Rivian has officially launched the next-generation R1S and R1T, new versions of the company’s flagship electric vehicles.
“We continue to evolve our flagship R1 vehicles,” CEO RJ Scaringe said, “offering quality and performance without compromise. Our revamped R1S and R1T push the technical boundaries further, creating our most capable products to date.”
Rivian aimed to refine and improve performance, design, range, and overall ownership experience with the new R1T and R1S, bringing everything from new drivetrains to new interior aesthetics to the EVs without compromising any of the features that owners loved about the first generation.
Additionally, Rivian is rolling out its new Autonomy Platform, which was developed in-house and utilizes eleven internally developed cameras along with five radars that perform over 250 trillion operations per second.
“For most owners, their R1 Gen 2 will be the most powerful computer that they own,” VP of Autonomy and AI for Rivian, James Philbin, said.
Let’s dive into some of the improvements Rivian has employed:
Performance
Rivian’s next-gen R1 platform now features more power, performance, and range, all stemming from a new drive unit offered in its Tri and Quad-Motor configurations. Dual-Motor has not gone anywhere either, and still offers great performance metrics:
- Dual-Motor Our Dual-Motor delivers incredible all-wheel drive capability along with 665 horsepower and 0–60 mph in as quick as 3.4 seconds for the Performance variant
- Tri-Motor Our all-new 850 horsepower Tri-Motor packs two motors in the rear and one in front for a blend of exceptional power and range. The Tri-Motor R1T delivers 0–60 mph in 2.9 seconds while offering an estimated range of 380 miles. In Conserve Mode, the estimated range is up to 410 miles.
- Quad-Motor For peak adventure, our new 1,025 horsepower Quad-Motor delivers 0–60 mph in less than 2.5 seconds in R1T — and ¼ mile in 10.5 seconds — with a staggering 1,198 lb-ft of torque when using Launch Mode. 60–80 mph acceleration is 1.5 seconds, with incredible torque control at each wheel for superior on-road performance and off-road capability.
Ride and Handling
Rivian also focused on the ride and handling experience in the R1 lineup for this second-generation vehicle launch. The suspension system has been fully re-engineered, improving on what customers called a “sport-tuned feel” in the first-generation EVs. Rivian decided to go with a “smoother” ride for the new R1T and R1S, which is adjustable to ensure comfortable on and off-road capabilities.
Vehicle equipment has also been refined. Rivian developed new wheels and fitted them with new tires, including a redesigned 22″ aerodynamic wheel design and Pirelli-developed tires to increase range.
For Performance, Rivian is going with an Ultra-High-Performance Michelin tire that will be available on the Quad-Motor configurations. Additionally, for a “well-rounded” experience, Goodyear has a 20″ ADV tire that offers “balanced all-around capability with the rolling-resistance of an all-season,” and comes standard.
Range and Batteries
Three battery pack sizes will still be offered by Rivian, but the Max and Large batteries have been completely re-engineered and offer ranges of 420 and 330 miles, respectively, based on estimations. They will continue to use 2170 cylindrical cells, and the pack enclosure features a “large high-pressure de-casting” system to simplify manufacturing and reduce mass.
The new Standard Pack will feature lithium-iron-phosphate (LFP) chemistry and provide an EPA-estimated 270-mile range.
140 miles of range can be regained in as little as 20 minutes and are compatible with all major public high-speed charging networks. This includes the Rivian Adventure Network and the Tesla Supercharger Network.
Design and Experience
Rivian honed in on new features with the R1T and R1S and also added two new premium interiors, new exterior paint options, and new darkout trim options.
These are in addition to the new wheel and tire choices, and now vehicles come with a new electronically tinted glass roof, new in-cabin storage, interior lighting themes, new digital interfaces, and new cell shading designs for the different drive modes. It has also improved on the wireless charger.
Surround Sound Audio with Dolby Atmos is available with Rivian Premium Audio.
Refined Electrical Architecture and Compute Platform
The second-gen R1 features new electrical architecture and a new compute platform that was developed in-house by the Rivian hardware and software teams.
“While the exterior of the R1 looks similar, the electrical system is completely redone, providing a significant increase in features as well as a dramatic increase in sensing and compute capability,” Rivian’s SVP of Electrical Hardware, Vidya Rajagopalan, said.
Trimming the ECU count from 17 in the first-gen to just 7 in the second-gen, the “massive simplification” was part of a shift in zonal architecture. Infotainment, autonomy, and vehicle access, as well as battery management, all have their own ECUs. Every other vehicle function is controlled by the remaining three.
Rivian Autonomy Platform
The Rivian Autonomy Platform utilizes “11 internally developed cameras and five radars performing over 250 trillion operations per second, an industry-leading level of compute power.”
The cameras are high-resolution and now include 4K HDR units, which have 360-degree visibility and can see three-times farther than the previous system, as well as 10 seconds ahead at highway speeds.
These are the most camera megapixels of any EV in North America and enable improved dynamic range and clear vision in high-contrast scenarios, like tunnel entrances and exits.
Rivian is also utilizing a cabin-facing camera in the rearview mirror to detect both driver fatigue and distraction when operating in Enhance Highway Assist mode, which will roll out later this year.
The Autonomy Compute Module is backed up by dual NVIDIA DRIVE Orin processors, delivering 10 times more compute performance than the previous system.
Pricing
The new R1S will start at $75,900 and the R1T at $69,900. Dual-Motor configurations can be ordered today and are available immediately. Tri-Max is expected to be launched in the late Summer, while Quad Max will come shortly after.

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.
