This is a great video. If you remember your Newtonian physics from high school (or you at least remember that you knew it once upon a time), you should be able to follow along. It first shows that the P100D now accelerates at what is believed to be the theoretical optimum rate with street-legal tires. I love the logic of the whole process. Then, it seeks to answer the following: If the P100D drivetrain were placed into a much lighter Roadster, would it be faster due to less weight, or slower due to having less grip due to being lighter. Next, I'd like to point out this video, which once again uses Newtonian physics to determine what the fastest theoretical 0-60mph time is for any vehicle using street-legal tires. After viewing both of those videos, I'd like to draw your attention to @TrevP 's post here, where he talks about a rumored Tesla Model 3 (which is possibly a future Roadster mule in Model 3 clothing) that can reportedly accelerate from 0-60mph in 2 seconds. Fun times.
