Tesla and Jeff Dahn once teased the development of a battery cell that would last one million miles. For years, Tesla fans, enthusiasts, and those interested in battery technology were heavily invested in Dahn’s research, which led to the idea that the batteries in electric vehicles would outlast the vehicles themselves.

Dahn’s office at Dalhousie University features a lineup of heavy-hitting scientists and engineers who have all worked cohesively with Tesla and its research chair Chongyin Yang.

One of them is Michael Metzger, who has been with Dahn’s lab at Dalhousie since January 2021, when Tesla and the battery research facility renewed their partnership.

Over the years of the Tesla-Dahn partnership, the automaker, as well as the team of engineers, have developed strategies to promote battery longevity. Various patents, like an electrolyte solvent and new revolutionary electrode designs, were geared toward helping battery cells reach thousands of life cycles, enabling one million miles of operation.

In a recent interview with Electric Autonomy, Metzger detailed the various developments that have come from working with Tesla over the past several years. One of the things Metzger shared was the various battery cell designs that the Dalhousie battery team has engineered for Tesla.

Among the designs and chemistries, LFP (lithium iron phosphate) and NMC (nickel manganese cobalt) are two that were discussed during the interview. While LFP is considered second-best, NMC has taken the top spot, according to Metzger.

Initially, it was capable of thousands of cycles, but it now has the capacity to run 19,500 cycles and counting.

“Each cycle is 300 kilometers. So, if it were at 20,000 cycles, it would be 6 million kilometers,” Metzger said in the interview.

6 million kilometers is equal to 3,728,227 miles. The technology has nearly quadrupled in the past few years.

Dahn said in an interview with the Nickel Institute earlier this year that the team had developed and demonstrated batteries that were capable of these massive numbers.

We may be some years away from these batteries being put into a consumer setting. Additionally, NMC batteries feature cobalt, a controversial material that has proven benefits in terms of cell cycle stability.

Automakers are opting for LFP cells in their lower-range vehicles. Tesla transitioned to these packs in Standard Range EVs in 2021.

NASA and SpaceX are targeting July 31 for the launch of Crew-11, the next crewed mission to the International Space Station (ISS). The flight will lift off from Launch Complex 39A at Kennedy Space Center in Florida, using the Crew Dragon Endeavour and a Falcon 9 booster.

Crew Dragon Endeavour returns

Crew-11 will be the sixth flight for Endeavour, making it SpaceX’s most experienced crew vehicle to date. According to SpaceX’s director of Dragon mission management, Sarah Walker, Endeavour has already carried 18 astronauts representing eight countries since its first mission with NASA’s Bob Behnken and Doug Hurley in 2020, as noted in an MSN report.

“This Dragon spacecraft has successfully flown 18 crew members representing eight countries to space already, starting with (NASA astronauts) Bob (Behnken) and Doug (Hurley) in 2020, when it returned human spaceflight capabilities to the United States for the first time since the shuttle retired in July of 2011,” Walker said.

For this mission, Endeavour will debut SpaceX’s upgraded drogue 3.1 parachutes, designed to further enhance reentry safety. The parachutes are part of SpaceX’s ongoing improvements to its human-rated spacecraft, and Crew-11 will serve as their first operational test.

The Falcon 9 booster supporting this launch is core B1094, which has launched in two previous Starlink missions, as well as the private Ax-4 mission on June 25, as noted in a Space.com report.

The four-members of Crew-11 are NASA astronauts Zena Cardman and Mike Fincke, as well as Japan’s Kimiya Yui and Russia’s Oleg Platonov.

Tight launch timing

Crew-11 is slated to arrive at the ISS just as NASA coordinates a sequence of missions, including the departure of Crew-10 and the arrival of SpaceX’s CRS-33 mission. NASA’s Bill Spetch emphasized the need for careful planning amid limited launch resources, noting the importance of maintaining station altitude and resupply cadence.

“Providing multiple methods for us to maintain the station altitude is critically important as we continue to operate and get the most use out of our limited launch resources that we do have. We’re really looking forward to demonstrating that capability with (CRS-33) showing up after we get through the Crew-11 and Crew-10 handover,” Spetch stated.

EV fans urge Tesla to acquire Unplugged Performance for edge in fleet and security industry

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles.

A growing number of Tesla enthusiasts and longtime community voices are calling on the electric vehicle maker to acquire Unplugged Performance, a California-based aftermarket company best known for tuning Tesla vehicles and developing specialized government fleet solutions under its UP.FIT division.

