Another track record and better brakes will further improve the Model S track times according to Pobst.

"Pobst calls out the Model S’s brakes, stating that they don’t inspire much confidence. He had just gotten out of the other two cars, both of which are some 600 pounds lighter, so this is bound to make the Model S feel heavy on the brakes and in the corners. But he also giggles with delight whenever he gets a chance to floor it, and on each straight the Plaid rockets back ahead of the competition.
It should be noted that the Model S isn’t even a track car. It doesn’t have the Model 3 Performance’s “track mode” (yet?) and doesn’t have many of the track-specific improvements that more “racey” cars tend to have. For example, there’s no easy way to disable the Model S’s stability control system, which slows down experienced drivers."
