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 Semi’s official battery capacity leaked by California regulators
A California regulatory filing just confirmed the exact battery size inside each Tesla Semi variant.
A regulatory filing published by the California Air Resources Board in April 2026 has put official numbers on what Tesla Semi owners and fleet buyers have long wanted confirmed: the exact battery capacities of both the Long Range and Standard Range Semi truck variants. CARB is California’s independent air quality regulator, and it certifies zero-emission powertrains before they can be sold or operated in the state. When a manufacturer submits a vehicle for certification, the resulting executive order becomes a public document, making it one of the most reliable sources for confirmed production specs on any EV.
The document lists two certified powertrain configurations. The Long Range Semi carries a usable battery capacity of 822 kWh, while the Standard Range version comes in at 548 kWh. Both use lithium-ion NCMA chemistry and share the same peak and steady-state motor output ratings of 800 kW and 525 kW respectively. Cross-referencing Tesla’s published efficiency figure of approximately 1.7 kWh per mile under full load, the 822 kWh pack supports roughly 480 miles of real-world range, which aligns closely with Tesla’s advertised 500-mile figure for the Long Range trim. The 548 kWh Standard Range pack works out to approximately 320 miles, again consistent with Tesla’s stated 325-mile target.
Here is a direct comparison of the two versions based on the CARB filing and published specs:
| Tesla Semi Spec | Long Range | Standard Range |
| Battery Capacity | 822 kWh | 548 kWh |
| Battery Chemistry | NCMA Li-Ion | NCMA Li-Ion |
| Peak Motor Power | 800 kW | 525 kW |
| Estimated Range | ~500 miles | ~325 miles |
| Efficiency | ~1.7 kWh/mile | ~1.7 kWh/mile |
| Est. Price | ~$290,000 | ~$260,000 |
| GVW Rating | 82,000 lbs | 82,000 lbs |
The timing of this certification is not incidental. On April 29, 2026, Semi Programme Director Dan Priestley confirmed on X that high-volume production is now ramping at Tesla’s dedicated 1.7-million-square-foot facility in Sparks, Nevada. A key advantage of the Nevada location is vertical integration: the 4680 battery cells powering the Semi are manufactured in the same complex, eliminating the supply chain bottleneck that had delayed the program for years.
Tesla’s long-term goal is to reach a production capacity of 50,000 trucks annually at the Nevada factory, which would represent roughly 20 percent of the entire North American Class 8 market. With CARB certification now in hand and the production line running, the regulatory and manufacturing groundwork for that target is in place.
Tesla became the first company to pass the United States government’s new Advanced Driver Assistance Systems (ADAS) testing with the Model Y, completing each of the new tests with a passing performance.
In a landmark announcement on May 7, the National Highway Traffic Safety Administration (NHTSA) declared the 2026 Tesla Model Y the first vehicle to pass its newly ADAS benchmark under the New Car Assessment Program (NCAP).
Model Y vehicles manufactured on or after November 12, 2025, met rigorous pass/fail criteria for four newly added tests—pedestrian automatic emergency braking, lane keeping assistance, blind spot warning, and blind spot intervention—while also satisfying the program’s original four ADAS requirements: forward collision warning, crash imminent braking, dynamic brake support, and lane departure warning.
The NHTSA has just officially announced that the 2026 @Tesla Model Y is the first vehicle model to pass the agency’s new advanced driver assistance system tests.

NHTSA administration Jonathan Morrison hailed the achievement as a milestone:
“Today’s announcement marks a significant step forward in our efforts to provide consumers with the most comprehensive safety ratings ever. By successfully passing these new tests, the 2026 Tesla Model Y demonstrates the lifesaving potential of driver assistance technologies and sets a high bar for the industry. We hope to see many more manufacturers develop vehicles that can meet these requirements.”
The updates to NCAP, finalized in late 2024 and effective for 2026 models, reflect growing recognition that ADAS features are no longer optional luxuries but essential tools for preventing crashes.
Pedestrian automatic emergency braking, for instance, targets one of the fastest-rising causes of roadway fatalities, while blind spot intervention and lane keeping assistance address common sources of side-swipes and run-off-road incidents. By incorporating objective, performance-based evaluations rather than mere presence of the technology, NHTSA aims to give buyers clearer data on real-world effectiveness.
