@HumBucker Why is GM's Ultium drive system not this efficient and compact? GM's best motor weighs more and only makes 350 hp, might even cost more to make since extra weight is usually extra $$. This thinking requires inventing new production systems, and thinking outside the box, things GM does not seem to be capable of for whatever reason? GM is full of Lazy engineers (and managers) that prefer to just refine existing technology, no thinking outside the box, and truly new invention.This is very interesting, motor weighs 67 lbs but generates 670 HP, 10-1 power to weight ratio. Not traditional Hairpin, and not traditional Wire Wound
GMs design had different specifications. GM wanted to design 5 drivetrains and 3 motors to be used in a host of vehicles. Lucid designed for one. You can't judge one design better than another without knowing cost, capability, manufacturability and durability. Lucid has no plans on making a $30k vehicle that uses the same motor technology.@HumBucker Why is GM's Ultium drive system not this efficient and compact?

Love Peter bashing on Tesla Plaid and Porsche Taycan motors...
Totally fair comment, but why not design one great drive unit that works in nearly all applications (front and rear the same)? Because a motor "can make" 670 HP does not mean you have that in every vehicle, that is all inverter tuning. In the Lucid they have a 2 motor car with 600-1111HP, and a 3 motor with >1200HP, its all inverter tuning, how much they want to push the motor in each application.GMs design had different specifications.

I will say it again. If you're trying to manage cost, complexity, repairability, reusability GMs approach makes perfect sense. GM will be able to make millions of their units. Looking at how Lucid cools the motor it's a lot more complex than GMs solution. GM directly cools the end of the pins whereas Lucid runs channels alongside the pins.Totally fair comment, but why not design one great drive unit that works in nearly all applications (front and rear the same)?

What are you talking about? Lucid has delivered more cars than GM has Hummer EV's, and Lucid Air is not only a new car with new technology, Its a new company. Stumbles are expected, and stumbling with production is deflecting from the topic, the Lucid motor is more efficient, holds power longer (Hummer de-rates after 4-5 seconds). Lucid pulls laps on the track with no de-rate of power, so their cooling system trumps GM. Lucid Air is also the most efficient EV made, 4.5 miles per kWh, GM having trouble getting 3 miles per kWh from Lyriq, and that is with RWD, and very low power.I will say it again.

Lucid did some great engineering for a car they are having issues getting out the door. Granted it might not necessarily be drivetrain related.
Agree, Rawlinson is a real engineer, and Lucid has dug deep with their car technology, whether they will be a business success is not known, I would put odds at less then 50%, but their technology is impressive and others should be paying attention to the high water mark. If I was running GM I would be looking at all the best technologies, and asking for detailed explanations inside as to why ours is not as good?Rawlinson is a real engineer and memorizing to listen to.
They also have extensive experience with formula E racing.
When people talk about a cars "technology" this is what that should really mean. Not an infotainment screen to play games with.
I think you're discounting GMs engineering. Without knowing the requirements for Lucid or GMs design you can't judge how good they are. GM plans on making millions of their motors and selling vehicles from $30k-$200k+. GMs units are larger and probably heavier. But that could be a design tradeoff for easier to building.Agree, Rawlinson is a real engineer, and Lucid has dug deep with their car technology, whether they will be a business success is not known, I would put odds at less then 50%, but their technology is impressive and others should be paying attention to the high water mark.

Ahh, come on man, don't be suck a homer boy, it's embarrassing. Rawlinson getting over 500 miles of range, over 300 kW charging, and over 1200 HP out of a 118 kWh battery, GM is not even close, and still in Little League when it comes to EV technology, they have not even caught up to Tesla yet, then its another magnitude past that to catch up to Lucid.I think you're discounting GMs engineering.

It would be interesting for GM to do a like video explaining the choices they made, but they have no reason to ever do such a video.
