In April of 2019, Musk promised a 2020 Tesla Roadster that would include a 200kWh battery pack, 620-miles (998 km) of range, and a top speed of 249 mph (402 km/h). The car prototype was at the time able to accelerate from 0-62 mph (0-100 km/h) in 1.9 seconds, making it the quickest production car (prototype) ever, outsprinting vehicles like the Bugatti Veyron or Koenigsegg Agera RS.
Then in October of 2019, Tesla Chief Designer Franz von Holzhausen made an announcement stating that the new Tesla Roadster would be better than the current prototype "in every way." Now news has surfaced that Elon Musk is claiming the vehicle will be able to go 0-60 mph (0-96 km/h) in 1.1 seconds with “the SpaceX rocket thruster option package.”
Yes, with the SpaceX rocket thruster option package. It will be safe, but very intense. Probably not wise for those with a medical condition – same as a hardcore roller coaster.— Elon Musk (@elonmusk) May 20, 2021
The Roadster prototype is currently on display at the Petersen Museum in Los Angeles. The plaque on the front of it makes its mind-boggling specs clear. It notes that, with the SpaceX package: "Demonstrating the versatility of electric power and adding extra distinction to the car’s already high performance, an announced SpaceX package would outfit the Roadster with cold air rocket thrusters positioned at the rear, allowing for a 0-to-60-mph (96 km/h) acceleration time of 1.1 seconds – largely unprecedented among modern road cars.'"
Still, that's not the most impressive statement Musk has made about the Roadster. He has also claimed that he wants the car to hover. Yes! hover as in mid-air! In an interview with Joe Rogan in February of 2021, Musk said:
“I want it to hover, and I was trying to figure out how to make this thing hover without, you know, killing people. Maybe it can hover like a meter above the ground or something like that. If you plummet it’ll blow out the suspension but you’re not gonna die. Maybe, I don’t know, six feet. If we put a height limit on it, it will probably be fine.”
In the meantime, the Roadster is perhaps most famous for having been sent into space by SpaceX with a human mannequin passenger onboard while blasting David Bowie tunes from the car's sound system. While the Roadster has been to space, we still have no definite news on when exactly it will be available for purchase on land. New targets state 2022 but that could be delayed as has been the case thus far.
