The Tesla Semi’s economical advantage is frighteningly underestimated

The Tesla Semi has its own fair share of critics, and even today, some notable voices such as Microsoft co-founder Bill Gates believe that the Class 8 all-electric truck is not feasible. When one looks at the currently available information about the upcoming vehicle, however, one would see that the Tesla Semi is vastly underestimated. 

One of the key criticisms surrounding the Tesla Semi is its weight, which skeptics would claim is far too much to be economically viable. Tesla has not shared any specifics surrounding the Semi’s weight, though the company did note that the vehicle consumes less than 2 kWh per mile. As noted by the OBF in a YouTube video, this would translate to the Semi likely having a battery that’s roughly around 600 kWh to 1,000 kWh, depending on whether the vehicle features a 300 or 500-mile range.

Considering that Tesla’s 100 kWh batteries typically weigh around 1,300 lbs, it could then be inferred that the Semi’s battery pack would weigh around 7,800 to 13,000 lbs. This is assuming that the Semi is equipped with the same batteries that Tesla had when the Class 8 truck was unveiled. If Tesla’s 4680 cells are involved, this weight could be optimized further, considering that the company’s custom batteries are lighter and more powerful. 

Traditional diesel semitrailers typically weigh around 15,000 to 25,000 lbs, which means that the Semi would likely be at a disadvantage weight-wise. To address this disadvantage, Tesla would have to ensure that the rest of the Semi is made with light and durable materials. Tesla’s extensive experience as an EV maker plays a huge part in this, as the company could use all that it has learned during the design and rollout of the Model S,3,X,Y lineup to optimize the Semi’s weight. 

If Tesla’s estimates are correct and its new 4680 batteries are lighter, and if the electric car maker uses innovations such as a structural battery pack on the Semi, the weight disadvantage of the Class 8 truck against diesel rivals becomes much smaller. Couple this with the fact that the Semi’s electric motors weigh far less than a large diesel engine and the all-electric Class 8 long hauler becomes a very compelling alternative to traditional semitrailers. Even the Semi’s higher price, which is expected to start at $180,000, becomes a moot point considering that electric vehicles need far less maintenance over their lifetime. 

But this is not all. The Semi also stands to benefit from Tesla’s work with its Full Self-Driving suite, whose inner-city driving features are currently being rolled out to its initial batch of testers. Features such as Navigate on Autopilot, which would be incredibly useful for operators of the Tesla Semi, have already become refined over the years, and it would likely only take a matter of time before inner-city driving reaches the same state. When it does, capabilities that are unique to the Semi, such as its Convoy Mode, would likely become a “killer feature” that would make the vehicle a no-brainer against the competition.

SpaceX aces Starship’s 11th launch with success in every mission objective

SpaceX aces its eleventh Starship test launch on Monday evening, marking the company’s second consecutive takeoff that crossed off each of the planned mission objectives.

It was also the final launch of the V2 Starship rocket. The twelfth test flight will feature the larger V3 Starship rocket, followed by V4, which will eventually make the first trip to Mars.

The launch was overwhelmingly successful. In its 12th test flight, SpaceX was able to achieve every major mission objective, including the second successful deployment of Starlink satellite simulators and the relight of a Raptor engine while in space. The latter achievement demonstrated “a critical capability for future deorbit burns,” the company said.

The ship officially launched at 6:23 p.m. local time in Starbase, Texas, with all 33 engines igniting and sending the Ship to space.

Stage separation occurred just over eight minutes later, and Super Heavy started its descent back to the Gulf of America, where it successfully splashed down. The first part of the launch was complete.

Starlink simulators were deployed about twenty-one minutes after launch, as the Pez dispenser sent the faux-satellites out to space without any issue:

Perhaps the most anticipated part of the launch was with Starship’s banking maneuver and subsequent splashdown in the Indian Ocean.

Prior to Starship 11’s launch and successful re-entry and splashdown, SpaceX had lost a few vehicles during this portion of the previous flights.

