I thought this problem was solved a long time ago with time of flight measurement?

Well it's certainly not "compromise nothing". lol. I would be annoyed if I needed the charge and I was forced to pay for electricity at a fast charger. I agree with you that it's not the batteries creating the heat. It's probably that they're running coolant through the AC/DC and the battery...

But which coolant loop is the AC/DC (aka wunderbox) on? If it's shared with the battery that could explain it. Also, maybe they don't run the heat pump during L2 charging to save energy. I think even if they're not on the same loop they could be configuring it to use the battery as a thermal mass.

Have you tried driving the car with the spare on? Seems like the stability control software might be very unhappy about wheel speed being so far off.

Off roading is fun. There are lots of roads in Death Valley National Park where you could take a Rivian but not a Gravity. Though I just looked for YouTube videos and all I see are people softroading them... What often happens with off-road capable vehicles is that the second owner actually uses...

True, but what's the point of conserving capacity if you never use it? If using the 5%-15% is 3 times worse than 45%-55% but you only use it on road trips it's not going to make much difference.

Look up the lemon law in your state. In California a car is a lemon if it's been in the shop 30 days in the first 18 months.

There's a guy on the Tesla forum that's always posting about this and he's convinced me that the thing that really matters is only charging to 55% for normal daily driving (note that Lucid themselves recommend 50% charge for "storage") https://teslamotorsclub.com/tmc/posts/8851576/ From this...

That 341mi result was at 95 percent charge (who tests like that???) They also say the "average speed" was 70mph which is always going to be less efficient than actually going 70mph. In their most recent test Out of Spec got 376mi to dead. I'm just going by current available test results, on...

It does have a major problem that charging performance is reduced when HVAC is running (which is what OOS does in their 10% challenge.) Supposedly they've improved this in an OTA update. Without HVAC running it does add energy faster than the Gravity but probably not enough to offset the lower...

Though not quite as bad because the engine itself gets more efficient at higher loads.

How many Air owners set the cruise control for 70mph on straight flat Interstate? Internet says 18% less drag in Denver, that is a huge difference.

The thing to keep in mind about the Out of Spec videos is they drive until the car stops moving and they're done at 5000ft elevation where the air is thinner.

The Air is the most efficient large sedan. The Touring would likely be close to the RWD Model 3. It's interesting that the Model X is only 10% less efficient in OoS 70mph range test than the Model S. The problem with these tests is that wind and weather can make big difference.

I do on road trips. By far the biggest reason batteries degrade is calendar aging. Minimize the amount of time the battery spends above 55% and it will last a long time. The EQS SUV and the Rivian R1S Dual Max have slightly more range (in thinner Colorado air, really need them all side by...

Yes. From the EPA docs: The energy use per mile is proportional to F0+F1*mph+F2*mph^2. The F2 term will dominate at high speeds and it is only 3% different between wheel sizes. The F0 term and F2 term are equal at ~40mph so that's where aerodynamic losses begin to dominate. At 80mph the F2...

6kwh of reserve is not unusual. Teslas have 4.5% of reserve, so this only a little bit more. Lucid Air hits 0% at 482mi in OOS 70mph range test but didn't stop moving until 523mi, that's 8%, more than 6kWh.

Lucid should buy one of these: https://www.heina.net/product/tumble-tester-ii/?utm_source=chatgpt.com

My point was that if you go up a gentle slope for 100mi and return to your starting point the efficiency is almost exactly the same as driving on a flat road 100 miles and back. The elevation makes almost no difference to your total trip efficiency. If the trip were hilly enough to need regen...

I bet driving at a constant speed uphill and then back downhill would not degrade range much at all. As long as the hill isn't steep enough to use regen. Going up also gives the advantage of thinner air.
