Tesla Roadster II back on?

Inform yourself before getting all giddy.

Like I always said Musk invents nothing he just rehashes what has been done sometimes many decades ago.

Sure it is fast but less than 1 second to 60 is nothing more than pure fantasy for anything driven on the road. Unless it is being launched by a steam or electromagnetic catapult or rocket engine there is no way the tires and chassis can withstand that kind of torque and rpm.
F=ma, and Elon has very clearly stated he plans to use cold rocket engine technology to generate 2.5G acceleration. Speculation may include the use of compressed air rockets. As they only need to work for a partial second. Additional speculation involves the use of fluidic amplifiers (devices that manage thrust and direction) and ejector augmenters that entrain additional air for thrust benefits. Think Dyson bladeless fan.

Check the video out at the specific time, 9:17, where a fluidic propulsion system is employed to boost thrust about 2.5x, while drastically reducing discharge velocity. Not only is it possible, it is relatively easy.

Elon is on top of this technology and a partial second of 1000 pounds thrust could achieve the results through greater tire traction via downforce generated by drawing ejector air from under the car, and via direct thrust.

Remember, the Plaid's motors don't make full power until about 60MPH, due to traction limitations.

He may fall short of the claims, but still be faster than just about everybody else. Bottom line, entirely possible.

I read the whole thing. What is technically possible and how it works in the real world are two different animals. Believe whatever you want but musk has come up short on many things.
 
Legitimately fast cars seem to be dismissed when it's electric. I don't quite get that.

People dismiss Mate Rimac?

In other news, secret test footage of the Roadster II (AKA not a Roadster) has leaked:



A few kinks have to worked out before it's released. (But there is a beta program. Apply within. Please bring proof of insurance and signed release form.)

Some do. I always hear the comment that the car has no soul because it doesn’t make any noise sitting still. I get that sound can be part of the experience, though for some that seems to be an absolute deal breaker and the whole experience.

That’s more one trick than some claim about EVs. You know, the whole thing where they’re supposedly only fast in a straight line. Many of them handle extremely well, but that’s almost never considered.
 
The problem with EV's is one word simple IMO, the BATTERY! Do not let it go below 20% and don't charge it over 80% for best battery life, that is like saying don't fill the tank more than 3/4 and don't let it go below 1/4, that is close to insanity. The colder it gets the less range it has and the faster you drive or load you place on it the less range also. Who needs this sort of nonsense, I sure don't no matter how fast 0-60 they claim which does nothing anyway for many people, bad roads, archaic speed limits with rabid enforcement using speed cameras, etc make this a moot point.
Then we have the battery life expectancy as replacement cost, once the warranty is over it can be 20K+ bill.
I looked into EV and found the negatives far outweigh any positives for the vast majority of people.

If you long trip constantly the 20%-80% isn't convenient. The vast majority of how our car is used it's a non issue. Before we decided an EV would work for us my wife was interested in a Camry hybrid. If anything that would have been even worse for short tripping and not getting oil warm.

It's a use case issue. I also wouldn't buy another ICE vehicle to short trip 2 miles in either direction that never gets up to temp.

The bolded part is very subjective based on use case. Sure that probably doesn't work for you and there's plenty that agree with you. I also doubt you had serious interest in an EV to actually research it. That doesn't mean you didn't look at it objectively, but I know if I went in predisposed to not like it I doubt we would have bought one. I didn't want the Tesla. I wanted the VW ID.4. My wife chose the Tesla and now driving both I know we bought the better car for us. I guess what I'm trying to say is that I was open to an EV, but didn't go in intending to buy an EV at the time. She did and I'm glad that's what she chose.

It certainly is a use case. IMO an ICE vehicle will still outlast an EV under the situation you described. There are probably tens of millions of ICE vehicles used under those conditions, many 15-25 years old and older. I own one. The jury is still out on tens of millions of EVs going that long. If I were to guess, most of those EVs would be going in for a battery. If you don't keep a car that long it won't matter for an EV.

We know enough about the reliability of different EV's to be confident about this, in some cases.

Bolt EV: very long lasting, problems unlikely
Nissan Leaf: you're going to have problems
Early Tesla (2012 or so): likely problems at higher mileage
Anything with an LFP battery pack: no issues

Being confident "in some cases" and having documented proof unfortunately are two different stories. In the case of ICE I'd be willing to wager there are tens of millions on the road as proof.

The average miles driven per day in America is less than 40 miles. If you can charge at home, the time savings alone is amazing. Perhaps you might ask some EV owners their real world experiences. I have come to dread gassing up due to both cost and waste of time.
EVs are not for everyone; no single car is perfect for every use case. But your statement (bolded text) hardly reflects reality. And certainly not Tesla's customer satisfaction ratings, for example. Without data, it's just an opinion.

Curious; how did you look into EV?
Regarding battery life, certainly the early Leaf had horrible degredation; but not all EVs are anywhere like that. My car isn't.

We've both told this tale here multiple times but somehow we're so different than everyone else driving 40 miles a day(or whatever that number may be).

I used to believe many of the comments @Trav and others make; we are so used to ICE vehicles. I have mentioned reluctance to change many times; it's human nature. Over the past 5+ years I have come to appreciate our Model 3 and have learned that different is not necessarily bad.
Charging is the biggie. Now solar panels and the CA Supercharger map is a pretty good scenario, for sure. I could go to LA with two 20 minute stops. With a higher range car like the M3 Long Range, it might be one stop. Now I hate gas station stops and cost. It's a pain. Quite a reversal of attitude for sure. Ever go out on Sunday evening to gas up for the work week? I used to do it for 2 cars.

If these cars were so horrible, why hasn't the EV market gone belly up? Remember 5 to 6 years ago when Tesla was sure to be gone any day now? Some may chime in with "slowing", but business cycles always fluctuate. My career centered around statistical forecasting; no one can predict the future.
 
"In some cases" applies to ICE as well, right?
ICE already proved itself, see post #31. The jury is still out on the EVs. "In some cases" is for word Police, and someone like yourself playing the word game for a technicality. Not every ICE will make it to 15-25 years of age, so I used "in some cases." An accident, theft or neglect could take it out, same applies to an EV. The only problem is we don't have tens of millions of EV's the age I mentioned, so we have no "documented proof" of that kind of volume. Stay tuned.

You provided an opinion, not proof. Conjecture is not proof. I completely agree EVs are too young a product for data driven evaluation. I would make the case they will evolve in quality and longevity just as ICE has.
My point is, some ICE drive trains have proven themselves while others have not fared as well.
By the way, I have several ICE vehicles over 50 years of age. I would drive my 2001 Tundra anywhere right now. For my truck uses, ICE is a far better drive train than EV.

As you suggest, I will stay tuned. I am one of the test cases; so far so good.
