Auto experts reveal why Tesla’s batteries hold a comfortable lead in range
One of the reasons why the narrative of the “Tesla Killer” has effectively died is due to the pervading lead that Tesla holds over the competition in terms of range. Amidst the long-predicted entrance of competing vehicles from established automakers including Audi, Jaguar, and Porsche, Tesla’s vehicles have proven to be vastly superior in range, as evidenced by the Model S Long Range, which can last 370 miles in between charges.
Take Tesla’s very first car, the original Tesla Roadster. The vehicle featured Tesla’s efforts at creating a desirable all-electric sports car, and it showed in the Roadster’s robust 245-mile range. There weren’t even Superchargers when the Roadster was released, but the car proved that EVs could comfortably go beyond the 200-mile mark, and then some more. Interestingly, even modern EVs from veteran carmakers are finding it hard to match the Roadster’s 245-mile EPA range. The Audi e-tron, for example, just has 204 miles of range per charge, while the award-winning I-PACE has an EPA rating of 234 miles per charge.
This, according to veteran auto experts Sandy Munro and Mark Ellis of Munro & Associates, has a lot to do with Tesla’s all-electric platform and the company’s proprietary battery tech. Tesla is only 16 years old, and thus, it only has a fraction of the experience that its rivals in the auto market has. Yet in the EV segment, Tesla is among the veterans, having worked solely on electric cars since Day One.
All-Electric
As such, vehicles that Tesla releases such as the Model S, Model X, and Model 3, are designed as EVs from the get-go. In contrast, carmakers such as Mercedes-Benz and Audi opted to convert existing platforms for EV production. This reduces costs, but it is a double-edged strategy in the EV segment, which is starting to gain serious ground in several key markets. “If you’re designing something radically different, or if you want to have something that’s going to be a world-beater in the marketplace, that parts bin is the worst thing imaginable,” Munro said.
This could be seen in the difference between the Porsche Taycan and a vehicle such as the Mercedes-Benz EQC. Porsche opted to design the Taycan from a clean sheet, and the result was an all-electric sports car that can attack the track just as aggressively as the next 911. It even has a frunk like a Tesla, albeit smaller. Mercedes, on the other hand, opted to base the EQC on its existing GLC platform, and the result is an EV that still has echoes of its internal combustion roots. Between the two vehicles, it is easy to see which carmaker put more effort, and it shows. Today, it appears that the non-Tesla EV community is far more excited about the Taycan than they are for the EQC.
Mark Ellis, a senior master of lean design and battery consultant, notes that this is a key advantage that is inherent in Tesla. “One of Elon Musk’s big advantages is, basically, that the vehicle is designed to be an electric car. Musk designed every aspect of this car to be as efficient as possible,” he said.
The Secret Sauce
Apart from their all-electric design, Tesla’s secret sauce for its vehicles lies in their batteries, from the design of the pack to the chemistry of the cells themselves. Comparing the Model 3’s battery pack to those found in other EVs such as the Chevrolet Bolt EV, Nissan Leaf, Jaguar I-PACE, and BMW i3, Ellis stated that Tesla’s battery pack is superior, especially with regards to the placement of battery cells in relation to the current collectors. “It’s the best design of any battery pack I’ve seen so far,” he said.
But this is not all. Ellis added that Tesla’s cylindrical cells have inherent advantages compared to the prismatic or pouch cells used by the competition. Prismatic cells, for one, expand and contract as they charge and discharge, which means that manufacturers using them have to design their battery packs with the necessary parts to handle the expansion and contraction process of the cells. These add unnecessary weight to a battery, which Tesla’s packs don’t have to deal with.
Ultimately, Ellis explained that Tesla’s battery cells simply have a higher energy density than those utilized by its competition. Tesla was able to achieve this because its batteries have superior chemistry, the consultant said. Part of the reason behind this is the fact that Tesla as a company does not really stop innovating. Tesla’s Automotive President Jerome Guillen hinted at this in a previous interview, when he said that the company’s batteries are never frozen since they are always in a state of improvement. “We are improving the design of the cell. The design of the cell is not frozen. It evolves, and we have a nice roadmap of technology improvements for the coming years,” Guillen said.
Range is something that is one of the most important factors consumers consider when purchasing an electric car. With the number of EV charging stations not yet on par with the number of gas stations on the road, it is pertinent for customers for many car buyers to acquire a vehicle that can go the distance. Tesla’s long-range vehicles, together with the company’s Supercharger Network, are a perfect fit for these types of customers.

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash
An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.
An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.
Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.
The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.

Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.
The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.
Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.
Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.

OpenAI cites distrust of SpaceX in decision to drop Cursor partnership
OpenAI will cut SpaceX-owned Cursor’s model access in November, citing Musk’s history of broken contracts.
OpenAI, the company behind ChatGPT, announced late Friday that it is ending its partnership with Cursor, cutting off the coding tool’s access to its models on November 12. The move comes two weeks after SpaceX completed its $60 billion acquisition of Cursor’s parent company, Anysphere, folding the popular AI coding assistant into Elon Musk’s growing SpaceXAI division.
In a post on its website, OpenAI said the decision came down to trust, not technology. “We cannot be confident that SpaceX will use our technology within our terms of service, based on our experience with Elon Musk’s companies violating contracts,” the company wrote. OpenAI pointed to two specific incidents: X, now part of SpaceX, allegedly breaking the terms of an existing OpenAI contract after Musk bought Twitter.
That lawsuit is the backdrop for all of this. Musk cofounded OpenAI in 2015, left the board in 2018, and sued Sam Altman and Greg Brockman in 2024, arguing they abandoned the company’s nonprofit mission for profit. A federal jury sided with OpenAI in May, finding Musk waited too long to sue rather than ruling on the merits of his claims. Musk said at the time he would appeal to the Ninth Circuit, calling the outcome a “calendar technicality” rather than a real judgment.
SpaceX’s interest in Cursor predates that verdict by weeks. The company first struck a deal with Cursor in April, securing an option to acquire it for $60 billion or pay $10 billion for joint development work instead. As Teslarati reported at the time, the logic was straightforward: Cursor was paying retail prices to Anthropic and OpenAI, two of its most direct competitors, every time a developer used its product, while SpaceX had idle capacity on its Colossus supercomputer, roughly the equivalent of a million Nvidia H100 GPUs, that Cursor could use to train its own models instead. SpaceX exercised the option in June, days after its own IPO, and the deal closed in mid-August.
Once it closed, Musk moved fast. On an all-hands call with more than 1,000 Cursor employees, he reportedly told staff that SpaceXAI’s Grok was playing catchup in the AI race, unlike Tesla and SpaceX in their own markets, and singled out Anthropic as the company to catch. Cursor CEO Michael Truell now reports directly to Musk inside SpaceXAI.
Losing OpenAI’s models leaves Cursor leaning harder on Anthropic’s Claude, which has its own compute agreement with SpaceX, and on Cursor’s in-house Composer model, the one SpaceX’s compute was supposed to accelerate in the first place. OpenAI framed the November deadline as maximum notice under its contract, and said it wants to “go above and beyond” to help developers through the transition. Whether Anthropic makes the same call is now the open question in AI coding.
