Tesla emphasizes factory safety, preempts possible smear campaign by auto union

Published

on

Tesla released a blog post Sunday evening that reemphasizes the company’s goal to become the safest auto factory in the world. The post comes after the United Auto Workers Union (UAW) attempted to rally support earlier this year from Fremont factory workers in favor of unionizing.

Tesla states that it has received several media inquiries over allegations about safety at its Fremont, California factory. The well-timed nature of the inquiries, and similarity in topic, led Tesla to believe that the UAW was spreading anti-Tesla propaganda to the media in an attempt to provoke a response from the public, and from Tesla employees. In typical fashion, Tesla acted quickly and took to the offensive to defend the company’s approach to manufacturing, and maintaining the health and safety of its employees. The company has gone as far as forming dedicated Ergonomics Teams that have exclusive focus on “improving health and safety and reducing ergonomic risk for current and future production”.

“We are building entirely new vehicles from the ground up, using entirely new technology, production, and manufacturing methods, and ramping them at high volume. Getting this right is extremely difficult, and we deeply appreciate the hard work that all our employees do to help us achieve what most regard as impossible.” says Tesla through its blog post.

Tesla notes that in just 15 years, the company has become the largest manufacturing employer in California with over 10,000 production jobs in the Fremont factory and surrounding Bay Area.

Tesla has a proven track record of putting safety first as made evident by the award-winning safety ratings for its Model S and Model X. Vehicles have taken the brunt of the impact for their occupants, have swerved to avoid accidents and have even accelerated to avoid accidents. The innovative safety features Tesla has built into its vehicles is unsurpassed in the automotive world.

Though Tesla’s safety record to date is already better than industry-average, according to its press release, the company indicates that it continues to learn and apply new production processes aimed at improving employee well-being. Among the improvements are:

  • Added 3rd shift to the manufacturing schedule to cut overtime because the employees asked for it and it was the right thing to do.
  • Hired dedicated Ergonomist and established an Ergonomics team to ensure that current and future Tesla manufacturing lines are ergonomically friendly for employees.
  • Model 3 has been designed with manufacturing employee ergonomics in mind. The Tesla Ergonomics Team works closely with design and engineering teams to catch ergonomics issues before they happen and proactively drive these improvements back into the design of the equipment and the car. Yes, you heard that right. Tesla will redesign the car if it is resulting in ergonomically challenging situations for its manufacturing employees.
  • Established safety teams in every department which meets regularly to ensure safety is a top focus in its manufacturing operating departments.

These changes are not just skin deep and the company is seeing the results of the changes already. Tesla says it has collectively reduced 52% in lost time incidents and a 30% reduction in recordable incidents in the first quarter of 2017 versus the same period last year. These more granular metrics support an improvement in the industry standard Total Recordable Incident Rate (TRIR) which at the end of Q1 2017 was 4.6, a full 32% better than the industry standard of 6.7.

Anyone who has worked in an industry where safety is important can tell you that a culture of safety awareness is built day by day, month by month over many years. Tesla has a demonstrated history of superior results. The steps it has outlined to drive further improvements at the factory are evidence of a continued focus on safety and its employees.

The full post from the Tesla Blog reads as follows:

Creating the Safest Car Factory in the World

Earlier this year, the United Automobile Workers (UAW) announced it was attempting to organize workers in Tesla’s Fremont factory. The latest phase of their campaign involves a concerted and professional media push intended to raise questions about safety at Tesla.

We have received calls from multiple journalists at different publications, all around the same time, with similar allegations from seemingly similar sources about safety in the Tesla factory. Safety is an issue the UAW frequently raises in campaigns it runs against companies, and a topic its organizers have been promoting on social media about Tesla.

Some of the publications who have contacted us have rejected covering this “story” because they understand it is a misleading narrative based on anecdotes, not facts. However, there will likely be a few publications that choose to publish stories regardless, so we want to make sure the public also has the facts. Watch for these articles to downplay or ignore our actual 2017 safety data and to instead focus on a small number of complaints and anecdotes that are not representative of what is actually occurring in our factory of over 10,000 workers.