However, the company had made tremendous improvements and has now aced two consecutive launches. On Monday, its approach and splashdown were both overwhelmingly successful:

The re-entry phase of this particular Starship launch aimed to gather data on the performance of the heatshield, SpaceX said. The heatshield was intentionally stressed to its limits to determine how much it could withstand without failing.

SpaceX will now turn its focus to the next vehicles, including V3, which is larger, more capable, and will help the company gather even more information about its launches into space:

CEO Elon Musk has said the third-generation Starship rocket will be built and tested by the end of the year.

Tesla has launched a new color at Gigafactory Berlin in Germany, home of the company’s “world-class paint shop,” as Elon Musk once called it.

Bringing a new color to Tesla’s Model Y, there are now five available colors for those who will receive a vehicle from Gigafactory Berlin, with four of them being colors offered in other markets.

However, there is now one distinct color that is only available in Germany: Marine Blue.

Priced at €1,300, Marine Blue will cost the same as both Diamond Black and Stealth Grey, while Quicksilver and Ultra Red are available for double the price.

It is the third shade of blue Tesla offers across its lineup, as Deep Metallic Blue and Glacier Blue are also offered, but in other markets.

Tesla has routinely flexed Giga Berlin for having the most advanced paint shop throughout its factories, and it has produced some interesting colors over the past few years, some of which were truly awesome.

Tesla Giga Berlin is getting a world-class paint shop, new color ‘layers’ to come

In 2020, Musk said, “Giga Berlin will have the world’s most advanced paint shop, with more layers of stunning colors that subtly change with curvature.”

He also detailed the company’s plans to upgrade the Fremont and Shanghai paint shops. Gigafactory Texas was not yet unveiled. Tesla has worked to improve those facilities, especially in Fremont.

It was able to roll out the new Diamond Black color earlier this year.

However, Giga Berlin seems to remain the standard in terms of paint for Tesla. It routinely offers new colors.

For example, back in 2022, Tesla rolled out its familiar Quicksilver color for the Model Y, while also introducing Midnight Cherry Red, a color close to burgundy. However, the company chose to discontinue the color after determining internally that customers no longer wanted to buy it.

Midnight Cherry Red was removed as an option earlier this year, likely to make way for the development of the new Marine Blue.

Tesla’s Autopilot visualization just got a big upgrade as the company added tons of new additions to what it will be able to render in terms of a vehicle’s surroundings.

The AP visualization shows up on the center touchscreen and illustrates the surroundings of the cars. It has gotten better in recent years, as it is able to outline types of vehicles, pedestrians, animals, and more.

Tesla just fixed a four-year-old bug with Full Self-Driving visualization

However, it still does not have every single application, and acquiring them will take some time. If an object or vehicle is visible to the vehicle but an accurate render is not available, the car will instead pick whatever is closest.

For example, I passed an Amish family yesterday in Lancaster, PA, and instead of illustrating the horse and carriage, it simply showed a small box truck.

In an effort to make the Autopilot and Full Self-Driving suites more robust and accurate, Tesla has added a substantial amount of vehicle renders, which will become available in the coming weeks.

The visualizations were found by Tesla hacker @greentheonly, who posted them on X.

The new visualization renders are:

  • Ambulance
  • Firetruck
  • Garbage Truck
  • Schoolbus
  • European Semi Truck
  • Golf Cart
  • Person on a Scooter
  • Person on a Skateboard
  • Stroller
  • Street Sweeper
  • Three-Wheeler
  • Trailer
  • Train
  • Tram
  • Person in a Wheelchair

Here is an image with all of the Autopilot visualization renders:

The visualization is a crucial part of manual operation and can be considered a distinct advantage that Tesla has over other companies.

It continues to be an effort that Tesla invests heavily in, as it keeps refining the suite and making it more robust with additional visualizations and animations.

Recently, it was revealed that Tesla is planning to utilize Unreal Engine for driver visualization to create a realistic depiction of the vehicle’s environment. Tesla has not yet confirmed this, but coding found with the Model S and Model X showed it could be coming in the near future.