The idea was once considered a niche proposal among EV fans, but it is now gaining serious attention not just as a performance play but as a strategic move to deepen Tesla’s roots in the fleet and security industry. 

A strategic fit

Unplugged Performance has built a name for itself by producing performance upgrades for Tesla vehicles, from track-optimized components to visual and aerodynamic upgrades. But in recent years, its UP.FIT division has pivoted toward a more functional future by outfitting Tesla vehicles like Model Ys for police, military, and government use.

That work has sparked growing calls for closer collaboration with Tesla, especially as the EV maker increasingly leans into autonomy, AI, and fleet services as core components of its next chapter.

“I posted this four years ago, but I think it’s more true now than ever,” wrote Whole Mars Catalog, a well-known Tesla investor and FSD Beta tester, on X. “Tesla should buy Unplugged. But not just as a Performance division. What they are doing with UP.FIT unlocks large government and commercial fleet purchases that can improve utilization.”

Tesla fans such as shareholder Sawyer Merritt echoed the sentiment, calling Unplugged a “great fit within Tesla.” adding, “They are literally located directly next to Tesla’s design studio in Hawthorne.”

Enabling the next wave

Supporters of the idea noted that integrating Unplugged into Tesla’s corporate structure could help accelerate the adoption of autonomous technologies in government sectors. With UP.FIT patrol cars already in use across some U.S. police departments, Tesla fans envisioned a future where self-driving Teslas could potentially revolutionize law enforcement, search-and-rescue, and public service logistics.

“Just imagine how autonomous patrol cars could transform policing and bring us into a safer future,” the veteran FSD tester wrote.

The benefits could also extend to Tesla’s existing consumer base. “They also have some incredible products in the works that I think will appeal to many ordinary Tesla drivers — not just those looking for performance or mods. Stuff that’s so good it should have come straight from the design studio next door,” Whole Mars Catalog noted.

Unplugged Performance, founded in 2013, shares not just a product vision with Tesla, but also geography. Its Hawthorne headquarters sits directly adjacent to Tesla’s design studio, and the two companies have maintained a close working relationship over the years. The aftermarket firm has long positioned itself as a “mission-aligned” partner to Tesla.

Tesla has begun rolling out Grok, an in-car conversational AI assistant developed by xAI, to eligible vehicles starting July 12. The feature marks the most direct integration yet between Elon Musk’s artificial intelligence startup and Tesla’s consumer product lineup, offering drivers hands-free access to a chat-style companion while on the road.

Grok comes pre-installed on new vehicles

According to Tesla’s FAQ page for the feature, all new vehicles delivered on or after July 12, 2025, will include Grok AI out of the box. Owners of older vehicles may gain access through an over-the-air update, provided their vehicle meets a few hardware and software requirements.

Specifically, Grok is currently only supported on Tesla models equipped with an AMD infotainment processor and running vehicle software version 2025.26 and higher. Compatible models include the Model S, Model 3, Model X, Model Y, and Cybertruck. A Premium Connectivity subscription or active Wi-Fi connection is also required.

Tesla notes that additional vehicle compatibility may arrive in future software updates.

Grok’s features and limitations for now

Drivers can engage with Grok using the App Launcher or by pressing and holding the voice command button on the steering wheel. Grok is designed to answer questions and hold conversations using natural language, offering responses tailored to its chosen personality—ranging from “Storyteller” to the more eccentric “Unhinged.”

For fun, Tesla posted a demonstration of Grok likely running on “Unhinged” talking about what it would do to Optimus when they are on a date, much to the shock of the humanoid robot’s official social media account.

It should be noted, however, that Grok cannot currently issue commands to the vehicle itself, at least for now. Traditional voice commands for tasks like climate control, navigation, or media remain separate from Grok as of writing.

The feature is being released in Beta and does not require a Grok account or xAI subscription to activate, although that policy may change over time.

Grok privacy and in-car experience

Tesla emphasizes that interactions with Grok are securely processed by xAI and not linked to a user’s Tesla account or vehicle. Conversations remain anonymous unless a user signs into Grok separately to sync their history across devices.

Tesla has also begun promoting Grok directly on its official vehicle webpages, showcasing the feature as part of its in-car experience, further highlighting the company’s increasing focus on AI and infotainment features on its all-electric vehicles.
