Tesla Racing Series: Types of Racing
There are many different types of racing, and while it’s impractical to cover all of them, we’ll cover a few that we tried in our 48 Tesla Model S.
Autocross
Due to its heavy weight, the Model S does not perform very well in autocross events. To clarify, since the term “Autocross” can refer to several different types of setups, here we refer to a course laid out by cones on an asphalt surface, most often done on speedway infields or large stadium parking lots. Typical speeds on this type of layout are approximately 30 mph with occasional bursts of up to 60mph.
Autocross can also refer to country road racing – a type of racing that should never be done in the Model S in order to avoid damage to the battery pack that’s mounted beneath the vehicle. While a 1/4″ thick aluminum plate protects the battery, driving on rough surfaces increases the probability of hazardous debris or other large foreign objects to strike and damage the battery.
Autocross courses are usually 1/2 to 3/4 miles in length and comprised of 30+ turns. Mainly light and small cars such as the Mazda Miata tend to dominate these type of events. Bigger and heavier cars like the Tesla Model S have much more body momentum making it more difficult to control and less nimble (the Tesla roadster would probably do a lot better here).
We think Autocross events are great when it comes to getting your feet wet in racing. There are a variety of setups that one can practice on, such as off-camber turns, turns with elevation changes, slaloms, etc. It’s also the safest possible setup, as even the worst mistake would only lead to hitting a cone. One also has the freedom to experiment with new techniques on an autocross that may not be considered safe on other types of tracks.
Open Track Racing
Open track racing, also called track days or simply tracking, is by far the most fun and entertaining type of racing. This type of racing allows you to race alongside other cars on racetracks of varying sizes and complexities. Courses can range from lower speed technical road courses to as large as full stadium ovals where NASCAR races are held.
It’s important to note that this type of open track racing should not be confused with wheel-to-wheel competition racing, where the driver needs to be licensed, the car has to be race prepared, and the objective is to win by any means necessary – even if it means wrecking the vehicle. The objective of open track racing is to have fun, be competitive but courteous, and more importantly walk away with your car undamaged.
The Tesla Model S does well on these tracks given its sports car like handling, excellent stability controls, and snappy acceleration. One of the most exhilarating aspects of open track racing is being able to drive and pass other contenders at speeds well over 100 mph, and in a environment that’s generally safer than competition wheel-to-wheel racing.
At the same time, the tracks have a reasonable number of turns where you can practice your driving skills, such as following racing lines, braking zones, track outs, on and off camber turns, etc. While its fairly straightforward on paper, doing it in real life is a lot more difficult. It’s a very rewarding experience when you master a segment and can repeat it time after time. While open track racing is not a competition for track position, you are in fact competing with other cars for the best overall lap time.
Everyone we’ve ever interacted with at these events were friendly, helpful, and professional. And while you don’t receive a prize for crossing the line first, as you do in competition racing, the real reward is being able to meet a group of passionate people that all have the common goal of just plain ol’ having fun!
And this is where the primary focus of TESLARATI 48 Tesla is. At the time of writing, we completed 4 track events, Willow Springs (The Big Willow), the Streets of Willow, the California Speedway (Fontana Auto Club Speedway), and Buttonwillow.
After starting in the Novice group at the first track, we were promoted to the Intermediate group at the second event based on fast lap times. The 48 Tesla completed fastest lap times in the Intermediate groups around the middle of the pack in all subsequent events. Working on our skills while in this group will also give us time to seek alternatives to improve cooling of the Tesla drivetrain components that can cause power limitations. We’re also really looking forward to these new tracks coming up in the first half of the year: Chuckwalla, Spring Mountain, Sonoma, Thunderhill, and Laguna Seca.
We’ll be publishing our full event schedule as it becomes available so stay tuned!

Elon Musk drops a surprise update on Boring Company’s next big dig
Musk says Boring Company could shrink the Austin to San Antonio drive to just minutes.
Elon Musk says The Boring Company is working on what he called “a simple, precursor Hyperloop” tunnel connecting Austin and San Antonio, targeting speeds above 200 mph and cutting a drive that can take up to two and a half hours down to a consistent under 30 minutes. Musk posted the idea on X Sunday, in a reply to a repost of an AI generated video imagining a science fiction future with human colonies on other worlds, which he shared with the line “This is the future we shall bring into being.”

The Boring Company’s own account picked up the idea in the same thread, adding a detail about how the trip would actually work: “Because Loop/Hyperloop is express (i.e. no intermediate stops), one could travel from an Austin parking lot to a favorite San Antonio restaurant in about 30 minutes. As long as they both have Loop stations.” That framing ties the proposed intercity link to the same station model the company already runs in Las Vegas, where riders enter the tunnel network through small, garage style stops rather than one central terminal.
This is not the company’s first run at the Austin to San Antonio corridor. Boring Company floated tunnels between the two cities as far back as 2021, and later competed for a separate San Antonio Loop project tied to the airport before that specific bid stalled. Pitches for tunnels in Chicago, Los Angeles, and a New York to Washington corridor have followed a similar pattern of big announcement without a shovel in the ground.
What is different this time is the balance sheet, especially since The Boring Company closed a 3 billion dollar funding round led by investors in the United Arab Emirates earlier this month at a valuation near 23 billion dollars, giving the tunneling company more capital to chase speculative projects than it had during its earlier Texas pitches. The company is also mid-build on two other intercity systems it has actually broken ground on, inc;luding a Nashville tunnel linking downtown to the airport, where a second boring machine finished commissioning in June, and its Las Vegas network, where the station count keeps climbing on paper faster than tunnels get dug.
That gap between announcement and execution is the reason to treat Sunday’s post as an opening bid rather than a project. A tunnel spanning roughly 80 miles between two metro areas, running at speeds Boring Company has not demonstrated over any real distance, would dwarf anything the company has built. For now, the Austin to San Antonio Hyperloop exists as a caption under an AI generated space video.

