This was Friday, and I was charging to 90% because I was on the road trip. So, 62% of my battery in 41 minutes. The final 10% of the charge took about 15 of those minutes. No preconditioning. The charger was a split 350 so I was getting 175 max.I think it might depend on the model but apparently the ioniq 6 RWD can do 340 miles at 70mph. That gets you ~270 miles in 20 minutes.
In 20 minutes you can get maybe 50% on a GT which would get you approximately 200 miles. A pure or Touring would only get 150 miles in 20 minutes
Lucid software does tend to protect the battery from degradation so their charging curve is less aggressive than the one on the Hyundai/Kia.
