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

The Tesla Team April 23, 2019

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 scores major court win as judge rejects race bias class action

The ruling means the 2017 lawsuit cannot proceed as a class action because plaintiff attorneys were unable to secure testimony commitments from at least 200 workers.

Tesla scored a significant legal victory in California after a state judge reversed a class certification in a high-profile race harassment case involving 6,000 Black workers at its Fremont plant. The ruling means the 2017 lawsuit cannot proceed as a class action because plaintiff attorneys were unable to secure testimony commitments from at least 200 workers ahead of a 2026 trial, a threshold the judge viewed as necessary to reliably represent the full group.

No class action

In a late-Friday order, California Superior Court Judge Peter Borkon concluded that the suit could not remain a class action, stating he could not confidently apply the experiences of a much smaller group of testifying workers to thousands of potential class members. His ruling reverses a 2024 decision by a different judge who had certified the case under the belief that a trial of that size would be manageable, as noted in a Reuters report.

The lawsuit was originally filed by former assembly-line worker Marcus Vaughn, who alleged that Black employees at Tesla’s Fremont factory were exposed to various forms of racially hostile conduct, including slurs, graffiti, and instances of disturbing objects appearing in work areas. Tesla has previously said it does not tolerate harassment and has removed employees found responsible for misconduct. Neither Tesla nor the plaintiffs’ legal team immediately commented on the latest ruling.

Tesla’s legal challenges

While the decertification narrows the scope of this particular case, Tesla still faces additional litigation over similar allegations. A separate trial involving related claims brought by a California state civil rights agency is scheduled just two months after the now-vacated class trial date. The company is also contending with federal race discrimination claims filed by the U.S. Equal Employment Opportunity Commission, alongside several individual lawsuits it has already resolved.

For now, the reversal removes the large-scale exposure Tesla would have faced in a unified class trial, shifting the dispute back to individual claims rather than a single mass action. The case is Vaughn v. Tesla, filed in Alameda County Superior Court.

Tesla Holiday Update is incoming, and the wishlist is Merry and Bright

There are a handful of big wishes, and we’ve seen a lot of different requests out there based on what owners are saying on social media. Nevertheless, what Tesla should bring and what Tesla will bring are two different things.

Tesla’s Holiday Update is going to be on its way soon, and although we have no idea what the company is planning to implement into vehicles with the 2025 iteration.

However, the wishlist is extensive, and owners are hoping to get a vast array of new features, both useful and artificial. That’s the fun thing about owning a Tesla — not everything is necessary, and it’s okay for your car to be fun.

🚨 All I Want for Christmas (in the Tesla Holiday Update) is:

1. More streaming platforms
2. Summon for Cybertruck
3. Easier Navigation adjustment for a preferred route instead of the optimal choice

What else? pic.twitter.com/qapS1jXAuB

In past years, Tesla has brought both useful things and fun things with the Holiday Update. The Custom Lock Sound, new Light Shows, and even High Fidelity Park Assist have all come in past updates, among many other things. But for 2025, people want even more, and here’s what we have seen most frequently thus far:

More Streaming Platforms

This is a personal request of ours, and it’s something that we feel is long overdue.

Sure, Netflix, Disney+, and Hulu are all great — but there’s a lot of meat left on that bone. HBOMax, Paramount+, and even YouTube TV would be a great option for those of us who have subscriptions and want to watch Live Events while Supercharging or eating in our cars.

The fact that Tesla has not added more platforms to its in-car Theater in a few years has been, dare I say, disappointing?

Full Self-Driving for Europe

This is something not even Santa can help with. Although his Elves are known for their high productivity, we’re not even sure they could convince European regulators to open the door for FSD’s entrance into the market.

Tesla deploys Unsupervised FSD in Europe for the first time—with a twist

FSD is definitely capable of handling European driving conditions, but regulators are truly dragging their feet through the mud with the approval process. Tesla has tested FSD in several countries in Europe, but nothing has been set in stone yet.

Deeper Grok Integration

Many owners have said something about how Grok is truly not super in-tune with the vehicles. This is something any owner will experience.

It seems Grok should be capable of handling all in-car requests; everything from changing the A/C to a specific temperature to adding a stop within the Navigation should be handled by Grok.

Instead, Grok cannot handle those things currently. You have to speak to the car itself using the microphone button on the steering wheel.

Interestingly, some vehicles already have the Grok logo replacing the microphone. It is likely the most realistic request of all.

‘Learn’ Mode for Full Self-Driving Arrival Options

Although it is great for public destinations, FSD still does not allow you to choose a set parking spot at your residence. It also does not allow you to choose preferences for parking in large parking lots.

Renters, and even those who live in purchased townhomes, often have assigned parking spots. Full Self-Driving v14 has done a great job of doing half the work, but there have been too many times when I’ve arrived home, the car pulls me into a spot, and I’m forced to manually back out and park in my assigned space.

Many people also do not like to park toward the entrance of a store, me included. Parking away from the front of a store eliminates parking congestion and usually is a safer bet for your vehicle to keep from being dinged by careless drivers who swing their doors open.

Navigation Adjustments

Sometimes you don’t want to turn left on the street the navigation chooses. Maybe you want to go a block down and check out that new Portuguese restaurant that just opened on the way to your next destination.

This is only possible currently by inputting a waypoint that would take you that way. Instead, the center screen could be opened, and the driver should be able to select an alternative route by simply touching a street they’d rather travel on.

Tesla received another round of bullish analyst updates this week, led by Stifel, raising its price target to $508 from $483 while reaffirming a “Buy” rating. The firm cited meaningful progress in Tesla’s robotaxi roadmap, ongoing Full Self-Driving enhancements, and the company’s long-term growth initiatives.

Robotaxi rollout, FSD updates, and new affordable cars

Stifel expects Tesla’s robotaxi fleet to expand into 8–10 major metropolitan areas by the end of 2025, including Austin, where early deployments without safety drivers are targeted before year-end. Additional markets under evaluation include Nevada, Florida, and Arizona, as noted in an Investing.com report. The firm also highlighted strong early performance for FSD Version 14, with upcoming releases adding new “reasoning capabilities” designed to improve complex decision-making using full 360-degree vision.

Tesla has also taken steps to offset the loss of U.S. EV tax credits by launching the Model Y Standard and Model 3 Standard at $39,990 and $36,990, Stifel noted. Both vehicles deliver more than 300 miles of range and are positioned to sustain demand despite shifting incentives. Stifel raised its EBITDA forecasts to $14.9 billion for 2025 and $19.5 billion for 2026, assigning partial valuation weightings to Tesla’s FSD, robotaxi, and Optimus initiatives.

TD Cowen also places an optimistic price target

TD Cowen reiterated its Buy rating with a $509 price target after a research tour of Giga Texas, citing production scale and operational execution as key strengths. The firm posted its optimistic price target following a recent Mobility Bus tour in Austin. The tour included a visit to Giga Texas, which offered fresh insights into the company’s operations and prospects.

Additional analyst movements include Truist Securities maintaining its Hold rating following shareholder approval of Elon Musk’s compensation plan, viewing the vote as reducing leadership uncertainty.
