Maximus drive unit for R2 / R3 / R3X - more specs & photos from RJ

I guess I don't understand why these are so damn big compared to Lucid's motors...not an engineer, so I'm stewpid.

Why does the Gravity do 0-60 in 3.4s when it has 828 hp?

That is a great observation....how involved is the replacement.

Looks to be about 16 cover bolts and about 13 PCBA bolts. No idea yet of how accessible it is in the vehicle.

RJ, post a pic of the other side of the circuit board. We want to know what type of power modules…IGBT or SiC.

That is an aluminum casting, right? I'm not an engin-eer, but that's the most complicated casting
I could ever imagine.

These are motors, inverters, electronics, reduction gear, etc all in one. Lucid and Koenigsegg only tout the motor generally.

My quad Bosch motors never failed. My enduro drive unit did, and my other enduro car is now squeaking.

We’ll see how reliable these turn out to be. Rivian hasn’t been able to design for reliability so far, as I’ve had issues with compressors, on-board chargers, suspensions, light bars, HVAC, and tailgate latches in addition to drive units.

It's an improvement over the Bosch and the Enduro but Lucid Electric Motors still blow these out of the water on about every metric.

Which Lucid starts at around $45k?

Not on COGS, which is what matters. Last I checked Lucid isn't even close to positive contribution margin and that's without the massive capex, service infrastructure, and charging infrastructure that Rivian is cranking out.

Making an exquisite piece of machinery that costs you more to make than it provides in value is not particularly impressive IMO.

IIR Their motors cost less to build than any of the competition according to them. This was in an investor day or tech day presentation.

I find it very difficult to believe all things considered.

Hopefully Lucid will survive as a tier 1 auto supplier where the industry can benefit from its designs and does not just get absorbed into a bigger player.

They’ve got Saudi money, so they’re not going away just yet. I’ve only seen one or two Lucids in CBUS. I don’t know why they’re not more popular, especially among the rich. I guess sedans just aren’t luxury enough. Maybe the Gravity will make a dent.

Are those hairpin stators?

The people who run the Saudi PIF are very savvy and demanding investors who won't throw money away. Lucid's efforts to support the IKTVA (in Kingdom Total Value Added) agenda by putting an assembly plant there has bought them some more time, but the idea that "Saudi money" is some bottomless pit of cash to be had is very wrong.

The design decisions and the timing of the launch for Gravity have both been unfortunate. I do not think they make it through the next 12 months without being sold. But there is value in their technology. I would like to see it wind up at a Tier 1 but I suspect it winds up instead at an OEM.
