SpaceX CEO Elon Musk has shown off a rarely-seen phase of Starship construction, further confirming that the next full-scale rocket ship is rapidly coming together after operator error destroyed its predecessor on April 3rd.

Around 5 am local time (10:00 UTC) on April 5th, Musk shared a photo of a smaller secondary tank’s installation inside Starship SN4’s full-size liquid methane tank. The photo is the first time SpaceX or its CEO has offered a glimpse inside this lesser-known part of Starship production and assembly and simultaneously offers insight into a design that’s been a mystery for months. Over the last few weeks, local residents-turned-unofficial-SpaceX-photographers have captured several photos of an internal Starship header tank design far removed from the nosecone tank Musk has previously discussed.

Those header tanks are a necessity to enable Starship’s ability to quickly, reliably, and safely reignite its Raptor engines for recovery and landing-related burns. For a ship like Starship SN4, those header tanks are a sign that SpaceX may want to use the ship to perform Starship’s most crucial test short of orbit — a ~20 km (12.5 mi) flight test meant to demonstrate a skydiver-style landing maneuver. While that skydiver landing test remains several consecutive milestones distant, Musk’s April 5th photo confirms that Starship SN4 is making significant progress towards final assembly.

Known as header tanks, SpaceX’s large Starship launch vehicle upper stage and orbital spacecraft requires smaller, secondary tanks aside from the main liquid oxygen and methane propellant tanks that make up the bulk of its body. In these early stages of prototype development, those tanks serve one main purpose: reserve a small portion of pressurized propellant for Starship landing burns.

While Starship’s main tanks still need to be pressurized at all times to ensure the rocket’s structural integrity, smaller header tanks make it much easier to safely feed Raptor engines fuel during even the most chaotic of aerial maneuvers. For rocket engines, even the slightest introduction of pressurization gas or voids into the combustion process can lead to immediate destruction — a bit like how a tiny air bubble can be almost instantly fatal for humans. Starship header tanks thus ensure that only a fraction of the overall tank volume is in play during the ship’s most critical maneuvers.

Requiring both a fuel and oxidizer, Starships thus need two header tanks. Currently, Starship’s design places the liquid methane header tank directly inside the main methane tank itself. The liquid oxygen header tank, however, is situated in the very tip of Starship’s nose section, a location chosen to optimize the vehicle’s center of gravity for stability during a radical skydiver-style landing maneuver.

Musk’s April 5th photo and caption revealed that SpaceX began installing Starship SN4’s methane header tank just an hour or two after it had flipped the ship’s partially-completed liquid methane tank dome. Thanks to SpaceX’s more efficient use of a common dome design in their Falcon and Starship rockets, that dome also serves as the upper dome of the ship’s larger liquid oxygen tank. After the methane header tank is installed, a funnel-like sump will be the last addition needed to finish the section.

With the majority of Starship SN4 already in work around SpaceX’s Boca Chica, Texas rocket factory, the ship could be just a week or less away from kicking off the stacking phase of assembly. Stay tuned!

Ferrari CEO’s self-driving stance echoes Elon Musk’s — sort of

Ferrari CEO Benedetto Vigna revealed that the Italian automaker’s future will not involve self-driving, a point that echoes that of Tesla CEO Elon Musk’s — sort of.

You might be thinking, “Are you insane? Musk has been so incredibly hellbent on delivering self-driving vehicles to the public, so much so that he has even hinted that Tesla won’t need the ever-popular and widely-requested Model Y L in the U.S.

However, when it comes to electric supercars with high-performance specs and lofty price tags, Vigna’s stance is exactly what Musk wants for Tesla’s own hypercar project, the Tesla Roadster.

In a new interview with Australian media outlet Drive, Vigna made it clear that Ferrari’s ambitions for the future do not involve autonomy, simply because the company’s cars are not designed for anything but manual, spirited driving.

He said:

“We will not make fully autonomous cars — loud and clear. We want the people to have fun, not the [computer] chips. We want to have a steering wheel and a man or a woman behind the steering wheel. Otherwise, why do you buy a Ferrari?”

This seems to be a reasonable assertion. Ferraris are not made for daily commutes, cross-country road trips, or bumper-to-bumper traffic. They’re made for fast, spirited driving, and many of their buyers will only put a few thousand miles on them throughout their lifetime. True, exciting, fun driving is meant to be done manually.

That is not to say Full Self-Driving or other semi-autonomous suites are not “fun,” but they are meant to take the stress out of driving. They are made for the daily commutes, the rush hour traffic, and the parking lots and garages. It’s made to take the stress out of driving.

