Tesla Top 5 Week in Review: Competition, Power, and Model 3 Stir the Tesla Brand
This week in the news, we examined the claim that the Dodge Demon may surpass the Tesla Model S P100D as the world’s fastest 0-60 production car. The Model S also was featured for its resale value, as a new survey indicates that the Model S has a much higher second owner value than originally thought. The Tesla board of directors composition may change, if pressure from an investor group led by the California State Teachers’ Retirement System has anything to do with it. Lithium-ion battery technology made the headlines, with Panasonic envisioning improvements that may translate into longer range and increased safety. Finally, information about the final unveiling event of the Tesla Model 3 made potential buyers happy. Here are those stories and more in this week’s edition of the Teslarati week in review.
Dodge “Demon” looks to dethrone Tesla’s title for “quickest production car” in the world
The Challenger SRT Demon will enter the automotive market with 840 horsepower and 770 pound-feet of torque, according to sources inside Fiat Chrysler automobiles. The car will reportedly be the world’s fastest 0-60 production car — in 2.3 seconds — and from 0-30 m.p.h. — 1 second. Will the Demon eclipse the Tesla Model S P100D, which Motor Trend Magazine deemed the quickest production car in the world after a 2.28 second run to 60 miles per hour? Dodge Demon testing at a sticky drag strip isn’t really comparable to the Tesla Model S P100D record that was earned on a public road, is it? Only time will tell.
Survey ranks used Tesla Model S as #1 in retained value and fastest selling among peers
Survey results released by Autolist suggest that the Model S sells an average of 5% faster than its peer group as well as fastest overall among the best selling vehicles from three companies. The Model S also soared in prices relative to listing price expectations. Some months were 5% over expectations, while the best performing Ford and GMs struggled to top 1%. Affordability for the Model S as contained within the survey results vacillated depending on region, with Maryland providing the most reasonable used Model S costs at 7.2% below the national average.
Investor group urges Tesla to seek board members independent of Elon Musk
The California State Teachers’ Retirement System has led a coalition of concerned investors in a move to pressure Tesla CEO Elon Musk to diversify the Tesla board. With the majority of Tesla board members having personal or professional ties to Musk, the suggestion is that independence or objectivity might become compromised. The managers who have expressed concern control a combined $721 billion in assets. They have also advocated for annual, rather than staggered three year director elections. “Directors should be held to a higher standard of independence given the conflicts of interest that permeate this board,” the letter to Tesla director Antonio Gracias said. “A thoroughly independent board would provide a critical check on possible dysfunctional group dynamics, such as groupthink.”
Tesla partner Panasonic says 30% energy density increase in lithium-ion batteries possible
Recent comments by Panasonic indicate that, while Lithium-ion batteries (LIBs) represent revolutionary technology when applied to today’s electric vehicles, future progress must continue. LIBs at the present are near to a theoretical maximum energy density. Because drivers are demanding longer ranges and quicker charging times, more R&D is needed to improve the current state of LIB technology. “We think the existing technology can still extend the energy density of LIBs by 20% to 30%,” Panasonic’s President Kazuhiro Tsuga said. “But there is a trade-off between energy density and safety. So, if you look for even more density, you have to think about additional safety technology as well. Solid-state batteries are one [possible] answer.”
Tesla Model 3 final unveiling event will take place in July
Tesla CEO Elon Musk announced that the Tesla Model 3 will have a third reveal in July, 2017 in anticipation of initial deliveries late this year. The July event will give potential buyers the opportunity to see the Model 3 up in real configurations; the April, 2016 first unveiling didn’t permit media photographs. With many sightings of the Model 3 in and around the Palo Alto company headquarters, the anticipation around the Model 3 is at an all-time high. One aspect of the Model 3 that has everyone buzzing is Musk’s statement that the “real steering controls and system” for the Model 3 feel “like a spaceship.” We can’t wait to see for ourselves! Eventual production plans are to incrementally increase Model 3 production in 2018 with eventual annual production of 500,00 units.

Tesla Lathrop Megafactory celebrates massive Megapack battery milestone
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments.

The Tesla Lathrop Megafactory recently achieved a new milestone. As per the official Tesla Megapack account on X, the Lathrop Megafactory has produced its 15,000th Megapack 2 XL battery.
15,000 Megapack Batteries
Tesla celebrated the milestone with a photo of the Lathrop Megafactory team posing with a freshly produced Megapack battery. To commemorate the event, the team held balloons that spelled out “15,000” as they posed for the photo.
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments. Designed for grid-scale applications, each Megapack offers 3.9 MWh of energy and 1.9 MW of power. The battery is extremely scalable, making it perfect for massive energy storage projects.
More Megafactories
The Lathrop Megafactory is Tesla’s first dedicated facility for its flagship battery storage system. It currently stands as the largest utility-scale battery factory in North America. The facility is capable of producing 10,000 Megapack batteries every year, equal to 40 GWh of clean energy storage.
Thanks to the success of the Megapack, Tesla has expanded its energy business by building and launching the Shanghai Megafactory, which is also expected to produce 40 GWh of energy storage per year. The ramp of the Shanghai Megafactory is quite impressive, with Tesla noting in its Q1 2025 Update Letter that the Shanghai Megafactory managed to produce over 100 Megapack batteries in the first quarter alone.
Tesla Energy’s Potential
During the first quarter earnings call, CEO Elon Musk stated that the Megapack is extremely valuable to the energy industry.
“The Megapack enables utility companies to output far more total energy than would otherwise be the case… This is a massive unlock on total energy output of any given grid over the course of a year. And utility companies are beginning to realize this and are buying in our Megapacks at scale,” Musk said.

