The Tesla Cybertruck attracts an equal amount of supporters and critics, with the latter group seemingly determined to prove that the stainless steel all-electric pickup truck is weak, useless, and dangerous. Critics, for one, have argued that the Cybertruck’s steel body could get dangerously hot under the Sun — but as per a recent test by a Tesla owner, this is not necessarily the case.
In a post on the Cybertruck Owners Club, a Tesla owner who goes by the username Stuck4ger shared a particularly interesting story. As per the Model Y owner, he happened to encounter a Cybertruck that was out in the Sun at the Merritt Island, FL Service Center. He touched the Cybertruck’s hood and he found it hot, but when he put his hands on the hood of a Model S parked next to the steel pickup, the all-electric sedan seemed hotter to the touch.
Fortunately, the Model Y owner had an IR temperature sensor, which he decided to use on the Cybertruck, as well as several Teslas that were nearby. The other Teslas that were tested by the EV owner were painted black, midnight silver metallic, and white. The results of the short, informal test were quite surprising, to say the least.
There’s been some discussions about how “dangerously” hot Cybertruck’s stainless steel will get in the Sun.
A Cybertruck owner club member put this myth to bed. Here are the results from cars parked in the same angle as the sun:
Cybertruck Stainless: 106°F
Solid Black: 144°F… pic.twitter.com/tplL1efIVx— Nic Cruz Patane (@niccruzpatane) March 29, 2024
As per the Tesla owner’s findings, the Cybertruck with its steel panels registered a temperature of 106.1 F (41.17 C). In comparison, the white-painted Tesla registered a temperature of 107.3 F (41.83 C), and the midnight silver metallic Tesla registered a temperature of 140.0 F (60 C). Unsurprisingly enough, the hottest vehicle in the simple test was the black-painted Tesla, which registered a temperature of 144.6 F (62.56 C).
The quick IR temperature sensor test showed that the Cybertruck could have a similar temperature as a white-painted Tesla under the Sun. That bodes well for the all-electric pickup truck, especially since the vehicle would likely find itself exposed to the Sun more often than its stablemates. The Cybertruck, after all, will likely be parked in the driveway more often due to its size, or it may be exposed to the elements during camping trips.
All vehicles tend to get very hot if they are left under the Sun, and the Cybertruck is no exception. Fortunately for the vehicle, it would appear that Tesla’s material of choice for the all-electric pickup truck is pretty safe, at least with regards to how it handles heat.

Elon Musk: Self-sustaining city on Mars is plausible in 25-30 years
Musk noted that true self-sufficiency requires Mars to develop “all the ingredients of civilization.”

Elon Musk has stated that a self-sustaining human settlement on Mars could be established in 25-30 years, provided launch capacity increases dramatically in the coming decades.
Speaking at the All-In Summit, the SpaceX CEO said building a self-sufficient colony depends on exponential growth in “tonnage to Mars” with each launch window, highlighting Starship’s role as the company’s pathway to interplanetary initiatives.
Mars settlement goals
Musk noted that true self-sufficiency requires Mars to develop “all the ingredients of civilization,” from food production to microchip manufacturing. Starship Version 3 is expected to support the first uncrewed Mars test flights, while future iterations could reach 466 feet in height and deliver larger payloads critical for settlement. Ultimately, Musk stated that an aggressive timeline for a city on Mars could be as short as 30 years, as noted in a Space.com report.
“I think it can be done in 30 years, provided there’s an exponential increase in the tonnage to Mars with each successive Mars transfer window, which is every two years. Every two years, the planets align and you can transfer to Mars.
“I think in roughly 15, but maybe as few as 10, but 10-15-ish Mars transfer windows. If you’re seeing exponential increases in the tonnage to Mars with each Mars transfer window, then it should be possible to make Mars self-sustaining in about call it roughly 25 years,” Musk said.
Starship’s role
Starship has flown in a fully stacked configuration ten times, most recently in August when it completed its first payload deployment in orbit. The next flight will close out the Version 2 program before transitioning to Starship Version 3, featuring Raptor 3 engines and a redesigned structure capable of lifting over 100 tons to orbit.
While SpaceX has demonstrated Super Heavy booster reuse, Ship reusability remains in development. Musk noted that the heat shield is still the biggest technical hurdle, as no orbital vehicle has yet achieved rapid, full reuse.
“For full reusability of the Ship, there’s still a lot of work that remains on the heat shield. No one’s ever made a fully reusable orbital heat shield. The shuttle heat shield had to go through nine months of repair after every flight,” he said.