Tesla Full Self-Driving attempts 150-mile stress test: the good and the bad

Musk had stated in an interview in early 2026 that the Roadster would also be geared toward fun, manually-controlled driving. On the Moonshots podcast with Peter Diamandis, Musk said about the Roadster:

“This is not a…safety is not the main goal. If you buy a Ferrari, safety is not the number one goal. I say, if safety is your number one goal, do not buy the Roadster…We’ll aspire not to kill anyone in this car. It’ll be the best of the last of the human-driven cars. The best of the last.”

There are cars out there that simply are meant to be driven by humans, and Ferraris and Roadsters are a few of them. Ferrari has no true advantage in developing self-driving; their cars sell at low volumes with high price tags, and their performance specs and engineering are all geared toward spirited driving.

Tesla upgrades Model Y’s affordable trims with new interior features

Tesla has upgraded the Model Y’s two most affordable trims, the Rear-Wheel-Drive and All-Wheel-Drive, with two new interior features that bring them level with their “Premium” siblings.

The Rear-Wheel-Drive (RWD) and All-Wheel-Drive (AWD) trims, formerly known as the “Standard” offerings of Tesla’s most popular vehicle, are now fitted with the all-black headliner and a higher-quality 16-inch center screen, two features that were added to the Premium trims earlier this year.

The RWD and AWD trims of the Model Y now have a more premium interior feel with these upgrades, and it also appears to be a move by Tesla to streamline manufacturing by eliminating variance across configuration levels.

It makes production less complicated when the interior colors are all identical. Additionally, all Model Y builds now have the larger and higher-resolution screen than previous model years.

Priced at $39,990 and $41,990, respectively, the Model Y RWD and AWD are quite different from the Premium trims. Tesla aimed to make an affordable version of what has been the best-selling car in the world on several occasions, enabling more accessibility.

The differences from an interior standpoint are noticeable, as there is significantly less storage, a lack of A/C seats, and no glass roof. However, the car is still a great option and features a good powertrain, strong range ratings of 321 miles for the RWD and 294 miles for the AWD, and a great ride quality.

Tesla Model Y Standard Full Review: Is it worth the lower price?

Other shortcomings are the lack of acoustic-lined windows, which are featured in the Premium trims to help with excess cabin noise. In our testing of the Model Y Standard back in late 2025, this was perhaps the most noticeable difference between it and the Premium trim. The stereo was also a huge difference:

The RWD and AWD trims of the Model Y are still a great vehicle at an affordable price, and you can experience them for yourself at your local Tesla showroom. Test drives are always available, and it’s a great way to experience an EV for yourself, especially if you have no knowledge about them.

Tesla has its answer to auto growth, it just has to bring it to the U.S.: analyst

Published

Tesla has its answer to grow its automotive sales over the next few years, TD Cowen analyst Itay Michaeli says, but it just has to bring it to the U.S.

On Thursday, Michaeli reiterated his $490 price target and the ‘Buy’ rating he already held on Tesla stock (NASDAQ: TSLA). However, its automotive division has struggled to show sequential growth over the past few years, mostly due to its focus on AI and Full Self-Driving. Tesla already axed two of its lower-volume vehicles with the Model S and Model X earlier this year.

However, Tesla does not need to engineer an entire new vehicle to trigger an upward tick in sales; it just has to bring it from China to the U.S., Michaeli said.

He is talking about the Model Y L, a slightly larger version of the all-electric crossover that is already available in China. U.S. customers have been pleading with CEO Elon Musk to bring it to the country since its launch in Asia last year, but he’s not convinced of it because of the advent of self-driving and its importance in this particular market.

The problem is that Tesla owners have been requesting something larger that could fit a typical American family. The Model Y L is slightly larger than the standard Model Y, but some are concerned that it could still be too small to fit what most people might need.

Instead, they have asked for a full-size SUV from Tesla.

Tesla gives big hint that it will build Cyber SUV, smaller Cybertruck

Nevertheless, the Model Y L still presents a great opportunity for Tesla in the U.S., and Michaeli says that there is an additional sales opportunity of about 100,000 units, with demand potential falling somewhere between 60,000 and 135,000 units.

TD Cowen’s note to investors also analyzed that Tesla’s growth could come from a stock perspective as well, positively impacting the stock price, as it has been widely reliant on vehicle sales, even though Tesla has truly phased itself away from that being an important metric.

Tesla stands to gain greatly from the introduction of the Model Y L in the U.S., but only if Elon Musk sees it as a viable fit for the market. Families may need to see Tesla bring something larger to the U.S., or they might be forced to buy from another automaker that offers something that fits is needs for more interior space to haul around the kids.
