Watch this Tesla Model S conquer Autocross [Video]
The following post was originally published on EVANNEX
Grant M. is like a superhero with a secret identity – during the week, he works as a lawyer, but on the weekends, he takes his Tesla S60 to the autocross track to do battle with the forces of fossil fuel.
Autocross, also called solo or (in Canada) autoslalom, is a timed competition in which drivers navigate a course that includes straightaways, curves and slaloms. It’s less about fast acceleration and high speed than about handling and precision driving. The autocross community is egalitarian – any kind of car can compete, and drivers of all skill levels are welcome. Courses are usually temporary, set up with cones on a speedway parking lot or a disused airstrip – this prevents experienced drivers from gaining an advantage, as the course may be different every time.
According to the Sports Car Club of America, most autocross courses are designed so that the cars won’t exceed normal highway speeds – around 55-60 mph. However, “that doesn’t mean they are slow. Well-designed courses will feel plenty fast as you attempt to maintain that speed through a series of elements. Imagine slaloming every barrel in a 55-mph construction zone, and you will start to get the idea.” As the New Brunswick Sporting Car Club puts it, “While AutoSlalom events typically involve lower speeds than other motorsports, the number of driver inputs per second is comparable to Formula One.”
Driving an electric vehicle (EV) on the autocross track is very different from driving a gas-burner. The EV’s instant acceleration gives it an advantage coming out of corners onto a straightaway. However there’s also a drawback: EVs, especially the Tesla Model S, weigh a lot more than their gas-powered counterparts. “Trying to take a corner fast and hard with a car that weighs 4,500 to 5,000 pounds” isn’t easy, Grant told us. “I’m probably 1,000 to 1,500 pounds heavier than every other car in my class.”
Regenerative braking presents another challenge. “It’s like engine braking, as if you were downshifting. You have to take that into account too – it can slow you down pretty far on a really sharp corner, and sometimes that can lead to the back end of the car sweeping out, just because while you’re braking and taking a turn, you lose contact with the tires.”
In a sense, an EV has the opposite attributes of a gas car: it’s slower in the tight turns, but faster on the straight sections. Grant’s competitors know they have to watch out for the Tesla on the straightaways. “I can’t take the corners as fast as everybody else, but when I see a straightaway, with my instant torque and acceleration I can make up some time.”
The Model S is not an ideal autocross car, so Grant doesn’t expect to win a first-place finish any time soon, but his times are improving, and he often earns a respectable place in the top 3 to 5. “It’s very hard to beat cars that are made by the manufacturers to actually go on tracks.” The BMW M3 seems to be the number-one competitor. “They’re very fast and much smaller.”
Grant competes at SCCA events in Southern California in the F Street class, in which cars must be totally stock – the only modification allowed is the tires, so some drivers opt to use “stickier” models. He’s the only Tesla driver on the Southern Cal autocross scene (and apparently the only EV driver, though he has seen a couple of Volts at events), so he and his car get a lot of attention.
Although he’s the only electric driver among a field of car guys and motorheads, Grant says he has encountered no chauvinism or hostility – on the contrary, most of the other drivers find his Tesla Model S very interesting, and are excited about the technology (he does hear some jokes about his vehicle’s silence). This being Southern California, some of the other drivers own Teslas themselves, although they prefer to bring their M3s or Corvettes to the autocross track.
In fact, Grant has become something of a Tesla ambassador to the autocross community – all the car guys have heard about the P100D and its 2.2-second 0-60 time, but he has educated many of them about nifty features such as Autopilot. Everybody wants to take the Model S for a spin, and we all know how that often ends up – it’s possible that Grant has inspired a car guy or two to buy a Tesla of their own.
And why shouldn’t you follow his example? Autocross events are held in all 50 states, and beginning racers are welcome. If you’ve ever wondered how your Model S might perform on a track, an autocross event could be a good place to find out. You’ll have fun, improve your driving skills, and help to spread the word about driving electric.
Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.
Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”
The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.

The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.
Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.
Tesla plans big safety improvements for Full Self-Driving v15
Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.
Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.

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.
