5.0 miles/kWh: Say Hello to the World's Most Efficient Car

[joec]

I recently took a trip to the NC mountains and on my return trip down the mountains I achieved what i thought was incredible mileage. I charged up and during the trip down the mountains, I went 37miles using only 3 kwh, or 12.3 miles/kwh. Also, for nearly 30 miles the trip meter did not register any kwh consumption and I actually increase SOC from 88% at initial charge to 90%. The issue I experience is that the trip meter never registered higher than 6.1m/kwh. Huh? Is 6.1 kwh/m the maximum amount on the trip meter? Hs anyone experienced anything like this? Feedback is welcomed.

Yes. The meter will never read above 6.1. Quirk in the software that's been there from the beginning.

That’s the highest it goes.

Bummer. The computer can't deal with a simple arithmetic calculation? Don't see the point of the limitation. I think it would be cool to see how high the mileage can go in various driving conditions.

Lucid is not very good at math.

i've never gotten better than 3.9.

City driving: 3.9
All highway from NYC to NC: 3.9

not sure how people are getting 5+

There have been many, many posts and thread about this subject. There are many factors that affect it and the biggest one is your speed.

Saw this post on Reddit. An AGT ran for 749 miles on a single charge in Europe! Is 6.69 m/kwh real?

Downhill?

 

[SoCal_AirTouring]

Downhill?

It says the route went thru Switzerland, Austria, and Germany. It's surely a mix of uphill and downhill.

 

[marsarbu]

It says they Switzerland, Austria, act Germany. It's surely a mix of uphill and downhill.

I'm pretty sure there's a lot of downhill overall. I have a hard time believing they could have achieved this on a flat surface. Full disclosure: I haven't watched the video.

The net change from point to point is about -4200ft. Over 749 miles, that's just an average -0.1% grade. Given the area I think there's practically no way they didn't have a few mountain passes along the way. It must've been pretty low speed though.

 

[Pragmatic]

Well 4200 ft would be a little over 8 kw-hr.

 

[illopp00]

Pretty easy to do if you average 37 mph, I don't even think that is the first time someone has tested an Air GT to hypermile it above 700 miles.

With the 4000+ft altitude drop and hypermile, I am not sure I see what's the big deal!

No matter what the route has consisted of and at what speeds the car has been driven, 749 miles on a single charge is a big deal.

It just broke a Guinness World Record so just accept it for what it is. If all and sundry think they can beat it under the same conditions then they know who to contact.

I just love how people won’t accept the record as a win but instead say “oh it’s downhill” or “oh it’s a slow speed”.

Has nothing to do with accepting or not, I am happy for them, be they Lucid or some other brand. It's just that it starts stupid conversations around the table, with "connoisseurs" rattling off about today's EV that can do 700 miles on a charge. A stunt for clicks w/o any relation to real life. Like Clarkson racing a Prius and an M3 to make a point that the Prius is not more efficient. At least that was fun to watch.

At least it raises Lucid's profile in Europe, which is a good thing. I'll take it.

This is not a legitimate "record" on EV efficiency as the circumstances convolute driving efficiency and elevation change without any quantification. As it stands, it is totally meaningless, hence the skepticisms by some of us.

As a comparison, in 2019, a Virgin Atlantic 787 set a "speed record" of 801mph over Pennsylvania. https://www.thetravel.com/jet-stream-propels-record-breaking-l-a-to-london-flight-to-801-mph/). 801mph would have broken the sound barrier, i.e., supersonic flight. The 787 was/is not capable of doing that without disintegrating! It was actually riding an unusually fast jet-stream flying at sub-sonic speeds (mph with respect to the jet stream) but, @801mph when references to the ground speed. Max speed for the 787 is ~Mach 0.9. In reality, no real performance benchmark was broken. Simply, it was a sleight-of-hand by quoting the exaggerated frame-of-reference (ground-speed vs air-speed). This is the stuff students should have learned in high school.

I think the aforementioned "record" for the Lucid range is bogus and misleading. It is good for a laugh, that's all!

It's not meaningless, nor is it a new or surprising thing - people have been doing distance records like this since we could count. It's not particularly useful, but it's no more meaningless than most world records. The point is not to tell the average Joe CarBuyer the range to expect from the car. The point is to make a headline and have people go "ooh. cool." And maybe "wait I thought EVs could only go 20 miles at 45mph? tell me more?" It has done that. Nobody's saying it is any more than that, so why does it seem like there's an argument now?

It is intentionally misleading when the frame-of-reference is not explicitly cited! "Oh, what a tangle wen we weaved...."
