SpaceX returns to Starship program roots with new ‘test tank’ prototype
It’s now clear that SpaceX is preparing to return to the roots of its Starship program with the latest in a series of one-off ‘test tanks’ meant to qualify upgrades to the rocket’s design and production.
Likely known as Starship SN7.2, the hardware will be the first standalone tank built and tested by SpaceX since SN7.1 was successfully pressurized to failure in a process known as burst testing in September 2020. Following in the footsteps of SN7.1, a simple test tank fully focused on qualifying a change in the steel alloy used to build Starships, SN7.2 was somewhat more complex, swapping one of two smooth forward domes with a thrust dome and adding a ‘skirt’ section.
Built out of the same steel alloy as SN7.1, SN7.2 went through similar testing but included the use of a hydraulic ram designed to simulate the thrust of one, two, or three Raptors on the ‘thrust puck’ those engines would otherwise attach to. Starship test tank SN7.2 appears to be quite similar to SN7.1 – but with one or two crucial differences.
The first difference, as noted above, is a reduction in the thickness of the steel rings that make up the outer walls and structure of SN7.2’s barrel-like tank section. SpaceX is believed to have reduced that skin thickness by 25% (4mm to 3mm) in an apparent effort to begin a weight reduction process necessary for Starships to eventually achieve their optimal payload goal of ~150 metric tons (~330,000 lb) to low Earth orbit.
From some angles, SN7.2’s steel rings do appear slightly flimsier or more liable to warp from the heat of welding than other test tanks in the SN7 range, but the differences are rather subtle. Regardless, a reduction from 4mm to 3mm steel rings could likely cut 5-10% from an orbit-capable Starship’s empty weight. When every gram of Starship mass reduction translates directly into an extra gram of payload, it’s safe to say that SpaceX is just getting started.
It’s unclear if a successful SN7.2 test campaign will result in similar reductions to the steel that makes up Starship tank domes and noses. SN7.2’s forward and thrust domes appear to be more or less identical to almost all prior Starship prototype hardware.
Aside from thinner steel skin, it’s also possible that SpaceX will attempt to hit two birds with one stone and test a second unproven change on SN7.2 – namely an upgraded ‘thrust puck’ design. That new puck design first appeared on a November 2020 shipment from SpaceX’s Hawthorne, CA headquarters. Referring to the cone-like structure Starship’s three central Raptor engines attach to and are fed propellant through, the new design simplifies plumbing complexity by allowing Starship’s fuel and fuel header tanks to attach directly to and feed methane through the puck.
It’s unclear which thrust puck design SN7.2 has settled on, though SpaceX’s decision to make SN7.2 an engine section test tank arguably points towards the new puck. Regardless, SpaceX will almost certainly install a skirt section – two reinforced rings – underneath SN7.2 once the tank is welded together, giving it the hold-down clamps needed to secure it to a launch mount while simulating Raptor thrust.

Tesla rolls out most aggressive Model Y lease deal in the US yet
With the promotion in place, customers would be able to take home a Model Y at a very low cost.
Tesla has rolled out what could very well be its most aggressive promotion for Model Y leases in the United States yet. With the promotion in place, customers would be able to take home a Model Y at a very low cost.
Zero downpayment leases
The new Model Y lease promotion was initially reported on X, with industry watcher Sawyer Merritt stating that while the vehicles’ monthly payments are still similar to before, the cars can now be ordered with a $0 downpayment.
Tesla community members noted that this promotion would cut the full payment cost of Model Y leases by several thousand dollars, though prices were still a bit better when the $7,500 federal tax credit was still in effect. Despite this, a $0 downpayment would likely be appreciated by customers, as it lowers the entry point to the Tesla ecosystem by a notable margin.
Premium freebies included
Apart from a $0 downpayment, customers of Model Y leases are also provided one free upgrade for their vehicles. These upgrades could be premium paint, such as Pearl White Multi-Coat, Deep Blue Metallic, Diamond Black, Quicksilver or Ultra Red, or 20″ Helix 2.0 Wheels. Customers could also opt for a White Interior or a Tow Hitch free of charge.
A look at Tesla’s Model Y order page shows that the promotion is available for all the Model Y Premium Rear-Wheel Drive and the Model Y Premium All-Wheel Drive. The Model Y Standard and the Model Y Performance are not eligible for the $0 downpayment or free premium upgrade promotion as of writing.

