The I-90 Surge by Out of Spec Studios

Also, clearly the Taycan is the best suited car for this type of race. For an actual cross country trip I think everyone would choose the Lucid if they had the choice for its combination of comfort, efficiency, and charging, but for this particular type of race it just doesn’t have the right kind of charging curve.

I’ve watched a ton of OOS vids and I think that if winning this race was a priority at Lucid they would prioritize matching the flat curve of the Taycan but after several years where the Lucid loses out because of the curve it just doesn’t seem to be a priority for whatever reason.

@Shane_SLC have you monitored a charge curve for 2025 GT at all while you had the car? I’m curious if it at least has the charge performance of the DE/GTP now. It’s a 118kwh battery now right?

From watching and snippets of the charge at various points, the charging curve appears similar but slightly lower than the GT-P and DE. 145-155kWh vs ~135kWh during the flattening period.

Check out Out of Spec's data. I think their curve was similar to what we saw.

Mainly because no one travels like this. Like was previously mentioned, the comfort of the Lucid wins 10/10 times for normal road tripping. Why adjust the curve for edge cases?

Should have probably included a Nissan Versa just to get the lowest price ICE.

@Shane_SLC thank you for doing your personal video. I thought your “failed the idiot check” line was quite funny as it reminded me of “failed your intelligence save roll”.

I was curious if the drop in efficiency in the 2nd leg was a result of thermal derating, or the terrain? (sorry if you explained and I just missed it)

I think that spreadsheet really illustrates that for a “days” drive (10-12 hours then stop at hotel and sleep) the range of the Lucid is incredibly useful to have so one can really choose the chargers one wants to use.

I think you previously said you commute using your Air, correct? If so, what is the efficiency you normally average at?
(Anyone else who wants to chime in on this I would appreciate it as I am curious)

Haha, I really like that! I definitely felt like I was rolling 1's here.

I think we were getting poor efficiency through Indiana and New York due to the weather. There was a bit of rain and a headwind that was pushing against us, and we were still trying to maintain maximum speed.

I absolutely agree. Especially on the first half of the trip we were able skip a lot of chargers than many of the other teams had no choice but to use, which helped us stay ahead of that pack for quite a while. If we did this route again and had each team only drive for 10-12 hours each day and then charge overnight the Lucid would do significantly better.

I drive a Touring with 20" wheels, and I typically drive 10+ mph over the speed limit, so my efficiency on my daily commute is typically between 3.2 and 3.4 mi/kWh. If I take it easy and conditions are favorable I can possibly see mid to high 3's. My lifetime efficiency is 3.0, but that includes lots of canyon carving, high speeds, and a few track days which really reduce efficiency.

Here's the link to our discussions from last night. My sincere apologies for the connection issues on my side. I'll be recording my own video and sharing it later this week to make up for my lack of input. Please let me know what your thoughts on the podcast video are and if there's anything else I can bring up in my personal video.

It's great seeing the spread sheet and of course my eyes fell right to the Ohio and NY charging sessions where I see the charging mimics the peak kW my 22 AGT sees when I drop to less than 10-15% battery, but then I look at your western states charging and Butte and Billings in particular, Butte with 2% arrival, peak 319 kW, 70.8 KWh added in 21 minutes for an average of 3.37 kW added per minute, and Billings with 0% arrival, peak 318 kW, 88 KWh added in 30 minutes for an average of 2.93 kW added per minute.
Mishawawka kicks ass with an 11% arrival, peak 329 kW, 69.6 KWh added in 19 minutes for an average of 3.66 kW added per minute.
If you guys do this again I think it would be interesting data for the ambient temperature to be noted when you arrive at the charging stations.

I think you guys gave a great effort, and I love the deep dive on you guys did discussing the events of the trip. I know the Fredonia/Altamont trip wasn't funny at the time but I gotta tell you it had me chuckling listening to the team discussing the events during that time.

If you guys do this again and are looking to get a used AGT with some battery degradation, I might be interested if the timing is right and if I still own the car.

I wouldn't say this race was anything close to real-life usage scenario at all, but that may just be me.

Races and adventure trips are never close to real-life, it's all about a challenge and having fun while doing so, having a heated moment or two , and being able to say afterwards "fuck yeah we did it!!"

That is so awesome you were part of this Shane! Watched the whole thing each weekend!
