- Elon Musk states his rocket-powered Tesla Roadster will go from to 60 miles per hour (mph) in 1.1 seconds.
- That acceleration is a full next a lot quicker than any present production car.
- It’s unclear how Musk will produce a street-authorized, rocket-boosted manufacturing vehicle.
Elon Musk statements the new Tesla Roadster will go from to 60 miles per hour (mph) in a intellect-bending 1.1 seconds.
This astonishing figure would shatter existing information for generation vehicles, even amongst the maximum tier of luxury athletics cars. (Our mates at Auto and Driver say the 2015 Porsche 918 Spyder now features the quickest -to-60 acceleration at 2.1 seconds, for what it’s well worth).
➡️ You really like badass cars. So do we. Let’s nerd out about them together.
So, how could Musk obtain that total added 2nd about the competitiveness? He’ll equip the second-gen Roadster with SpaceX rocket thrusters, of training course.
People to the Petersen Automotive Museum in Los Angeles 1st spotted the jaw-dropping acceleration assertion as part of a new, two-7 days show on the Tesla Roadster. The day soon after the show opened, patrons tweeted at Musk inquiring if the assert could possibly be genuine.

Musk replied the Roadster will use a “SpaceX rocket thruster option package” to obtain people speeds. Rocket thrusters are generally relegated to the globe of spacecraft, made use of as a propulsive device for acceleration and altitude control.
As you can visualize, a experience in this model of the Roadster is not going to be for the faint of coronary heart in his tweet, Musk reported it would be “extremely powerful,” and “likely not clever for people with a clinical condition—same as a hardcore roller coaster.”
Sticking with Musk’s roller coaster analogy, let us chat about the kinds of gravitational forces (also known as g-forces) that you expertise whilst on the ride. Most coasters give off concerning 4 and 5 Gs for much less than 1/10th of a second at a time, according to a 2012 tale in the BBC.
That signifies for a short second, your human body feels about 4 to five moments heavier than regular, slamming your excess weight back again from the seat. Fighter pilots are specifically properly trained to withstand better gravitational forces of up to 8 or 9 Gs for prolonged periods of time. But those types of forces could injure—or even kill—a usual particular person.
Futurism calculated this rocket-boosted Roadster would deliver 2.5 Gs of drive on the driver, so the roller coaster analogy tracks. But so do the hazards.
Rocket-powered cars and trucks are common for professionals making an attempt to split land velocity documents, occasionally achieving about 700 mph. But those cars and trucks aren’t avenue authorized brands typically throttle luxurious sports activities cars at an arbitrary pace in the fascination of basic safety. It is really identical to the change between NASCAR’s “inventory cars and trucks” and the completely customized-crafted chassis and engines of IndyCars or F1.

Current automotive polices don’t account for rocket boosters. That indicates any hypothetical Roadster 2. (it is previously been 4 yrs considering that the auto was introduced) ought to go as a result of an completely new approvals method that would not however exist.
What does it seem like to control a manufacturer-new type of automobile? Musk is offering his SpaceX rocket offer as if it were being a different trim level, relatively than a complete reimagining of what a road-legal auto can be. But he could feel he’s observed a shortcut.
In 2018, Musk first specific what he thinks this rocket thruster solution approach will look like:

Then, he reconfirmed it in 2019.

At that time, InsideEVs did the math and uncovered what Musk described would in fact fall the predicted -to-60 acceleration from 1.87 seconds to 1.56 seconds. Musk need to have calculations to back up his 1.1-second figure—and we’ll be waiting around.

This is an fascinating puzzle. Certain, rocket cars and trucks intended to crack the land speed document are not road-lawful, but which is because of to innumerable other things, in addition to the rocket thrusters. They don’t have the ideal security characteristics to start with, and engineers make the automobiles to be as light-weight as achievable, relatively than as risk-free as doable.
But what about a entirely road-authorized auto whose only alteration is to incorporate on some chilly fuel thrusters? Perhaps it really is much less clear how regulators will strategy the subject simply just mainly because no one particular has at any time tried using it just before.
Just after 4 decades, most Tesla admirers would adore to see any Roadster—rockets or not.
