Tesla's most recent FSD Beta, v11.4.7.3 was released almost a month ago on October 19th, but it now looks like Tesla may be looking to release another FSD Beta update.

Release notes for an alleged subsequent version, FSD Beta 11.4.8, have surfaced on Reddit. While their authenticity isn't confirmed, the release notes use the same syntax and language Tesla typically uses. Here's a breakdown of what may be included in Tesla's next FSD release.

Update: These release notes have now been confirmed and the update is rolling out to Tesla employees for further testing. The update is version 2023.27.11.

Simplified Autopilot Activation

Single-Tap Autopilot: The update reportedly allows drivers to activate Autopilot with just one press of the stalk, instead of the current two-press method. This could make engaging and disengaging Autopilot quicker and more straightforward.

This feature, along with separate audio for passengers using the rear display recently made its way to production in update 2023.38.8, which adds some credibility to these leaked release notes. This could also mean that this version of FSD Beta may be based on a more recent production branch, instead of the current version of 2023.27, which is now starting to lag in terms of features.

Advanced Video Processing

New Video Module: A new video processing component has been introduced to improve vehicle detection, movement understanding (semantics), speed (velocity), and other attributes. This improvement means the system can process visual information more efficiently and quickly, enhancing overall performance.

Enhanced Object Detection

Better Object Detection: The system's ability to notice objects crossing its path is said to be improved by 6%. Additionally, vehicle detection has become more precise due to updated data and the new video module.

Improved Vehicle Interaction

Cut-In Vehicle Detection: The precision in detecting vehicles that cut into the Tesla's lane is reportedly improved by 15%. This is crucial for safer lane changes and merges.

Accuracy in Speed and Movement

Reduced Errors in Speed and Acceleration: The system now makes fewer errors in judging other vehicles' speed (by 3%) and acceleration (by 10%). This means a more accurate response in traffic.

Faster Decision-Making

Reduced Network Latency: The update claims to reduce the delay (latency) in the vehicle's decision-making network by 15%, allowing for quicker responses without compromising performance.

Pedestrian and Cyclist Safety

Rotation Error Reduction: There's an over 8% reduction in errors related to understanding how pedestrians and cyclists are moving or turning. This could improve interactions with these road users.

Enhanced Parking Assistance

Vision Park Assist Accuracy: The geometric accuracy of the Vision Park Assist system is improved by 16%, making parking assistance more reliable by leveraging data from hardware 4 vehicles. It appears that these improvements will apply to all vehicles without ultrasonic sensors, although it's not very clear.

Smoother Lane Changes

Lane Change Accuracy: The accuracy of lane changes in response to path blockages is improved by 10%, likely leading to smoother and safer driving in complex traffic situations.

While these updates, if true, indicate a continued effort by Tesla to refine and improve FSD Beta, Tesla also continues work on the next major release of FSD Beta, version 12. V12 is expected to be 'end-to-end' neural networks, which will be the first time that neural networks are used to control the vehicle.

It's not clear when Tesla expects to release FSD v12, which is also when Musk says FSD will graduate from its beta status. Musk recently showed off FSD v12 and its capabilities in a livestream on X.

The complete release notes that were shared on Reddit are below.

-Added option to activate Autopilot with a single stalk depression, instead of two, to help simplify activation and disengagement.

-Introduced a new efficient video module to the vehicle detection, semantics, velocity, and attributes networks that allowed for increased performance at lower latency.This was achieved by creating a multi-layered, hierarchical video module that caches intermediate computations to dramatically reduce the amount of compute that happens at any particular time.

-Improved distant crossing object detections by an additional 6%, and improved the precision of vehicle detection by refreshing old datasets with better autolabeling and introducing the new video module.

-Improved the precision of cut-in vehicle detection by 15%, with additional data and the changes to the video architecture that improve performance and latency.

-Reduced vehicle velocity error by 3%, and reduced vehicle acceleration error by 10%, by improving autolabeled datasets, introducing the new video module, and aligning model training and inference more closely.

-Reduced the latency of the vehicle semantics network by 15% with the new video module architecture, at no cost to performance.

-Reduced the error of pedestrian and bicycle rotation by over 8% by leveraging object kinematics more extensively when jointly optimizing pedestrian and bicycle tracks in autolabeled datasets.

-Improved geometric accuracy of Vision Park Assist predictions by 16%, by leveraging 10x more HW4 data, tripling resolution, and increasing overall stability of measurements.

-Improved path blockage lane change accuracy by 10% due to updates to static object detection networks.

Tesla's New Model S and Model X Spotted: New Color & Grill, Ambient Lighting and Front Bumper Camera

May 23, 2025

Tesla’s long-anticipated refresh of the Model S and Model X is drawing closer, and we’re finally getting a clearer look at what to expect. Although the update is relatively minor, it does help freshen up the look of the Model S and Model X since their redesign in 2021.

