Tesla has launched FSD V12.5.5 with update 2024.32.20, which has just hit early access testers. This update includes several new things, including the new end-to-end highway stack and bringing FSD to the Cybertruck for the first time. Tesla also outlined additional features to expect in future revisions of FSD.
The End-to-End part of the stack means that rather than hand-coding all the decision-making directly into FSD, Tesla now relies upon AI, trained upon hundreds of thousands of hours of footage gathered by its fleet, to make decisions.
This is key to rapid improvements and will help to bring Unsupervised FSD – and Robotaxi – to realization. We’re especially excited to see these improvements with the Robotaxi event just around the corner.
End-to-End Highway Stack
FSD V12 brought the End-to-End stack to City Streets, and the Highway Stack was still running FSD V11. With this update, end-to-end AI will now be used on the highway, which should be a considerable improvement.
When End-to-End was introduced on city streets, it brought some drastic improvements in how FSD was handled between V11.4.9 and V12.3.6. There’s likely going to be a similar level of improvement between FSD V12.5.4 on the highway and FSD V12.5.5 on the highway.
As of today, FSD still tends to sit in the left lane, Auto-Speed doesn’t function on the highway, and the speed limit can change drastically where it's incorrectly mapped.
With the end-to-end highway stack, we could see FSD correctly use the left lane to overtake vehicles and then come back into the middle or right lane, as required. In addition, we could see Tesla add Auto-Speed functionality for the highway so that the vehicle is able to more fluidly respond to changes in traffic and speed more naturally.
Upcoming Improvements
In the release notes for FSD 12.5.5, Tesla also updated the list of features coming in future FSD versions, some of which Tesla hadn’t previously discussed or mentioned in the FSD Roadmap. In Tesla’s release notes, they specifically mention these upcoming improvements:
Earlier and more natural lane change decisions
Improved performanec in parking lots
Improved performance at intersections and stops
Introduction of Speed Profile
Earlier and More Natural Lane Changes
First off, Tesla mentions earlier and more natural lane change decisions. We’ve seen this one pop up before, and it's definitely a pain point for Tesla. Even today on FSD V12.5.4, FSD will still sometimes make lane change decisions within less than 200 feet of a turn, moving you from the far right to the left turning lane in a short space.
Addressing this will greatly help how smooth FSD will feel.
Improved Performance in Parking Lots
Tesla also mentions improved parking lot performance as coming soon. This particular enhancement to FSD will likely help improve Actually Smart Summon so that it can expand beyond FSD-specific updates and become available to more users. This will allow users with Enhanced Autopilot and owners outside of North America to gain access to Actually Smart Summon for the first time. Currently, Actually Smart Summon is available to users in North America with 2024.27.25.
In addition, we’re expecting Banish – also known as Reverse Summon – to rely upon these improvements. Banish will allow your vehicle to drop you off at an entrance to a location, and then find a parking stall, and park itself. This is going to be another key item for Robotaxi and Unsupervised FSD and is one of the items we’re the most excited about.
Improved Performance at Intersections and Stops
FSD V12.5 brought along some oddities regarding intersections. Owners have been reporting FSD stopping for green lights or double braking on stop signs. This feature is likely to target some of these existing issues.
While FSD V12.5 also brought pretty drastic improvements for roundabouts, there are still some issues with signalling and lane selection in multi-lane roundabouts, so maybe they’ll address those here as well. This is a pretty broad category, so we can only imagine what they’ll be doing here.
Introduction of Speed Profile
We previously reported that Elon Musk wanted to add a new FSD drive mode. It appears that FSD’s Assertive Mode will become “Hurry Mode.” However, based on the release notes, Tesla seems to imply that it may not be called Hurry Mode but instead Speed Mode. This mode will likely be an option that tells FSD to go a bit faster and also become more aggressive with overtaking – something that has become more common and much smoother with FSD V12.5. This is going to be an interesting addition or change, and we’ll be sure to dig into it more in the future when it becomes available.
Release Date
Tesla’s Autopilot director Ashok Elluswamy posted on X that while the Cybertruck is receiving FSD 12.5.5 with the end-to-end highway stack, don’t expect it to roll out to other vehicles immediately. Tesla prioritized getting this out for the Cybertruck and they’re still working on getting the highway stack ready for other vehicles. Ashok said that he expects Tesla to have an internal build ready in about a week or so. With Tesla’s robotaxi event just 10 days out, it sounds like this won’t arrive on customer vehicles until after the event.
Great job by the @Tesla_AI team on meeting the goals laid out for September🤩
End-to-end on the highway is first shipping to Cybertrucks. We are close to an early release build for remaining platforms and will release to internal employees in the next week or so.
