Tips to Increase mi/kWh??

[byebyetesla]

Hello fellow Lucid owners!

I replaced my 2016 Tesla S with a 2023 Lucid AT a few months ago. There were a number of reasons driving this decision but one was the increased range. I have my first small road trip coming up and I'm seeing my mi/KWh in the low 3's which means maybe 300 mi range yet I'd seen estimated over 400 mi numbers during my research. I believe my battery is 92Kwh and I know how things can vary as I had a Tesla and had same experience but this is a significant difference! My first thinking is maybe there is a problem with my car so I wanted to ask what people are experiencing. Other than having the stock 19" wheels, psi around 50, using hard regen setting on smooth, no wind, no A/C, no excessive speeding on highway, what else are people experiencing and tips to increase this range? On my Tesla there was a 'Range Mode' setting that would shut off one of the 2 motors and alternate between fwd and rwd to reduce power but I don't see this as an option on my Lucid.

Any thoughts on other's experiences and tips is greatly appreciated! My warranty runs out in 9k miles so I definitely want to get this into service if there's a problem.

Thank you in advance!!!!

my experience in my air gt is that I don't try to get the max range from it. I drive 70-80 mph, usually below 75. I always have the hvac running and I use the lower regen setting which is really a moot point on longer interstate driving. my rule of thumb is to deduct about 20% of the range indicated. my air gt will show 505 or so miles at 100% SOC and from that point I will get 425+ miles of range on mild, no rainy days with minimal gradient changes. YMMV

When you say you've seen "estimated over 400mi numbers", where did these "estimations" come from? Are you referring to EPA numbers? The EPA rating of Lucid AT would be approx. 400 mi. It is unlikely you will get that in typical highway driving.

I have a 2022 AGT. My lifetime average is ~3.65mi/kWh on ~16,500 miles driven. On highway driving (say, I-10 @70-75 mph), my AGT might get ~350 mile range (100% SoC to 5-10% SoC). EPA rating is 510 miles range. But you won't get the EPA range unless you are driving at 65mph or slower. At 75mph highway cursing, Lucid Air typically gets ~70-75% of the EPA rated efficiency (see various owner posted metrics on this forum).

There has been a lot of discussions on EPA vs real-life efficiency/range in this forum. Short answer is, it is highly unlikely you will get the EPA range with the Lucid Air unless you are driving at 65mph or less. Some owners claim the 2025 Airs do better than the older Airs.

My AGT does not have the ability to disable part of the power train to conserve. In contrast, my (AWD) Rivian R1S can cruise only on FWD on "Conserve" mode and yields approximately ~7.5% improvement in range. In general, the Rivian perform close to the rated EPA efficiency rating. Most German EVs also perform close to their posted EPA rating. Some even exceed their EPA rating. Tessla and Lucid have more deviations (from EPA rating) than other EVs.

I have a 2023 AT with 30k miles and 19s. I am just back from a road trip and I got almost 4mi/kWh on non-rainy day. I drove 270 miles yesterday using just 80% of my charge which suggests a full range of 340-350 miles. All I did was ACC at 75-80mph and mostly stayed in right lane. I know some people here will call me lame for driving a Lucid in right lane, but I will take that any day than an additional charge stop. It is a net time-saver.
P.S: HA integration tells me that my battery is at 94.5% health and only has 84kWh capacity. So at full capacity, I would have gotten 370mi range which is effing great!

This is the wrong part here. Don't try to predict road trip range from non-road trip range. Local driving efficiency is much lower than long distance highway efficiency. I personally average in the low 3s as well, but easily see 4.0+ on a long drive.

You see lower efficiency with city driving and higher efficiency with highway driving? I have the opposite trend. My AGT (20in with aero covers removed) often sees around 3.8 mi/kWh in the city, and 3.3 mi/kWh on the highway (5-hour interstate trips at 75mph). Smooth mode, High regen. On colder days (sub-50F), I'd regularly see 2.9 mi/kWh on the highway.

