For the second time in less than five weeks, SpaceX has also transported a brand new Starship booster (known as Super Heavy) from its Boca Chica factory to a launch site and testing facilities just down the road.

This time around, though, the Super Heavy in question (Booster 4) is expected to be the first truly flightworthy booster and – though plans could change – has been assigned to Starship’s first orbital test flight (OTF). In a show of force, Booster 4 left the high bay it was built in and rolled to a nascent orbital launch site with 29 Raptor engines installed after an almost unbelievable feat of rocket assembly just one day prior.

In as few as 14 hours, SpaceX installed all 29 of Super Heavy Booster 4’s Raptor engines, including 20 “boost” variants (RB) and 9 gimballing “center” variants (RC). It’s unlikely that there is a single other instance in the history of spaceflight where so many large, functional rocket engines were installed as quickly as SpaceX was able to outfit Booster 4. Though signs suggest SpaceX will likely remove some or all of those engines after installing the rocket booster at the launch pad and beginning proof testing, the feat is still an extraordinary one.

Now, mere hours after SpaceX rolled Booster 4 to the orbital launch site, Musk has revealed that the company more or less simultaneously outfitted Ship 20 – the first orbital-class Starship prototype – with all six of its Raptor engines in yet another ‘first’. Prior to Ship 20’s milestone, SpaceX had never installed more than three Raptor engines on a Starship prototype and never even attempted to install a single Raptor vacuum engine. Orbital ships will have three gimballing Raptors optimized for sea level and three fixed engines optimized for vacuum – necessitating a far larger bell nozzle.

Likely capable of producing more than 1250 metric tons (~2.8M lbf) of thrust in vacuum, the installation of those six engines likely also makes Starship S20 the most powerful orbital rocket stage ever assembled. Of course, like Booster 4, these engines will likely be removed for crucial proof testing and will need to be reinstalled for static fire tests or launch, but the fact remains that those milestones are just a matter of time (and a few tests) away from becoming reality.

If no major surprises pop up during qualification testing, Booster 4 and Ship 20 will be joined together to become the first full Starship ‘stack’ and are also expected to support the program’s first orbital launch attempt later this year.

Tesla Cybercab uses a unique strategy for picking up the right rider

Tesla Cybercab is using a unique strategy for picking up the correct rider, which is a crucial part of ride-hailing to ensure people end up in the right place and are charged the correct price.

Cybercab will utilize an RGB strip in its front light bar that will illuminate in a variety of different colors to mark itself.

This identifying mark will also appear in the Robotaxi app, giving riders in the same location a notable distinction in an effort to avoid any confusion regarding who should get in each vehicle.

Other ride-hailing services use similar strategies: Lyft and Uber rides are recognizable through driver identity, vehicle type and color, as well as license plate. Waymo will display the rider’s initials on top of the vehicle, letting them know that the specific vehicle for them has arrived.

Tesla’s strategy is unique and interesting, but there are some flaws. Cybercab’s main purpose is aimed toward being an autonomous ride for all, including those who have disabilities like being blind or even color blind.

Tesla will likely have something in the pipeline for those who cannot see colors or have limited vision. There will definitely be multiple ways to identify which vehicle is the one that “you” specifically ordered.

Cybercab is set to start giving public rides next Thursday, September 3, in Austin, as it announced a dedicated event last week and invited many members of the Tesla community.

Additionally, members of the public will be invited as well. Tesla has been offering employee rides in Cybercab for nearly two months.

Tesla ends in-house wrap service that always seemed like a short-term program

Tesla has said goodbye to one customization option for its vehicles: the wrap service it launched several years ago.

After launching an in-house wrap service in August 2020 for the first time in China. In the U.S., it launched in October 2023. Tesla continued to expand the program and adjust it with better pricing and fewer options for the Cybertruck.

By December 2023, it was giving owners of the Model 3, Model Y, and the Cybertruck the opportunity to give their vehicle a fresh look with a vinyl wrap.

It was only available in five locations: Costa Mesa, Oceanside, Santa Clara, West Covina, all in California, and Seattle, Washington.

However, Tesla made some big adjustments to its shop, and the wrap service is officially gone:

Wraps are very popular across the Tesla lineup, especially since the company offers relatively few colors. Many choose to wrap their Teslas with interesting colors, patterns, or even finishes, turning their cars from glossy to satin or matte.

However, Tesla’s wrap service was so limited geographically that it never really had a chance to get off the ground or compete with local shops. Every area in the United States is now overflowing with detailing shops, mobile detailers, and other automotive specialists, many of whom perform wrap services.

Tesla’s service was confined to the Pacific time zone and only spanned across two states. It was never going to be something Tesla was a major competitor in, nor was it going to disrupt the wrapping industry. Now that the program has ended, it seems pretty ideal to believe it was always going to be a short-term thing.

Along with the wrap service, Tesla removed several other products, but nothing too crazy. The Model 3 Door Pocket and Cupholder Liners, the Model S 19″ Magnetite Wheel and Winter Tire Package, Model X/Y Ski/Snowboard Carrier for Hitch Rack, Tesla’s Electric Summer Party Tee, and the Electric Summer Tee were the other items the company totally eliminated from its online shop.

Tesla Robotaxi fleet gets a brain upgrade ahead of Cybercab launch event

Tesla’s Robotaxi service now runs longer hours nationwide as its unsupervised fleet quietly grows larger.

Published

Tesla’s Robotaxi service just got easier to catch, with the company’s official Robotaxi account noting that rides are now available from 6 a.m. to 10 p.m., seven days a week, across its operating footprint. The account also said its unsupervised fleet is “a lot bigger” than before, though without specifics. The bigger change is what Tesla says upgraded intelligence in vehicle distribution and routing is what’s actually cutting wait times, not a new Full Self-Driving version.

While Tesla did not name the team behind the upgrade, the language points to its AI and fleet software group rather than the driving stack itself. Vehicle distribution and routing in Robotaxi has functioned mostly as a dispatch problem with the software deciding which idle car goes to which rider, and how far it has to travel to get there. “Upgraded intelligence” suggests a smarter version of that dispatch logic, likely using demand forecasting to position idle cars near where riders are about to request them rather than reacting once a request comes in. Tesla’s AI division has built similar prediction systems for other parts of the business, including the neural networks that power FSD itself, so applying that same approach to fleet logistics would be a natural extension rather than a new discipline for the team.

Tesla is also about a week away from a separate robotaxi milestone. The company plans to launch Cybercab, its purpose built two seat robotaxi with no steering wheel or pedals, in Austin on September 3. Cybercab has been giving employees rides on public and private roads for weeks, and the September event is expected to fold those vehicles into the existing Robotaxi fleet within days of the launch.


Austin previously ran Robotaxi from 6 a.m. to 2 a.m. as of last September, a schedule set before the service expanded into Dallas, Houston, Miami, Tampa, Orlando and the Bay Area. Wednesday’s post did not specify whether that extended overnight window still applies in Austin specifically or whether 6 a.m. to 10 p.m. is now the standard across every market. Tesla’s post, visible on its official Robotaxi account, framed the change simply as fewer riders waiting around for a car.

Whether the wider hours hold once Cybercab enters the fleet next week is the next thing worth watching. Tesla has tended to expand Robotaxi in increments, first geofence, then hours, then fleet size, and each step so far has arrived without much advance notice.