Tesla eyes supply partners for Optimus mass production
Tesla certified three Chinese suppliers for Optimus mass production, signaling its robot timeline is accelerating.
Tesla’s robotics team traveled to Ningbo, in China’s Zhejiang province, on September 16 and spent the following day auditing component suppliers for Optimus, according to a Bloomberg report cited by RobotAIGeek. The visit moved three manufacturers from provisional status to certified mass production partners: Tuopu Group, which handles actuators and chassis components, Ningbo Joyson Electronic, a sensor supplier, and Zhejiang Sanhua Intelligent Controls, which builds thermal management systems. All three already supply parts to Tesla’s electric vehicles, and the audit reportedly came with fresh orders that supply chain reports put at an initial batch of roughly 5,000 units.
Tuopu, Joyson, and Sanhua built their manufacturing base serving the automotive industry, where tolerances and volume requirements are already close to what a mass produced humanoid robot demands. Sanhua in particular has history here. Teslarati reported last October that the company had received a roughly $685 million order for linear actuators tied to Optimus, a volume industry watchers estimated could cover around 180,000 robots once production ramped.
Supply chain reports tied to this week’s audit put Tesla’s near term production goal at about 1,000 Optimus units a week by late September, rising to 2,000 to 2,500 units a week by the end of the year. That pace would put real weight behind the timeline Tesla has been building toward since May, when it wound down Model S and Model X production at Fremont to convert that floor space into a dedicated Optimus line targeting one million units annually. JPMorgan analysts who toured the factory in August confirmed the conversion took roughly four months, a pace Musk has called unprecedented for a facility that size.
New drone video shows Tesla’s Optimus Factory reaching a turning point
Fremont is only the first phase. A second, larger Optimus plant is rising at Gigafactory Texas, where drone footage shared by Joe Tegtmeyer last week showed the structural steel nearing completion on the north end of the building. Tesla has said that facility is meant to eventually support production of up to 10 million units a year, though volume output there is not expected before 2027.
Commercial sales of Optimus are still targeted for the second half of 2027, but production is expected to start well before then. JPMorgan analyst Rajat Gupta has said Tesla’s “Optimus Academy” program, which uses early units to collect real world training data inside Tesla’s own facilities, is expected to be running later this year. Bloomberg Intelligence analyst Ian Ma described the Ningbo audits as “a positive commercialization signal for China’s humanoid supply chain,” noting that sentiment could improve further if the visit leads to confirmed supplier nominations and larger orders. The Solactive China Humanoid Robotics Index rose about 1.4% on the news, though it remains down roughly 30% for the year.

Tesla primes Cybercabs for 4K streaming and high bandwidth gaming with Starlink integration
Tesla is now shipping Cybercabs from Giga Texas with Starlink hardware built in as standard.
Tesla’s Cybercabs are now leaving Gigafactory Texas with Starlink hardware on the rear hatch in significant numbers, according to drone footage captured Tuesday by longtime Austin drone observer Joe Tegtmeyer. Production at the factory ramped back up after the Labor Day weekend, and his flyover of the outbound lot showed rows of gold Cybercabs alongside Model Y Long Wheelbase units, many carrying the satellite module for the first time as standard equipment rather than a one off retrofit.
Giga Texas today is busy with production coming back up following the long weekend. Of interest today in the outbound lot is the appearance of hundreds of Mode; YL’s and many more Cybercabs and for the 1st time equipped with the Starlink module one the hatch in big numbers.

Tesla first showed Starlink built into an actual Cybercab on August 10, when the Robotaxi account posted images of a single gold unit with the antenna integrated into the roofline above the taillights and called it the first Cybercab with Starlink integration. That followed a July reveal where Tesla and Starlink jointly posted a cutaway diagram of the antenna placement without a working vehicle to back it up. Ashok Elluswamy, Tesla’s VP of AI software, said at the time that the connection isn’t required for the car to drive itself. It exists mainly for navigation, customer service and keeping tabs on the fleet.
Musk has made a different case in public. During Tesla’s Q2 earnings call, he said the company can’t afford robotaxis stranded in what he called “Bermuda Triangles of lack of cellular connectivity,” and he separately claimed on X that Starlink will eventually reach every Tesla built, calling it the only way to deliver high bandwidth to billions of vehicles. He has also pitched the antenna as an entertainment upgrade, telling riders they would be able to stream 4K video or play games during a trip.
The rollout has moved fast since. Robotaxi service opened to the public in Austin on September 3, and Cybercabs had already been spotted with Starlink hardware in Houston and near Miami International Airport in the weeks before Tuesday’s factory footage showed the module shipping at volume rather than on scattered test units. Whether the satellite link earns its keep is still an open question. Tesla’s unsupervised service currently runs in dense metro geofences in Texas and Florida, markets where cellular coverage is already strong, which is not where the rural dead zones Musk describes tend to show up.
