Tesla Model S “Refresh” spied track testing
New photos from the Tesla Fremont Factory obtained by Teslarati show the new Refreshed Tesla Model S and its new features, confirming the long-time speculation of whether the company’s flagship sedan would be updated nine years after its initial release. After the Plaid Model S was announced in 2019, slight cosmetic modifications were added to the car to increase aerodynamic performance in a track setting. Some of these new features included a wider body, a rear diffuser, and a spoiler. Tesla has made several changes to the Refreshed Model S, as seen in the photos below. The vehicle was spotted at both the Fremont Test Track and on public roads when the photographs were taken.
For those who are unfamiliar, Tesla operates its own test track behind the Fremont factory for its vehicles. In 2013, three years after Tesla’s purchase of the Fremont factory from GM, the electric automaker bought the 35-acre property that included the test track from the Union Pacific Railroad. It is located adjacent to the Fremont factory, so Tesla can take cars that need to be tested to the track within a few minutes. In the past, Tesla has tested vehicles like the Model Y and the 2020 Roadster at the track prior to their release, indicating that the new Model S that was spotted could be on its way to the company’s Design Studio shortly.
Initial rumors of the Model S refresh emerged in late 2020 after several updates to the Model 3 and Model Y vehicles. While the Model Y underwent several minor updates, like a new center console, new door paneling, and a heated steering wheel in China, the Model 3 was the subject of more noticeable cosmetic revisions. The mass-market sedan from Tesla was equipped with a full chrome delete kit that now comes standard, a new center console design, new headlights, double-paned glass, a powered trunk, and other interior revisions.
On the other hand, the Model S has only undergone one true cosmetic revision since its initial release nearly nine years ago: the removal of the nosecone. Since the vehicle has gone so many years without a real update or any major changes to its aesthetic qualities, Tesla may have decided it was time to “refresh” the car.
Now, photographs of the new Model S have been captured, showing a wider body, revised fog lights, new wheels, and several other cosmetic revisions.
A few of the more notable changes are a new front diffuser, a part that became standard with the newly-designed Plaid Model S. A diffuser displaces air underneath the vehicle’s body, increasing aerodynamic performance and making the flow of air more efficient during travel. Additionally, the front fascia has also been revised slightly. This is the second revision Tesla has made to this portion of the Model S since its release. The new design includes a larger central air intake vent for improved airflow and ventilation to the battery pack. This eliminates the possibility of overheating and improves battery lifetime and performance.

One of the more interesting and speculative details of the new Model S is that there is no touchscreen protruding from the top of the dash. The Model 3 and Model Y center dash screen can be seen from the outside of the vehicle when looking through the windshield. There is no evidence that Tesla is adopting the 3 and Y center touchscreen design for the Model S refresh. We are currently not aware of any modifications to the vertical touchscreen that has been standard on the Model S and Model X.
The fog lights located on the bottom of the front lip have also been modified, bringing a slightly new look to the lower lights. Additionally, new wheels appear to be on the Model S, and they look to be a revised version of the Arachnid wheels that Tesla included as a Referral Program reward back in 2016. Neither the 19″ Tempest Wheels nor the 21″ Sonic Carbon Twin Turbine Wheels that are available with the Plaid Model S matches the wheels that were equipped on the vehicle that was spotted at the Fremont Factory. This appears to confirm Tesla may also be releasing a new wheel design that will be included with the Refreshed Model S design.
It seems the refreshed Model S has adopted more features that are going to be included on the Plaid Model S, due to be released in late 2021. A wider fender design is paired with new, wider wheels. These modifications were first noticed on the Plaid Model S that was spotted running spirited laps at the Nürburgring in Germany in 2019.

Another interesting note is the side repeater cameras have been adjusted onto the new fenders, but only slightly. It appears Tesla has moved it forward toward the wheel well. This could be to increase visibility when the cameras are activated.
The final noticeable external revision is a new rear bumper design that is more robust than the original Model S design. This could be indicative that the black Model S in the photos we shared could be the Plaid Model S, as it also has a wider rear bumper. However, it does not have a rear diffuser installed underneath, meaning it could just be a refreshed design.

Tesla is holding its Q4 2020 Earnings Call on Wednesday and many enthusiasts believe the company will announce either a refresh to the Model S, or will indicate the Plaid Model S will be on its way soon. With the several external modifications that have been spotted thanks to the pictures above, we know that Tesla is working on a revised design for its flagship sedan. While no details are known about the interior as of yet, details will be shared as they are found.
The Kilowatts spotted some more photos of the unique Model S at Fremont, providing some additional perspective on what changes Tesla made to its flagship sedan.

