As we can see in the tweets, the Air Dream Edition with a 118 kWh battery was able to get up to 251 kW at a Electrify America fast charging station (the value fluctuated between 245 and 251 kW) at about one-fifth state-of-charge (SOC).
That's a pretty good result - not yet at
300 kW mentioned by Lucid - but we don't know the details - whether 300 kW is possible right away or if there will be a asoftware update, whether it's possible at Electrify America chargers, as the car has a 900 V battery system or whether the battery was preconditioned for maximum charging rate.
The app above shows remaining charging time of 1 hour and 25 minutes. We guess that this is the time to reach 100% SOC, which would suggest that the last percents will be replenished slowly. A full test is required to draw any real conclusions.
One of the images shows that during the session, the car received 80 kWh in 31 minutes and 2 seconds. That would be almost 155 kW on average, which is one of the best results on the market.
