A day after revealing the completion of the 200th Falcon upper stage and Merlin Vacuum engine, SpaceX has announced that it also recently finished building Starship’s 200th upgraded Raptor engine.

Starship – and Raptor, by extension – has yet to reach orbit and is likely years away from scratching the surface of the established success and reliability of the Falcon upper stage and MVac. But compared to MVac, Raptor is more complex, more efficient, more than twice as powerful, experiences far more stress, and is three times younger.

And Raptor 2 isn’t the first version of the engine. Before SpaceX shipped its first Raptor 2 prototype, it manufactured 100 Raptor 1 engines between the start of full-scale testing in February 2018 and July 2021. By late 2021 or early 2022, when Raptor 2 took over, the total number of Raptor 1 engines produced likely reached somewhere between 125 and 150 – impressive but pale in comparison to SpaceX’s Raptor 2 ambitions.

From the start, Raptor 2’s purpose was to make future Raptors easier, faster, and cheaper to manufacture. The ultimate goal is to eventually reduce the cost of Raptor 2 production to $1000 per ton of thrust, or $230,000 at Raptor 2’s current target of 230 tons (~510,000 lbf) of thrust. As of mid-2019, Musk reported that each early Raptor 1 prototype cost “more” than $2 million for what would turn out to be 185 tons of thrust (~$11,000 per ton). It’s not clear if that ever appreciably changed.

In response, SpaceX strived to make Raptor 2 simpler wherever possible, removing a large part of the maze of primary, secondary, and tertiary plumbing. In 2022, CEO Elon Musk confirmed that SpaceX had even removed a complex torch igniter system for Raptor 2’s main combustion chamber. All that simplification made Raptor 2 much easier to build in theory, and SpaceX’s production figures have more than confirmed that theory. Despite those simplifications, SpaceX was also able to boost Raptor 2’s thrust by 25% by sacrificing just 1% of Raptor 1’s efficiency.

Beginning with its first delivery in February 2018, SpaceX produced the first 100 Raptor 1 engines in about 36 months. In the first 11 to 12 months of Raptor 2 production, SpaceX has delivered 200 engines. That translates to at least six times the average throughput, but the true figure is even higher. In June 2019, Musk stated that SpaceX was “aiming [to build a Raptor] engine every 12 hours by end of year.” As is usually the case, that progress took far longer to realize. But in October 2022, a senior NASA Artemis Program official revealed that SpaceX recently achieved sustained production of one Raptor 2 engine per day for a full week.

Such a high rate – likely making Raptor one of the fastest-produced orbital-class rocket engines in history – is required because SpaceX’s next-generation Starship rocket needs a huge amount of engines. The Starship upper stage currently requires three sea-level-optimized Raptors and three vacuum-optimized Raptors, and SpaceX has plans to increase that to nine engines total. Starship’s Super Heavy booster is powered by 33 sea-level Raptors.

Orbital-class versions of Starship and Super Heavy have never flown, let alone demonstrated successful recovery or reuse, so SpaceX has to operate under the assumption that every orbital test flight will consume 39 Raptors. Even after the reuse of Super Heavy boosters or Starships becomes viable, taking significant strain off of Raptor demand, SpaceX wants to manufacture a fleet of hundreds or even thousands of Starships and a similarly massive number of boosters. To outfit that massive fleet, SpaceX would have to mass-produce orbital-class Raptor engines at a scale that’s never been attempted.

But it will likely be years – if not a decade or longer – before SpaceX is in a position to attempt to create that mega-fleet. If the Raptor 2 engines SpaceX is already building are modestly reliable and reusable, and it doesn’t take more than 5-10 orbital test flights to begin reusing Starships and Super Heavy boosters, a production rate of one engine per day is arguably good enough to support the next few years of realistic engine demand.

SpaceX’s first orbital Starship launch attempt could occur as early as December 2022, although Q1 2023 is more likely. SpaceX currently has permission for up to five orbital Starship launches per year out of its Starbase, Texas facilities and will likely try to take full advantage of that with several back-to-back test flights in a period of 6-12 months.

Kia gains Tesla Supercharger access and issues a big apology

Kia gained Tesla Supercharger access and respect from Tesla fans in the same day.

Kia EV6, EV9 and Niro Owners Gain Access to Over 21,500 Tesla Superchargers

Kia has announced that owners of the EV6, EV9, and Niro EVs have officially gained access to over 21,500 Tesla Supercharger locations in North America.

However, its announcement also contained an apology to Tesla.

First, Kia said that its three EV offerings will have access to Tesla’s expansive Supercharger Network. More than 40,000 DC fast chargers are available to Kia EV drivers, a major uptick as Tesla Supercharger access nearly doubles the number of accessible piles.

Sean Yoon, President of Kia North America and Kia America, said:

“Kia is committed to an exceptional ownership experience, and expanding the network of available DC fast chargers to our EV customers is an important component to maintaining the brand’s leadership in electrified mobility. Now, with access to the Tesla Supercharger network of DC fast chargers, our EV owners can feel even more confident in their decision to purchase or lease a fully electric Kia vehicle.”

