Tesla’s Full Self-Driving (FSD) software and recent Model S and Model X updates may usher in a new era for responsive vehicle suspension systems. The key lies within the FSD’s ability to predict driving paths.

Improved versions of Tesla’s flagship vehicles were recently announced as under production by the all-electric car maker, and listed among the battery and performance improvements was the heading ‘Fully Adaptive Suspension’, which adjusts dampening based on driving conditions. “The system constantly adapts by sensing the road and adjusting for driver behavior, automatically softening for more pronounced road inputs and firming for aggressive driving,” Tesla wrote.

The current version of Tesla vehicles’ air suspension allows drivers to set a height preference based on GPS location; however, direct user input is required to create the settings. As described, Fully Adaptive Suspension indicates that the car’s software will make those choices instead based on calculations using road conditions. A neural network trained to determine those road conditions ahead of time and then preemptively adapt the suspension without input would be a perfect matchup for the technologies.

This predictive ability also happens to be something Tesla’s FSD computer is trained to do at length, if only primarily for self-driving direction rather than self-determining driver comfort settings.

The improved suspension announcement came on the heels of Tesla’s Autonomy Day, a live streamed event which gave viewers and investors a deep dive into the inner workings of the self-driving software being developed. During the presentation, how Tesla’s FSD computer determines which driving actions to take was discussed in depth as were the results of its determinations.

“The network is predicting paths it can’t even see with incredibly high accuracy,” CEO Elon Musk emphasized during the presentation. “If [the FSD computer] had never seen [a] road before, it would still have made [accurate] predictions provided it was a road in the United States.”

Just like its FSD computer, Tesla’s suspension software is developed in-house to cater to its vehicles specific needs and keep customers updated with the most advanced suspension technology available at all times.

Tesla additionally added aerodynamically-focused settings to further streamline its Model S and Model X speed and battery performance. “We’ve also improved the leveling of the system while cruising, keeping the car low to optimize aerodynamic drag,” the company announcement detailed, referring to another feature of its Fully Adaptive Suspension. Better aerodynamics results in less wind resistance, translating to less energy (battery power) being used when pushing the car through the air.

Altogether, an autonomously preloaded suspension system using predicted road conditions would be a potential boon for both driver enjoyment and battery efficiency.

Tesla takes first step in sunsetting Model S and X with drastic move

Tesla won’t be taking custom orders of the Model S or Model X in Europe any longer.

Tesla has seemingly taken the first step in sunsetting two of its older vehicles, the Model S and Model X, by ending international orders.

The flagship sedan and SUV from Tesla are the two oldest cars in the company’s lineup. They account for a very small portion of overall sales, and several years ago, CEO Elon Musk admitted that Tesla only continues to build and sell them due to “sentimental reasons.”

Earlier this year, there were calls for Tesla to end the production of the two cars, but Lars Moravy said that the Model S and Model X were due to get some love later in 2025. That happened, but the changes were extremely minor.

Tesla launches new Model S and Model X, and the changes are slim

Some took this as an indication that Tesla has kind of moved on from the Model S and Model X. A handful of people seemed to think Tesla would overhaul the vehicles substantially, but the changes were extremely minor and included only a few real adjustments.

In Europe, customers are unable to even put a new order in on a Model S or Model X.

We noticed earlier today that Tesla pressing the ‘Order’ button on either of the flagship vehicles takes you to local inventory, and not the Design Studio where you’d configure your custom build:

Tesla simply does not make enough Model S or Model X units to justify the expensive logistics process of shipping custom orders overseas. It almost seems as if they’re that they will essentially build a bunch of random configurations, send them overseas every few months, and let them sell before replenishing inventory.

Inversely, it could also mean Tesla is truly gearing up to sunset the vehicle altogether. It seems unlikely that the company will fade them out altogether in the next couple of years, but it could absolutely think about ending international orders because volume is so low.

Tesla confirms massive hardware change for autonomy improvement

Tesla has confirmed that a recent change made to some of its recently refreshed vehicles is, in fact, a strategy it will use to improve its suite as it continues to work toward autonomy.

