If the EPA rating really is 442 miles (or better?), this means that the Lucid Air total system efficiency (powertrain and aerodynamics) is approximately 15% greater than the Tesla Model S.
It was only the "Long Range" version of the Model S that attained the 402-mile rating recently. However, assuming the Lucid the EPA tested was the twin-motor version, its performance is more in line with the "Performance" version of the Model S, which still has an EPA rating of 348 miles.
At the same time, the Tesla has a 100-kWh battery pack, and I'm assuming the Lucid has the 110-kWh pack that was reportedly used in the highway range tests earlier this year. So, given the different battery capacities, the better comparison of the Tesla to the Lucid is not actual range, but the efficiency metric of miles/kWh. Using that metric, the Lucid is yielding just over 4 miles/kWh in EPA testing, while the Tesla Performance Model S is yielding 3.48 miles/kWh . . . i. e., 15% better efficiency.
If so, this is a significant accomplishment for Lucid and, on top of the recent Cd test results, further support for the proposition that Lucid actually fulfills its claims about the car. I'm keeping my eyes peeled for the Tuesday announcement to see if they clarify the configuration of the car tested, such as battery pack size, number of motors, tire and wheel combos, etc.