First, some context is important. The difficulty of starting a successful U.S. car company cannot be overstated, as evidenced by the fact that Ford is the only other U.S. car company to have never gone bankrupt. We are attempting to break this trend in order to fulfill our mission of accelerating the world’s transition to sustainable energy.

We are building entirely new vehicles from the ground up, using entirely new technology, production, and manufacturing methods, and ramping them at high volume. Getting this right is extremely difficult, and we deeply appreciate the hard work that all our employees do to help us achieve what most regard as impossible. While we still have a long way to go, in less than 15 years, we have become California’s largest manufacturing employer, creating more than 10,000 high-quality production jobs in the Bay Area, many of which had previously disappeared with the closure of NUMMI under the stewardship of the UAW.

As we work to achieve our mission, nothing is more important to us than protecting the health and safety of our employees. As we look at our safety record in prior years, we realize that we have not been perfect. No car factory is perfect, but particularly given that Model S and X were the first cars we built at more than tiny volumes, we fully acknowledge that they were not designed for ease of manufacturing – far from it. As would be expected, we have since learned many lessons, including how to improve the production process for the well-being of our colleagues.

Here are just some of the improvements that we have made:

  • Historically, depending on production needs, some Tesla employees have worked significant amounts of overtime because it was necessary for the company to survive. However, working overtime can be challenging for employees and their families. Last year, we added a third shift to reduce the overtime burden on each team member and to improve safety. We did this because our employees asked for it, and because it was the right thing to do.
  • As a result of this change, the average amount of hours worked by production team members has dropped to about 42 hours per week, and the level of overtime decreased by more than 60%. We hired our first dedicated Ergonomist in 2013, and in 2015 established an Ergonomics Team exclusively focused on improving health and safety and reducing ergonomic risk for current and future production.
  • In addition to improving the process of building Model S and X, Model 3 has been designed specifically with ergonomics in mind. Our ergonomics team has worked hand-in-hand with our engineers on the design process. As just one example, we created simulations that showed us where reaching or bending by employees was most likely to occur, which in turn allowed us to redesign the equipment and the car to eliminate these issues as much as possible.
  • Each department now has a Safety Team that meets regularly to increase safety awareness and recommend improvements, many of which have already been implemented.
  • We are continuing to establish health and safety management procedures to scale with our operational growth.

The third shift, ergonomic improvements and increased safety awareness have collectively led to a 52% reduction in lost time incidents and a 30% reduction in recordable incidents from the first quarter of 2016 to the first quarter of 2017. In addition, through the end of Q1 2017, the factory’s total recordable incident rate (TRIR), the leading metric for workplace safety, is 4.6, which is 32% better than the industry average of 6.7. This data shows that there has been a dramatic improvement in employee safety, we are now significantly better than industry-average, and we continue to improve each day. A few anecdotes in a factory of over 10,000 people can always be given, but these are the facts.

Tesla’s safety record is much better than industry average, but it is not enough. Our goal is to have as close to zero injuries as humanly possible and to become the safest factory in the auto industry. We will get there by continuing to ask our employees to raise safety concerns and to keep proposing ideas that make things even better.

The alternative is to stop improving and to instead do what the rest of the industry, including the UAW, has always done. But being industry average would make our safety 32% worse. We care too much about our team to go backwards.

Tesla has a Cybercab problem nobody saw coming

Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.

Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”

Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.

The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.

Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.

The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.

Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

Published

on

Credit: SpaceX

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.

Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.

This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.

This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.

Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.

Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.

The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.

Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.

For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.

Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla Assisted Driving expands to tenth EU country

Published

on

Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.

Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.

The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.

Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.

In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.

Tesla starts showing how FSD will change lives in Europe

The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.

The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.

These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.

However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
