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 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.

Published

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.

Elon Musk breaks silence on OpenAI trial decision

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.

Elon Musk admits he was ‘clearly wrong’ about Anthropic

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.

Tesla Robotaxi gets a massive upgrade in Nevada

Nevada regulators just approved a massive expansion of Tesla’s robotaxi fleet across the entire county.

Tesla’s robotaxi footprint in Nevada just grew by roughly 500 times in a single regulatory vote.

The Nevada Transportation Authority approved Tesla’s full Autonomous Vehicle Network Company permit on Thursday, clearing the way for the company to deploy up to 5,000 driverless vehicles across Clark County over the next 12 months. The decision came during a four hour general session meeting that Tesla investor Sawyer Merritt watched live and reported on X, noting the vote replaces the interim order that had limited Tesla to just 10 robotaxis on a narrow stretch of the Las Vegas Strip.

That earlier cap, covered here after it surfaced on August 13, came with restrictions that looked stricter than what Tesla runs in Austin: a 45 mph speed ceiling, no airport pickups, and a geofence confined to the Strip corridor. The new approval extends Tesla’s operating authority to all of Clark County, with room to request an even wider geofence across the state.

Tesla representatives at the meeting said they have no intention of putting 5,000 cars on the road right away. Commercial rides are expected to start within 30 days, pending vehicle inspections, insurance filings, and fare approval, the standard steps every robotaxi operator in Nevada has had to clear.

Tesla’s own Robotaxi account replied to the news with a short line, The golden future is upon us.

The timing lines up with Tesla’s broader robotaxi push this month. The company is preparing to open Cybercab rides to the public in Austin as soon as this month, and it opened a sweepstakes for riders to win a seat at the launch event. Tesla filed its original application for a 5,000 vehicle Nevada fleet back in June, a request regulators trimmed to 10 vehicles when they issued the interim order in July. Thursday’s vote effectively grants the number Tesla asked for from the start.

Zoox, the Amazon owned robotaxi operator, has run in Nevada since 2025 and was capped at 100 vehicles before Thursday’s decision. Tesla’s new ceiling puts it well ahead of that comparison on paper, though the company has said its actual fleet size will depend on how quickly FSD v15 rolls out, the software update executives have called the gateway to scaling unsupervised robotaxi operations nationwide.
