Tesla’s Battery Day is only a few days away, and as the event draws closer, it appears that the electric car maker is starting to make its “Roadrunner” site as presentable as possible to its visitors. As could be seen in a recent drone flyover of the pilot battery cell production site, the surroundings of the Kato Road building are now being cleared of materials and equipment, likely in preparation for Battery Day.
The Kato Road facility holds one of the most highly-anticipated segments of the upcoming Battery Day event. During the event, Tesla is expected to discuss the work that it has been doing with its battery tech over the years. Much of these developments have been heavily speculated, with reports indicating that Tesla will be discussing the development and capabilities of its next-generation cells, which could last a million miles on the road or decades if used as energy storage units.
But beyond these discussions, Battery Day will also involve a tour of Tesla’s “Roadrunner” site, which is located in Kato Road, close to the Fremont factory. The full details of the “Roadrunner” site have not been discussed by Tesla so far, though reports and filings about the site have suggested that the location holds the pilot production line for the electric car maker’s own custom-designed cells.
Interestingly enough, a recent leak reported in EV publication Electrek hinted at what the “Roadrunner” battery cells could possibly look like. Images leaked to the publication featured a rather hefty cell that is far larger than the 18650 and 2170 batteries being used by Tesla in its existing electric vehicle lineup. Observations and basic analyses from Tesla community members with a background in battery technology have pointed to the “Roadrunner” cell potentially adopting a 54×98 form factor.
If these speculations are accurate, Tesla may be going for complete EV domination with its next-generation batteries. Battery cells that adopt the 54×98 form factor hold about 10 times the volume of a 2170 cell, and according to Jordan Giesige of The Limiting Factor channel on YouTube, this presents several advantages for the electric car maker. With the larger cells, for example, Tesla could equip its vehicles with an order of magnitude fewer cells than before, resulting in massive savings in production costs.
These speculations will likely be proven or debunked this coming Battery Day, which is scheduled for this coming Tuesday, September 22, 2020. Regardless of this, however, the Kato Road facility is poised to get even busier in the near future. As noted in filings to the City of Fremont, the “Roadrunner” site will be housing 45 research and development employees and up to 425 manufacturing workers that are spread through several shifts from Monday to Friday. This should make the “Roadrunner” facility humming along nicely, and perhaps even producing enough cells for low-volume vehicles like the Plaid Model S, Plaid Model X, and the next-generation Roadster.

Tesla Supercharger Diner food menu gets a sneak peek as construction closes out
What are you ordering at the Tesla Diner?

The Tesla Supercharger Diner in Los Angeles is nearing completion as construction appears to be winding down significantly. However, the more minor details, such as what the company will serve at its 50s-style diner for food, are starting to be revealed.
Tesla’s Supercharger Diner is set to open soon, seven years after CEO Elon Musk first drafted the idea in a post on X in 2018. Musk has largely come through on most of what he envisioned for the project: the diner, the massive movie screens, and the intended vibe are all present, thanks to the aerial and ground footage shared on social media.
We already know the Diner will be open 24/7, based on decals placed on the front door of the restaurant that were shared earlier this week. We assume that Tesla Optimus will come into play for these long and uninterrupted hours.
The Tesla Diner is basically finished—here’s what it looks like
As far as the food, Tesla does have an email also printed on the front door of the Diner, but we did not receive any response back (yet) about what cuisine it will be offering. We figured it would be nothing fancy and it would be typical diner staples: burgers, fries, wings, milkshakes, etc.
According to pictures taken by @Tesla_lighting_, which were shared by Not a Tesla App, the food will be just that: quick and affordable meals that diners do well. It’s nothing crazy, just typical staples you’d find at any diner, just with a Tesla twist:
Tesla Diner food:
• Burgers
• Fries
• Chicken Wings
• Hot Dogs
• Hand-spun milkshakes
• And more https://t.co/kzFf20YZQq pic.twitter.com/aRv02TzouY— Sawyer Merritt (@SawyerMerritt) July 17, 2025
As the food menu is finalized, we will be sure to share any details Tesla provides, including a full list of what will be served and its prices.
Additionally, the entire property appears to be nearing its final construction stages, and it seems it may even be nearing completion. The movie screens are already up and showing videos of things like SpaceX launches.
There are many cars already using the Superchargers at the restaurant, and employees inside the facility look to be putting the finishing touches on the interior.

