Zak Edson, the VP of Sales & Service, told me that the chassis was actually engineered to take four motors, but that three would be the maximum for the sedan. So . . . four for the Gravity? A pickup truck?
The current Air has an almost perfect 50/50 weight distribution, while the tri-motor Plaid has a 46/54 weight split. As the Lucid drive units weigh considerably less than Tesla's (and the Air starts out as a significantly heavier car), perhaps there won't be as much rear weight bias in the tri-motor Air as in the Plaid. I find our Air better planted under hard acceleration and more balanced in turns and quick lane changes than our Plaid and hope Lucid doesn't lose that sense of balance and precision.
