Update: SpaceX has cancelled Thursday’s road closure, likely pushing Super Heavy’s first attempt at a static fire test into next week.

After an apparent false start on Wednesday morning, SpaceX has distributed a second safety alert among Boca Chica residents in anticipation of the first static fire of a Super Heavy booster as early as July 15th.

Delineated by highway and beach closures filed in advance with Cameron County, Thursday’s window stretches from 12pm to 8pm or 10pm CDT (UTC-5), giving SpaceX 8-10 hours to put the first functional Super Heavy booster prototype through its most challenging tests yet.

Known as a static fire, what is a mostly routine test for operational rockets is a bit more of a challenge for a first-of-its-kind prototype. Notably, on July 12th, Super Heavy Booster 3 survived its first ‘cryogenic proof’ pressure test, withstanding the thermal and mechanical stresses created when the rocket was filled with a few hundreds tons of liquid nitrogen and the expanding gases created as that cryogenic fluid then warmed and boiled. However, Booster 3 has yet to perform any kind of test involving the combustible, explosive liquid oxygen and methane propellant needed to fuel Raptor engines.

By all appearances, SpaceX aims to roll Super Heavy’s first wet dress rehearsal (WDR; like a ‘cryo proof’ with real propellant) and static fire into one busy day of testing. That combined WDR and static fire will likely be the first time ever that a launch vehicle as large as Super Heavy has attempted to pressurize its tanks autogenously, referring to the process of using a rocket’s own fuel and oxidizer to generate ullage gas. Starship prototypes notoriously struggled with their smaller autogenous pressurization systems – and jerry-rigged alternatives – on several occasions.

In other words, even an ignition-free wet dress rehearsal test completed with autogenous pressurization would be a major success and hurdle surmounted for Super Heavy. If SpaceX manages to perform the first booster WDR and static fire on the same day, it would indicate that the company has extreme confidence in Super Heavy.

Despite an aborted attempt on July 11th, SpaceX outfitted the rocket with one Raptor on Saturday, July 10th and installed another two engines in quick succession on Tuesday, July 13th – likely in an odd triangular configuration on the booster’s central nine-engine ‘thrust puck.’ Why that particular configuration was chosen instead of something more symmetric is unclear but it does decrease the odds of a multi-engine test on Super Heavy’s first static fire without a clear reason to assume that testing such an odd engine placement would provide some valuable insight.

In comparison, two engines on opposite sides of Super Heavy’s inner ‘ring’ or three engines forming a line across that ring are two configurations that boosters are very likely to use during landing burns. Regardless, according to Next Spaceflight’s Michael Baylor, SpaceX may start Super Heavy B3’s static fire test campaign with just one engine, so it’s not impossible that the current configuration is just a part of the incomplete process of installing five or more engines.

As with all Starship development, it’s equally likely that Super Heavy’s first wet dress rehearsal and static fire test attempts will slip late into the window, to Friday, or even to the week of July 19th. Stay tuned for updates!

Tesla pushes crazy ‘Luxe’ incentive package on flagship Model S and X

Tesla is pushing more customers to the Model S and Model X with a new incentive package.

Tesla has pushed a crazy new incentive package, known as the “Luxe Package,” on the flagship Model S and Model X, along with a $10,000 price increase on each trim level.

The move aims to likely bolster margins for the company on the two cars while also giving those who choose to buy the Tesla lineup mainstays a variety of awesome advantages, including Free Supercharging, Full Self-Driving, and other add-ons.

Tesla is offering a crazy Supercharging incentive on its two ‘sentimental’ vehicles

Last night, Tesla launched the “Luxe Package” for the Model S and Model X, which includes the following four add-ons:

  • Full Self-Driving (Supervised) – Your car will be able to drive itself almost anywhere with minimal driver intervention
  • Four-Year Premium Service – Wheel and Tire Protection, Windshield Protection, and Recommended Maintenance
  • Supercharging – Charge for free at 70,000+ Superchargers worldwide
  • Premium Connectivity – Listen to music, stream movies, monitor live traffic, and more – no Wi-Fi needed

Full Self-Driving is priced at $8,000. Free Supercharging for the life of the car is between $10,000 and $15,000 over the life of the vehicle, although Tesla has valued it at $5,000 in recent promotions.

Free Premium Connectivity is roughly $1,000, and the four-year tire, wheel, windshield, and maintenance plan is about $3,200.