Tesla has confirmed that a recent change made to some of its recently refreshed vehicles is, in fact, a strategy it will use to improve its suite as it continues to work toward autonomy.

Tesla first introduced a front-facing camera on the front bumper with the Cybertruck.

Then, the Model Y “Juniper” received the hardware update. The Model S and Model X both received the front-facing camera with its latest update, which was officially revealed last week.

Tesla used new language with the release of the front-facing cameras on the Model S and Model X, confirming they will assist with several things, including “using Autopilot and Actually Smart Summon capabilities”:

“Enhanced visibility when parking or using Autopilot and Actually Smart Summon capabilities.”

This tiny feature on the new Tesla Model Y is perhaps its biggest addition

This is the first time Tesla has used this sort of language, as it was a completely different description with the launch of the new Model Y in January.

When Tesla launched this vehicle, it said the front bumper camera “provides a wider field of view for automatic assisted driving and advanced Smart Summon.”

Tesla switched from using cameras and sensors to only cameras with the launch of Tesla Vision several years ago. The company’s utilization of cameras comes from Tesla’s belief that Ultrasonic Sensors (USS) are not needed for self-driving efforts:

“Along with the removal of USS, we simultaneously launched our vision-based occupancy network – currently used in Full Self-Driving (FSD) (Supervised) – to replace the inputs generated by USS. With today’s software, this approach gives Autopilot high-definition spatial positioning, longer range visibility and the ability to identify and differentiate between objects. As with many Tesla features, our occupancy network will continue to improve rapidly over time.”

CEO Elon Musk has said that sensors were only a crutch and that self-driving would be solved through the use of cameras:

“When your vision works, it works better than the best human because it’s like having eight cameras, it’s like having eyes in the back of your head, beside your head, and has three eyes of different focal distances looking forward. This is — and processing it at a speed that is superhuman. There’s no question in my mind that with a pure vision solution, we can make a car that is dramatically safer than the average person.”

Tesla launches new Model S and Model X, and the changes are slim

Tesla’s newest versions of its flagship vehicles have arrived with some slim changes.

Tesla has officially launched the newest versions of its flagship Model S and Model X vehicles, but the changes are pretty slim, which is something we expected when a couple cars were spotted during public testing recently.

The new “refreshed” Model S and Model X were spotted recently by The Kilowatts, and the changes appeared to be a new front camera, a new color, and only a handful of other changes.

Tesla officially announced the launch of the Model S and Model X on Thursday night, and here’s what it listed as the changes to the two vehicles:

  • Frost Blue paint color
  • Up to 410 miles of range (Model S Long Range – our longest range Tesla yet)
  • Even quieter inside: less wind + road noise & more effective Active Noise Cancellation
  • New wheel designs & improved aerodynamics = more range
  • Front fascia camera for better visibility
  • Dynamic ambient lighting that brings unique animations along the dash & doors upon entry
  • An even smoother ride thanks to new bushings & suspension design
  • Adaptive driving beams
  • New exterior styling for Model S Plaid, optimized for high-speed stability
  • More space for 3rd row occupants & cargo (Model X)

We expected most of these changes, especially the new Frost Blue paint color, as it was spotted by The Kilowatts in its initial coverage of the cars being spotted a few weeks back. Here’s what it looks like officially:

Some of the changes are familiar from the Model Y Refresh, which featured the quieter interior through acoustic-lined glass, a front fascia camera, new bushings, and suspension improvements for a smoother ride.

However, Tesla did refine the Model S Plaid’s exterior for “optimized high-speed stability.” You can see the difference between the two below:

The front-end air diffusers are much deeper, and the front end is more boxy than the previous iteration of the Plaid Model S.

Here are some more images of the Model S that Tesla released in a teaser video:

Tesla sells such a low volume of the Model S and Model X that it was probably less than likely that the company would put endless manpower and effort into completely redesigning it. CEO Elon Musk said a few years ago that the two cars would only stay in production for “sentimental reasons.”

While they are very special to the Tesla family, they are not incredibly important to the mission of the company.
