Selfie cameras are flipped (like a mirror)

That just changes the maximum torque. They could get the same front torque with an 8.7:1 ratio. It would be interesting to see the efficiency map for Lucid's motors. As you said though electric motors are efficient over a wide range of RPM and load so it's probably a small difference.

If higher ratio is more efficient then why did they use 7:1 on the front?

Is there an issue with the motors overheating in low speed, high torque condition? Rivian does claim to have done the Rubicon trail in an R1S. I'd love to see a video of how they did it.

In a traditional SUV (with lockers) you can send all the torque to one wheel though. Kyle Conner was saying this limits the off-road performance somewhat and he'd like Rivian to put a physical locker on the quad motor. Obviously this only matters in pretty extreme rock crawling situations so...

It's a Grand Sports Tourer!

Definitely V3, I charge there all the time. Great Basin bakery and Mountain Rambler Brewery are great. I don't know about different V3 revisions. Never seen it more than half full.

All terrain tires are much less efficient than all season tires.

Gravity is 7:1 front 8.7:1 rear. Emad Dlala mentions it in the recent OoS video. A shorter gear ratio would be less efficient.

For example South Dakota has 9 V2 chargers and only one V3. If Tesla were motivated I bet they could upgrade the V2 chargers to support NACS but it's probably not worth the development cost.

I do all my own oil changes. I don't trust mechanics. I think it's been 20 years since I've had a mechanic work on a car. Not sure when I should change the gearbox oil in my Model 3...

NACS is just CCS with a Tesla connector. I think this is mostly because Tesla initially filled out the whole country with V2 superchargers. Many of those chargers hardly ever get used so they've never been upgraded to V3.

There are sidewall repair kits though I've never used one and I've heard you should probably carry an angle grinder and flappy wheel too to prep the sidewall. https://www.gluetread.com/ Regarding cell reception, iPhones and some android phones come with satellite texting capability. Still...

First experiment someone should do is see what happens if you swap a front and rear wheel. They really should have copied this feature when they were benchmarking the Pacifica (as far as I can tell no one makes a Vredstein space master spare with a 5x120 bolt pattern). I have one for my Model 3...

The biggest difference is the 22"/23" PZ5 is a summer tire so it will have WAY more traction than the other options. The downside is that if you drive somewhere where the temperature is below 40F you'll have to swap wheels. I bet ride quality will be similar for all the options.

Good question. There are V3 sites that are not NACS partner sites. For example my favorite charger in Bishop, CA is Tesla only. The other newer Supercharger in town is a "NACS partner" though. I'm not sure if the station would need to be upgraded or if they just want more people going to the...

I'm a huge fan of sidewalls too but the 22"/23" sidewalls aren't actually that small. The tires are gigantic, 30.4" diameter front 31" diameter rear. My Model 3 has 18" wheels with 26.3" tires so the 22"/23" Gravity actually has the same amount of sidewall. My main concern is cost, those tires...

Doubling the voltage actually quarters cable losses, loss is current^2*resistance. Makes me wonder if we'll eventually see voltages higher than 1000V. I guess those V2 cables were super efficient but man were they heavy (and probably much more expensive due to all that copper.)

The change in resistance with temperature is not nearly large enough to offset the 50% extra length of the V4 cable. It's basically proportional to degrees Kelvin for copper. My complaint is about the inefficiency of everyone having different charge port locations.

I just wish everyone standardized charge port locations. The V3 cable has a lighter feel and is more elegant than the longer V4 cable. One thing Kyle mentioned in a video is that the V3 cables may not be able to sustain the 20 minutes of 500 amp charging the Gravity is capable of. The cooling...