Kia owners who have a CCS1 Charging Port will have access to an NACS adapter through dealerships. This will enable compatibility, as current inlets are not NACS, the port that Tesla utilizes.

However, Kia will eliminate the need for this adapter starting with the 2025 EV6 and 2026 EV9. These will come standard with NACS inlets.

We mentioned Kia included somewhat of an apology to Tesla, which is related to social media posts from “certain Nordic distributors,” as the company puts it:

Kia said in its announcement:

Kia America is aware of marketing posts by certain Nordic distributors. These initiatives were developed entirely independently by those distributors, without direction from Kia AmericaKia Europe or Kia Global. We want it to be clear that these posts do not reflect the position of Kia America, and we remain committed to clear and professional communication that reflects our values.”

The company also said that it “condemns the recent attacks that disrupt the availability of convenient and affordable charging for our customers.”

Tesla adds new child protection feature to mobile app

Tesla is rolling out within its mobile app a new feature that aims to save the lives of those forgotten in the car.

Tesla is bolstering its in-car safety system with the addition of a new feature that aims to protect children left in the vehicle, an extension of a feature it introduced with the addition of 4D radar systems.

Children are, unfortunately, victims of accidents even when a vehicle is not in motion. A report from 2024 noted that 37 children under the age of 15 die each year because they are left in cars, usually dying from heatstroke.

Tesla has made a few attempts to eliminate the possibility of this happening. Back in September, coding from Software Update 2024.32 noted that the company would be using an alert system to warn people of children left behind:

Tesla set to roll out new child safety and navigation features, coding shows

This was enabled by the use of a wave sensor within the cabin, a piece of tech Teslarati found in a filing back in 2021 with the FCC.

The entire idea behind this addition to the vehicles was to alert owners if there were passengers left in the car.

Now, Tesla is adding another level of this to its mobile app, according to a decompile of the Version 4.44.0 update, which is rolling out to customers now.

Tesla App Updates on X revealed a “Child Left Alone Detection” feature in the new app version, which has a few strings from a software perspective:

  • Cannot turn off climate when Child Left Alone Detection is active
  • Climate failed to start. Climate is unavailable when Child Left Alone Detection is active.
  • Climate controls are disabled when Child Left Alone Detection is active
  • Unable to start software update while a child is detected in your vehicle

It appears that, if the vehicle detects a child or another occupant in the car, climate controls will be disabled through the app in an attempt to maintain a proper cabin temperature. Turning the temperature up or even turning climate control off from the app will not be possible.

This is a major update to this feature as it only bolsters the safety of the occupants in the event that they are left behind. Of course, many of us might ask, “How do you leave a child in the car?”

However, it happens, as past events have shown, and this is a great way to eliminate it from happening in Tesla vehicles.

Tesla FSD ruins other intelligent driving systems for NIO Superfan influencer

“Since I drove FSD, I have been disenchanted with all the ‘driving assistance’ of domestic brands,” Lee wrote.

Tesla Full Self-Driving (FSD) has been making waves in China, with owners pushing the system to its limits on what appears to be a regular basis. Videos of Tesla drivers in China show FSD navigating the trickiest of roads, from busy city streets to narrow, unpaved paths in rural areas.

And as per an influencer and NIO superfan, FSD is ruining other driver-assist systems from other automakers in China.

FSD Ruins It For Influencer

China-based influencer and NIO superfan Andy Lee recently shared his thoughts about FSD on social media. As per Lee, Chinese intelligent driving systems are overhyped by marketing. But once he personally experienced FSD’s capabilities, he became disillusioned with the offerings of domestic carmakers.

“Since I drove FSD, I have been disenchanted with all the ‘driving assistance’ of domestic brands. I once thought that the ‘driving assistance’ of domestic brands could beat FSD in seconds, but it seems that I was wrong. Not only did they fail to outperform FSD, they were actually crushed in reverse,” Lee wrote in his post.

FSD could very well become Tesla’s moat since even cars that are equipped with the same hardware would not be able to perform similarly unless they have access to the company’s training data and software. Tesla’s fleet is ever-growing as well, which means that FSD will only get better over the years.

Unsupervised on the Horizon

Tesla is already using FSD Unsupervised for its vehicles that are produced in the Fremont Factory and Gigafactory Texas. As per Elon Musk during the Q1 2025 earnings call, he expects Tesla to be able to roll out FSD Unsupervised to consumers before the end of this year. He also highlighted that Tesla is being extremely careful with FSD Unsupervised’s rollout.

“Before the end of this year. Not necessarily — I say within the U.S., like we do want to test — at Tesla, we’re absolutely hardcore about safety. We go to great lengths to make the safest car in the world and have the lowest accidents per mile in. 

“So we want to be very careful. We want autonomy to be definitively safer than manual driving. So it’s not enough that it just be as safe. It needs to be meaningfully safer than if the car’s manually driven,” Musk stated.
