27:25 - "7g for 6 seconds could make a person black out" - After accelerating at 7g for 6 seconds, you are going 920 mph, so I don't think this will be a concern

It's ridiculous that they took the full payment and didn't deliver the product in a reasonable time frame.

I was talking with a Porsche salesman one time and I asked him who would ever buy an electric Boxter and he answered, “all those people that never got their tesla roadster, they can go buy one”

In true Tesla fashion it will underdeliver in performance, be way behind schedule, and completely overshoot it's price point

The last time Tesla prematurely unveiled something, all their competitors started designing, producing, AND shipping pickup trucks before Tesla could. Watch Dodge come out with a gas thruster Charger before the Roadster 😂

I kind of decided a few years ago that anyone defending Tesla’s ridiculous promises was no longer trustworthy about anything. I say that as a long time Tesla owner.

Next gen Tesla Roadster is turning into Half Life 3

Fun fact Tesla doesn’t have a functioning refund process for the Roadster.

Cold gas thrusters is just a fancy name for CO2 canisters lol. So imagine having to find a place to refill your car with C02.

Elon needs to pump tesla stock, he has to sell more shares to cover twitter

He made a tweet, and got 30 minutes of airtime. He got a screaming deal.

At this point, the scale of Elon Musk’s deception is huge and it would be awesome for MKBHD to do a bit of research and point it out. This is going to be at the scale of Enron.

There is pretty much 0 chance any insurance company will accept a policy on a car that is designed to lose contact with the road surface - and the impact that has on direction control and braking. But cold thrusters that turn on briefly to shorten braking distances from higher speeds (by thrusting against the direction of travel or vertically downward), increases cornering grip or provide a bit extra acceleration during passing...that will be of great interest.

I'm glad that Marques finally called the Cybertruck absurd.

The Top Thrill Dragster roller coaster at Cedar Point does 0-60 in 1.2 seconds. Lots of people, including myself, have experienced that. I can’t imagine being in a car that could even match that acceleration.

Elon has been drinking the kool aid for some time now. I own a Tesla and love it, but someone has to pull the reins soon.

Maybe Elon saw that one Tom Scott video of a tiny car doing 0 to 100 km/h in 0.956 second.

I'm over Elon's attempt to once again make the ants scurry. It seems like every time he needs a stock bump or he's not the center of attention we get the Coming Soon shtick. Booooring.

Roller coaster enthusiast here, the fastest accelerating in the world is Do-Dodonpa in Japan, it goes 0-112 mph in 1.56 seconds. Roaster is slow as shit aha. Do-Dodonpa is currently not operating though as people kept sustaining injuries from the acceleration G force (and probably not having their heads back). The fastest accelerating coaster currently operating is possibly Stealth at Thorpe Park which does 0-80mph in 1.9 seconds, so most likely thats 0-60 in under 1.5 too. Also at 26:49 this is incorrect, these G force numbers refer to vertical acceleration, not forwards. The reason you black out is the blood draining from your brain which only happens at these G forces when it's vertical. So this would only happen in a fast car if you were laid on your front.

Those thrusters would require tanks so large/pressurized that if ruptured, would explode like a crate of TNT.

Waveform "clips" Posts a clip of half an hour long

This episode begs for an @EngineeringExplained collab

Your g force calculation ignores the standard 1 foot of rollout distance given to 0-60 times. Its extremely important as you get faster. The model S plaid with a 1.99s time gets up to 6mph in the first 1 foot of travel before the clock starts. Plaid really goes 6-60mph in 1.99s

Miles Somerville 🙌 future MKBHD 🤛 natural talent dude keep it going ✌

A cool feature would be to somehow charge the compressed tanks from braking the car. Basically the inertual energy ofthe cars to stop will push air into the tanks abd charge the thrusters. It should be possible in theory. Even to push a slight amount of air inside it due to being high pressure would make that feasible. This would limit the possibility to use the thrusters very often but would not require charging anymore. And would use the kindetic energy lost when stopping the car either way. Instead of charging the batteries.

Just wanted to say that the color grading in this video, especially on Miles, is excellent! As a person of color myself, I'm critical on how often color grading doesn't take into account darker skin tones. KZfaq channel editors are especially egregious here. Good job!

