SpaceX Starship test plans solidify after bad weather delays hop
Around the same time SpaceX was preparing for its 100th Falcon rocket launch, bad Texas weather forced the company to abort its second Starship hop test of the month.
Since that abort, SpaceX’s near-term Starship test plans have begun to solidify, offering a clearer picture of what to expect over the next week or two. Pending better weather at its Boca Chica, Texas test facilities, Starship serial number 6 (SN6) is still first in line and has been preparing for its hop debut ever since the prototype completed a Raptor engine static fire test on August 23rd.
Measuring approximately 30m (~100 ft) tall, SN6 is a full-scale Starship tank and engine section – the bottom ~60% and business end of the reusable orbital spacecraft. Of course, SpaceX has a ways to go before Starship is actually ready for its first orbital test flight, let alone reuse after such a test flight, but the company did take its biggest step yet towards that lofty ambitions with Starship SN5’s successful August 4th hop debut.
Effectively twins, Starship SN5 and SN6 have since been expected to take turns completing “several” hops to improve SpaceX’s familiarity with Starship launch operations and work towards a smooth procedure that can be completed multiple times per day. With SN6 now scheduled to hop no earlier than 8am CDT (UTC-5), September 3rd, 29 days after SN5’s debut, SpaceX still has its work cut out for it.
Nevertheless, SN5’s 150m (~500 ft) hop was the first flight of any kind for a full-scale Starship prototype, as well as the first use of an entirely new landing leg design and Raptor’s first flight in almost a year. In the history of rocket development, there is no precedent for launching and landing a prototype rocket and then repeating the same test with an entirely new prototype less than a month later.
Additionally, most of the 29 days since SN5’s first hop have been spent preparing Starship SN6 for a crucial “cryo proof” qualification test. Had that cryo proof been completed before SN5’s hop debut, SN6 could have been ready to fly as few as ~10 days later. That still leaves SpaceX a long ways away from multiple Starship hops per day but does offer encouragement that flight-proven Starship SN5 could be ready for its second hop not long after the pad is clear.
However, it appears that SpaceX instead plans to follow up SN6’s hop debut with a new ‘test tank’ meant to demonstrate an upgraded Starship “thrust puck” built out of a different steel alloy. Known as Starship SN7.1, the test will follow on the heels of a more traditional tank (SN7) that completed a record-breaking pressure test in June 2020 and proved that Starship would likely be better off with a different steel alloy.
While SN7 was a basic test tank (two domes and a few steel rings), SN7.1 adds a skirt section at its base and replaces the aft dome with a thrust dome. Likely built entirely out of a steel alloy closer to 304L than the 301 SpaceX has used for all prior Starship prototypes, that thrust dome features a new ‘thrust puck’ – the structural element Raptor engines attach to and transmit their thrust through.
Unlike past single tank tests, SN7.1 will be put through something more like a full prototype’s cryo pressure test. SN7.1 will be installed on a launch mount, allowing its skirt clamps to firmly secure the prototype to the stand, itself secured to a concrete slab on the ground. That launch mount also allows SpaceX to install a hydraulic ram designed to mechanically simulate the thrust of 1-3 Raptor engines without the risk involved in an actual static fire. SN7.1 is scheduled to begin testing no earlier than (NET) 8 am CDT (UTC-5), September 6th – just three days after SN6’s next planned hop attempt.

Tesla has updated its Robotaxi app so riders can pick which vehicle they want before they book. The latest in-app screens now show two options side by side: the two-seat Cybercab and the four-seat Model Y.
A screenshot circulating Thursday shows the change in practice. In Austin, a rider could choose a gold Cybercab for two people or a Model Y for four. Tesla’s updated description calls Cybercab “our first purpose-built autonomous vehicle,” designed for safety, accessibility, and comfort, and says the lineup is available only through the Robotaxi app.
Tesla has updated their Robotaxi page in the App Store. You’ll be able to select if you want a Cybercab or Model Y Robotaxi.

