Tesla updates Model S, X: 370-mi range, faster charging, adaptive suspension
Rumors that a Tesla Model S and Model X refresh was arriving this year have been partially confirmed, with the electric carmaker announcing Tuesday afternoon that its flagship vehicles have been updated to use a completely new and highly-efficient drivetrain design, along with a new adaptive suspension.
Model S Long Range will have an industry leading 370-mile range per single charge, while Model X will boast a 325-mile range per charge. Tesla notes that the range increase is due in large part to a new drive unit design that leverages an optimized permanent magnet motor, improved cooling, bearings, and new gear design to achieve greater than 93% efficiency. The end result is improved range from the same battery cells that are currently being used in the Model S and Model X 100 kWh pack.
By improving drivetrain efficiency, Tesla has been able to effectively increase range by more than 10%. By improving the flow of energy out of the battery and back in through regenerative braking, Tesla was also able to further improve acceleration in the Model S and Model X.
“In addition to adding range, power and torque increases significantly across all Model S and Model X variants, improving 0-60 mph times for our Long Range and Standard Range models,” notes Tesla in its blog post.
In addition, Model S and Model X is now capable of recharging at a 50% faster rate from the help of new updates, including the more efficient drivetrain design. Similar to Tesla Model 3’s ability to charge at 1,000 miles per hour from Supercharger V3 when at a 250 kW max power output, Model S and Model X will be able to achieve 200 kW. It’s important to note that Tesla’s flagship vehicles will be able to charge at a faster rate from the same battery pack, while Model 3 utilizes a newer generation 2170 cylindrical cell with higher energy density than the Model S and Model X.
All Model S and Model X will now come with an upgraded air suspension system that uses software intelligence to adapt to various driving and road conditions.
“Unlike other manufacturers, our suspension software is developed completely in-house, using a predictive model to anticipate how the damping will need to be adjusted based on the road, speed, and other vehicle and driver inputs,” says Tesla, adding “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.”
In line with Tesla’s ability to constantly add new features to a vehicle and improve its performance through over the air software updates, Tesla’s new Fully Adaptive Suspension will continuously improve over time as new software is rolled out.
For performance enthusiast who’s an existing Model S or Model X owner, Tesla will be offering the $20k Ludicrous Mode upgrade for free on the purchase of a new Performance Model S or Performance Model X.
Details of the latest Model S and Model X update, including the addition of a Standard Range variant can be found in Tesla’s blog post. We’ve included it in its entirety below.
The Longest-Range Electric Vehicle Now Goes Even Farther
For more than a decade, Tesla engineers have been obsessed with making the world’s most efficient electric vehicles. As a result, Tesla vehicles already travel farther on a single charge than any other production EV on the market. Today, we’re making changes to Model S and Model X that allow them to travel unprecedented distances without needing to recharge, beating our own record for the longest-range production EVs on the road. And we’ve accomplished this without increasing the cars’ battery size, proving that our expertise in system-level design can make our cars dramatically more efficient.
Beginning today, Model S and Model X now come with an all-new drivetrain design that increases each vehicle’s range substantially, achieving a landmark 370 miles and 325 miles on the EPA cycle for Model S and Model X Long Range, respectively. Using the same 100 kWh battery pack, these design and architecture updates will allow drivers to travel farther than ever before, charging less frequently and getting more range out of every dollar spent on charging.
We’re also introducing a brand-new adaptive suspension system for Model S and Model X, along with a few other improvements for the best range, acceleration, and ride comfort ever, plus a Ludicrous Mode upgrade for our most loyal customers. Here’s what’s new:
More Efficient Design
All Model S and X vehicles now benefit from Tesla’s latest generation of drive unit technology, which combines an optimized permanent magnet synchronous reluctance motor, silicon carbide power electronics, and improved lubrication, cooling, bearings, and gear designs to achieve greater than 93% efficiency. Pairing a permanent magnet motor in the front with an induction motor in the rear enables unparalleled range and performance at all times. The net effect is a more than 10% improvement in range, with efficiency improvements in both directions as energy flows out of the battery during acceleration and back into the battery through regenerative braking. In addition to adding range, power and torque increases significantly across all Model S and Model X variants, improving 0-60 mph times for our Long Range and Standard Range models.
Faster Charging
Paired with the new more efficient drivetrain design, Model S and Model X are now capable of achieving 200 kW on V3 Superchargers and 145 kW on V2 Superchargers. Together, these improvements enable our customers to recharge their miles 50% faster.
Fully Adaptive Suspension
We’ve also upgraded our air suspension system for Model S and Model X with fully-adaptive damping, giving it an ultra-cushioned feel when cruising on the highway or using Autopilot, and a responsive, exhilarating confidence during dynamic driving. Unlike other manufacturers, our suspension software is developed completely in-house, using a predictive model to anticipate how the damping will need to be adjusted based on the road, speed, and other vehicle and driver inputs. 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. We’ve also improved the leveling of the system while cruising, keeping the car low to optimize aerodynamic drag. As with all of Tesla’s in-house software, the adaptive suspension can receive over-the-air updates, allowing us to enable all Model S and Model X customers to have the most advanced suspension technology at all times.
Constant Refinement
To complement these changes, we’ve also re-engineered several other components of Model S and Model X in keeping with our philosophy of continuous improvement. These updates include new wheel bearings and a few new tire designs for certain variants to improve range, ride, and steering. While these changes may seem minor, together they have a meaningful impact when it comes to EV design.
In addition to our Long Range and Performance variants, we’re also re-introducing a lower entry price for Model S and Model X by bringing back our Standard Range option, now available for an even greater value with the new drivetrain and suspension updates. We also want to emphasize the critical impact each of our early Tesla owners has had on advancing our mission, so as a thank you, all existing Model S and Model X owners who wish to purchase a new Model S or Model X Performance car will get the Ludicrous Mode upgrade, a $20,000 value, at no additional charge.
These changes will go into production at our factory in Fremont, California this week, and can be ordered today at Tesla.com.
Tesla’s Head of AI, Ashok Elluswamy, says that something that was expected with version 14.3 of the company’s Full Self-Driving platform has already partially shipped with the current build of version 14.2.
Tesla and CEO Elon Musk have teased on several occasions that reasoning will be a big piece of future Full Self-Driving builds, helping bring forth the “sentient” narrative that the company has pushed for these more advanced FSD versions.
Back in October on the Q3 Earnings Call, Musk said:
“With reasoning, it’s literally going to think about which parking spot to pick. It’ll drop you off at the entrance of the store, then go find a parking spot. It’s going to spot empty spots much better than a human. It’s going to use reasoning to solve things.”
Musk said in the same month:
“By v14.3, your car will feel like it is sentient.”
Amazingly, Tesla Full Self-Driving v14.2.2.2, which is the most recent iteration released, is very close to this sentient feeling. However, there are more things that need to be improved, and logic appears to be in the future plans to help with decision-making in general, alongside other refinements and features.
On Thursday evening, Elluswamy revealed that some of the reasoning features have already been rolled out, confirming that it has been added to navigation route changes during construction, as well as with parking options.
He added that “more and more reasoning will ship in Q1.”