Tesla Model Y may gain an extra 90 miles of range with Panasonic’s next-gen battery
The Japanese company is pursuing an anode-free design.

Panasonic is developing a new high-capacity EV battery that could potentially extend the range of a Tesla Model Y by 90 miles.
The Japanese company, one of Tesla’s key battery suppliers, is pursuing an anode-free design that it says could deliver a “world-leading” level of capacity by the end of 2027.
Panasonic’s anode-free design
The technology Panasonic is pursuing would eliminate the anode during the manufacturing process, as noted in a Reuters report. By freeing up space for more active cathode materials such as nickel, cobalt, and aluminum, the Japanese company expects a 25% increase in capacity without expanding battery size.
That could allow Tesla’s Model Y to gain an estimated 145 kilometers (90 miles) of additional range if equipped with a battery that matches its current pack’s size. At the same time, Panasonic could use smaller, lighter batteries to achieve the Model Y’s current range.
Panasonic also aims to reduce reliance on nickel, which remains one of the more costly raw materials. A senior executive previewed the initiative to reporters ahead of a scheduled presentation by Panasonic Energy’s technology chief, Shoichiro Watanabe.
Tesla implications
The breakthrough, if achieved, could strengthen Panasonic’s position as Tesla’s longest-standing battery partner at a time when the automaker is preparing to enter an era of extreme scale driven by high-volume products like the Cybercab and Optimus.
Elon Musk has stated that products like Optimus would be manufactured at very high scale, so it would likely be an all-hands-on-deck situation for the company’s suppliers.
Panasonic did not share details on production costs or how quickly the new batteries might scale for commercial applications. That being said, the Japanese supplier has long been a partner of Tesla, so it makes sense for the company to also push for the next generation of battery innovation while the EV maker pursues even more lofty ambitions.

Tesla called ‘biggest meme stock we’ve ever seen’ by Yale associate dean

Tesla (NASDAQ: TSLA) is being called “the biggest meme stock we’ve ever seen” by Yale School of Management Senior Associate Dean Jeff Sonnenfeld, who made the comments in a recent interview with CNBC.
Sonnenfeld’s comments echo those of many of the company’s skeptics, who argue that its price-to-earnings ratio is far too high when compared to other companies also in the tech industry. Tesla is often compared to companies like Apple, Nvidia, and Microsoft when these types of discussions come up.
Fundamentally, yes, Tesla does trade at a P/E level that is significantly above that of any comparable company.
However, it is worth mentioning that Tesla is not traded like a typical company, either.
Here’s what Sonnenfeld said regarding Tesla:
“This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same. I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.”
Many analysts have admitted in the past that they believe Tesla is an untraditional stock in the sense that many analysts trade it based on narrative and not fundamentals. Ryan Brinkman of J.P. Morgan once said:
“Tesla shares continue to strike us as having become completely divorced from the fundamentals.”
Dan Nathan, another notorious skeptic of Tesla shares, recently turned bullish on the stock because of “technicals and sentiment.” He said just last week:
“I think from a trading perspective, it looks very interesting.”
Nathan said Tesla shares show signs of strength moving forward, including holding its 200-day moving average and holding against current resistance levels.
Sonnenfeld’s synopsis of Tesla shares points out that there might be “a little too much emphasis on the magic wand of Musk.”
Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever
This could refer to different things: perhaps his recent $1 billion stock buy, which sent the stock skyrocketing, or the fact that many Tesla investors are fans and owners who do not buy and sell on numbers, but rather on news that Musk might report himself.
Tesla is trading around $423.76 at the time of publication, as of 3:25 p.m. on the East Coast.
