QUESTION Review showing 4.06 miles per kWh with 2025 Air Grand Touring on the highway with 21 Inch Wheels going 73 MPH. Is this even possible!?

[WildRide47]

As I got older, and with traffic clogging roads everywhere, the competition turned from speed to efficiency. I get over 4mi/kWh on almost all road trips. As stated, you need to practice finesse and proactive driving with your right foot and vehicle mass.

How boring.

I’m in the camp of long drives, I’m ok going middle lane at 75 mph, but driving in LA for drives of 1.5 hrs or less (~60 miles), I go with speed of traffic in the faster lanes. My LT kWh is 3.06. ‘23 AGT 21” tires. And I’m OK with that charging from home when I need.

One more note, when I drove to OR from SoCal going 75 mph as average, I did 3.3 kWh with hills and valleys on a 1250 mile roundtrip.

I had a ‘22 AGT loaner with 19” wheels for two weeks earlier this year and found the range on that vastly inferior to my car…more on the order of 3.3 - 3.5 miles/kWh.

Yes! You got exactly what I was trying to get at @j4gates !

I baby the throttle pedal on acceleration and gently lift off for maximum regenerative charge on my AGT.P and cannot achieve the 4.06 even on the exact same wheels and in the similar area.

The Pure Loaner with 19 inch wheels I got while my vehicle is in the service center for a Drive System Error can easily achieve the 5.0 Miles per kWh see below assuming I am driving it like a grandma (Please see picture reference below taken last Friday). Trip A and B is an average I have been raising with my personal record vs other Vehicle Loaner drivers. See further below for the original readings on inception.)

2025 Air Pure on 19”, Smooth with High Regen, 70s on freeway, 50s on backroads and 35 in town, 13.5k miles (Last Charge figures are all backroad/in town):

It has become clear to me over the last several years of driving my Touring that there are waaaaayyy too many variables to try to make sense of comparing one person's vehicle/efficiency to another's. The screenshots of anything less than 100 miles since last charge are not particularly helpful as they represent such a small distance that terrain and speed differences can lead to irrelevant outcomes. When you consider temperature, wheel size, model, model year, topography, battery health and degradation, even wind speed and direction and then add on variability between drivers, it's damn near impossible to make accurate comparisons. I didn't feel like my car was particularly good or bad with range or efficiency. But it's significantly better now that I just had my battery replaced. As long as you are happy with what you've got, making inaccurate comparisons between cars isn't going to be beneficial. IMHO of course.

Not exactly answering the question, because this is a different trim and different wheel size. 2026 Lucid Air Pure, 19 inch Aeronaut wheels. A drive from Berkeley to Carmel, driving around Carmel a bit, and then down the Big Sur coast as far as McWay Falls and then back to Berkeley. A mixture of city driving, fast freeway driving, and twist-turn up-down California Highway One on the Big Sur coast. Fastest freeway sprint was about 75 mph, for a few miles when fairly heavy traffic allowed. 4.20 m/kwh for the trip. Thick segmented line at the top is number of drives within the overall trip, thin blue line is state of charge, yellow line is elevation changes.

49 psi cold inflated 19" factory A/S on Lucid wheels traveling at legal highway speeds without heat/AC and headwind
one can get very high mi / kWh numbers. EPA range with 118kWh battery and 19" hard rubber gets over 500 mi range. (GT and DE)

I am more than happy with the range of my 2022 GT.

my mi. / kWh remains at 3.3 mi/kWh after 4 years of ownership and swapping out wheels / tires every 6 months. ( 19" A/S to 21" summer.

I try to drive safely and economically, but the power is so corrupting of good intention...I confess I am weak

I know I could do better ... but I love fun.

LOL! You aren't alone. I have decades of safe, economical driving. It's in my blood. But... that POWER! I'm pretty sure that I, too, will not be able to resist!

Revisiting this after a long while. I notice that 2.11 Software / UX 3.0, has made things more consistent in real time efficiency reporting. I am at a static 3.16 Miles per kWh for my GTP with 21 inch summers over 12,000 miles.

I don't have a heavy foot, however I don't have a grandma foot either. Safety first and speed limits compliant, whenever possible at a stop light ; if I am first in line and the line of sight is safe and clear. I will teleport down the 1/10th in 2-3 seconds . The car can do a "1/8th in 6.278 seconds at 124.56 mph." This alone will reduce range by 1-2 miles which is equivalent to only driving the car with Ventilation for a short 2 mile start to stop destination surprisingly.

What increases or makes EPA efficiency achievable is long distance travel, the more you cruise at 70-73 MPH (68-71 True Miles GPS), you will start seeing your range creep closer to EPA 446/118 =3.77. The closest I hit to that was 3.69 from San Jose to Napa California right at the exit Ramp. Then it reduces from there when traversing on local roads.

This leads me to believe :

1. The Air does it's best efficiency on the move anywhere between 40-73 MPH.
2. The Air suffers from stop and go traffic and short stretches; I've seen as low as 2.22 miles per kWh for 2 miles of driving.
3. The all seasons have the most consistent miles per kWh performance if you want to be at the 4 miles / per kWh +.
   • However, they will still struggle on stop and go and city traffic especially the GT and Touring just due to the weight of the vehicle. The energy propelling 5-5.2k pounds from a dead stop is not negligible.
4. In Real world the 20 Inches are surprisingly close to the 19 inches on the touring with about a 0.2-0.3 kWh difference
   • I managed 3.6 mi/kWh on the summer 20 inch tires and 3.85 mi/kWh respectively for the 19 inch all seasons in mix driving over 1,000 in each car.
5. In the Pure with 19 inches I consistently got 4.2 miles pe kWh + in mixed driving and in which also got the least impact in stop and go had it for around 500 miles.

Really neat, what app is this? I'm hoping for more stats and efficiency after I upgrade my CCCv1

As stated above, it's very difficult to find insights on short drives or across changing environmental conditions. Aero drag is the biggest hwy factor, and power to negate drag rises with the CUBE of velocity. We could all exceed 6.21mi/kWh and 600 mi if we found a warm, empty, flat road, and set CC to 35mph. One tip for cold morning drives: charge until the moment you leave. Your battery and drivetrain will be warm, and experience fewer parasitic losses.
