Munro posted a new vid showing the rear Lucid motor assm.. Center diff, stacked halbach arrays, and continuous wave windings! Worth a look.
469 horsepower and is capable of a max rotor speed of 19,500 rpm.
Additionally, the drive unit only weighs 70.5 pounds (32 kg)
14.7hp/kg
I think they're using the front axle / motor in Formula E for regen only.Not sure what the changes are on the formula E platform powerplant. They were restricted battery pack wise on the race platform and that could explain the lower claimed power numbers compared to the newer road version.
I hope their packaging and build efficiencies will end up in other products or at least push others to improve. Or maybe they will sell their motors to others. I haven't been able to find any info on being able to buy them.Nice to see a bit of throwing everything at the wall approach leading to some excellent performance levels for those that can afford it. Many of the little tweaks can over time be incorporated into other features or parts and cost reductions should follow at the same performance levels.
It was great to see the two powertrains side by side. But it would have been more apples to apples to see the plaid vs the sapphire on the table.Munro does a nice summary of the drive units, and comparing the complete package performance to the Model S Plaid. 900V in the lucid vs 350V listed for the Plaid.
The Lucid efficiency numbers are a bit better than other manufacturers. It's an extra 25% range vs the Tesla setup if true is why I mentioned it.3.96 plaid vs 3.99 for the lucid miles/ KWh going by results. Forget the OEM claims IMO. Hoping to find some dyno runs for the lucid to see how that also compares to claims. Looks like potentially a great crate motor for a older sports car. Super light.
The sapphire rear motors are compact but pretty wide even for a large car,Interesting comparing the dual rear motor tesla setup vs the single motor lucid. The sapphire would eliminate the smaller center diff on the rear. It would keep the dual reduction gear box setup as on the Plaid rear, however they are much more compact.
Do you mean the early 2 speed Tesla gearboxes?Given the issues on early tesla reduction gearboxes, the smaller lucid units may not hold up as long.
The higher voltage means a lot less current for the same power levels. Less heat, less copper, less weight but more insulation and potential danger. The high system voltage could likely be a significant do it yourself challenge for swaps.The higher system voltage is a interesting compare. Time will tell how these 900v systems age but certainly could entertain further potential weight reductions.
I recall earlier mod S with gearboxes developing noise and many being replaced. Not sure what the issue was. May have been some bad material, design, or build quality, but they took care of all of the problem units to my knowledge. They were the standard dual reduction stepped spur gear setup much as they look now but not built as robust. I believe they upped the bearings.Do you mean the early 2 speed Tesla gearboxes?
Agree, but after seeing his reporting come true time and time again, it is worth at least a listen IMO if your interested or invested. They have inventory of finished cars at the moment so we can confirm that. Confidential insiders sharing large number of order cancelations is the main take away from it for me. The service issues also have been reported by more than a few owners. Brian and Herbert did a point by point yesterday with much more detail, but still leaves you wondering a bit.I had a really hard time listening to that video. Lots of words but nothing shared as proof or even a reference
