The Tesla Model S recently dominated an extreme cold-weather testing study performed by Norweigan outlet Motor, accumulating 530 kilometers (329.327 miles) in some of the harshest Winter conditions available.
Of the twenty-nine electric vehicles tested during the assessment, the Model S was the only vehicle to achieve at least 450 kilometers of real-world driving range in frigid temperatures and snowy terrain.

The study utilized a variety of EVs from several different manufacturers. Tesla Model S “Standard,” Model X Plaid, and Model Y Rear-Wheel-Drive vehicles participated in the study, with Mercedes EQE 300, BMW i7, Volkswagen’s ID.5 and ID.BUZZ also taking part.
The publication broke down how it tests vehicles to maintain a fair and equal opportunity for desirable results. The test is performed every six months, winter and summer, following the same route:
“A loop through Oslo, up Rv4 to Gjøvik, from there E6 up to Hjerkinn, then east and around Rondane over Venabygdsfjellet, down to Ringebu and up E6 again.”

The cars are driven at the speed limit until their charge is depleted, and no driver support systems, such as cruise control, are permitted during the test.
Impressive in its own right, the Model S achieved a massive 530 kilometers of range on a single charge. Despite only being charged 98 percent “due to a technical problem,” the Model S Dual Motor All-Wheel Drive didn’t have a very close competitor. In fact, the vehicle that came closest was the Tesla Model X Plaid, which achieved 444 kilometers (275.889 miles). Right behind it were the BMW i4 and NINE ET7, which both achieved 434 kilometers before depleting their travel distance.
The Model S also had one of the lowest deviations from its WLTP range ratings, coming in at 16.40 percent. Of the top ten performing vehicles, the Model S had the lowest, with the Model X coming in second with 18.23 percent.
| Model | WLTP range | Achieved range | Percentage deviation, range |
| Tesla Model S Standard | 634 | 530 | -16.40% |
| Mercedes EQE 300 | 614 | 409 | -33.39% |
| BMW i7 xDrive60 | 595 | 424 | -28.74% |
| NINE ET7 | 580 | 434 | -25.17% |
| BMW i4 eDrive40 | 565 | 434 | -23.19% |
| Tesla Model X Plaid | 543 | 444 | -18.23% |
| Nissan Ariya 2WD | 533 | 400 | -24.95% |
| Volkswagen ID.5 Pro | 526 | 378 | -28.14% |
| Bid Han | 521 | 406 | -22.07% |
| Hongqi E-HS9 prototype 120 kWt | 515 | 389 | -24.47% |
Tesla has battled range loss in colder climates with a variety of techniques, including the most notable, which is the heat pump.
After including the heat pump on the Model Y, Tesla eventually implemented it on its three other vehicles, with the Model S and Model X receiving the addition with its Refreshed cars in 2021.
Elon Musk once said the heat pump was “some of the best engineering I’ve seen in a while.” It was developed by Joseph Mardall and other members of the Tesla engineering team. Mardall left Tesla in early 2021 to join Zipline, a robotics and autonomy-focused logistics company.
Another fun fact: the Model S beat the record set by the 2021 Tesla Model 3 Dual Motor Long Range, which made it 521 kilometers (323.734 miles).

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.
It may also engage if we…

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.
