Elon Musk's claim that Tesla Roadster will be able to do 0-60 mph in under a second

Introduction
It is possible with thrusters," Rimac acknowledged in a response to a Facebook comment under a photo of the engine for Bugatti's new Chiron sports car. "We did the simulation."

However, the Croatian auto executive added that there may be some drawbacks to accelerating that fast.

"Problem is," he said, "you release the air in 2-3 seconds, and then you have a lot of dead weight that you are carrying around (tanks, compressor, valves, nozzles, etc.)"

Nevertheless, the Bugatti CEO said that thrusters "are really the only way to go" since alternative methods of acceleration, like suction fan technology, would be too impractical. Though a few sports cars have incorporated suction fans, Rimac dismissed the technology due to the Roadster's weight and the "massive" equipment required.

Musk didn't elaborate on how the Roadster would be equipped to break Rimac's record, saying only that the acceleration was "the least interesting part." Tesla did not return a request for comment before publication.

Previously, the Tesla Roadster was billed as reaching 60 mph in 1.9 seconds, a figure that is still up on Tesla's website.

Production design on Tesla's second-generation Roadster is complete, Musk posted, adding that the company expects to formally unveil the vehicle by the end of the year. Tesla aims to start shipping the first production models in 2025.

Conclusion
"I think it has a shot at being the most mind-blowing product demo of all time," he added.

It's not the first time the Tesla CEO has made big promises. Tesla weathered criticism last year after Cybertruck drivers pointed out that many of its specifications, including its range and price point, were not what had been initially announced.
