"Motor Trend" posted a report yesterday that included these interesting tidbits:
"If your head is still spinning from the claimed acceleration and top speed numbers, know that the brakes on the Air Sapphire are pretty special. Up front you'll find massive, 16.5-inch Lucid-branded and Akebono-developed carbon-ceramic rotors gripped by 10-piston calipers. The rears measure 15.4 inches in diameter and utilize four-piston calipers. Also, the brake rotors "use a woven continuous carbon fiber rather than the discontinuous [chopped] carbon fiber" featured on most carbon braked road cars. The major benefit of a continuous carbon-fiber weave is three times more heat conductivity. Which, for a 2.5-plus-ton car capable of cresting 200 mph, is critical.
"Lucid maintains that the Air Sapphire, as well as future Sapphire products, will be more than just a straight-line juggernaut. Rather, Sapphire vehicles will be fully developed performance cars. First and foremost, as the two motors that make up the Megawatt Drive aren't mechanically linked, the car has the capability to spin one motor (on the outside wheel) forward, while the other (inside wheel) begins regenerative braking. That latter part means the wheel effectively tries to spin backward, i.e., torque vectoring. Also, this next part is a little tricky, but let's say each rear motor makes on the order of 400 horsepower (to be clear, that's just a random figure, not an actual specification). When one motor goes into regen, the energy it was using is now free to flow into the forward-spinning motor, creating as much as 670 hp. Nuts, huh? Lucid claims this sort of two-motor torque vectoring is both quicker and more effective than rear-wheel steering."
Given that the Tesla Model S Plaid is notoriously under-braked for a car of its power and has sketchy handling at the limits, the Lucid Sapphire seems poised to do a lot more than just out-accelerate a Plaid.
