Let's calibrate when we say Lucid are most efficient, fastest in charging (900V architecture) etc..
First, I agree the Lucid power train engineering is better than most (if not all) of their competitors. That said, in actual everyday usage of the product, does it offer the user tangible performance and cost-of-ownership gains over its competitors.
If you look at the recent Kyle Conner race from Maine to Florida-keys, over 2,000+ miles, 33+ hours of non-stop driving and multiple charging stops, the two Lucid Gravities won, and the Tesla was close behind. That said, in spite of Gravity's "compromise nothing" specs, (best efficiency, 900V charging, low drag, etc.) the Gravity's winning margin was only about 6-7% (elapsed time) over the next 3 EVs, including the R1S, which Kyle called a "brick" because of its inefficiency, poor aerodynamics, and 400V charging architecture. That said, no one is disputing the Gravity won. But, IMO, the "winning margin" was amazing narrow, and inconsequential to most mid-segment consumers.
Now, rationalize these findings in the context of the mid-market segment. Specs aside, @ $40,000-$55,000 price point, can Lucid deliver a profitable product that is price and performance competitive with other manufactures (Hyundai/Kia, Volvo, Rivian, Tesla, BMW, etc.). All of these Lucid competitors will be earlier to market with their mid-market offerings by 1 year or more. And all of these competitors have more extensive service networks than Lucid.
Yes, Lucid will likely have the best specs. But I think Lucid will have a rough time staking out a profitable foothold with its mid-market offering.