Tesla Megapacks powers the xAI Colossus supercomputer
Tesla Megapacks step in to stabilize xAI’s Colossus supercomputer, replacing natural gas turbines. Musk’s ventures keep intertwining.

Tesla Megapack batteries will power the xAI Colossus supercomputer in Memphis to ensure power stability. The collaboration between Tesla and xAI highlights the synergy among Elon Musk’s ventures.
The artificial intelligence startup has integrated Tesla Megapacks to manage outages and demand surges, bolstering the facility’s reliability. The Greater Memphis Chamber announced that Colossus, recently connected to a new 150-megawatt electric substation, is completing its first construction phase. This transition addresses criticism from environmental justice groups over the initial use of natural gas turbines.
“The temporary natural gas turbines that were being used to power the Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months.
“About half of the operating turbines will remain operating to power Phase II GPUs of xAI until a second substation (#22) already in construction is completed and connected to the electric grid, which is planned for the Fall of 2025, at which time the remaining turbines will be relegated to a backup power role,” the Chamber stated.
xAI’s rapid development of Colossus reflects its ambition to advance AI capabilities, but the project has faced scrutiny for environmental impacts. The shift to Megapacks and grid power aims to mitigate these concerns while ensuring operational continuity.
The Megapack deployment underscores the collaboration among Musk’s companies, including Tesla, SpaceX, Neuralink, and The Boring Company. Tesla appears to be the common link between all of Musk’s companies. For example, The Boring Company built a tunnel in Giga, Texas. In addition, Musk has hinted at a potential collaboration between the Tesla Optimus Bot and Neuralink. And from January 2024 to February 2025, xAI invested $230 million in Megapacks, per a Tesla filing.
Tesla Energy reported a 156% year-over-year increase in Q1 2025, deploying 10.4 GWh of storage products, including Megapacks and Powerwalls. Tesla’s plans for a new Megapack factory in Waller County, Texas, which is expected to create 1,500 jobs in the area, further signal its commitment to scaling energy solutions.
As xAI leverages Tesla’s Megapacks to power Colossus, the integration showcases Musk’s interconnected business ecosystem. The supercomputer’s enhanced stability positions xAI to drive AI innovation, while Tesla’s energy solutions gain prominence, setting the stage for broader technological and economic impacts.

Tesla Energy celebrates one decade of sustainability
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.

Tesla Energy recently celebrated its 10th anniversary with a dedicated video showcasing several of its milestones over the past decade.
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.
Tesla Energy Early Days
When Elon Musk launched Tesla Energy in 2015, he noted that the business is a fundamental transformation of how the world works. To start, Tesla Energy offered the Powerwall, a 7 kWh/10 kWh home battery system, and the Powerpack, a grid-capable 100 kWh battery block that is designed for scalability. A few days after the products’ launch, Musk noted that Tesla had received 38,000 reservations for the Powerwall and 2,500 reservations for the Powerpack.
Tesla Energy’s beginnings would herald its quiet growth, with the company later announcing products like the Solar Roof tile, which is yet to be ramped, and the successor to the Powerwall, the 13.5 kWh Powerwall 2. In recent years, Tesla Energy also launched its Powerwall 3 home battery and the massive Megapack, a 3.9 MWh monster of a battery unit that has become the backbone for energy storage systems across the globe.
Key Milestones
As noted by Tesla Energy in its recent video, it has now established facilities that allow the company to manufacture 20,000 units of the Megapack every year, which should help grow the 23 GWh worth of Megapacks that have already been deployed globally.
The Powerwall remains a desirable home battery as well, with more than 850,000 units installed worldwide. These translate to 12 GWh of residential entry storage delivered to date. Just like the Megapack, Tesla is also ramping its production of the Powerwall, allowing the division to grow even more.
Tesla Energy’s Role
While Tesla Energy does not catch as much headlines as the company’s electric vehicle businesses, its contributions to the company’s bottom line have been growing. In the first quarter of 2025 alone, Tesla Energy deployed 10.4 GWh of energy storage products. Powerwall deployments also crossed 1 GWh in one quarter for the first time. As per Tesla in its Q1 2025 Update Letter, the gross margin for the Energy division has improved sequentially as well.
