That 1.1 second 0-60MPH
That 1.1 second 0-60MPH estimate was based on the YouTube channel Engineering Explained mathematical analysis estimating the quickest possible acceleration based on the specs provided. The great advantage of the Tesla Roadster with potentially 10 cold air thrusters added is that they could potentially achieve better acceleration, braking, and handling than any other production car in the world, because all other cars are limited by the traction capabilities of their rubber tires. Tesla does have experience with cold air thrusters from Space X engineering projects, but it still remains to be seen if it can be translated to automotive use anytime soon. If they can it will be an amazing victory for Tesla EVs against gas powered cars that have been undefeated in their performance capabilities for more than a century.