Tesla is looking to phase out China-made parts at US factories: report
Tesla has reportedly swapped out several China-made components already, aiming to complete the transition within the next two years.
Tesla has reportedly started directing its suppliers to eliminate China-made components from vehicles built in the United States. This would make Tesla’s US-produced vehicles even more American-made.
The update was initially reported by The Wall Street Journal.
Accelerating North American sourcing
As per the WSJ report, the shift reportedly came amidst escalating tariff uncertainties between Washington and Beijing. Citing people reportedly familiar with the matter, the publication claimed that Tesla has already swapped out several China-made components, aiming to complete the transition within the next two years. The publication also claimed that Tesla has been reducing its reliance on China-based suppliers since the pandemic disrupted supply chains.
The company has quietly increased North American sourcing over the past two years as tariff concerns have intensified. If accurate, Tesla would likely end up with vehicles that are even more locally sourced than they are today. It would remain to be seen, however, if a change in suppliers for its US-made vehicles would result in price adjustments for cars like the Model 3 and Model Y.
Industry-wide reassessments
Tesla is not alone in reevaluating its dependence on China. Auto executives across the automotive industry have been in rapid-response mode amid shifting trade policies, chip supply anxiety, and concerns over rare-earth materials. Fluctuating tariffs between the United States and China during President Donald Trump’s current term have made pricing strategies quite unpredictable as well, as noted in a Reuters report.
General Motors this week issued a similar directive to thousands of suppliers, instructing them to remove China-origin components from their supply chains. The same is true for Stellantis, which also announced earlier this year that it was implementing several strategies to avoid tariffs that were placed by the Trump administration.

Tesla owners propose interesting theory about Apple CarPlay and EV tax credit
“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.
Tesla is reportedly bracing for the integration of Apple’s well-known iOS automotive platform, CarPlay, into its vehicles after the company had avoided it for years.
However, now that it’s here, owners are more than clear that they do not want it, and they have their theories about why it’s on its way. Some believe it might have to do with the EV tax credit, or rather, the loss of it.
Owners are more interested in why Tesla is doing this now, especially considering that so many have been outspoken about the fact that they would not use it in favor of the company’s user interface (UI), which is extremely well done.
After Bloomberg reported that Tesla was working on Apple CarPlay integration, the reactions immediately started pouring in. From my perspective, having used both Apple CarPlay in two previous vehicles and going to Tesla’s in-house UI in my Model Y, both platforms definitely have their advantages.
However, Tesla’s UI just works with its vehicles, as it is intuitive and well-engineered for its cars specifically. Apple CarPlay was always good, but it was buggy at times, which could be attributed to the vehicle and not the software, and not as user-friendly, but that is subjective.
Nevertheless, upon the release of Bloomberg’s report, people immediately challenged the need for it:
Everyone thinks they need it. I would think that too if I didn’t know how good Tesla’s interface was. CarPlay is a crappy layer on top of crappy info-navs, and people think it’s an imperative because it provides a level of consistency from car to car. They have no clue how much…

How can it not be when the best engineers choose Tesla over Apple and Tesla’s core focus is auto vs Apple being mobile. It’s what Tesla does every day. It’s a side project for Apple. Still Apple is much better than any other auto OEM who attract lesser talent and make digital…

Some fans proposed an interesting point: What if Tesla is using CarPlay as a counter to losing the $7,500 EV tax credit? Perhaps it is an interesting way to attract customers who have not owned a Tesla before but are more interested in having a vehicle equipped with CarPlay?
“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.
Tesla has made a handful of moves to attract people to its cars after losing the tax credit. This could be a small but potentially mighty strategy that will pull some carbuyers to Tesla, especially now that the Apple CarPlay box is checked.