The distinction is more than cosmetic, and it’s important to note that Robotaxi refers to the platform, while Cybercab refers to a vehicle.
Model Y Robotaxis have carried the service since it opened in Austin in mid-2025 and later expanded to Dallas, Houston, and parts of Florida. Those vehicles are converted production SUVs that still have steering wheels and pedals.
Cybercab is different. It has no driver controls, butterfly doors, a low seat height meant to work with wheelchairs, extra trunk space for assistive devices, and braille on the handles. Tesla has registered dozens of the two-seaters with Texas regulators in the days leading up to its September 3 Austin event.
Giving riders a choice lets Tesla match the vehicle to the trip. Most rides involve one or two people, which is where Cybercab is meant to be cheaper and more efficient to operate. Groups of three or four, or anyone who needs more space, can still request a Model Y.
The same app handles booking, payment, cabin settings, and, on Cybercab, features such as phone-based door opening and in-cabin voice controls.
The update does not mean every city suddenly has both cars available. Cybercab support is listed for Austin first, and the purpose-built fleet is still small compared with the existing Model Y roster. Even so, the app change marks a shift from a single-vehicle pilot to a mixed fleet.
Riders can now choose between the compact, purpose-built robotaxi and the familiar SUV that launched the service.
Tesla Cybercab sightings are broadening far and wide, well outside of downtown Austin, Texas, with autonomy in focus as the company plans to launch the all-electric, two-seater this evening in the Lone Star State.
Tesla is set to launch Cybercab to a small group of people this evening in a dedicated event in Austin, Texas. Public details on the event are relatively slim.
However, Tesla’s focus on Cybercab falls well outside of the downtown Austin area and is expanding well across the United States as things continue to move quickly with the company’s autonomous efforts in 2026. Today, various images of Cybercab fleets in interesting locations have started to circulate.
The most notable is a fleet of at least 20 Cybercabs at Miami International Airport in Florida. Spotted last night, the fleet is expansive and is indicative of a looming release of Cybercabs once regulatory boxes are checked off.
Tesla has already been operating the Robotaxi platform in Miami for several months, but this Cybercab fleet at the airport could be joining the ride-hailing platform as approvals arrive:

Another fleet of Cybercabs was spotted at the Devon, PA showroom just outside of Philadelphia. We have seen several Cybercab units testing around the Philadelphia Metro Area, which is interesting considering Tesla does not have any active Robotaxi geofence in Pennsylvania.

Philadelphia would be an ideal location to test ride-hailing due to its dense tourist population, large, sprawling city layout, and to compete with other ride-hailing companies that operate in the city.
Expansive fleets of Cybercabs will be popping up in and around major cities throughout the rest of the year, if we were betting on it. Tesla has made it obvious that the Cybercab rollout will be aggressive and fast-paced, but within reason. Tesla is still prioritizing safety, so these testing phases will likely go on for some period of time before more members of the public are able to snag a Cybercab for a personal chariot.
The Tesla Model Y L is arguably the most hyped trim of the all-electric crossover, other than the Performance configuration that comes with white-knuckle speed and sports car-level handling.
However, it is not all perfect. Tesla owners in China who took delivery of the Model Y L, denoted with an L to highlight its longer wheelbase, are experiencing what they are referring to as “collapsing” of the rear wheels, as suspension issues appear to be an issue with some of the builds.

• Owners say the rear tire-to-arch gap shrinks after mileage or a full load. Some cases after about 9,000 km loaded. Others near 30,000 km

The gap between the wheel arch and tire has narrowed to the point that “not even a single finger” could fit, according to a report from Car News China. The failures are not tied to a specific mileage, as one owner said that after just 9,000 kilometers (5,600 miles), they noticed the suspension issue when their car was fully loaded.
Another one had the issue at 30,000 kilometers (18,640 miles) and noticed that the wheel gap shrank to two fingers, so not as drastic as the person who reported a similar issue at 9,000 km.
Tesla Model Y L is gaining momentum in China’s premium segment
Along with the visual recognition of the issue, others are saying the sagging is causing abnormal wear on the inside of the tires. Extra weight and instant torque already provide additional stress on the tires in electric vehicles during normal operation, so it is no surprise that this is another complaint.
There has been no recall issued by Tesla, and the company has not yet publicly acknowledged the issue.
Some are suggesting that owners use a “finger test” to self-diagnose whether there is an issue with the suspension. There should be four fingers between the tire and the wheel well; anything less than that starts to get dicey.
