Not sure what we classify as an SUV, but anything that is not a sedan, coupe, or truck is a SUV in my eyes. With that disclaimer aside, I have driven the EV6, Ioniq 5, and ID.4. Never had a chance to sit in an R1S, so I am not including it despite seeing reviews and one in person from the outside (massive vehicle). I have seen the Gravity in person at the LA Auto Show, so I feel I can speak confidently in comparisons.
The Gravity lacks a frunk with the same dimensions as the Air though still a decent size. However, the three cars I have mentioned have frunks that are non-existent or practically non-existent. Space wise all the trunks were nowhere close.
Three row seating did not exist for any of the cars. Length difference is only about 13"and 17" using the Air length + 2". My seating length (excluding feet) at 5'9" is more than either length, so there's considerably more to the story than just adding extra length and keeping a much larger trunk.
General interior space feels cramped relative to the Lucid for the three brands I've sat in. Upholstery is bulky. Back leg room is cramped (again relative to the Lucid).
Range is self-explanatory and been beaten into a pulp already in the thread. 440 miles of range is class leading, and with reasonable driving (from my perspective), I have achieved 500 miles in the GT on 19" and expect the same achievements in the Gravity when absolutely needed.
Charging times have not been published for the Gravity, but I expect similar times to the GT-P, Dream, Sapphire, and 24' GT. The numbers for the three vehicles I test drove are not top of the mind, but I think it safe to assume nowhere close to equivalent.
The Lucid team should be proud of their accomplishments. Calling a spade a spade in an interview is fair game. If no one is doing what you are doing in the SUV space, then it is up to your competitors to step up. Peter's statement is as mild and offending as bland porridge.
To put all this back in frame of reference of Peter's comparison points, I am pasting the quote from the article:
“Yes, there are many EV SUVs out there, but none of them are very good. I’m sorry, they’re not. None of them have anything like the dynamic performance of Gravity. None of them have the range, the practicality, the interior space, or the compactness and versatility that Gravity offers.” - Peter Rawlinson, CEO and CTO of Lucid
If you want true ridiculous and outlandish quotes as an example, look no further than Nvidia:
"The more you buy, the more you save... That's called CEO math. It's not accurate, but it is correct." - Jensen Huang, CEO of Nvidia.
