Miles/Kwh

80 mph will hit you range a LOT harder than 70, for sure!

No doubt. But, how can you hold it back! It's fun to drive and comfortable. Can you ask much more other than trying to get somewhere faster?

Has there been any hints or rumors of Lucid implementing a proper lifetime accounting of efficiency and charging data?

It dawns on me that most people's (including mine) "lifetime" efficiency postings are based on the trip data, which seems to ignore at least some forms of power output (ie, when when you reset a trip meter the same moment you stop charging or unplug) the trip efficiency always shows higher than the "since last charge" calculations.

For me, it makes me not necessarily trust my mental calculations of how much range I'll realistically get from a particular charge on long trip or on a day where I have unexpected driving.

Obviously I can't base it on the EPA estimates, which I've never even come close to hitting, but I don't feel like I can really trust my lifetime trip meter that shows 3.22m/kWh because that doesn't seem to take into account A/C or other various aspects of per usage over the long term.

Even the since last charge says seems to be wildly inaccurate until I've driven at least 10 miles or so, as if the initial calculations after unplugging don't always start at the same baseline. For example, I work from home but make same short (~5 mile) round trips to lunch and back several times a week. On days with similar temperature, weather, traffic patterns, and diving style on my part, one days I'll get home with it showing 2.5-ish m/kWh, and other days I'll get home with it showing 3.8m/kWh.

As a result, I have to try to remember the rough efficiency only from after I've driven longer between charges, which I guestimate to be around 2.8ish.


I more cynical part of my brain wonders if that's one of the reasons a Lucid hasn't implemented a proper lifetime efficiency output for the user, because it would appear significantly less efficient than just keeping one of the A/B trip-meters un-reset.

Summer low 4’s. Winter low 3’s. It depends greatly on ambient temps and driving style and technique. Easy to get 4.5 if you try.

As far as I know what isn't counted in trip data is energy used while not moving. It does still count A/C usage and other peripherals, just not while parked. "Since last charge" includes everything, which is why you can watch it drop if you're pre-conditioning (A/C) your car before a drive. I think why you notice it fluctuating so much on short drives is: the A/C is doing extra work when you first get in, the battery isn't at optimal temperature yet, you're probably doing a lot of stopping and starting as you get out of your neighborhood, etc.

I record efficiency metrics with Home Assistant as well, looking at the raw drop in battery kWh in comparison to the odometer (reported in very accurate fractional miles). It does line up with the data Lucid shows.

I’ve had my LAGT with 21” wheels for about a month now and have added about 1000 miles for a total of 4.6K. Temperatures warm to hot in Florida now and am averaging 3.22 m/kwh combination city a some highway. When traveling on B roads about 70 mile one way trips at average 65mph, getting 3.65 m/kwh. Drove 200 highway miles at 75mph and dropped to granny speed of 70mph for another 150 mph and averaged 3.68 m/kWh.

Just curious: what was your efficiency during the 75MPH leg of that trip?

I’ve owned (and driven the heck out of) Ferraris, so I am no stranger to driving cars very aggressively. For whatever reason my AGT does not “speak to me” that way.

I am finding this myself for some reason. I've only driven about 50 miles, and I have hammered it a couple times, but it doesn't encourage me to hammer it through the corners. Perhaps that will come with time as i get used to the soul of the car.