This milestone arrives at a pivotal moment when vehicle autonomy is transitioning from science fiction to everyday reality.
Tesla’s Full Self-Driving (FSD) software and the impending rollout of robotaxis underscore a broader industry shift toward higher levels of automation. Yet regulators and consumers remain cautious: safety data must keep pace with technological ambition.
The Model Y’s perfect score on these ADAS benchmarks validates that current driver-assist systems—when engineered rigorously—can dramatically reduce human error, which still accounts for the vast majority of crashes.
For Tesla, the result reinforces its long-standing claim of building the safest vehicles on the road. More importantly, it signals to the entire auto sector that meeting elevated federal standards is achievable and expected.
As autonomy edges closer to Level 3 and beyond, where drivers may disengage more fully, such independent verification becomes critical. It builds public trust, informs purchasing decisions, and accelerates the development of systems that could one day eliminate tens of thousands of annual traffic deaths.
In an era when software-defined vehicles promise transformative mobility, the 2026 Model Y’s NHTSA triumph is more than a manufacturer accolade—it is a regulatory green light that autonomy’s future must be built on proven, testable safety foundations. The bar has been raised. The industry, and the roads we share, will be safer for it.
Tesla is going to fix the nearly 219,000 vehicles that it recalled due to an issue with the rearview camera with a simple software update, giving owners no need to travel to a service center to resolve the problem.
Tesla is formally recalling 218,868 U.S. vehicles after regulators discovered a software glitch that can delay the rearview camera image by up to 11 seconds when drivers shift into reverse.
The affected models include certain 2024-2025 Model 3 and Model Y, as well as 2023-2025 Model S and Model X vehicles running software version 2026.8.6 and equipped with Hardware 3 computers. The National Highway Traffic Safety Administration (NHTSA) determined the lag violates Federal Motor Vehicle Safety Standard 111 on rear visibility and could increase crash risk.
Yet this is no ordinary recall. Owners do not need to schedule a service-center visit, hand over keys, or wait for parts.
Tesla fans call for recall terminology update, but the NHTSA isn’t convinced it’s needed
Tesla identified the issue on April 10, halted further deployment of the faulty firmware the same day, and began pushing a corrective over-the-air (OTA) software update on April 11.
By the time the NHTSA posted the recall notice on May 6, more than 99.92 percent of the affected fleet had already received the fix. Tesla reports no crashes, injuries, or fatalities linked to the glitch.
The episode underscores a deeper problem with regulatory language. For decades, “recall” meant hauling a vehicle to a dealership for hardware repairs or replacements. That definition no longer fits software-defined cars. When a fix arrives wirelessly in minutes — identical to an iPhone update — the term evokes unnecessary alarm and misleads the public about the actual risk and remedy.
Elon Musk has repeatedly called for exactly this change. After earlier NHTSA actions, he stated plainly: “The terminology is outdated & inaccurate. This is a tiny over-the-air software update.” On another occasion, he added that labeling OTA fixes as recalls is “anachronistic and just flat wrong.”
The terminology is outdated & inaccurate. This is a tiny over-the-air software update. To the best of our knowledge, there have been no injuries.
— Elon Musk (@elonmusk) September 22, 2022
Musk’s point is simple: regulators must evolve their vocabulary to match the technology. Traditional recalls involve physical intervention and downtime; OTA updates do not. Retaining the old label distorts consumer perception, inflates perceived defect rates, and slows the industry’s shift to faster, safer software iteration.
Tesla’s rapid, remote remedy demonstrates the safety advantage of over-the-air capability. Problems that once required weeks of dealer appointments are now resolved in hours, often before most owners notice. As more automakers adopt software-first designs, the entire regulatory framework needs to catch up.
Updating “recall” terminology would align language with reality, reduce public confusion, and recognize that modern vehicles are no longer static hardware — they are continuously improving computers on wheels.
For the 219,000 Tesla owners involved, the process is already complete. The camera works, the car is safe, and no one left their driveway. That is the new standard — and the vocabulary should reflect it.
