And how many charging stops to drive it back the other way up the mountain?
One.
The dry weight of a Lucid Air Grand Touring is 2,360 kg. Add a couple of occupants at 80kg each then you're lifting 2,520kg up 1,300 meters. Gravitational potential energy e = ghm = 9.81 * 1300 * 2520 which comes out to just over 32.15 megajoules and very close to 9KWh. This is the baseline energy that is gained coming down hill and used going up hill. If we assume that the efficiency of the regeneration and the utilisation are about the same then you're going to gain less than this going down and use more than this going up, but the net difference is still going to be about 18KWh.
The nominal battery capacity of the Air Grand Touring is 112KWh, with the usable capacity probably several percent less, so you'll need about a 20% to 25% charge en route going back up the hill. Even if it's twice that, I don't think you're going to need to stop more than once.
