Enhanced Highway Assist for Gen 2 vehicles

The company’s latest software update is deploying the new Enhanced Highway Assist to Gen 2 vehicles, which will let drivers take their hands off the wheel for extended periods of time, not unlike Tesla’s Supervised Full Self-Driving (FSD). For the time being, the feature is being offered to owners for free, though it’s not clear if Rivian plans to eventually start charging for the suite.

Enhanced Highway Assist is able to control the vehicles’ steering, acceleration, and braking, and Rivian also uses an infrared cabin camera embedded in the interior rearview mirror to monitor driver attention.

Rivian Autonomy Platform

In the press release dedicated to its autonomy program, Rivian notes that its vehicles include a multimodal suite of 11 cameras and five radars, offering sensor redundancy and a 360-degree view. The company also says that its internally developed cameras have the highest resolution of any vehicle in North America, while its radar systems are intended to help detect objects over longer distances and in low-visibility conditions.

“We are excited to continue releasing new updates and dramatically expanding our autonomy features,” Philbin said. “Everything on our Gen 2 roadmap is capable with the hardware on our vehicles today.”

Rivian says its vehicles also include an on-board compute module that’s capable of more than 200 trillion operations per second, while the company’s machine learning models are trained on the latest ML research and transformer architectures.

Performance Upgrade for Dual-Motor (Gen 1 and Gen 2)

Rivian has also debuted a $5,000 Performance Upgrade for Gen 1 and Gen 2 vehicles with the Standard+, Large and Max battery packs, unlocking 665 horsepower and 829 lb.-ft. of torque. The upgrade also adds three new drive modes, dubbed Sport, Rally, and Soft Sand, to the currently available All-Purpose, All-Terrain, and Snow modes.

Owners can purchase the upgrade from the Rivian mobile app or account page, and it will be downloaded to the vehicle through an over-the-air (OTA) software update.

Rally Mode comes to Performance Dual-Motor vehicles

The update also adds Rally Mode to Performance Dual-Motor vehicles, offering heightened throttle response, crisper steering on just about any terrain. To use the feature, drivers will simply need to switch into Off-Road mode, which will let them select Rally Mode.

Wheel Swap

Owners will now be able to change the vehicles’ wheel type in the settings menu, offering improved range estimates.

Go Chime

Rivian has added an audible chime for when a stopped vehicle ahead starts moving, signaling to the driver that they can start driving too. The chime will first be added to the EV maker’s Gen 2 models, before later rolling out to Gen 1.

Side Mirror Auto-Tilt on Reverse

When drivers shift into reverse, Rivian’s sideview mirrors will now automatically tilt downward to show the curb and road, making parallel parking easier. This feature will also go out to both Gen 1 and Gen 2 vehicles.

Control Chargeport Door from Mobile App

Drivers will now be able to control their charging port door remotely using the mobile app, adding an extra layer of protection for those who walk away without closing it manually.

Tire Puncture Detection

Rivian has added proactive detection for tire punctures and slow leaks, set to notify drivers of a potential flat tire before it happens.

Elon Musk and Trump are closer than ever, and Tesla could be the big winner

Elon Musk sat beside Trump as AI leaders signed a voluntary White House safety accord.

Elon Musk had the seat right next to President Donald Trump on Tuesday as the White House hosted the leaders of America’s biggest artificial intelligence companies for a lunch that ended with a voluntary industry accord on AI safety.

A seating chart Trump posted on Truth Social placed Musk at the president’s left in the East Room, with Nvidia CEO Jensen Huang on his right, according to an Associated Press reporter. Anthropic CEO Dario Amodei, OpenAI President Greg Brockman, Meta’s Mark Zuckerberg, Google’s Sundar Pichai, Microsoft’s Satya Nadella and Amazon founder Jeff Bezos also attended, along with Vice President JD Vance and House Speaker Mike Johnson.

After the lunch, Trump told reporters outside the West Wing that the executives had signed “The White House Accord on Superintelligence: A Joint Commitment on Frontier SI Responsibilities.” Johnson described it as a voluntary statement of principles built on “robust internal controls and layers of internal and external review,” while Zuckerberg said company boards would independently review reports from outside auditors. Trump called the document “morally binding,” said he would name a new AI czar within days, and signed an executive order formally renaming artificial intelligence “super intelligence,” CNBC reported.

Musk was not in the room for Tesla alone. Since SpaceX absorbed xAI, he runs the company behind Grok and one of the largest AI training operations anywhere. On September 25, he said another 220,000 Nvidia GB300 chips would come online at Colossus 2 within a week, with more expected in November and December.

Musk also used the trip to restate his energy ambitions. “SpaceX is aiming together with Tesla to do 200 gigawatts of solar production per year,” he said at an event in Washington. It is the same combined target he laid out that feeds directly into Terafab, the Tesla and SpaceX chip venture that will need enormous amounts of power.

The showing between Musk and Trump has come a long way, since the two had the very public split in mid 2025 after Musk opposed the “Big Beautiful Bill” and left DOGE. They reconciled at Charlie Kirk’s memorial that September, and Trump later called their relationship “good”. Since then, Musk has joined Trump’s China delegation in May and attended last week’s White House state dinner for Chinese President Xi Jinping.

For Tesla, that access to government official could pay dividends. As Teslarati noted in January, federal autonomy rules, NHTSA oversight and a single national standard for driverless vehicles all run through an administration Musk can more easily reach directly as Tesla works to scale Robotaxi and Cybercab beyond Texas.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong

Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.

Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.

Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.

In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.

Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.
