Average mi/kwh

I just love that coming down a mountain in upstate NY I started with 301 mi range and ended with 311 mi range thanks to regen. I’ll report back the full trip later but so far averaging 3.5 mi/kWh on 19” Air GT with lots of elevation changes 75-90 degree weather, no ACC and paying zero attention to range preserving techniques mostly in Swift mode. If I tried to drive like grandma I’d go over 4 mi/kWh super easy in this car.
 
My biggest concern has been range with a subset of available EA fast chargers (I want to be able to occasionally top off with a fast charge as I only have a 20 amp dedicated charging circuit in my garage). The Lucid numbers I am seeing here are very promising on range. I think time will help on the subset (currently the closest EA fast charger is four miles away from me and after that...a long way).

It will help...at least for now...that the local power company is shrinking the "do not use" window from 3-8 to 4-7. That will give me more time to charge at home with my limited circuit.

The best part is that the excess range of the car gives you plenty of options. I had planned to stop at an EA charger on the way out but my 14 month old was asleep and if you don’t want to open up the pits of hell it’s best to leave her asleep, so we just kept driving till she woke up and then found an EVGo charger instead. If I was in a Taycan I would have been screwed.
 
Anyone knows if there is a way to see SOC vs time graph since the last charge on the car - maybe the app?
 
94% to 34% would be 67.2kwh. If the trip meter is saying 64kwh, it seems like the trip meter is using only energy supplied to the motors....
Another interesting note is that after leaving the car sit overnight in the garage, the SOC was back up to 37% making the kWhr consumed match the SOC.That actually boosted the efficiency from last charge but did not change the efficiency on the trip display. Definitely something not right with the calculations but I do like the miracle of adding to the SOC overnight without plugging in.

Looks like Lucid solvedthe energy crisis. Quick go buy stock!

I guess that this is like what happens on a golf course with me on the GPS. On certain holes they activate the GPS so one can see the location of the carts in front of your group. It seems that I see the carts drive away but the GPS doesn't update until a minute or so later. Your SOC overnight may have been a similar case of the computer having to catch up on its calculations.
 
Last night we had to drive a guest from Naples to Ft. Lauderdale to catch a 5:10 a.m. flight, meaning we left the house at 2:00 a.m. This created the best opportunity we've had yet to test range in optimal conditions.

Except for less than two miles, the roads from our house to the airport were all four lanes or wider. With no traffic on the roads, we were able to drive ~70 miles an hour on surface streets and then set the cruise control at 80 (an actual 78 mph per gps radar and roadside radar stations) for the long haul across Alligator Alley (Interstate 75) with almost no slow-downs or lane shifts required. It was a dry night with temperatures between 74-76 the entire trip. We had three adults and a small carry-on in the car on the way over and two adults on the way back.

We charged up to 91% and had 28% charge remaining at the end of our 215-mile round trip. The "distance since last charge" display showed an average m/kWh of 2.8. My own calculations showed 2.89.

The bad news is that we will never see anything like the EPA-rated range of our Dream Performance -- 3.9 m/kWh -- in even the best conditions when traveling at the national average interstate speed of 78 mph (per DOT studies). The good news is that we made the round trip without recharging with plenty of room to spare, which is something we could not have done in either of the Teslas we've owned, including our 2021 Model S Plaid. On the other hand, there were 4 Tesla Supercharging stations along or near our route, while there was only 1 Electrify America station that would have taken us on a 15-mile round trip detour to reach.

And back to the other hand: we were in a quieter, better riding, far roomier, and more comfortable car.

Edmund's and InsideEVs both got close and did not do anything crazy special. Why can't we? Until Lucid fixes and confirms the car is calculating and displaying the correct SOC and power consumed values, I plan to not worry about it.

Speed dramatically effects range. Also, you did not say whether or not the air conditioner was in use, which also contributes to range loss.

There Range loss at 78 mph vs 68 mph would approximate 15% on most vehicles.

Also, based on this article, at 70mph, the results were close to expectation:

The big variables are that Edmunds tries roughly to duplicate the mixed driving conditions assumed in the 5-cycle EPA testing, and Tom Moloughney does highway testing at 70 mph. My amateur "test" was highway driving at 78 mph, and higher speeds draw down range considerably.

I don't worry about range for local driving. To me, "real-world driving" means driving at the speeds I'm going to be driving on a long road trip. Yes, I could get closer to the EPA range rating by driving 70 mph on an Interstate highway. But I would also be driving significantly slower than prevailing traffic speeds, which studies have shown is more dangerous than driving at higher prevailing speeds.

We had the A/C set to 72 in nighttime conditions (no sunshine load) with exterior temperatures from 74-76. So the A/C was running under very light load. Both Edmunds and Moloughney set the climate controls to comfortable levels during their range tests.
 
Here is a chart from Car and Driver showing EPA estimated mileage versus their test at a steady 75 mp.

Given that we were driving at 78 mph, these figures pretty much square with what I experienced last night.
 
I saw another chart a few weeks back that showed EV’s are the most efficient at 25-35 mph. but who can drive that slow on a freeway? 😇
 
The real reason I was so interested in the drive last night is that we are planning our first long road trip in the Air for mid-June. As I prefer to use EA chargers over charge services of which I'm not a member, two legs of the trip will mean 211 miles and 222 miles between charges.

I also do not like to charge above 90% (especially at DC chargers which stress batteries more) or drop bellow 20%, so I wanted to see if we could do those two legs on 70% of the pack's capacity, understanding that the traffic and weather conditions probably won't be as optimal as they were last night. I'm now comfortable we can.

After those two legs, we begin to climb in elevation as we head into the Blue Ridge mountains, so I've planned shorter hauls between charges for that stage of the trip. Also, I'm the sort of road tripper who (along with my bladder) would prefer more frequent charging stops to the aggravations of hyper-miling.

Interesting. I did a 600 mile road trip this weekend in Air GT 19”, average mi/kWh was 3.6, temps were 80-90, with lots of elevation changes, speed around 75-80, three adults including myself, lots of luggage, plus my 14 month old in a car seat.
 
It would be interesting to see the range in Texas and AZ in the 100 Degree heat. EA’s lack of charging stations in Texas will take some adjusting unless people but the Tesla Tap to esnure they have a safety net while driving long distance like Dallas to South Padre Island. Dallas to Shreveport LA and back on a single charge (we could almost do it in my Suburban). At least I cannot live without AC in the Summer. On our ICE Cars it needs to always be at Max Cool. 🤓

Your car with those tires is EPA-rated at 4.5 m/kWh. You got 80% of that range.

My car with the 21" wheels is EPA-rated at 3.9/kWh. I got 74% of that range in better conditions.

I'm wondering if the "Dream P" version of the Air (I stayed in "Smooth" mode the whole trip) exacts more of a range penalty at highway speeds than do the other variants?
