OOS - Lucid Gravity Production model review

[Sid432]

Please use this thread to post all the gravity reviews. OOS just posted this few minutes ago and plenty more to come over the next two days

Why would you want all reviews in this thread? Personally I'd rather see new review in a new thread for discoverability (not needing to constantly revisit 1 old thread) and so the merits or critique of an individual review could be discussed without confusion.

Typical long Kyle video but here are some highlights

• Most exciting car launching in 2025
• Nothing charges faster in the US
• First Plug n Charge Car on Tesla Supercharger Network with Native NACS
• 80 AMP Charging for 19.2kW home charging with adjustable amperage
• Charged 10% to 80% faster than a Model 3 even with the 225kW limitation on the Supercharger network
• Has the first 1000V CCS to NACS adaptor on the market
• 100W USB C ports in front, 45W in 2nd row & 20W in 3rd row
• Matrix headlights with adaptive driving beam

Loving the improvements to the route planning and being able to set your arrival % at charger or destination. Lucid truly has taken on a lot of the feedback owners were asking for and implemented in the Gravity. The only thing that still seemed a little wonky is the connectivity with AT&T. I really wish automakers just gave owners the ability to allow the car to hotspot using peoples phones. They wouldn't need to worry about 4G,5G & beyond chipsets becoming outdated in the car with this method either.

Kyle also mentioned 150kW at 75% SoC which is pretty good.
It should be noted that the 10-80% comparison was with the crappy LG battery, the Model 3 with the Panasonic batteries are better.

Wow. Simply WOW!

Once again, Conner said what he said in the earlier test drive review: that per Derek Jenkins, the wheel diameters were staggered for cosmetic reasons, not handling reasons (at 16:50).

This is by far my least favorite part of the design. I do appreciate that they're not lying about it though.

The chief engineer I spoke with face to face was adamant the different diameter wheels were functional and told me not to even try to even it out with straight 22s.

The front is meant to be softer than the rear.

I don't mind the look -- kinda like it, actually. But it really narrows the choice of alternate tires.

Then that means the Eric Bach and Derek Jenkins do not have a meeting of the minds over this issue (or that Conner misunderstood what Jenkins told him).

Even if it does confer some handling advantage, which it well might, I seriously doubt that putting the same diameter wheel on the rear as the front would become a safety issue as implied by the phrase "not even to try".

Well, the car is tuned for the diameters of the tires. At the very least it would screw up the stability control system.

I wasn’t planning to change diameter, just wheel size. Tires can be adjusted, example:

265 45 21 will move to 265 40 22 and might be happy with 285 40 22 (stock size).

These statements are likely both true. The initial decision was made for cosmetic reasons, ie they could make it handle well either way at the design stage. But once they have picked their strategy and designed around it you can’t go back. As I’ve said before, the ABS and other sensors are now looking for the the difference in rare of wheel rotation to calculate slip, so screw with OD and you’ll throw everything off. And stick with the same OD but change the ID and you’ll get much more slip angle at the rear.

Not true.

It’s absolutely a safety issue if you want ABS and stability control to work as designed. Could I design a tire package that could work well? Probably, though it would likely involve mixing and matching tire types and possibly even brands. Would that be dumb and high risk for most situations, particularly outside of competition? Absolutely. When the Chief Engineer tells you “do not even try” thinking you know better, particularly as a non-engineer, is simply foolish. I’ve tried to give you guys a 101 here…

Of course the suspension is tuned for the different diameters. But that is different from saying different diameters were necessary to attain handling prowess.

My Air Dream Performance has 21" wheels front and rear, and Lucid seems to have had no trouble tuning its suspension to near perfection. The Porsche Cayenne Turbo GT and the Lamborghini Urus -- two vehicles that Lucid benchmarked against -- have the same front and rear diameters.

It sounds as if the Lucid design team might have pushed for staggered diameters for styling reasons, and the suspension engineering team worked their magic from there.

I think you misunderstand me. I have no intention of switching to same-diameter wheels on the Gravity for all the reasons you have explained here and elsewhere. And your arguments convinced me to switch to the largest wheels as I want to optimize the Gravity Dream for dynamic performance using the tires Lucid chose.

My question has always been about the initial decision to use staggered diameters in the first place.

If the Gravity and all its systems are so finely tuned to specific tires on specific wheels that nothing should be tampered with, that means that people who opt for the largest wheels should never drive their Gravities in temperatures below 45 degrees unless they also change the wheels as well as the tires (and can easily call up a different tuning program in the software), and it means that people who opted for the smaller two wheel packages should never attempt to put more performance-oriented rubber on their cars in summer unless they go to the larger wheels.

I just find that an odd design decision for an SUV as opposed to, say, a sports sedan or sports car.

We are in agreement.

Excellent point.
The "Photos/Videos/Reviews sub-forum is sufficient for having a seperate for different videos.
Wouldn't make sense to look for a Savage Geese review in this thread that has OOS in the title.

 

[msaunders9430]

Loved the review!
Based on most of the viewer comments, people have been waiting (just like us) and are really excited.
My concerns about software are, for the most part addressed.

HUD functionality should be covered in another video.
Looking forward to additional videos from OoS and others.

It looks so good slammed. That alone makes me want the bigger wheel package.

Giving up range vs looking great while hard parked. Serious debate.

Will be equally slammed on 20s too, just more tire less wheel
