I'm not familiar with all of his SPACs, but they mostly seem pretty scammy.

By now I mean the last couple of years. Prior to that he made a ton of money as an angel investor/VC who invested early in successful startups.

Source of these numbers?
If it's the manufacturers, it's always misleading.

130k+ cars don't matter when we are talking about top 10 most valuable company though.

It's pretty clear EVs aren't great for people who need to use their cars for road trips. I imagine PHEV will become a more popular drive train until batteries get cheaper and more efficient.

Adding up all the range drops is going to be tough for a lot of drivers.
10-20% less than EPA claims
10% drop after a year or two in normal initial degradation
10-20% drop in cold weather
factor in charging to 100% should be occasional

Range anxiety is still a real issue.

So, I think I've busted Edmunds and their EV 'real world range' tester/author, Jonathan Elfalan. Here is the article from Tuesday claiming that Tesla's ranges are way over-rated by the EPA:

Edmunds Tested: Electric Car Range and Consumption | Edmunds

Well that looked pretty grim, but it got me remembering - didn't Edmunds do a comparison of 'real world range' between the Model Y and the Taycan back in November 2020? Why yes, yes they did, and it was done by the same author, Jonathan Elfalan. Here it is:

Tesla Model Y vs. Porsche Taycan: Testing EPA Range in the Real World | Edmunds

Hm, that's interesting - why is this article I remember from November 2020 now dated February 3rd, 2021? To the Wayback Machine!
Here is the archived version of the original article as posted on November 19, 2020:

Tesla Model Y vs. Porsche Taycan: Testing EPA Range in the Real World | Edmunds

What's this? It's different! The testing methodology and result for his Model Y range has been altered! Apparently Jonathan didn't know the original article would be archived..

In the original article from November (near the bottom):

Max Battery Usage
A key difference between Tesla and other companies is that it makes more of its battery available for use. Electric vehicle batteries that are constantly charged to their maximum capacity tend to degrade quicker over time, so manufacturers including Porsche place stricter limits on charging and use. Tesla leaves it up to the owner's discretion and simply recommends that the max battery charge only be used for longer trips. Otherwise, it says owners should use a charge of around 90% for daily use.

The 90% charge is what Edmunds followed for its Model Y test as, again, it represents how the majority of Tesla drivers will use their car. Extrapolated out, Edmunds estimates that charging the Y's battery to its maximum capacity would have added 25 miles to its as-tested range.


That section of the article has now been changed to:

Max Battery Usage
A key difference between most luxury and mainstream electric vehicles is that luxury brands typically make more of a car's battery available for use. Electric vehicle batteries that are constantly charged to their maximum capacity tend to degrade quicker over time, so some manufacturers place stricter limits on charging and use. Both Porsche and Tesla leave it up to the owner's discretion and simply recommend that the max battery charge only be used for longer trips. Otherwise, it says owners should use a charge of around 80% to 90% for daily use.

In the interest of aligning our range testing with the EPA's estimates, which take 100% of the nominal battery capacity into account, Edmunds charges all electric vehicles to their maximum allowable capacity. You can view the real-world range for every electric vehicle Edmunds has tested here. For vehicles that have a suggested lower daily charge such as the Taycan and Model Y, there is an asterisk next to the range figure. For others without an asterisk such as the Ford Mustang Mach-E, the max range can be used on a daily basis.


So in the original article he says he charged the Taycan to 100%, but the Model Y to only 90%, because that's what they suggest in the manual for normal use. Apparently on February 3rd he realized that this was an obviously unfair way to compare the vehicles and he didn't want to risk losing credibility before releasing his new article, so he went back in time and actually charged the Model Y to 100% for the test he did last November! Comparing the altered article to the original we see he has also made up new results for the Model Y range:

Original version:

TLDR: The Taycan beat the Model Y by a whopping 70 miles in our testing, yet the EPA says it should lose by 88 miles. So what gives?
Altered version:

TLDR: The Taycan beat the Model Y by 55 miles in our testing, yet the EPA says it should lose by 88 miles. So what gives?

Looks like he gave the Model Y an extra 15 miles of range. How generous of him! But, oh no, he screwed up. Looking further through the article we see:

Original version:

The 2020 Porsche Taycan 4S, an all-new electric luxury sport sedan, was way off from the EPA estimated 203 miles of range in Edmunds' real-world driving test. Edmunds observed 323 miles and saw a better energy consumption of 32.3 kilowatt-hours of electricity used every 100 miles of driving, versus the EPA's 49 kWh/100 miles.