To respond to OP... I've heard from Lucid Service that Drive Assist/Adaptive Cruise is more effective at maintaining a speed than one's foot on the accelerator, so you can reduce power fluctuations by using those systems. I'm not sure if you have the Glass Roof, but its additional weight could be a factor as well.

Depends on a lot of things as usual, I guess. I think most of us see lower efficiency (compared to up to about 75 mph on the highway) in city driving due to all the stopping and starting. I would've thought your heavier GT would be even worse in the city than my Touring. Also as you said ACC should be more efficient on the freeway and I do generally use that on longer trips. It won't be better if you keep getting stuck behind someone, slowing down, then accelerating to pass them though. You'd want to actively lane change before the ACC slows for a car in front of you.

Well the stopping is what gives me that boost in efficiency. I can watch the mi/kWh climb while regen slows me down in a city environment, and then accelerate grandma-style if I want to keep the numbers up. On an interstate, I don't have those opportunities.

Your mention of weight got me wondering... does the GT's heavier platform (and higher momentum) equate to greater recuperated energy? If a Touring and GT were driving the same speed, set to the same Regen Mode, and released the accelerator at the same time, which would roll further? If the GT, this would suggest a GT driver can start their regen earlier while approaching a stop, thus capturing more energy. Or perhaps Lucid has tuned the regen system to produce identical distances, so even a Pure vs Sapphire will have the same non-friction stopping experience.

Maybe someone has done a video on this.

Stopping doesn't improve your efficiency, that's not physically possible. Stopping with regen braking is more efficient than stopping with friction brakes, but it's not more efficient than not stopping at all (assuming you accelerate again after stopping), because except in a perfect vacuum with perfectly efficient technology, accelerating uses (significantly) more power than regen can capture.

In other words, going 10 miles at with 10 stops will use more energy than going 10 miles at the same speed with 0 stops. So, if your local efficiency is higher than your highway efficiency it must be almost entirely due to the change in air resistance at different speeds.

does the GT's heavier platform (and higher momentum) equate to greater recuperated energy? If a Touring and GT were driving the same speed, set to the same Regen Mode, and released the accelerator at the same time, which would roll further?

In theory yes, the GT has more kinetic energy than a Touring at the same speed for regen to take advantage of. Additionally, the GT's larger (and thus higher voltage) battery can charge slightly faster than the Touring's. I think the GT's motors may also have more windings, resulting in more power generated per rotation - less sure on that one. In practice I have no idea how these things add up in the presence of other limitations (e.g. is regen limited by the Wunderbox before those other factors come into play?)
Interesting question! Somebody should test it!

This mirrors my Touring experience. Recently drove from the Bay Area to Palm Springs, easily got 4.1 at arrival, though a lot of that was driving 73 mph on I-5. Around town low 3's (can easily get 30 miles at 6.21, but by the time I climb the hills to get back home it's barely 3).

Right, of course. I guess what I was getting at is the additional air resistance encountered at highway speeds can have enough of an impact to display a lower efficiency over a several-hour drive... versus a handful of city trips which can display a higher efficiency thanks to regen and low drag. When you take the total miles traveled into account, what you're saying is surely correct. My scenario comparison is flawed because the highway trip is 350 miles and the couple of city trips are 40 cumulative miles (for example).

The HVAC uses 0.75 KW/hr on it's own on fairly low, so try to use ventilated seats and raise the temp a bit. The HVAC will cycle on less that way once the car achieves the target temperature. It uses something like 3kw to just bring the temperature in the cabin from 95 down to 70ish, so can also use the windows and fan to push hot air out first. I can watch the car's mile per charge go up and down when it's charging by just turning the HVAC on and off. Otherwise I use ACC even in city driving with High regen on Smooth; since I find it hard to keep the speed slow at 50 mph streets.

I got 5.16 miles/kwh and a friend got 6.25 miles/kwh short trip in 2025 AT 20 inches in 108F day with AC on at 60 miles/h
