Tesla Model S, 3, X takes on Audi e-tron in Autobahn range and efficiency test
German electric vehicle rental company nextmove recently conducted what could only be described as the ultimate Autobahn efficiency and range test, pitting the Tesla Model S, 3, and X against the upstart Audi e-tron and the bang-for-your-buck Hyundai Kona Electric. Following the EV rental firm’s test, it was evident that veteran automakers such as Audi still have a long way to go before they catch up to Tesla’s experience in electric cars.
Eight vehicles were used for nextmove’s test: a Model S 100D (equipped with 19” winter tires), two Tesla Model X 100D (one fitted with 19” winter tires and the other fitted with 20” summer tires), one Tesla Model 3 Dual Motor AWD (equipped with 19” summer tires), two Audi e-tron (one with digital side mirrors and another with classic mirrors; both equipped with 21” summer tires), and two Hyundai Kona Electric (one fitted with 17” summer tires and the other fitted with 17” winter tires). Each vehicle’s tire pressure was set according to manufacturer specifications, and each was driven by an experienced electric car driver.

Several rules were observed to keep the Autobahn test as controlled as possible. Cruise control was only utilized once the target cruising speed of 130 kph (81 mph) and 150 kph (93 mph) was reached. Features such as Regenerative Braking were also avoided, and heating was largely disabled. Thet route was 85 km (52.8 miles) long, with the vehicles traveling 130 kph one way and 150 kph in the other.
The results of both the 130 kph (81 mph) and 150 kph (93 mph) tests revealed that the Tesla Model 3 was the most efficient vehicle among the eight that the EV rental company evaluated. Following the Model 3 was the Hyundai Kona Electric in summer tires, which is, in turn, followed by the Tesla Model S 100D. The largest vehicle in the group, the Tesla Model X, proved less efficient than the Model 3, Model S, and Kona Electric, but it proved notably more efficient than the Audi e-tron.

The Audi e-tron and the Tesla Model X had already gone head-to-head in a nextmove test in the past. During the previous test, the EV rental company utilized a pre-production version of the Audi e-tron, and it proved to be the electric equivalent of a gas-guzzler, being 23% less efficient than the larger, heavier Tesla Model X.
While the Audi e-tron performed much better against the Tesla Model X than its pre-production counterpart in the recent test, the all-electric SUV still proved less efficient than the Silicon Valley-made crossover. Quite interestingly, the difference in energy consumption between the Tesla Model X and Audi e-tron was more prominent at lower speeds than at higher speeds.

Tesla’s Model S, 3, and X cleared the house in terms of range. During the 130 kph test, the Model S 100D showed a range of 480 km (298 miles), the Model X 100D showed a range of 409 km (254 miles), and the Model 3 managed a range of 406 km (252 miles). The Hyundai Kona Electric turned in a respectable 322 km (200 miles), and the Audi e-tron, in last place, managed 301 km (187 miles).
The results of the 150 kph test were quite similar. The Model S, X and 3 proved superior once more with a range of 428 km (265 miles), 359 km (223 miles), and 358 km (222 miles). The Hyundai Kona Electric managed 283 km (176 miles), while the Audi e-tron achieved a range of 275 km (171 miles). With these results in mind, it appears that veteran automakers such as Audi still have their work cut out for them in terms of designing electric vehicles that offer a balance of power, efficiency, and range.

It should be noted that the Tesla Model X utilized by nextmove in its Autobahn efficiency test was a 100D unit, and thus, the vehicle was not yet equipped with the company’s updated high-efficiency drive units. With a “Raven” Model S and Model X in the equation, the German EV rental company’s test could very well have ended in a far more lopsided manner.

Tesla finally got its Nevada Robotaxi Permit but with a few catches hard to miss
Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.
Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.
Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.
Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.
Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.

Tesla launches Powerwall Lease for affordable home backup
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again
Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.