Tesla’s golden era is no longer a tagline
Tesla “golden era” teaser video highlights the future of transportation and why car ownership itself may be the next thing to change.
The golden age of autonomous ridesharing is arriving, and Tesla is making sure we can all picture a future that looks like the future. A recent teaser posted to X shows a Cybercab parked outside a home, and with a clear message that your everyday life may soon look like this when the driverless vehicles shows up at your door.
Tesla has begun the rollout of its Robotaxi service across US cities, and the production of its dedicated, fully-autonomous Cybercab vehicle. The first Cybercab rolled off the Giga Texas assembly line on February 17, 2026, with volume production now targeted for this month. Additionally, the Robotaxi service built around it is already running, without human drivers, in US cities.
Tesla Cybercab production ignites with 60 units spotted at Giga Texas
The Cybercab is built without a steering wheel, pedals, or side mirrors, designed from the ground up for unsupervised autonomous operation. Musk described the manufacturing approach as closer to consumer electronics than traditional car production, targeting a cycle time of one unit every ten seconds at full scale.
Drone footage from April 13, 2026 captured over 50 Cybercab units on the Giga Texas campus, with several clustered near the crash testing facility. Musk has noted that Tesla plans to sell the Cybercab to consumers for under $30,000, and owners will be able to add their vehicles to the Tesla robotaxi network when not in personal use, potentially generating income to offset the vehicle’s purchase cost. That model changes the math on vehicle ownership in a meaningful way, making a car something closer to a depreciating asset that can also earn by paying itself off and generate a profit.
During Tesla’s Q4 earnings call, the company confirmed plans to expand the Robotaxi program to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The service already runs without safety drivers in Austin, and public road testing of the Cybercab has expanded to five states, including California, Texas, New York, Illinois, and Massachusetts.

Tesla’s last chance version of the flagship Model X is officially gone
The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Tesla enabled a last-chance version of its two flagship vehicles, the Model S and Model X, over the past few weeks. The Model X, the company’s original SUV, is officially gone.
Tesla has officially closed the book on its most exclusive send-off for the Model X. The limited-run Model X Signature Edition—priced at $159,420 before fees and limited to just 100 units—is now sold out, with reservations closed as of April 16.

The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Every unit featured an exclusive Garnet Red exterior paint, unique badging, and a standard six-seat configuration. With full Plaid powertrain specs—Tri-Motor All-Wheel Drive, over 1,000 horsepower, and blistering acceleration—it was positioned as a collector’s item for loyalists who wanted one last shot at owning a piece of Tesla history.
The timing is no coincidence.
Tesla announced earlier this year that it would discontinue regular production of both the Model S and Model X to repurpose the Fremont factory’s dedicated lines for mass production of its Optimus humanoid robots.
Elon Musk has repeatedly emphasized that Optimus could ultimately become more valuable to the company than its vehicle business, with ambitions to build hundreds of thousands of units annually.
The Signature Editions served as a final “runout” series: 250 for the Model S and only 100 for the Model X, all built to the highest Plaid specification before the line is converted.
Deliveries of the remaining Signature units are scheduled to begin in May 2026. For buyers who secured one, it’s the ultimate swan song for a vehicle that helped define Tesla’s early luxury EV dominance.
Launched in 2015, the Model X introduced falcon-wing doors, a panoramic windshield, and class-leading performance that turned heads and set benchmarks. While newer models like the Cybertruck and refreshed Model Y have taken center stage, the Model X Plaid remained a halo product for those seeking maximum range, space, and speed in an SUV package.
With inventory of standard Model X units already nearly exhausted across the U.S., the rapid sell-out of the Signature Edition underscores enduring demand for Tesla’s premium flagships even as the company pivots toward robotics and autonomy.
For enthusiasts, these 100 garnet-red SUVs will likely become instant collector’s items—tangible reminders of the vehicles that built the brand before Tesla’s next chapter fully begins. The last chance is gone, but the legacy endures.