In all, the value is over $25,000, but this is loosely based on usage.

The Model S and Model X are low contributors to Tesla’s overall sales figures, as they make up less than five percent of sales from a quarterly perspective and have for some time.

As they are certainly the luxury choices in Tesla’s lineup, the Model 3 and Model Y are the bigger focus for the company, as a significantly larger portion of the company’s sales is made up of those vehicles.

The Luxe Package is an especially good idea for those who drive high-mileage and plan to use the Model S or Model X for commuting or long drives. The free Supercharging makes the deal worth it on its own.

As for the price bumps, each of the vehicles are now priced as follows:

  • Model S All-Wheel-Drive: $94,990
  • Model S Plaid: $109,990
  • Model X All-Wheel-Drive: $99,990
  • Model X Plaid: $114,990

Tesla Roadster could have a formidable competitor with BYD’s 3000-HP supercar

The Roadster is one of the most anticipated vehicles of all time, especially because we’ve all had to wait so long for it. On its own, it will have a 1.9-second 0-60 MPH acceleration rate, which is projected to be better than the 2.3 seconds the U9 Track Edition will offer.

The Tesla Roadster is on the way, and yes, we know we’ve heard that for quite a few years. But when it comes, it might have a formidable competitor, and it might come from no one other than Chinese rival BYD.

BYD’s Yangwang U9 Track Edition is a new configuration of the U9 supercar that hit the Chinese Ministry of Information Technology (MIIT) database recently.

The vehicle was first spotted on the MIIT database by CarNewsChina. It will have a quad-motor powertrain, each dedicated to one wheel. Instead of the 1,287 horsepower that comes with the standard U9 configuration, the Track Edition will have 2,977.

There are only two cars that even come close in terms of horsepower: the Lotus Evija with 1,972 and the Rimac Nevera at 1,914 horsepower. The Tesla Roadster is expected to have somewhere around 1,000 horsepower.

The Roadster is one of the most anticipated vehicles of all time, especially because we’ve all had to wait so long for it. On its own, it will have a 1.9-second 0-60 MPH acceleration rate (without the SpaceX package, which brings the projection to 1.1 seconds), which is projected to be better than the 2.3 seconds the U9 Track Edition will offer.

The Roadster also beats the U9 Track Edition in projected top speed and range. The Roadster could top out at over 250 MPH, compared to the 217 conservative projection for the U9 Track Edition.

Range on the Roadster is 620 miles, beating 280 miles for the BYD.

The U9 Track Edition will also have some additional features compared to its base model. These include some aerodynamic additions, like a carbon fiber rear wing, diffuser, and an adjustable front splitter and adjustable rear wing.

The latter two are optional, but if you have enough scratch to drop on this car, you’re probably adding those two features as well.

We hope that both the Roadster and U9 Track Edition will hit a drag strip, road course, or even a superspeedway for some racing. It would truly be something for EV fans to drool over.

Tesla is breaking even its own rules to cap off an intense Q3

Tesla is pulling out all the stops to have a strong Q3 as the EV tax credit will phase out.

Tesla is breaking its own rules by advertising on various platforms in an effort to sell as many cars as possible before the end of the $7,500 electric vehicle tax credit.

Tesla has had a very polarizing perspective on advertising. Over the years, it has taken on different attitudes toward spending any money on marketing. It has instead put those dollars into research and development to make its vehicles more advanced.

Back in 2019, Tesla CEO Elon Musk talked about the company advertising its vehicles and energy products:

In 2021, in response to analyst Gary Black, who has pushed for Tesla to have a PR or marketing department, Musk said:

However, this did not hold as Tesla’s strategy for the long haul. While Musk did resist advertising for a long time, Tesla started placing ads on platforms like X, Google, and YouTube several years back. It’s pretty rare that Tesla pushes these ads, however.

The company’s stance on setting aside capital for advertising seems to be circumstantial. Right now, it is working to sell as many vehicles as it can before the tax credit comes to a close.

As a result, it is pushing some ads on YouTube:

It’s a move that makes sense considering the timing. With just six weeks roughly left in the quarter, Tesla is going to work tirelessly to push as many cars into customer hands as possible. It will use every ounce of effort to get its products on people’s screens.

Throw in one of the many incentives it is offering currently, and there will surely be some takers.