More uses of reasoning will be shipped later this quarter, a big tidbit of info as we wait v14.3 https://t.co/jty8llgsKM

Interestingly, parking improvements were hinted at being added in the initial rollout of v14.2 several months ago. These had not rolled out to vehicles quite yet, as they were listed under the future improvements portion of the release notes, but it appears things have already started to make their way to cars in a limited fashion.
Tesla Full Self-Driving v14.2 – Full Review, the Good and the Bad
As reasoning is more involved in more of the Full Self-Driving suite, it is likely we will see cars make better decisions in terms of routing and navigation, which is a big complaint of many owners (including me).
Additionally, the operation as a whole should be smoother and more comfortable to owners, which is hard to believe considering how good it is already. Nevertheless, there are absolutely improvements that need to be made before Tesla can introduce completely unsupervised FSD.

Tesla’s Elon Musk: 10 billion miles needed for safe Unsupervised FSD
As per the CEO, roughly 10 billion miles of training data are required due to reality’s “super long tail of complexity.”
Tesla CEO Elon Musk has provided an updated estimate for the training data needed to achieve truly safe unsupervised Full Self-Driving (FSD).
As per the CEO, roughly 10 billion miles of training data are required due to reality’s “super long tail of complexity.”
10 billion miles of training data
Musk comment came as a reply to Apple and Rivian alum Paul Beisel, who posted an analysis on X about the gap between tech demonstrations and real-world products. In his post, Beisel highlighted Tesla’s data-driven lead in autonomy, and he also argued that it would not be easy for rivals to become a legitimate competitor to FSD quickly.
“The notion that someone can ‘catch up’ to this problem primarily through simulation and limited on-road exposure strikes me as deeply naive. This is not a demo problem. It is a scale, data, and iteration problem— and Tesla is already far, far down that road while others are just getting started,” Beisel wrote.
Musk responded to Beisel’s post, stating that “Roughly 10 billion miles of training data is needed to achieve safe unsupervised self-driving. Reality has a super long tail of complexity.” This is quite interesting considering that in his Master Plan Part Deux, Elon Musk estimated that worldwide regulatory approval for autonomous driving would require around 6 billion miles.
FSD’s total training miles
As 2025 came to a close, Tesla community members observed that FSD was already nearing 7 billion miles driven, with over 2.5 billion miles being from inner city roads. The 7-billion-mile mark was passed just a few days later. This suggests that Tesla is likely the company today with the most training data for its autonomous driving program.
The difficulties of achieving autonomy were referenced by Elon Musk recently, when he commented on Nvidia’s Alpamayo program. As per Musk, “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.” These sentiments were echoed by Tesla VP for AI software Ashok Elluswamy, who also noted on X that “the long tail is sooo long, that most people can’t grasp it.”

MotorTrend’s SDV Awards were presented during CES 2026 in Las Vegas.
Tesla emerged as one of the most recognized automakers at MotorTrend’s 2026 Software-Defined Vehicle (SDV) Innovator Awards.
As could be seen in a press release from the publication, two key Tesla employees were honored for their work on AI, autonomy, and vehicle software. MotorTrend’s SDV Awards were presented during CES 2026 in Las Vegas.
Tesla leaders and engineers recognized
The fourth annual SDV Innovator Awards celebrate pioneers and experts who are pushing the automotive industry deeper into software-driven development. Among the most notable honorees for this year was Ashok Elluswamy, Tesla’s Vice President of AI Software, who received a Pioneer Award for his role in advancing artificial intelligence and autonomy across the company’s vehicle lineup.
Tesla also secured recognition in the Expert category, with Lawson Fulton, a staff Autopilot machine learning engineer, honored for his contributions to Tesla’s driver-assistance and autonomous systems.
Tesla’s software-first strategy
While automakers like General Motors, Ford, and Rivian also received recognition, Tesla’s multiple awards stood out given the company’s outsized role in popularizing software-defined vehicles over the past decade. From frequent OTA updates to its data-driven approach to autonomy, Tesla has consistently treated vehicles as evolving software platforms rather than static products.
This has made Tesla’s vehicles very unique in their respective sectors, as they are arguably the only cars that objectively get better over time. This is especially true for vehicles that are loaded with the company’s Full Self-Driving system, which are getting progressively more intelligent and autonomous over time. The majority of Tesla’s updates to its vehicles are free as well, which is very much appreciated by customers worldwide.