Tesla Optimus V3 hand and arm details revealed in new patents
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
Tesla is planning to soon reveal its latest and greatest version of the Optimus humanoid robot, and a series of new patents for the hands and arms, with the former being, admittedly, one of the most challenging parts of developing the project.
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
The designs relocate heavy actuators to the forearm, route cables through a sophisticated wrist design, and employ innovative joint assemblies to achieve human-like dexterity while enabling lightweight construction and high-volume manufacturing.
Core Tendon-Driven Hand Architecture
The primary patent, which is titled “Mechanically Actuated Robotic Hand,” details a cable/tendon-driven system.
Actuators are positioned in the forearm rather than the hand. Each finger features four degrees of freedom (DoF), while the wrist adds two more.
Tesla’s Optimus V3 robot hand looks to have been revealed in a new international patent published today.
The patent describes a tendon/cable-driven hand:
• Actuators in the forearm
• Each finger has 4 degrees of freedom
• The wrist has 2 degrees of freedom
• Tendon-driven… pic.twitter.com/eE8xLEYSrx— Sawyer Merritt (@SawyerMerritt) April 16, 2026
Three thin, flexible control cables (tendons) per finger extend from the forearm actuators, pass through the wrist, and connect to the finger segments. Integrated channels within the finger phalanges guide these cables selectively—routing behind some joints and forward of others—to enable independent bending without unintended motion.
Patent diagrams illustrate thick cable bundles emerging from the wrist into the palm and fingers, with labeled pivots and routing guides. This setup closely mirrors human forearm-muscle and tendon anatomy, where most hand control originates proximally.
Advanced Wrist Routing Innovation
One of the standout features is the wrist’s cable transition mechanism. Cables shift from a lateral stack on the forearm side to a vertical stack on the hand side through a specialized transition zone.
Boom! @Tesla_Optimus 의 3세대 구조로 추정되는, 로봇 팔 및 관절에 대한 특허가 공개되었습니다.
아티클 작업에 들어가겠습니다.
1년 넘게 기다려 온, 정말 귀한 특허인데, 조회수 100만대로 터져줬으면 좋겠네요. 😉@herbertong @SawyerMerritt@GoingBallistic5 @TheHumanoidHub pic.twitter.com/CCEiIlMFSX

This geometry significantly reduces cable stretch, torque, friction, and crosstalk during combined yaw and pitch wrist movements — common failure points in simpler tendon systems that cause imprecise or jerky motion.
By minimizing these issues, the design supports smoother, more reliable multi-axis wrist operation, essential for complex real-world tasks.
Companion Patents on Appendage and Joint Design
Two supporting patents provide additional depth. “Robotic Appendage” covers the overall forearm-to-palm-to-finger assembly, with a palm body movably coupled to the forearm and finger phalanges linked by tensile cables returning to forearm actuators. Tensioning these cables repositions the phalanges precisely.
“Joint Assembly for Robotic Appendage” describes curved contact surfaces on mating structures paired with a composite flexible member. This allows smooth pivoting while maintaining consistent tension, enhancing durability, and simplifying assembly for mass production.
Executive Insights on Hand Development Challenges
Tesla executives have consistently described the hand as the most difficult component of Optimus.
Elon Musk has called it “the majority of the engineering difficulty of the entire robot,” emphasizing that human hands possess roughly 27–28 DoF with an intricate tendon network powered largely by forearm muscles. He has likened the challenge to something “harder than Cybertruck or Model X… somewhere between Model X and Starship.”
In mid-2025, Musk acknowledged that Tesla was “struggling” to finalize the hand and forearm design. By early 2026, he stated that the company had overcome the “hardest” problems, including human-level manual dexterity, real-world AI integration, and volume production scalability.
He estimated the electromechanical hand represents about 60 percent of the overall Optimus challenge, compounded by the lack of an existing supply chain for such precision components.
These patents directly tackle the acknowledged pain points: relocating actuators reduces hand mass and inertia for better speed and efficiency; advanced wrist routing and joint geometry address friction and crosstalk; and simplified, stackable parts visible in the diagrams indicate readiness for high-volume manufacturing.
Implications for Optimus Production and Leadership
Collectively, the patents portray the Optimus v3 hand not as a mere prototype, but as a production-oriented system engineered from first principles.
The 22-DoF architecture, forearm-driven tendons, and crosstalk-minimizing wrist deliver a clear competitive edge in dexterity. They align with Musk’s view that high-volume manufacturing is one of the three critical elements missing from most other humanoid projects.
For Optimus to become the most capable humanoid robot, its hand needed to replicate the useful and applicable design of the human counterpart.
These filings demonstrate that Tesla has transformed years of engineering challenges into patented, elegant solutions — positioning the company strongly in the race toward general-purpose robotics.
