The data you cited are impressive. And I am NOT in any way saying Lucid's power train is not efficient, perhaps one of the most (if the most) amongst the popular EVs.
That said, according to controlled testing by multiple reviewers, Lucid and Tesla are the two worst cars when it comes to controlled tested range vs their claimed EPA range claims and the German car often met or exceed their claim. Most owners on this forum reports long-term cum efficiencies in the 3.4 to 3.7 miles/kWh. Thus, while Lucid might be the most efficient power train, but are they really as good as they claim in real-life driving. Yes, Lucid's might be the most efficient power train, but in real-life driving, it is not as efficient as they claimed to be. Both statements can be true at the same time. That, is my point!
When I place my order for my AGT in late 2021, I was travelling regularly between Phoenix and LA where my son went to school. The door-to-door distance was exactly 400 miles 9from my Paradise Valley house to my Rancho Palos Verdes house). Driving at 75mph, starting at 100% SoC, it was never able to make the trip without charging. Yes, I do know there are changes in elevations along the way. Phoenix is ~1,300ft above sea level and LA is almost sea level. And Yes, there is the Chiraco Summit (1,706 ft) in between. The AGT is rated at 516 miles (EPA). It has never been able to do the 400 mile run without stopping to charge once. I've done this under different weather conditions.
That said, I WILL SAY that Lucid is probably the most efficient power train, but in real life highway driving, it is significantly below (say 20-25% below) its claimed EPA range.
And YES, I do know the EPA range is an amalgamation of varied driving conditions and there are "fudge-factors" associated with it. Then look at the owners reported "life-time" efficiencies. And also ask the question why other manufactures (e.g., German cars) often met/exceed their EPA claims whilst Lucid/Tesla have significant negative deviations.