In contrast, the 2020 Tesla Model Y Performance with 21-inch wheels — the brand's newest small SUV — did exceptionally well in the EPA's test, earning a range estimate of 291 miles and a power consumption rating of 28 kWh/100 miles using the maximum range mode. While Edmunds saw comparable efficiency in its real-world test, at 28.4 kWh/100 miles, the overall range result of 253 miles was slightly lower than the EPA estimate.

Altered version:

Edmunds observed 323 miles and saw a better energy consumption of 32.3 kilowatt-hours of electricity used every 100 miles of driving, versus the EPA's 49 kWh/100 miles.

While Edmunds saw comparable efficiency in its real-world test, at 28.4 kWh/100 miles, the overall range result of 263 miles was lower than the EPA estimate.


So in one place in the article he gave the Model Y an extra 15 miles of range, but here he's only giving them an extra 10 miles. Woops! Interestingly, in the original article he even states that if he had charged the Model Y to 100% it probably would have given the Model Y an extra 25 miles of range (makes sense since that's about 10%). In the altered version he only gives them 10 or 15 miles depending on where you look, so he is clearly biased against Tesla and wants to give them as little range as possible in his new made up numbers.

So unless I'm missing something, he's altered his methodology for a past range test and made up new numbers go with it. This is the same guy running these new tests, where he could be accelerating and braking in different ways for the different test vehicles, or just be making up numbers entirely.

Also comparing the Taycan to Y and not S was pretty weird in the first place.

This is just sad, man. Scientology level cult loser posting. "Someone said something bad about my CultDaddy's company! Let's drag them through the dirt!"

I guess cultdaddy Elon taught the likes of you well, leading the pack of baseless smears by calling an innocent man a pedophile because he didn't like legitimate criticism.

Edmunds are a well respected car reviewer. There's no reason to call them shady just because they call out Tesla's bullshit.

The 'victim' tactic is very popular right now, especially on the right. We just laughably saw Josh Hawley go on a massive media tour to out that he was being 'cancelled' by media and none of the media outlets allowing him to air his complaint even questioned the irony in it.

So no surprise it also used here.

Existing High Speed Rail is already a superior form of transport for short distances (600 miles or less). By "superior" I mean safer, more convenient, and comparable in duration. Hyperloop would be as safe/convenient as HSR, and much faster. For longer distances, air travel would remain superior (faster).

Because hyperloop targets sub 600 mile distances, a global network of interconnected nodes is unnecessary and irrelevant. Others have proposed tubular systems for longer distances at much higher speeds with (sub-sea) intercontinental connections, but that seems much more difficult, even if it's physically possible (vacuums, etc).

A new technology could supplant all of the above (eg. rapidly re-usable rockets, teleportation, or something else), but that's out of left field.

I disagree IRT the safety aspect. If CA for example has their way in establishing passenger safety guidelines Hyperloop will never get off the ground. Way too many safety issues (vacuum environment, tunnels, G forces, egress requirements, seismic issues, flooding, etc.).

On the other hand, if CA has an ulterior motive in promoting use of Hyperloop then maybe these safety guidelines get overlooked. Not good for passengers and not good for society in general.

I fully support Hyperloop for freight, provided it is economically beneficial. (which I am confident it will be soon)

why would adding a tunnel to the hyperloop make it more economically viable?

Tunnels can go in a straight line, theoretically. At grade or above grade paths would need to navigate elevation changes and lateral obstacles.

Hyperloop operates at high speed safely only if it moves in a straight line.

heltok's is the same line of thought among twitter bulls too. "edmunds = FUD!! check out this youtube video/forum post from a heavily invested tesla fanboy proving otherwise!"

ultimately it boils down to stonk price bro. trust forum people and youtubers more than news because stock price keeps going up, which works (until it doesn't)

it's the science-nerd version of Qanon people saying "don't trust the media, do your own research!" where research is watch random wackos on youtube rant about insane ****

yeah. but what happens when one of your seals or whatever goes from 99,999999999999% to 99,999999999998% and you can't keep up your vacuum and need to replace it?

Agree freight is an excellent use case.

Minor correction: Hyperloop uses a partial vacuum.

Safety is a big topic and we can agree if it’s not solved then it should not go ahead. Taking Japan’s High Speed Rail as an analogue, there has never been a fatal accident in its 50 years of operations (10 billion passenger trips). The cutting edge Maglev HSR train is pushing 375 mph in testing (hyper is targeting 760).

Politics and NIMBYISM are relatively bigger obstacles than technical difficulty and safety issues, imho.
