It's poorly worded. There aren't three motors per axle, there are three motors total: one on the front axle and two on the rear axle.

China is working on the same type of engine: https://interestingengineering.com/ai-robotics/chinese-axial...

Ye, and I’d wager China will put that motor into affordable vehicles first, not some BS AMG GT 4 door/4 seat hyper car.

Mercedes always brings their latest technologies to the highest tier of cars first. Almost every major innovation has first debuted on the S class

Ah, another fantastic British innovator (YASA) having to realize its potential (and ultimately the downstream economic benefits of commercialisation) abroad. Brought to you by the only country to have a space programme and abandon it.

Did they have to? My impression is British companies sell out as soon as they can these days. Is this something that could be changed with policy? Does Germany incentivise running companies more? Or is this cultural, e.g. British people are more risk averse?

It's very difficult to raise late stage capital in the UK, especially for deep tech. We invent so much but our capital ecosystem is all tied up in land and our pensions providers don't want to know.

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.

He says, typing on one of the most hideously complicated things humanity has created.

I got the impression that there were three motors altogether and they were integrated with the axles.

By that logic we should all just be writing assembly manually. Screw hideously complicated higher level languages. Screw LLMs in particular, so complicated!

The UK is by far the best country to raise venture capital in Europe, and is the third largest market in the world after the US and China...

The translation's a little woolly.

For the AMG GT4 there will be 3 motors: two at the rear, and one at the front.

My interpretation (and my German's pretty lousy) is that each motor is combined with a gear system in a single package, and they're calling the overall package (motor plus gears) a High Performance Electric Drive Unit (HP.EDU).

The two rear motors will probably be independent, so no need for a mechanical rear diff (it'll be electronically controlled).

There's no mention of a front diff, so it's unknown whether that's built into the front HP.EDU or is a separate mechanical diff).