I do remember that there was a new report a few years back of an officer in California taking someone's registration because the car has a track mode. Normally it's accepted that such features are legal as long as they're not used on public streets, which this guy did do, but the officer and the department argued just having the feature made the car illegal due to the noise level limitations. I could see similar happening with the Roadster if the law is followed the same way.

When they unvailed the roadster they claimed it was 200kwhr with "Today's tech". They claimed they could do everything now.

That 500 times comment had me cracking hahahaha

Elon full of promises

I wonder if there using the cold air to turn the massive thing in a track because of how heavy it would be like add small amounts of lift to lesson weight to cut corners faster

I had a deposit down on a Foundation Roadster, but a year later when it became obvious that the product would not be delivered any time soon I requested and received a full refund. And it's clear now that if they ever actually ship this car, like the Cybertruck the vehicle delivered will not meet any of the extravagant claims they made pre-release.

Cold air thrusters. The air was supposed to be pressured into a carbon wrapped pressure chamber at about 6000psi (crazy high) and if you want this package you lose the back seats. I can imagine 2 thrusters pointing down to give downforce. 2 pointing back to give back to improve acceleration. 2 up-front for braking. and 2 each side for steering.

Makes more sense to aim the thrusters up and momentarily increase downforce in turns then to point them down and make it hop. could even thrust only on the inside of the turn to increase the grip on the inside unloaded tyres. But the point is mute, the size/weight of the tanks required to last a lap/multiple laps would be impractical, street use would be moronic. On board compressors would just make this worse.

What limits vehicle acceleration is the tires grip, you can't do 2G+ acceleration without F1 tires AFAIK

i was very impressed with Teslas back then but man it's really just been one disappointment after another ever since... a delayed semi, very delayed and more expensive Cybertruck, full self-driving still not anywhere close to being a thing and then whatever happened to the roadster. and that all while the competition didnt sleep if not surpassed tesla...

I thought "Sousian" comes from the renowned composer and music conductor John Philop Sousa. You know, the guy that wrote The Stars and Stripes Forever and many other marches. He was most well known for his marches which primarily accentuate the brass instruments like the trumpets and trombones.

Tesla isn't Rivian lol. Rivian reveals and produces quality cars. Tesla reveals and produces hype

Bet they will be ready by the end of the year... Like everything EM does.

Edit: It's titled "2020 spacex tesla roadster 0-60 in 1.1s!" and theres a watermark so it might be an edit. Theres a super grainy short that i come by every once in a while of a roadster with a spacex emblem on the back accelerating and its completely nuts

Have you guys heard about Rimac?? Did you know it is a 2 door car that came out of no where??

It would be nice to see how tight the turns will be. There is the problem of the air jet denting nearby cars, or flesh. 😬

These conversations are very enjoyable. I'm not an engineering nerd and I'm on the wrong side of 50, but I enjoy this show immensely.

what happens if you get in a accident with all that compressed air or if the battery catches fire?

Are they maybe using the vacuum technique which is used in the world record car from ETH Zurich? This concept could fit in a street legal car and would be save also I think. Why do you think they would use something like rocket thrusters?

I don’t think the car will be able to jump. I think the thrusters are there to keep the car on the road instead, and perhaps help with the acceleration. I just don’t see much point to it otherwise, you’ll lose control of the vehicle and I doubt it’s capable of actually flying with cold gas.

Do you realize that Elon just got you to talk about this rocket vaporware for a half hour to millions of people? This is part of his mastery of performance and persuasion. Not saying it is bad, but just so you know that you totally just gave him free promotion to millions of viewers. (See MadMen's VW Bug scene).

Technically, the Cold gas thrusters are still moving the car with electricity, since the compressor is powered by the battery power.

Engineering Explained did a great video on the feasibility of the thrusters a year or two ago. The tanks and compressor required would take up a significant amount of space (the entirety of the rear passenger volume) for what would amount to a gimmick. The thrusters would be exceptionally loud and illegal to use pretty much anywhere outside of select dragstrips. They would also be outright dangerous under braking or while turning, as those are times when consistent acceleration/deceleration is vital to maintaining good vehicle control. Imagine going through a long sweeper at high speed and then instantly washing out and crashing because you no longer have the lateral acceleration from the thrusters helping your tires...