Tesla’s marketing has always been relatively unconventional, relying on word-of-mouth rather than traditional advertising. The passion of the owner’s community is always massive, but it is especially high now with the launch of the Robotaxi network just around the corner.
Tesla is now tapping into that spring of fan creativity and announced the TeslaVision video contest, with some seriously impressive prizes up for grabs.
Announcing the TeslaVision fan video showcase
Tesla owners & supporters have always been able to see our products & mission for what they truly are.
Your word of mouth has made Tesla what it is today.
The OGs will remember that in 2017, we held our first video contest. 8 years… pic.twitter.com/6pPpkqmqOH
The core of the contest is simple. Create a video that shows how your Tesla gives you more in life. Tesla is looking for submissions that highlight themes of freedom, safety, fun, and convenience.
Prizes
The prizes definitely make this contest worth entering if you’re good with a camera and have some basic video editing abilities.
For North America, the prizes include a brand new Model Y AWD Long Range, alongside an all-expenses-paid trip to Austin for a tour of Giga Texas. The grand prize winner will also be able to custom order their Model Y, allowing them to select their preferred wheels and color.
The two runners-up won’t get a Model Y, but they’ll also enjoy an all-expenses-paid trip to Giga Texas for a tour of the factory.
The travel and tour include lodging in Austin for 2 nights, as well as economy-class round-trip tickets from anywhere in North America. Tesla will also provide a vehicle for use during the trip.
For long-time followers of Tesla, this contest may feel familiar. The contest is a direct throwback to the 2017 Project Loveday contest, which was inspired by a letter to Tesla from a 10-year-old aspiring marketer. That contest was won by MKBHD, with his submission below:

After numerous sightings and weeks of anticipation, Tesla has finally unveiled the refreshed Model S and Model X. While we knew what to expect, Tesla managed to sneak in a few additional improvements, such as increasing the range for these vehicles.
While not a ground-up redesign, this update introduces a front bumper camera, ambient lighting, new wheels, colors, and more.
Let’s go through all the changes.
Longer Range
Tesla is increasing the range of these vehicles, with the Model X seeing the biggest improvements. These changes are likely the result of improved aerodynamic efficiency from the new wheel designs and other smaller improvements.
The biggest gain comes from the Model X Long Range, which increases its range from 329 miles to 352 miles, an improvement of 23 miles or about 7%.
Below is a table with the new and old ranges for these vehicles.
2025 Model

410 mi
Model S Plaid
348 mi
368 mi
Model X Long Range

352 mi
Model X Plaid
314 mi
335 mi
New Bumpers
The most noticeable exterior change is reserved for the Model S and X Plaid, which are both receiving an updated front fascia with a new, sportier bumper. While the change looks subtle, the new lower spoiler lip gives both vehicles a slightly more aggressive look while also improving aerodynamics, according to Tesla.
New Grill
The new Model S
Not a Tesla App
Tesla has also updated the grill on these vehicles slightly. The Long Range model now has the entire grill area, including the Tesla logo in matte black instead of chrome. The Plaid versions receive a carbon fiber accent in the grill, which helps the Plaid models stand out.
Front Bumper Camera
Same Headlights, but still slick in the new Frost Blue.
Not a Tesla App
Putting the stylistic changes aside, embedded in that front bumper is a new front-facing bumper camera with this refresh. This finally brings the Model S and Model X on par with the Cybertruck and refreshed Model Y - and leaves the refreshed Model 3 as the last of Tesla’s vehicles without a bumper camera.
Tesla is introducing four new sets of wheels with new specifications for these updated models. The Perihelix wheels are standard on the Model X and the Magnetite wheels are standard on the Model S. Velarium wheels are a $4.5k premium for the Model S, while the Machina wheels on the X cost an additional $5,500.
However, as you can see in the table below, the optional wheels also reduce the range of these vehicles.

*The Plaid’s 200mph top speed requires the updated Track Pack, which is currently not available.
New Colors
Not a Tesla App
Joining the color palette for this refresh are two new colors. Frost Blue Metallic is a new light blue multi-coat paint option. Tesla is also introducing Diamond Black for both its flagship vehicles. The previous colors, Stealth Grey (Standard), Pearl White Multi-Coat, Ultra Red, and Lunar Silver, remain available as well.
Frost Blue will be a premium paint option for $2,500 USD, while Diamond Black will cost $1,500 USD.
New Animated Ambient Lighting
The updated interior.
