Model S P100D "Cheetah" over-the-air upgrade just released today. Adds 46HP, faster 0-60, faster 1/4 mile, better thermal management on repeated runs. Active suspension setup for better weight transfer on launches. Here's before and after data on the exact same car on the street. These are also with the big heavy wheels.