Stop giving Elon Musk credit. I'm so tired of his lies.

9:30 Maybe the best thing for a car like the Roadster would be a supercapacitor bank. Huge power, minimal concern for range, less weight.

They could probably do software like personal drones have that are blocked from operating in certain areas, certain times, and/or certain conditions.

I'm not sure who Miles is but he's awesome! Great addition.

I think this podcast has put more thought into the roadster than Elon or Anyone at Tesla

The only thing I'd find interesting in the Roadster would be if they advertise it at

Guys, I think a half hour video can’t be called clips..😂

Roadster with rockets will be like the Cybertruck boat, a fantasy.

I'm fairly sure he was just planning on light weight re-bodying a model s plaid power train, now he's worked out that won't work.

Can’t wait to see it in the wild

8:45 If you are going to put thruster on the car, you make them push the car *forward*, so you don't even have to worry about traction limits....

If you don't apply power through the tires, you don't really need to worry much about grip.

21:00 - the most powerful roller coaster launch in the world, Do-Dodonpa in Japan, is 0-112 mph in 1.56 seconds. No way the roadster is even going to sniff that acceleration. Still going to be super cool, though.

Carlton and Will making a reunion episode

Perhaps the roadster will have ground effects like the Gordon Murray T50 fan car?

One of the biggest reason why the roaster has been delayed is the chief engineer who designed the new roaster left to work for Ford. It was a huge setback.

7:27 when it comes to 0-60 it’s about traction, not really horse power, you could give a car 6000hp, it’s not gonna be under a second

Not me listening to this on my my way to get ingredients for shepherds pie.

There's a big difference between using a cold gas thruster (i.e. a canister of compressed gas) to change the orientation of a rocket in free fall or give a light push to a maneuvering unit weightless in space, and then using the same technology to lift an entire car with a heavy battery in it off the ground in full Earth gravity - as in: the latter isn't going to happen. (Also it's an absurdly stupid idea to do it, even if you could)

Speaking of items on the Tesla drawing board, what happened to Tesla Pi (super Smart Phone) ???

Maybe the SpaceX is just like a trim level, with just some space theme visual details.

the noise wont be a probleme because it will only last for 1-2 seconds 😀 also a lot of sport cars have non legal exhaust noise when esxhaust valves are open. the worse will be the noise of the compressor inside the cabin...

The issue with a sub 1 Second 0-60 time at a Drag Strip is that Drag Strips have rules. A car with that engineering ability would need a *BUNCH* of safety equipment for a Drag Strip, so... even then, it can't be used?

Color matching on fleek

Why ship products when you can get risk free returns on your customers pre-order money?

It's Elmo. Of course he'll just be talking out of his ass. If he opens his mouth, assume he's lying.

6:46 Those thrusters are NOT CGTs. They burned hydrazine with nitrogen tetroxide. Most RCSs that actually reach space are not cold gas based (performance is kind of crap).

The roadsters main issue was the plaid coming out. O-60 in 2 seconds in the sedan set the bar so high they have to absolutely crush it to make the roadster really appeal

what about topfuel dragsters as a reference? or are they even faster accelerating?

Range will surely be max 400miles, realistically around 300miles. All the other specs seem to be in the realm of possibility for Tesla to execute.

Transport of compressed gas requires specific licensing. The SpaceX package would require specific licensing to drive on public roads, at the very least.

Since they announced the Roadster, Lucid designed, produced, and shipped the Air Sapphire which already achieved a 9.8 quarter mile and 1.86 0-60

can't wait to see MK fit in the Roadster..

"sub 1 second 0 to 60".... do you guys know about the Plaid "1.99 second 0 to 60" where it says "rollout subtracted"

@mkbhd you should invite @scottmanley to answer all your rocketry questions.

The BYD Yangwang U9 can jump so if the Roadster doesn't hoover I don't care. I can see them using thrusters in a up-backwards direction like dragsters use their zoomie pipe to push the car into the ground. Still think the McMurtry Spéirling will be pretty hard to beat.