It’s almost reminiscent of a Tesla version of a Buc-ee’s, a southern staple convenience store that offers much more than a traditional gas station. Of course, Tesla’s version is futuristic and more catered to the company’s image, but the idea is the same.
It’s a one-stop shop for anything you’d need to recharge as a Tesla owner. Los Angeles building permits have not yet revealed the date for the restaurant’s initial operation, but Tesla may have its eye on a target date that will likely be announced during next week’s Earnings Call.

Tesla’s longer Model Y did not scale back requests for this vehicle type from fans
Tesla fans are happy with the new Model Y, but they’re still vocal about the need for something else.

Tesla launched a slightly longer version of the Model Y all-electric crossover in China, and with it being extremely likely that the vehicle will make its way to other markets, including the United States, fans are still looking for something more.
The new Model Y L in China boasts a slightly larger wheelbase than its original version, giving slightly more interior room with a sixth seat, thanks to a third row.
Tesla exec hints at useful and potentially killer Model Y L feature
Tesla has said throughout the past year that it would focus on developing its affordable, compact models, which were set to begin production in the first half of the year. The company has not indicated whether it met that timeline or not, but many are hoping to see unveilings of those designs potentially during the Q3 earnings call.
However, the modifications to the Model Y, which have not yet been officially announced for any markets outside of China, still don’t seem to be what owners and fans are looking forward to. Instead, they are hoping for something larger.
A few months ago, I reported on the overall consensus within the Tesla community that the company needs a full-size SUV, minivan, or even a cargo van that would be ideal for camping or business use.
Tesla is missing one type of vehicle in its lineup and fans want it fast
That mentality still seems very present amongst fans and owners, who state that a full-size SUV with enough seating for a larger family, more capability in terms of cargo space for camping or business operation, and something to compete with gas cars like the Chevrolet Tahoe, Ford Expedition, or electric ones like the Volkswagen ID.BUZZ.
We asked the question on X, and Tesla fans were nearly unanimously in support of a larger SUV or minivan-type vehicle for the company’s lineup:
🚨 More and more people are *still* saying that, despite this new, longer Model Y, Tesla still needs a true three-row SUV
Do you agree? https://t.co/QmbRDcCE08 pic.twitter.com/p6m5zB4sDZ
— TESLARATI (@Teslarati) July 16, 2025
Here’s what some of the respondents said:
100% agree, we need a larger vehicle.
Our model Y is quickly getting too small for our family of 5 as the kids grow. A slightly longer Y with an extra seat is nice but it’s not enough if you’re looking to take it on road trips/vacations/ kids sports gear etc.
Unfortunately we…

Tesla is certainly aware that many of its owners would like the company to develop something larger that competes with the large SUVs on the market.
However, it has not stated that anything like that is in the current plans for future vehicles, as it has made a concerted effort to develop Robotaxi alongside the affordable, compact models that it claims are in development.
It has already unveiled the Robovan, a people-mover that can seat up to 20 passengers in a lounge-like interior.
The Robovan will be completely driverless, so it’s unlikely we will see it before the release of a fully autonomous Full Self-Driving suite from Tesla.

Tesla launches first Virtual Power Plant in UK – get paid to use solar
Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom.

Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom. This feature enables users of solar panels and energy storage systems to sell their excess energy back to the grid.
Tesla is utilizing Octopus Energy, a British renewable energy company that operates in multiple markets, including the UK, France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States, as the provider for the VPP launch in the region.
The company states that those who enroll in the program can earn up to £300 per month.
Tesla has operated several VPP programs worldwide, most notably in California, Texas, Connecticut, and the U.S. territory of Puerto Rico. This is not the first time Tesla has operated a VPP outside the United States, as there are programs in Australia, Japan, and New Zealand.
This is its first in the UK:
Our first VPP in the UK
You can get paid to share your energy – store excess energy in your Powerwall & sell it back to the grid
You’re making £££ and the community is powered by clean energy
Win-win pic.twitter.com/evhMtJpgy1
— Tesla UK (@tesla_uk) July 17, 2025
Tesla is not the only company that is working with Octopus Energy in the UK for the VPP, as it joins SolarEdge, GivEnergy, and Enphase as other companies that utilize the Octopus platform for their project operations.
It has been six years since Tesla launched its first VPP, as it started its first in Australia back in 2019. In 2024, Tesla paid out over $10 million to those participating in the program.
Participating in the VPP program that Tesla offers not only provides enrolled individuals with the opportunity to earn money, but it also contributes to grid stabilization by supporting local energy grids.
