SpaceX’s first high-flying, triple-engine Starship prototype is rapidly approaching completion at the same time as the company is preparing for the rocket’s predecessor to lift off on its inaugural test flight.

Known as serial number 5 (SN5), it will be the fifth full-scale Starship prototype completed by SpaceX since November 2019 and the fourth since late-January 2020. Following in the footsteps of Mk1, SN1, SN3, and SN4, SpaceX CEO Elon Musk has recently stated that Starship SN5 will be the first prototype to have three Raptor engines and a nosecone installed and could be the first to be outfitted with new and improved aerodynamic control surfaces.

In the meantime, Starship SN4 is perhaps less than 30 hours away from performing a third Raptor static fire test, potentially paving the way for the biggest challenge yet for a full-scale Starship prototype: powered flight. Scheduled no earlier than 9am CDT (14:00 UTC), May 13th, Starship SN4’s next static fire is meant to ensure that a replacement Raptor engine is functioning properly. If successful, the building-sized rocket will effectively be ready to attempt its first launch – also a first for the Starship program overall – pending FAA approval.

As illustrated in the unofficial diagram above, nearly all of the individual sections that will make up Starship SN5 appear to be more or less complete, excluding some ambiguity added by the interchangeable nature of some of the steel rings all Starships are built out of. For the current design and assembly strategy, Starships are comprised of eight separate sections, themselves made up of stacks of 2-4 steel rings. Altogether, excluding the conical nose section, a single Starship requires approximately 20 of those ~1.8m (6 ft) tall steel rings to reach its full height.

Currently, SpaceX has been focused on testing just the tank section of Starship prototypes, representing the vast majority of the technical challenges that must be solved to fully realize the next-generation launch vehicle’s ambitions. Excluding a smaller secondary liquid oxygen tank situated in the tip of Starship nosecones, the nose section is effectively irrelevant – putting the cart before the horse – until Starship tank sections are more of a known quantity.

When that would be the case was entirely up in the air until just the last week or so, when Starship SN4 became the first full-scale prototype to pass a cryogenic proof test, perform a wet dress rehearsal (WDR) with real propellant, complete static fire(s) with a Raptor engine installed, and – finally – pass a more challenging cryogenic pressure test in quick succession. With those milestones passed for the first time ever, SpaceX has effectively proven that it’s solved the what is arguably the most unprecedented aspect of its Starship program: building orbital-class pressure vessels for pennies on the dollar on the South Texas coast.

Of course, doing it once with Starship SN4 is not the same as fully confirming that SpaceX’s extremely exotic South Texas rocket factory is capable of producing repeatable results with future rockets. While incredibly improbable, Starship SN4’s multiple successes could be a fluke. Additionally, as Musk has noted, the goal is to complete two entire Starships every week once the factory is fully optimized. SpaceX has already achieved a monthly production rate for its current line of prototypes, an extremely encouraging sign for the practicality of Musk’s stretch goal.

In the prototype stage, that speed of production has been incredibly useful, enabling SpaceX to move at a pace of launch vehicle development almost unheard of since NASA’s Apollo Program. At the moment, Starship SN4 has passed all tests thrown at it so far and will soon be attempting the riskiest Starship test yet with its inaugural hop attempt. If the ship were to be destroyed, one would traditionally expect a bare minimum of a few months of program delay. Instead, Starship SN5 could be more or less complete even before SN4 receives FAA permission for its first flight, meaning that a replacement will already be ready to roll to the launch pad if or when SN4 is destroyed.

Aside from Starship SN5, SpaceX is also making great progress preparing Starship SN6’s various subsections. (NASASpaceflight – bocachicagal)

In a best-case scenario, if Starship SN4 continues to pass the tests thrown at it, including one or several hops, SpaceX will instead be entering a new phase indicative of what’s to come: the concurrent testing and operation of a fleet of Starships. A step further, if Starship SN4 succeeds, Starship SN5 appears to be on track to become the first prototype to have a full three Raptor engines and a nosecone installed, as well as the first to attempt a high-altitude (20 km/12 mi) flight test.

Tesla makes the cut on California’s newest EV Rebate program

California just signed a $270 million EV rebate into law and it starts this summer.

Published

California Governor Gavin Newsom signed SB 168 into law on Monday, July 13, 2026, creating a $270 million EV rebate program that delivers money directly at the dealership rather than as a tax credit applied months later. The program, called MyFirstEV, is funded equally by California’s state budget and participating automakers, with each contributing $135.5 million to make the math work.

The timing is directly tied to the loss of federal support when the $7,500 federal EV tax credit ended, removing the most significant consumer incentive that had driven EV adoption in the U.S. California, which accounts for roughly one-third of all EVs sold nationally, moved to fill that gap with a state-level replacement.

The rebate structure is straightforward. First-time EV buyers can receive $3,500 off any new battery-electric vehicle with an MSRP up to $50,000. Used EVs priced at $25,000 or below qualify for a $1,750 rebate. The credit is applied at the point of sale, which removes the friction of the old federal system where buyers had to wait for tax season to see the benefit. The program goes live later this summer, with the California Air Resources Board expected to release full participation details next month.

