After a handful of days as an impressive monolith stood along the coastal wetlands of Texas, SpaceX technicians have once again separated the nose and tail sections of the first Starship prototype to allow additional integration and assembly work to continue. The craft’s three Raptors were also removed and stored nearby, shown to be barebones facsimiles standing in for flightworthy hardware that could arrive in the next month or two.

Up next, three or four propellant tank domes – currently being assembled and welded together on-site – will likely be installed inside the steel hull of the giant Starship prototype’s aft barrel section. Known as bulkheads, the installation of those tank domes will bring SpaceX one step closer to performing hop tests of the simultaneously bizarre, confusing, and beautiful craft.

At this point in time, it appears that Starhopper is some odd combination of showmanship and actual hardware meant to test certain aspects of the first orbital Starship build, said to be complete as early as June 2019 by CEO Elon Musk. In the last week or so, SpaceX technicians attached and welded over Starhopper’s two sections – an aft barrel with legs and Raptors and a conical nose – and even did a sort of photoshoot, removing an on-site fence for a photo that Musk later shared while stating that the vehicle had “completed assembly”.

One could argue that assembly is not exactly complete if the given product has to be pulled in half to install significant new components. Regardless, the external skin, aft barrel section, and rough landing legs do appear to be more or less complete from a very basic structural perspective, although there is clearly much work still to be done if the vehicle’s tank bulkheads haven’t been installed. Aside from completing the liquid oxygen and methane tank structure, SpaceX engineers and technicians will additionally have to complete the vehicle’s aft section, a massive 9m/30ft-diameter thrust structure capable of supporting the thrust of three Raptor engines and the weight of the entire fueled rocket. After that, plumbing, avionics, sensors, attitude thrusters, and more will still need to be completed and integrated.

If Starhopper’s nose section is largely a nonfunctioning aerodynamic shroud and propellant tanks will be primarily located inside the aft section, the fuel and oxidizer capacities of the vehicle’s tanks can be roughly estimated. Assuming a 9m/30ft diameter, the aft barrel stands around 13m/43ft tall. Assuming that the upper tank dome will reach a meter or two above the steel cylinder and that the aft Raptor thrust structure is also roughly 1-2 meters deep, Starhopper would have a total tank volume around 830 m3 or almost 30,000 cubic feet (~225,000 gallons), potentially 1000 metric tons of fuel or more if fully loaded.

Perhaps less than coincidentally, SpaceX already has liquid methane and oxygen tanks on-site (one is pictured above) with more than enough capacity to meet Starhopper’s potential propellant needs. However, it’s worth noting that current plans (and permissions) only show Starhopper traveling as high as 5km on flights that will last no more than 6 minutes, and CEO Elon Musk has indicated in no uncertain terms that the prototype will remain distinctly suborbital and is primarily focused on fleshing out Starship’s vertical take-off or landing (VTOL) capabilities before SpaceX proceeds to much more aggressive tests.

While it would be safe to take his schedule with many dozens of grains of salt, Musk noted last week that the first orbit-ready Starship could be finished as early as June 2019, while he expects Starhopper tests to begin as early as February or March. Where exactly that orbital Starship and its Super Heavy booster partner will be built is now much less clear after SpaceX has reportedly canceled a berth lease and thus its plans to build a BFR factory in the Port of Los Angeles. Will SpaceX build a BFR factory in Texas or will it build the orbital Starship en plein air like its Starhopper predecessor? And Super Heavy? Where will all three conduct static fires, hops, or launches from?

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.
