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 dispels reports of ‘sales suspension’ in California
“This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.
Sales in California will continue uninterrupted.”
Tesla has dispelled reports that it is facing a thirty-day sales suspension in California after the state’s Department of Motor Vehicles (DMV) issued a penalty to the company after a judge ruled it “misled consumers about its driver-assistance technology.”
On Tuesday, Bloomberg reported that the California DMV was planning to adopt the penalty but decided to put it on ice for ninety days, giving Tesla an opportunity to “come into compliance.”
Tesla enters interesting situation with Full Self-Driving in California
Tesla responded to the report on Tuesday evening, after it came out, stating that this was a “consumer protection” order that was brought up over its use of the term “Autopilot.”
The company said “not one single customer came forward to say there’s a problem,” yet a judge and the DMV determined it was, so they want to apply the penalty if Tesla doesn’t oblige.
However, Tesla said that its sales operations in California “will continue uninterrupted.”
It confirmed this in an X post on Tuesday night:

The report and the decision by the DMV and Judge involved sparked outrage from the Tesla community, who stated that it should do its best to get out of California.
One X post said California “didn’t deserve” what Tesla had done for it in terms of employment, engineering, and innovation.
Tesla has used Autopilot and Full Self-Driving for years, but it did add the term “(Supervised)” to the end of the FSD suite earlier this year, potentially aiming to protect itself from instances like this one.
This is the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” naming. Previous Transportation Secretary Pete Buttigieg was vocally critical of the use of the name “Full Self-Driving,” as well as “Autopilot.”

New EV tax credit rule could impact many EV buyers
We confirmed with a Tesla Sales Advisor that any current orders that have the $7,500 tax credit applied to them must be completed by December 31, meaning delivery must take place by that date. However, it is unclear at this point whether someone could still claim the credit when filing their tax returns for 2025 as long as the order reflects an order date before September 30.
Tesla owners could be impacted by a new EV tax credit rule, which seems to be a new hoop to jump through for those who benefited from the “extension,” which allowed orderers to take delivery after the loss of the $7,500 discount.
After the Trump Administration initiated the phase-out of the $7,500 EV tax credit, many were happy to see the rules had been changed slightly, as deliveries could occur after the September 30 cutoff as long as orders were placed before the end of that month.
However, there appears to be a new threshold that EV buyers will have to go through, and it will impact their ability to get the credit, at least at the Point of Sale, for now.
Delivery must be completed by the end of the year, and buyers must take possession of the car by December 31, 2025, or they will lose the tax credit. The U.S. government will be closing the tax credit portal, which allows people to claim the credit at the Point of Sale.
🚨UPDATE: $7,500 Tax Credit Portal “Closes By End of Year”.
This is bad news for pending Tesla buyers (MYP) looking to lock in the $7,500 Tax Credit.

If not, the order can still go through, but the buyer will not be able to claim the tax credit, meaning they will pay full price for the vehicle.
This puts some buyers in a strange limbo, especially if they placed an order for the Model Y Performance. Some deliveries have already taken place, and some are scheduled before the end of the month, but many others are not expecting deliveries until January.

Elon Musk takes latest barb at Bill Gates over Tesla short position
Bill Gates placed a massive short bet against Tesla of ~1% of our total shares, which might have cost him over $10B by now
Elon Musk took his latest barb at former Microsoft CEO Bill Gates over his short position against the company, which the two have had some tensions over for a number of years.
Gates admitted to Musk several years ago through a text message that he still held a short position against his sustainable car and energy company. Ironically, Gates had contacted Musk to explore philanthropic opportunities.

Musk said he could not take the request seriously, especially as Gates was hoping to make money on the downfall of the one company taking EVs seriously.
The Tesla frontman has continued to take shots at Gates over the years from time to time, but the latest comment came as Musk’s net worth swelled to over $600 billion. He became the first person ever to reach that threshold earlier this week, when Tesla shares increased due to Robotaxi testing without any occupants.
Musk refreshed everyone’s memory with the recent post, stating that if Gates still has his short position against Tesla, he would have lost over $10 billion by now:

Just a month ago, in mid-November, Musk issued his final warning to Gates over the short position, speculating whether the former Microsoft frontman had still held the bet against Tesla.
“If Gates hasn’t fully closed out the crazy short position he has held against Tesla for ~8 years, he had better do so soon,” Musk said. This came in response to The Gates Foundation dumping 65 percent of its Microsoft position.

Musk’s involvement in the U.S. government also drew criticism from Gates, as he said that the reductions proposed by DOGE against U.S.A.I.D. were “stunning” and could cause “millions of additional deaths of kids.”
“Gates is a huge liar,” Musk responded.
It is not known whether Gates still holds his Tesla short position.