Maybe there are no motors on the wheels and instead there's front-facing fans powered by those same crazy motors. Sounds Aeronautical and would explain him saying '(...) if you can call it that.'

pushing the car down doesn't require less horsepower to accelerate the car, actually slightly more. it just increase downforce, thus how much horsepower you can transfer from the tires to the ground. its like thinking putting a huge wing on your car is going to make it faster in a straight line also thrusters will generate a certain thrust that at a given speed could be expressed in horsepower, but thats not how you measure the performance of thrusters. the roadster without thrusters is advertised 1.9s 0-60mph, that is around 1.5G to fo under 1s, 2.8G, the spacex version will need at least 1.3G of thrust to go under 1s. I'm not even counting the weight of the system. if the roaster is about 5000lbs, that's about 65000lb of thrust, thus why the car would be able to fly if thrusters under the car have similar thrust if the exhaust velocity is around 600m/s which ive read somewhere, it would mean abut 100lbs of air being expelled every second. at 10000 psi that is ~50kg/s or 100lbs/s then you have to consider that when tank starts to lose pressure, gas wil exhaust slower, creating less thrust/ lb of air, so youd need probably double the amount of air in the tank (last half is not used. even at 10000psi that means 30 gallons air tank for 1 sec of thrust. the tank would hold 200lbs of air when full and be half empty after 1s (one 0-60) The biggest bottleneck will be the time (and energy) required to pressurize back the compressed air tank. also if the quicker the compressor, the bigger/heavier/noisier it will be. are you ready to lose dozens of miles of range just for one second of acceleration, and then hear a loud air compressor for 15 minutes? it's like filling a scuba tank, with a compressor, except higher pressure, and bigger. its a huge amount of noise & heat generated

Cant imagine it being road legal. Imagine having tanks in back with thousands of psi in it. Crashing or wrecking and going off like a bomb.

I’ve broken a decibel meter before with a sound system lol

To all those who preordered the roadster: I got some nice beans for you, the grow a stock into the sky over night! Or how about my new „magic musk marvellous medicine“ elixir, made from only the finest rattlesnakes!

It’s obviously easier to land a car than a rocket and the spaceX tech for landing rockets is incredible. When I saw Elon’s tweet that said this is gonna be the coolest tech demo ever, I just imagined them yeeting the car off a roof and it just uses the cold thrusters to re-orient and land itself on the stage. Now that would be cool.

Superman: Escape from Krypton may be the closest. It’s 0-100 in 7sec

Same cold thrusters that don’t work on Starship!😂

IT WONT have the 500 Mile RANGE wasn't the CYBERTRUCK MENT to have a 500 MILE RANGE ?

finding clients for the 1s 0-60 spaceX package wont be the problem they will be low volume and very hard to get. any supercar is always much more sought after in the most radical, low production track version. they hold and even gain value WAY more than the base versions. they barely have 10hp more, some carbon fiber, louder exhaust and charge 50k or more for that the spaceX roadster would be a hugely collectible item even if the cold thrusters never get used because they're not practical. there's always people queuing instantly for any 500k+ super/hypercar

Didnt elon said that the acceleration and speed is the 'least' interesting part of the new roadster? I vaguely remember that and I hope it has holograms or HUDs lol

That was a nice, relateable talk! My point of view is, that Tesla under Elon Musk was planning to do the Roadster 2.0, but as they learned more about R&D costs for their core mission cars alone, they found out, that they can not afford it so far. But they used the tech they had demoed and planned to put into the new Roadster into the Tesla plaid instead, as a preview and even more usable and volume selling replacement. As you pointed out - its as useless as most Hypercars in real life and there seems no reasonable way to actually use cold gas thrusters other than the short time downforce enhancing idea. To be honest: I hope the next Tesla Roadster 2.0 Tech demo will be showing an actually electric flying car with cool specs and design.

I'm not expecting anything out of this world with the Roadster. But if the base version can outperform a Bugatti Veyron, it will live up to its name

You can calculate the teoretical limit of a car's acelleration, based on weingt, tyres, power etc. For the Tesla, it's higher than what Elon claimed. Yes, with thrusters, you can do better, but they were not a talking point at the reveal.

Even if it does, it will be old news.