For Tesla buyers, the implications are mixed. The Tesla Model 3 RWD at $42,490 and the Model 3 Long Range at $47,490 both fall under the $50,000 cap and would qualify for the full $3,500 rebate for first-time buyers. The Model Y, which starts at $44,990 after Tesla’s recent price adjustment, also qualifies. The Model X, Model S, and Cybertruck all exceed the cap and receive no benefit. As Teslarati has reported, the program also includes a carve-out exempting California-based automakers like Rivian and Lucid from the price cap entirely, a provision that puts Tesla at a disadvantage since it relocated its headquarters to Texas in 2021.

Other qualifying vehicles include the Chevrolet Equinox EV, Ford Mustang Mach-E, Hyundai Ioniq 5, Kia EV6, and Volkswagen ID.4.

Tesla Semi enters new Pilot Program with interesting challenge

The Tesla Semi is entering a new Pilot Program with Paper Transport, LLC (PTI), a Wisconsin-based transportation provider. The company will test the Semi’s Long Range configuration through “dedicated operations within the Chicago market.”

Chicago presents an interesting challenge for the Semi, as it will be a colder-weather climate that will test the Semi’s ability to operate in lower temperatures and in potentially large accumulations of snow. This is something Tesla has been testing with the Semi in Alaska and even in Northern California during the colder months, but Chicago will present a truly tough midwestern winter.

PTI says it is using the Semi to evaluate its strategy of reducing transportation emissions while maintaining performance, reliability, and cost efficiency. These are major arguments for the Semi being introduced into new fleets.

CEO of PTI Tyler Ellison said:

“PTI has been a leader in sustainable transportation solutions for over 15 years. We take a consultative approach to helping customers identify and implement the right transportation solution for their network. Our partnership with Tesla expands our portfolio alongside renewable natural gas and intermodal, giving customers more ways to reduce Scope 3 emissions without compromising service or economics.”

PTI is far from the first company to adopt the Semi within a fleet, as Tesla entered strategic agreements with PepsiCo. and its subsidiary Frito-Lay for a Pilot Program that extended throughout the California region.

Tesla has let companies like those utilize the Semi to determine whether it would be suitable for their operations. Additionally, Tesla gets valuable information regarding the Semi’s performance, knowing what to improve and what is ideal for companies that will utilize the all-electric truck for regional and nationwide logistics.

PTI plans to utilize the Long Range configuration, which is priced at $290,000 and features a range of approximately 500 miles, a three-motor powertrain, up to 800 kW of drive power, and consumption of just 1.7 kWh per mile.

VP of Maintenance at PTI, Bryan Ellen, added:

“We are excited to partner with Tesla, leveraging their ever-evolving technology. We are bullish in our estimation of the parallels available between our dedicated model and the efficiency of their fully electric Class 8 tractor. We anticipate a growing synergy between our businesses as we work to facilitate this sustainable solution for our customers.”

PTI has logged more than 87 million miles using sources like compressed and renewable gas, but now is looking to take it a step further with fully electric operations.

Tesla is building a wheelchair-accessible Robotaxi

Tesla revealed on Monday that it is building a new autonomous vehicle at Gigafactory Texas, its plant just outside of the City of Austin. This particular vehicle will be geared toward those who are in need of a wheelchair-accessible car that would require no human driver for operation.

According to a new report from Wired, Tesla’s Senior Policy Advisor, India Herdman, told members of the Washington D.C. City Council on Monday:

“We are in development for a purpose-built, wheelchair-accessible autonomous vehicle. We know that paratransit can be very difficult, and people who are confined to wheelchairs permanently should still be able to move around freely, so that is an active product being built by Tesla in Texas.”

This builds upon what CEO Elon Musk said last year on X, which confirmed the company was working on accessible rides within its Robotaxi platform, which currently is confined to the Model Y.

Tesla is also developing the Cybercab, which started employee rides last week. However, this vehicle is not necessarily geared toward wheelchair accessibility.

That leaves a major gap in the autonomous ride-sharing program that Tesla is attempting to build; the company has been pretty clear that it does not want to complicate its manufacturing lines by bringing in a wide array of body styles.

However, it seems necessary to have something larger that could help transport people to appointments when they cannot drive. For wheelchair accessibility, the Robovan, which was unveiled at the “We, Robot” event in October 2024, seems to be the most ideal solution:

Herdman did not indicate whether she was referring to the Robovan or if Tesla is building yet another body style that is geared toward full autonomy but also caters to the handicapped.

Tesla might need to develop something specifically for the handicapped in order to align with the Americans with Disabilities Act, which prevents discrimination against people with disabilities in transportation services. Uber was hit with a lawsuit late last year for “refusing to reasonably modify its policies, practices, or procedures where necessary to avoid discriminating against riders with disabilities.”

Tesla would obviously like to avoid this.

It will be interesting to see what Tesla will do with this project, and whether it will introduce something new to the market or just continue with the Robovan.
