Tesla patents ‘fibrous foam architecture’, hinting at new seating material and interior trim to come
Tesla has submitted a patent application for a “fibrous foam architecture” with claims that the manufacturing technique for seats and interior trim would create a more efficient and environmentally-sustainable process.
The submitted patent explains that the current materials used for cushioning in traditional vehicle seats include foam made from polyurethane, a material that is not able to be recycled and may not be the most comfortable due to its lack of breathability. Manufacturing the foam is also a time-consuming and laborious process that involves the pouring and mixing of numerous chemicals, like polymer or epoxy, into a mold. After setting, this requires additional material to be trimmed and shaped, thereby creating unnecessary waste that Tesla’s fibrous foam architecture hopes to eliminate.
The background of the patent states, “Trim to foam assembly may include hog ring, hook and loop, and/or clipping methods. In such methods, alignment tolerances may need to be maintained, mating surface limitations may need to be met, trenches and stitches may need to be provided and so on. Glue application storage and handling may also be required. Current manufacturing processes may be labor-intensive and time-consuming.” This would improve the production and quality of backrests, armrests, leg-rests, and bolsters.
Tesla is looking to improve upon its vehicle’s interior, as it suggests “there is a need for an improved foam architecture and associated manufacturing process that overcome the aforementioned drawbacks.”
An improved foam structure for vehicle seating will provide a new, more comfortable, recyclable material for owners of Tesla electric cars. Tesla plans to use the stacking of multiple layers of different materials to make a less-laborious and more cost-effective seating option. The use of sustainable materials that can be recycled after use will appeal to the environmentally-conscious Tesla owner. The company unveiled 100% cruelty-free seat options in 2017 to its Model S and Model X, and would later offer the 100% vegan material for the Model 3 and the upcoming Model Y.
Tesla has continued to improve its vehicles in every way imaginable for its customers through OTA power updates and accessibility features while finding efficiencies in its design and manufacturing process to support a wider scale-out in production. The company is gearing up for the initial production of the Model Y in early 2020 and the first mass-production of the Model 3 from its Shanghai-based Gigafactory 3. Tesla announced during the Q3 earnings call, “trial production of Model 3 in Shanghai has begun, ahead of schedule. We are also ahead of schedule to produce Model Y and now expect to launch by summer 2020. Model Y equipment installation is underway in advance of the planned launch next year. We are moving faster than initially planned, using learnings and efficiencies gained from our Gigafactory Shanghai factory design.”
As Tesla begins to increase the rate of production of its fleet of vehicles, efficiency is a key factor in creating a lean and cost-effective manufacturing process. Tesla is set to begin production of the Model Y crossover in 2020 and will unveil its highly-anticipated Cybertruck on November 21.

Tesla Cybercab tests are going on overdrive with production-ready units
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the vehicle being reported across social media this week.
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the autonomous two-seater being reported across social media this week. Based on videos of the vehicle that have been shared online, it appears that Cybercab tests are underway across multiple states.
Recent Cybercab sightings
Reports of Cybercab tests have ramped this week, with a vehicle that looked like a production-ready prototype being spotted at Apple’s Visitor Center in California. The vehicle in this sighting was interesting as it was equipped with a steering wheel. The vehicle also featured some changes to the design of its brake lights.
The Cybercab was also filmed testing at the Fremont factory’s test track, which also seemed to involve a vehicle that looked production-ready. This also seemed to be the case for a Cybercab that was spotted in Austin, Texas, which happened to be undergoing real-world tests. Overall, these sightings suggest that Cybercab testing is fully underway, and the vehicle is really moving towards production.
Production design all but finalized?
Recently, a near-production-ready Cybercab was showcased at Tesla’s Santana Row showroom in San Jose. The vehicle was equipped with frameless windows, dual windshield wipers, powered butterfly door struts, an extended front splitter, an updated lightbar, new wheel covers, and a license plate bracket. Interior updates include redesigned dash/door panels, refined seats with center cupholders, updated carpet, and what appeared to be improved legroom.
There seems to be a pretty good chance that the Cybercab’s design has been all but finalized, at least considering Elon Musk’s comments at the 2025 Annual Shareholder Meeting. During the event, Musk confirmed that the vehicle will enter production around April 2026, and its production targets will be quite ambitious.

Tesla gets a win in Sweden as union withdraws potentially “illegal” blockade
As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Swedish union Vision has withdrawn its sympathy blockade against Tesla’s planned service center and showroom in Kalmar. As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Vision’s decision to pull the blockade
Vision announced the blockade in early December, stating that it was targeting the administrative handling of Tesla’s facility permits in Kalmar municipality. The sympathy measure was expected to start Monday, but was formally withdrawn via documents sent to the Mediation Institute and Kalmar Municipality last week.
As noted in a Daggers Arbete report, plans for the strike were ultimately pulled after employer group SKR highlighted potential illegality under the Public Employment Act. Vision stressed its continued backing for the Swedish labor model, though Deputy negotiation manager Oskar Pettersson explained that the Vision union and IF Metall made the decision to cancel the planned strike together.
“We will not continue to challenge the regulations,” Petterson said. “The objection was of a technical nature. We made the assessment together with IF Metall that we were not in a position to challenge the legal assessment of whether we could take this particular action against Tesla. Therefore, we chose to revoke the notice itself.”
The SKR’s warning
Petterson also stated that SKR’s technical objection to the Vision union’s planned anti-Tesla strike framed the protest as an unauthorized act. “It was a legal assessment of the situation. Both for us and for IF Metall, it is important to be clear that we stand for the Swedish model. But we should not continue to challenge the regulations and risk getting judgments that lead nowhere in the application of the regulations,” he said.
Vision ultimately canceled its planned blockade against Tesla on December 9. With Vision’s withdrawal, few obstacles remain for Tesla’s long-planned Kalmar site. A foreign electrical firm completed work this fall, and Tesla’s Careers page currently lists a full-time service manager position based there, signaling an imminent opening.

Tesla Semi program Director teases major improvements
Tesla Semi Program Director Dan Priestly teased the major improvements to the all-electric Class 8 truck on Thursday night, following the company’s decision to overhaul the design earlier this year.
Priestley said he drove the Semi on Thursday, and the improvements appear to be welcomed by one of the minds behind the project. “Our customers are going to love it,” he concluded.

The small detail does not seem like much, but it is coming from someone who has been involved in the development of the truck from A to Z. Priestley has been involved in the Semi program since November 2015 and has slowly worked his way through the ranks, and currently stands as the Director of the program.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
Tesla made some major changes to the Semi design as it announced at the 2025 Annual Shareholder Meeting that it changed the look and design to welcome improvements in efficiency.
Initially, Tesla adopted the blade-like light bar for the Semi, similar to the one that is present on the Model Y Premium and the Cybertruck.
Additionally, there are some slight aesthetic changes to help with efficiency, including a redesigned bumper with improved aero channels, a smaller wraparound windshield, and a smoother roofline for better aero performance.
All of these changes came as the company’s Semi Factory, which is located on Gigafactory Nevada’s property, was finishing up construction in preparation for initial production phases, as Tesla is planning to ramp up manufacturing next year. CEO Elon Musk has said the Semi has attracted “ridiculous demand.”
The Semi has already gathered many large companies that have signed up to buy units, including Frito-Lay and PepsiCo., which have been helping Tesla test the vehicle in a pilot program to test range, efficiency, and other important metrics that will be a major selling point.
Tesla will be the Semi’s first user, though, and the truck will help solve some of the company’s logistics needs in the coming years.