Not a Tesla App
Inside, the refresh introduces a feature that has become a standard for the rest of Tesla’s lineup: multi-color ambient lighting. The configurable light strip wraps around the cabin, similar to the rest of Tesla’s vehicles, and offers owners some additional personalization. The light strip extends from the dashboard to both sides of the center console and through the front and rear doors.
Unlike the Model 3 and Model Y, the ambient lighting isn’t just on the dash and doors. Tesla also added it to the sides of the center console, which helps differentiate it slightly from the Model 3 and Y while also illuminating the cabin a little more.
Even more so, this ambient lighting can now be animated, allowing lights to transition to different colors so that the entire strip doesn’t need to be the same color.
A lot has been worked on. The outer changes kinda hide the changes underneath. The team looked at the Palladium Cars and worked though a ton of small improvements. Thermals, NVH, Chassis,... everything.
All of these improvements across the car lead to a greater efficiency,…
The LED footwell lights and door pocket lights are now also color-selectable, which is a new feature that’s exclusive to the Model S and X. The footwell and pocket lights can be controlled independently or synced to the light strip lighting. While these little touches are a nice addition, they don’t do much to set these vehicles apart from the Model 3 and Y.
New Startup Animation
The new startup animation for the updated Model S and X.
This animation is tied to the new animated ambient lighting, which allows the lights to transition to other colors instead of being all one color.
Tesla has also added a new entry animation that plays when the driver or front passenger doors are opened, which is synced across the dash and door trim lighting. This is similar to the new Model Y Launch Series animation, but Tesla takes it to a new level here by incorporating the ambient lighting.
The animation begins on the center display, zooming out on a red-glowing Tesla logo. The red light then spreads to the instrument cluster and is then carried throughout the cabin via the ambient lighting. It’s a nice touch.
Improved Noise Isolation
The Model S and Model X have always been quiet compared to the Model 3 and Model Y, but Tesla says they’ve made it even quieter in this refresh. They reduced wind and road noise and improved their Active Noise Cancellation feature.
While it’s unclear how much quieter they are, these new vehicles are heavier than the version they replaced, so additional sound-dampening material was likely added.
Improved Suspension
In Tesla’s post on X, they say these models also have a smoother ride thanks to new bushings and an updated suspension design. Although Tesla likely didn’t update these vehicles to use the newer suspension in the Cybertruck, it’s good to know there are some improvements here as well.
Improved Third Row and Cargo Space
The Model X also gets a boost in practicality, with some additional room in the third row. Before anyone gets too excited about this, it’s important to understand that the frame of the vehicle hasn’t changed, so the improvements here are likely minor.
When we compare the cargo room information provided by Tesla for the previous vehicle to this new one, the total cargo space increases from 92 cubic feet to 94.5 cubic feet, representing a 2.5 cubic foot improvement. Although this appears significant, it’s unclear where the changes are coming from.
It’s possible they redesigned the bottom trunk area to expose more room that was available underneath the cabin, or they may have improved the third-row seats to expose the area underneath them, but unfortunately, we just don’t have enough information to know for sure.
Yoke Steering Wheel
While there are no changes to the steering wheel in these vehicles, Tesla is now making the optional yoke steering wheel only available on the Plaid models.
These vehicles initially launched with the yoke steering wheel, but Tesla later added an option to choose between the yoke or standard steering wheel option. Soon after, Tesla made the yoke steering wheel a $1,000 option and the standard wheel became the default option. Now, the yoke steering wheel is only available as an optional upgrade for the Model S and Model X Plaid variants.
Same FSD and MCU Hardware
While the interior and exterior have received some light touch-ups, the actual hardware that powers the infotainment unit and FSD has not been upgraded.
While Tesla is already working on HW5, it’s not due out until sometime next year. These vehicles, just like the Model 3 and Y, will include FSD HW4 and the AMD Ryzen (MCU3) powered infotainment unit.
Price Increase
Tesla has updated the pricing on both the Model S and Model X, increasing the price by $5k across the various trim levels.
The absence of these features and the price increase leave some wondering whether these vehicles may be worth the price, especially since so many features were brought over to the new Model 3 and Model Y.
Given that the changes to the design are relatively minimal, Tesla likely has only a few minor tooling updates to make. Over on the website, new orders have an estimated delivery window of approximately 3 to 5 weeks.
Tesla will likely begin reaching out to customers who’ve previously ordered a new Model S or Model X and note that the vehicle they receive will be the refreshed variant instead. Those customers previously had a 2-4 week wait before their orders were ready.
It seems likely that over the next few weeks, Model S and Model X inventory vehicles will begin to receive some light discounts to get any leftover vehicles moving. In general, Tesla keeps a relatively low inventory of its two flagships, so if you spot an older S or X and are in the market for a discount, this will likely be your chance.
