How Much Range Are You Actually Getting?

[milgauss]

Especially with wind. Due to a square-law loss of range with airspeed, a headwind hurts more than a tailwind helps. Crosswinds reduce range too.

The point that keeps getting lost here is that I believe if my previous Model S was driving next to me on that same trip, the Tesla would have had the same or better 3.1 mi/kWh-- likely better since its lifetime average was 3.4. Based on their EPAs alone, the Lucid should be 20% better than the Model S.

Now of course I can't prove that, but I rarely saw below 3.4 or 3.5 on road trips with the Model S. And, it's lifetime average of 3.4 reflects that when almost all it's mileage was city and stop and go freeway.

Don't shoot me if this is wrong, but I seem to remember it from someplace. Is it true that Tesla gives a number that only includes the power used to actually drive the car and not all of the other subsystems whereas Lucid gives a total number? It might account for some of the difference if true. I could also be dead wrong on that as I have never owned an EV before and I have no real first hand knowledge about Tesla. It would be great if someone that actually knows these details can confirm or debunk this.

That would definitely be interesting if true! (And not shocking given Tesla's marketing spin to everything.)

This was my understanding as well as to why the data is skewed and people were saying that Tesla was +90% in charging efficiency as well

Honestly at 75mph in 50 degree weather with a bit of wind I would think 74% of EPA is ok. I imagine that other EVs would see a pretty similar result in the same conditions.

Honestly this guy got all most 100% of range in 50 degrees doing 70 miles an hour.

My car experiences between 8- 10 miles of range loss per 24 hour period without charge.

True, but it also warmed up to low 70s and he BARELY had an elevation change of 110 feet? I think he said?

That's way too high, it should really be in the range on 2-4 and recently mine was less than 2 per 24 hour period. Keep your keys/phones away from the car!

I'm still with you that I think something is fundamentally wrong. It could even be that their calculation displays are bugged. I really hope there is away from Lucid to be able to definitely tell by pulling data.

Yea, if you feel it's incorrect, e-mail customer service and they will pull the data and then maybe bring your car in like... @Bill B ??

 

[Bill B]

I guess the main concern is seeing the Lucid have worse mi/kWh than my previous Model S(s) driving in the exact same conditions when their EPAs suggest the Lucid should be considerably better than the Model S.

I hope they find the problem and send out an update. My car has something using energy in the background some days and others not which reduces the range by 40%

Yea but like @CLTGT stated, the Tesla energy consumption is ONLY for driving the motors whereas the Lucid uses total energy consumed to move the car

Good information I did not know that. Thank you thank you for that.

 

[hydbob]

Ye

Yep, exactly like how for the longest time, Tesla would only show energy delivered INTO the batteries and not the total energy used to charge up. It's only when they changed how billing worked that they started charging the customer for total energy used to charge.

But still, in anyone's situation if you feel something wrong, it's best to contact Lucid to pull data just to make sure everything is on the up and up.

Is it possible that the Lucid software is miscalculating the miles/kw and underestimating the range? Most of our complaints about range have come from estimates of range arrived by use of the stated mile/kw usage. Has anyone attempted to duplicate the range test used by Tom of InsideEvs that does not rely on mathematical estimates of range?

The best test I could have done was from 100% to 3%. I went 337 miles which put me at 74.7% of EPA on the DEP w/21".

Conditions that day was pouring rain for the first hour followed by mid 50s to mid 70s the rest of the trip. The car was also laden down with 2 adults and 2 kids including 2 car seats with 3 suitcases and a ice chest filled to the brim with food/drinks/ice. It was a real world as I could manage. When the roads were dry, I averaged high 70s. During the rain it was slower, probably high 60s mph. This was before ACC was available.

Interesting. We are opposties. My 2013 P85 shows lifetime 291, while my GT is averaging 3.8.

I took a scenic drive today with my daughter. (AGT, 19", windows halfway down the whole time, half highway speed, 45% 50-55, a few stops) Started out charged to 501 miles, ended at 374 having gone 114.4 miles. Averaged 4.2 mi/kwh. It was actually 4.4 until I had to go over the mountain at the end. Not too bad. I might try the same trip in reverse next time to see what happens. Also, my strong regen was not working. I was only getting standard on the high setting. I'm hoping a reboot will fix that.

 

[milgauss]

I don't understand the Edmund's data:

If the EPA is 27 kWh/100 mi with a range of 520 miles, that would require a 140.4 kWh battery.

Edmund's test showed 28.3 kWh/100 mi which would need a 143 kWh battery to get 505 total miles.

Not sure how a 118 kWh battery delivers 140+ kWh?
