They already have: Model X
It is strange that the FF 91 has all these other whiz bang features, but they don't talk about air filtration, something critical for the smoggy markets like Chinese cities.
Interesting that the head of propulsion for FF pulled out what looked like a 18650 cylindrical cell. And given their performance and range numbers, looks like they don't have any significant advances in battery chemistry beyond what we normally see. Taking 130 kWh at 6C, is 780 kW and that's what it gets. With 780 kW (1050 hp) on tap, they can only manage to match a Model S P100D? That must be quite a heavy vehicle.
