Tesla’s electric cars are known for being extremely quick, and they are also known for being extremely safe. The Model 3, the company’s most affordable car to date, for example, has aced safety ratings across the globe, earning a 5-Star rating from the NHTSA in the US, the Euro NCAP in Europe, and the ANCAP in Australia. Even the IIHS gave the Tesla Model 3 its highest rating, Top Safety Pick+

But this is Tesla, and the electric car maker is known for being a company that refuses to stay still. Its cars are already quick enough to give passengers serious Gs while launching, yet the company remains hard at work on making them even quicker and more visceral in terms of speed (e.g. the Model S Plaid Powertrain). In the same light, while Teslas are already safe at their current state, it is no surprise that the company remains dedicated to finding ways to make its vehicles even safer, both for passengers in the cabin and for pedestrians on the road.

One such example of this was highlighted in a recently published patent that was simply titled “Hinge Assembly for a Vehicle Hood.” Based on the electric car maker’s discussion, the novel hinge assembly has the potential to protect pedestrians who happen to hit the vehicle’s hood during a collision. Similar systems are in place in vehicles today, though Tesla maintained that conventional designs have lots of areas for improvement.

“Modern vehicles are mandated by safety standards to protect pedestrians from head-impact injuries, including a scenario in which a pedestrian would contact the vehicle’s hood. To meet these requirements. Current state of the art safety systems are active systems that typically include a sensor system to detect a collision with pedestrian and fire (using a pyrotechnic) an actuator to lift the front hood into a protective position before pedestrian impact. However, such systems may be falsely triggered and can only be used once because the pyrotechnic is not reversible. The pyrotechnic is also expensive, adding to overall cost of the vehicle. Therefore, there is a need for a safety system that overcomes the aforementioned drawbacks.”

Tesla noted in its patent’s description that its hinge assembly includes a body member and a hood member, with the latter being “pivotally coupled with a body member through a pivot pin.” In the event of a collision, a portion of the vehicle’s hood member or body member “deforms such that the hood member or body member disengages from the pivot pin.” This allows Tesla to use the hinge as a passive pedestrian safety system that does not require any additional components such as sensors or controllers. The design outlined in Tesla’s patent is also more practical than the pyrotechnic system used in conventional pedestrian impact safety systems. 

Tesla describes how its hood hinge works in a collision in the following section.

“FIG. 6 illustrates impact of a headform 602 on hinge assembly 116. Headform 602 represents the head (or portion thereof) of a pedestrian or other living being. As illustrated, when a collision occurs such that headform 602 hits a portion of hood member 108 of vehicle 100 along direction of an axis X-X′, a force is generated. When the force is great enough, the impact force causes hood member 108 to disengage from hinge assembly 116. The impact force typically causes deformation of portion 314 of hood member 108 adjacent to notch 312 such that pivot pin 202 disengages with second opening 304 of hood member 108. In embodiments, the width W of notch 312 is altered to change the impact force at which the hood member 108 disengages from hood member 108. In embodiments the impact force causes deformation of the pivot pin 202 to allow disengagement of hood member 108 from body member 110.

“In an event of collision, hood member 108 may disengage with hinge assembly 116 such that safety standards can be met. Hood member 108 may move down due to impact force and disengagement with hinge assembly 116. To allow movement of hood member 108, sufficient space may be provided by trimming away portions of hood member 108 and body member 110. Advantageously, this would lower weight of components while maintaining the safety standards for vehicle 100.”

Tesla is a carmaker that will likely never stay still. Despite its significant lead in the electric car segment thanks to its vehicles’ batteries and powertrain, Tesla is in a continuous process of improvement. The hood hinge outlined in this patent might be quite simple, but it contributes to the overall safety of Tesla’s lineup of vehicles nonetheless. Such initiatives, if any, further prove that when it comes to safety, no part is too small for innovation — and in the event of a collision, it’s these factors that can make all the difference.

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

Published

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.
