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 AI lead Ashok Elluswamy said this week that 24-hour Robotaxi service is close. Replying on X to a rider who wanted Cybercab trips all night, he wrote that the capability would arrive “next month or so” once “the next tech to merge on the v15 plan” is ready.
The comment landed on September 4, one day after Tesla opened public Cybercab rides in Austin. It is the clearest near-term timeline yet for overnight unsupervised operation. Tesla’s paid Robotaxi network currently runs from 6 a.m. to 10 p.m. seven days a week across Austin, Dallas, Houston, Miami, Orlando, and Tampa.
next month or so. the next tech to merge on the v15 plan will enable it.

That 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.
Elluswamy did not name the specific feature or say whether the change would apply first to purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list. The link to Full Self-Driving v15 is nevertheless significant.
Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.
By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states with what the company called an impeccable safety record and no notable incidents caused by the vehicles themselves. Tesla has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.
Overnight service would test that claim in lower-light conditions and would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.
Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale: Tesla has held back mass expansion until more of the v15 stack is merged, citing the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.
If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets.
That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.

The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.
