But they can only benchmark the current Model 3, not the Model 3 that will be available when the Taycan comes out. And we shouldn't think the Model 3 Performance design is static. That fact that TireRack sells Tesla-spec 275/30R20 PS4S tires is a huge flag. Michelin and Tesla didn't make those for aftermarket sales. They're coming to the Model 3 P. It seems like adding the adaptive suspension is a no-brainer as well. After all, it was in the rotating CAD view of the Model 3 during the 2016 reveal presentation. Come to think of it, the reveal cars also had 275 rear tires. To make more of a splash, they could update Track mode at the same time to include more features and capabilities.
I suspect Tesla is waiting for competition, like the lower-end Taycan or G20 M3, to get closer to market before they drop these additional features on the Model 3.
Just FYI, @CarlK made the benchmarking comment...
