Tesla Model S owner reminds us of ‘Active Hood’ pedestrian safety feature

Published

on

A relatively unknown Tesla safety feature called ‘Active Hood’, designed to reduce head injuries to pedestrians in the event of a frontal collision, was brought to light in a recent Model S owner’s video that attempts to capture Tesla’s Automatic Emergency Braking (AEB) in action. Active Hood which exists on European and Australian Model S vehicles uses pyrotechnics to raise the rear of the hood by several inches in order to soften the impact of a pedestrian and cyclist against a windshield during frontal impact.

Model S owner and Tesla Motors Club forum member Carspotter Daily posted a video that attempts to simulate a vehicle-pedestrian interaction. The vehicle was a first generation Autopilot vehicle under Firmware 8.0. It’s unclear whether CarSpotter was intentionally trying to trigger Tesla’s Active Hood feature or whether they were looking to test the AEB system, but despite not being able to trigger either feature the end result revealed, once again, Autopilot’s ability to detect humans. Another Tesla owner YouTuber KmanAuto first detected the pedestrian alert last November when he put a friend in front of of his moving Model S.

This type of granular detection of objects allows the vehicle to respond to potential collisions in the most appropriate way, with the objective to reduce collisions entirely. Though Active Hood was mentioned in the trailing notes at the end of the recent video, it’s not clear if the vehicle used in the video is a U.S. spec Model S or a European/Australian version that was included with that safety feature.

Active Hood is not a new feature but the fact that it has only been implemented on Tesla vehicles in select markets that mandate the technology has kept it largely under the radar. The technology was built into Tesla vehicles to comply with Euro NCAP Pedestrian Safety requirements that mandate vehicle manufacturers to maintain clearances between the hood and structural components underneath, to protect pedestrians in the event of a low to medium speed collision. These accidents often prove fatal to the pedestrian, as collisions at low to medium speeds typically cause the pedestrian’s body to fold over the hood with the head hitting the windshield.

The system was put to use in real world conditions in Australia in 2015 when someone driving a Tesla Model S collided with a kangaroo which caused the system to deploy. From what they saw after the accident, it looked like the adolescent ‘roo had a broken leg but was conscious enough after the accident to limp away which seems to indicate that it was successful in preventing immediate head trauma.

Tesla had a special challenge when designing Active Hood since the front trunk of a Model S is sealed to keep water out whereas hoods to internal combustion engine vehicles  are generally vented. US Patent Application US20130076076 A1 details the specific challenges and solutions developed to allow the hood to pop up in response to an imminent collision with a pedestrian.

The English European version of the Tesla Model S manual lays out the technology in a much more user friendly format:

Active Hood

Model S features a pyrotechnically-assisted pedestrian protection system that reduces head injuries to pedestrians and cyclists in a frontal collision. If the sensors in the front bumper detect an impact with a pedestrian when Model S is moving between 19 and 53 km/h, the rear portion of the hood automatically raises approximately 80 mm. This creates space between the relatively soft hood and the hard components beneath to absorb some of the impact energy in a collision.
Note: The pedestrian protection system relies on a series of sensors and algorithms to determine when Active Hood should deploy. Therefore, the system may not deploy in all collision or crash situations.

If Active Hood has been deployed, the instrument panel displays an alert and an audible chime sounds. Immediately take Model S to the nearest Tesla Service Center. Active Hood’s associated sensors and actuators must be serviced by Tesla whenever Active Hood has been deployed.
Warning: Deployment of Active Hood may cause the raised hood to partially obstruct driver vision. Driving a car with a deployed hood increases the risk of a collision. A car with a deployed hood should be immediately taken to the nearest Tesla Service Center.
Warning: If the instrument panel displays an alert indicating that Active Hood has been deployed in situations where it has not, immediately drive Model S to the nearest Tesla Service Center.
Note: If damage occurs to the front bumper, contact Tesla for a list of Tesla-approved body shops in your area. Tesla approves specific body shops to ensure they meet strict requirements for training, equipment, quality, and customer satisfaction.

With Active Hood technology only existing on vehicles destined for the European and Australian markets, and Tesla being so aggressive about implementing safety features, the natural question is “why hasn’t Tesla made this a standard global safety feature?” An early Euro NCAP crash test video showed that Tesla began working hard at doing everything it can to avoid the accident in the first place. After all, avoiding a collision in the first place is far better for all parties involved than just mitigating what happens afterwards.

Tesla hints at Starlink integration with recent patent

“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”

Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.

The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”

Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.

These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.

They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:

“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”

One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.

It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).

Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.

Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.

It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.

Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.

Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version

It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.

Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.

Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.

For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.

It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.

Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.

As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.

This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:

  • Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
  • Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
  • Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
  • Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
  • Santa Mode – New graphics, trees, and a lock chime
  • Light Show Update – Addition of Jingle Rush light show
  • Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
  • Navigation Improvements – Easier layout and setup
  • Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
  • Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
  • Phone Left Behind Chime – Your car will now tell you if you left a phone inside
  • Charge Limit Per Location – Set a charge limit for each location
  • ISS Docking Simulator –  New game
  • Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition

Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.

Tesla updates Cybertruck owners about key Powershare feature

Published

Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.

Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.

Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.

However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.

Powerwall discharge would be prioritized before tapping into the truck’s larger pack.

However, Tesla is still working on getting the feature out to owners, an email said:

“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026. 

This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”

Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.

Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.

Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”

It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