A camouflaged Model S was spotted at the Nürburgring just days ago, revealing new front and rear bumpers along with Tesla’s long-awaited addition: a front bumper camera.

New Grill

While the camouflage made the grill-like opening at the front of the vehicle hard to spot, it was evident something was there. However, new photos shared by The Kilowatts show that Tesla is covering up this opening with a material that has a carbon fiber finish, at least on the Plaid variant.

While we were hoping for more drastic changes, such as a grill-less look with a light bar, similar to the new Model Y, it looks like that won’t happen with this refresh.

The limited design changes suggest Tesla may be trying to limit tooling and manufacturing changes for these lower-volume vehicles. While the headlights already support adaptive beams, they remained unchanged from the current Model S and Model X.

Tesla has also updated the rear diffuser, though it’s unclear if this will be exclusive to the Plaid version. While the refreshed Model Y moved its rear camera up into the rear trim piece, the Model S keeps it in the same location as the previous generation.

Ambient Lighting Arrives

For the first time, we’re getting a look at the refreshed interior — and there’s one noticeable addition: ambient lighting. This feature, which is now available on all of Tesla’s other vehicles, is finally making its way to the Model S and Model X. The implementation appears closer in style to the Model Y, with lighting running along the door panels but stopping about halfway down before continuing on the rear doors.

While ambient lighting is primarily aesthetic, Tesla has been expanding its use for more dynamic and interactive features.

Recent Ambient Lighting Additions

Over the last year, Tesla has made the ambient lighting feature more useful by integrating it with other Tesla vehicles. For example, Santa Mode and Rainbow Road easter eggs will now take advantage of the ambient lighting, with Santa Mode cycling the colors between red and green for a Christmas flair [videos], while Rainbow Road cycles the colors of the rainbow.

Tesla has also added other little additions, such as turning the ambient lighting red when Service Mode is active in the vehicle. They have also added additional options in recent updates to ambient lighting, such as the ability to choose the brightness of the lights and choose whether they'll always remain on or only come on at night.

New Exterior Color

The refreshed Model X was also spotted in a new exterior color, similar but not identical to the Glacier Blue available on the new Model Y outside North America.

Launch Timeline

Although Tesla hasn’t officially said anything about a new Model S besides that, it’ll receive some “love” later this year. The Kilowatts noted that Tesla doesn’t have any Model S or X vehicles in their Fremont outbound lot, making it seem like these models could be announced any day now.

While the updates are relatively minor in terms of body redesign, the addition of the front bumper camera and ambient lighting are very welcome additions.

Stay tuned to see if there are any additional changes to these vehicles.

Tesla has begun selling a new Charcoal Suede dash insert for owners of the refreshed (2024+) Model 3 and refreshed (2026+) Model Y in the Tesla store.

Currently, both refreshed Model 3 and Model Y are shipping with a textile dash finish. This new accessory upgrades that surface to a vegan Alcantara suede, which is soft-to-the-touch and considerably more premium than the standard option.

For owners of the Launch Edition Model Y, this suede trim was included as part of the Launch Edition. Now, other refreshed Model Y owners can take advantage of the more premium Alcantara suede to achieve the same look and feel in their RWD or AWD vehicles.

Sweet, Smooth, Suede.

Pricing and Installation

Best USB drive for Tesla

View one of the highest rated USB drives for Tesla's dashcam in a Model 3 or Model Y.

For those looking to make the upgrade, the Charcoal Suede dash insert is priced at $250 USD / $345 CAD with installation included. Currently, availability is limited to the United States and Canada, but it will likely become available in Europe and Asia-Pacific over the coming weeks.

If you do purchase it, the dash insert will be sent to your service center, and you’ll be prompted to make a service appointment at that location. This is the same procedure as if you were getting a tow hitch installed on your Tesla by purchasing it through the Tesla app.

The pricing includes installation by the selected service center. Tesla has indicated that the installation process should take approximately 90 minutes for the Model Y and 120 minutes for the Model 3. It would have been nice to see self-installation included, which would help reduce the cost of the part.

Future Options

This type of dash trim upgrade is something we expected when the new Model 3 was launched in 2023. The redesigned dash makes it easier to swap out trim pieces, so it’s great to see Tesla finally offering different dash trims. We speculated that Tesla might eventually introduce different dash trims—either to match the vehicle’s exterior or to provide a more premium feel—and that’s exactly what this appears to be.

It’s a welcome addition that helps owners personalize their Teslas, especially given the limited customization options available at purchase. We hope Tesla continues expanding these choices.
