not all of those inventions are bad. But not all of them are coming from a place of necessity. All of them do increase complexity. My gripe with Mercedes is not that they are constantly pushing boundaries on what can be done with more tech. My main gripe is that the EVs they are building are essentially as complex as the ICE cars and follow largely the same design principles as the ICE cars. For instance, in the EQS,…

> "instead of applying engine breaking when the driver takes their foot off the pedal, they went to great lengths to _move the break pedal_ in proportion to the amount of engine breaking that is currently being applied as per the VCUs command" Regenerative braking slows the car more aggressively than an ICE where you take your foot of the gas, so the pedal change isn't putting on the brakes, it's communicating to a d…

It depends how much you draw from the motor/generator. One can modulate it as they want, whatever can't go into the battery due to chemistry or drive constraints can be disposed of as heat.

It would have been awesome if that article had, at any point, explained what an electric axial flux motor was, and why anyone might want one.

A very good YouTube video from Munroe Live (an engineering firm specializing in "design for manufacturing") explaining it: https://youtu.be/dCO633KE7RA "Axial Flux Motors Explained" Edit: a video from them on this particular YASA tech being discussed : https://youtu.be/m507ryWhc6c

Never become dependent on doing hideously complicated things. You will eventually struggle to choose to do something more efficient, as the european auto industry is currently displaying. The car where thid motor will be used will, given current market sentiment, be a massive flop. Here they are showing off how complex the manufacturing process is. Surely we’d all be better off with simpler and cheaper processes.

Efficiency and cost savings at scale usually involve an increase in complexity: in mass manufacturing, complexity is generally a fixed cost and so can be amortized over larger volumes.

Click "More" and scroll down: "In contrast to conventional radial flux motors, the electromagnetic flux in an axial flux motor runs parallel to the axis of rotation. The key components are arranged in a disc‑shaped layout: two rotors sandwich the stator from the left and right. This design enables an especially compact motor architecture, high power and torque density, and new freedoms in drivetrain packaging. In the…

Really the kind of thing that should be earlier in an article about… that very thing the reader is wondering about, but maybe we arent the target audience?

Here's a good video on it from my watch history: https://www.youtube.com/watch?v=dCO633KE7RA

This one gives a shorter more high level overview https://www.youtube.com/watch?v=B0CNZPenCb8

The AI voice is annoying, the content is as personal a a vanilla yogurt but the animation is clear.

I want a V12 or V16, thank you very much.

I'd like a 600 HP 1.5l supercharged V16 - doesn't even need to be in a car, mainly just to listen to! https://en.wikipedia.org/wiki/British_Racing_Motors_V16

Then all you need is a good recording and decent headphones

Great video. I didn't know I was so interested in engine design before I watched it.
