Lucid Gravity GT efficiency

[yhinner]

Hi all,

I just got my 2027 Lucid Gravity GT. It’s been amazing, but I have a question for the efficiency and wonder if anything I can do to improve it.

I got my car 2 weeks ago, and I’ve driven for around 500 miles. On my way driving from service center after delivery it showed the efficiency was ~ 3.30 miles/kwh. However, it’s been consistently dropping during my daily routine round trip between home and office for first week. Now it is steady at around 2.8. I tried everything I can to prevent, eg. Turning on energy saver mode etc. No luck at all. My routine drive is around 14miles on-way, around 5 miles on highway, rest is local.

I’ve been navigating through the forums and seeing most people getting 3+ or even 3.4 sometimes. Is my experience normal, or is there anything I am doing wrong? It’s always Smooth mode, with High regen, standard suspension, though it auto-adjust to low on highway. The wheel is 20”/21”. I have the temperature set to 68F. I am in Pacific Northwest and outside temperature is around 55F. I always connect to Apple CarPlay and play music during drive. And I use builtin Maps for navigation. I am the only one in the car during my routine drive.

I also have a service appointment in couple of weeks to fix something unrelated, should I bring up this as well? Thanks!

I remember service centers advising new owners to wait to reach 2k+ miles to start measuring efficiency. Yours seems to see a bit lower than the rest, but not too much based on what I see on Lucidtracker. I get around 3 driving under similar conditions in the NE

Concur with you are advised by Lucid to go thru 2k miles before the system will start getting you more correct numbers. You are doing about everything you can tho for efficiency it looks like.

Thank you @prgarg and @9point81 ! That makes sense, I did not hear about the 2k mile calibration from the delivery advisor. Were your experiences also similar that it started with relatively lower, and after 2k miles the reading starts to go up to 3+?

From my side, I also measured by how much energy consumed during my trip, ie. around 27miles round trip, my battery consumed 7-8% of battery, so the midpoint efficiency is ~2.9. This aligns with the reading. Do you think after 2k miles it will start to improve? Thanks!

I didn't notice a change after 2k miles. I managed 3.1 mi/kWh on our first road trip, 3.0 on the last with 4k miles on the car, and I average about 2.9mi/kWh in mixed driving with a lot of stop and go and short trips.

Stop and go driving, lots of short trips where the car spends its energy coming up to temperature, and high speed freeway driving all cut into efficiency.

Be sure the tires are at least 42 psi cold (first thing in the morning). Mine and many others were delivered with 45 psi. I'm waiting to see how the tires wear and may increase to 45. Most cars do better with higher than recommended pressure without hurting handling or wear, just harsher ride.

I don't see the point of High regen. If anything Standard regen is already too high. Just as when accelerating, decelerating hard wastes energy in losses in the wiring and motors ect. As long as you don't need to hit the brakes to slow down Standard regen is enough.

Short trips don't help economy as others have mentioned. Just the tires alone influence this. On my Gravity the 42 psi rises to about 45 psi within 5 miles of city driving. That means the cold hard rubber heats up through internal friction to raise the tire pressure. Friction drops dramatically when the tire is warm and explains why the temperature doesn't keep rising indefinitely.

You don't say where you are at. If you are in an area that is already seeing cooler temperatures, that could easily explain the difference... especially factoring in relatively short trips.

It's Pacific NW I believe

Same, I didn't notice any difference after 2k miles.
Also same experience with stop and go local traffic vs longer road trip like drives. Efficiency improves in those, specially when engaging DDP2.
