Tesla’s edge in battery and charging tech emerges in Model X vs Jaguar I-PACE range test
With just 15 years of experience under its belt, Tesla remains a neophyte in the automotive industry. Despite its short tenure, the upstart electric car maker continues to establish itself as a leader in battery technology and charging infrastructure. Tesla’s advantages in these fields became prominent in a real-world test between the Model X 90D and the Jaguar I-PACE in Germany earlier this month, when the two vehicles went head-to-head in a battery consumption and charging test.
Batteries are a core part of Tesla’s business. Since the days of the original Roadster, Tesla has gone all-in with its battery technology, from the Model S and X’s 18650 cells to the Model 3’s more energy-dense 2170 cells. The same is true for Tesla’s Supercharger Network. The Silicon Valley-based carmaker has invested heavily in the expansion of its charging infrastructure, to the point where the company’s vehicles today are among the few electric cars that are almost as convenient as fossil fuel-powered vehicles for long-distance driving.
The Jaguar I-PACE is an all-electric crossover SUV that boasts plush interior accents and a 90 kWh battery. With its large battery pack, Jaguar estimates that the I-PACE should be able to travel up to 240 miles per charge. The vehicle is also compatible with DC rapid chargers, including the upcoming IONITY Network, which is capable of providing an output of up to 350 kW. As shown by a range and battery consumption test by German YouTube channel nextmove, though, it appears that the I-PACE’s highway consumption and charging speed leaves much to be desired.
The publication opted to drive both vehicles on the Autobahn at highway speeds, traveling from Jena to Berlin (a distance of 268 km/166 miles). With both vehicles having a 90 kWh battery pack, and with the Model X being larger and heavier, it initially seemed like the I-PACE would have no problem keeping pace with the American-made all-electric SUV. Midway through the test, though, it became evident that the Jaguar I-PACE, despite being smaller and lighter, was less efficient than the Model X. At speeds between 93 km/h (58 mph) and 110 km/h (68 mph), for example, the I-PACE showed an average consumption of 22.5 kWh/100 km (362 Wh/mi). The Model X, on the other hand, had a consumption of 17.5 kWh/100 km (282 Wh/mi). That makes the larger, heavier Model X around 23% more efficient than the Jaguar I-PACE.
The Tesla Model X also outshone the Jaguar I-PACE in terms of charging. The German publication opted to charge the I-PACE at an IONITY station in a Porsche dealership. IONITY’s stations are capable of proving up to 350 kW of output, but despite this, the I-PACE was limited to only 80-83 kW. In contrast, Tesla’s Supercharger Network was able to recharge the Model X 90D with more than 100 kW of output.
While Tesla’s superior battery tech and charging system were notable in the Model X versus Jaguar I-PACE test, it should be noted that the Model X in nextmove‘s video was still equipped with Tesla’s legacy 18650 battery cells, which are incredibly reliable but not as energy-dense as the 2170 cells found in the Model 3. Tesla’s 2170 cells have garnered rave reviews from auto veterans such as Sandy Munro, who noted that the batteries are superior to those currently in the market. Tesla will inevitably roll out its 2170 cells to the Model S and Model X, and once it does, legacy carmakers like Jaguar would likely find themselves chasing a moving target. This was mentioned by Tesla CEO Elon Musk in the third quarter earnings call, when he noted that the Model 3 is currently the “most efficient energy per mile electric vehicle out there.”
“We’ve got the best in terms of miles or kilometers per kilowatt hour, and we also have the lowest cost per kilowatt hour. This makes it very difficult for other companies to compete with Tesla because we’re the most efficient car and the lowest-cost batteries. So I do encourage our competitors to really make a huge investment. And we’ve been saying that for a long time. And then they are only in this competitive disadvantage because they didn’t. We try to help them as much as we could, and they didn’t want to take our help.
“They can use our Supercharger network if they can just have an adapter for our — connector or something. We want to be as helpful as possible to the rest of the industry. The fact of the matter is we made the investment in the Gigafactory, and other companies didn’t. And we put a lot of effort into having extremely efficient cars, which are having the most efficient powertrains, and the other companies didn’t. But that’s what has put us in quite a strong competitive position right now.”
Back when Elon Musk outlined his plans for starting Gigafactory 1 as a facility specifically designed to manufacture batteries for Tesla’s electric cars; many were skeptical. In 2014, for example, the MIT Technology Review published an article expressing reservations about the project, arguing that the Gigafactory would be a risky gambit for Tesla since it would be difficult to determine if demand for Tesla’s electric cars would be consistent. The Supercharger Network was largely dismissed by the company’s skeptics as well, with critics stating that once other automakers like GM decide to go all-in on the electric car movement, they would be able to leapfrog Tesla’s charging system. As legacy carmakers are coming to the realization that it is not so easy to build electric cars, and as vehicles like the I-PACE lag behind Tesla’s legacy battery technology in the Model X 90D, it seems like Elon Musk’s “I told you so” moment in the past earnings call was well-justified.

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.
