FSD Beta v11 Release Notes

Partial release notes have become available and are available below. More to come soon.

- Enabled FSD Beta on highway. This unifies the vision and planning stack on and off-highway and replaces the legacy highway stack, which is over four years old. The legacy highway stack still relies on several single-camera and single-frame networks, and was setup to handle simple lane-specific maneuvers. FSD Beta's multi-camera video networks and next-gen planner, that allows for more complex agent interactions with less reliance on lanes, make way for adding more intelligent behaviors, smoother control and better decision making.

Improved Occupancy Network's recall for close by obstacles and precision in severe weather conditions with 4x increase in transformer spatial resolution, 20% increase in image featurizer capacity, improved side camera calibration, and 260k more video training clips (real-world and simulation).

- Reduced the predicted velocity error of very close-by motorcycles, scooters, wheelchairs, and pedestrians by 63.6%. To do this, we introduced a new dataset of simulated adversarial high speed VRU interactions. This update improves autopilot control around fast-moving and cutting-in VRUs.

- Improved creeping profile with higher jerk when creeping starts and ends.

- Improved control for nearby obstacles by predicting continuous distance to static geometry with the general static obstacle network.

- Reduced vehicle "parked" attribute error rate by 17%, achieved by increasing the dataset size by 14%. Also improved brake light accuracy.

- Improved clear-to-go scenario velocity error by 5% and highway scenario velocity error by 10%, achieved by tuning loss function targeted at improving performance in difficult scenarios.

- Improved detection and control for open car doors.

- Improved smoothness through turns by using an optimization-based approach to decide which road lines are irrelevant for calculating given lateral and longitudinal acceleration and jerk limits as we calculate vehicle kinematics.

- Improved stability of the FSD UI visualizations by optimizing ethernet data transfer pipeline by 15%.

- Improved recall for vehicles directly behind ego, and improv precision for vehicle detection network.

It took a couple of weeks, but we now have CharIN's response to Tesla's public release of the North American Charging Standard (NACS), previously referred to as the Tesla connector.

In a joint statement, the Charging Interface Initiative (CharIN e.V.) and the CharIN North America Chapter made it very clear that there is already a universal standard, CCS, and to move to another standard now would disrupt the industry and delay the transition to electrification.
The CharIN association was formed in 2015, with the purpose of worldwide promotion and support of the Combined Charging System (CCS). Tesla is one of the 155 "Core Members" identified on the CharIN website. However, that relationship didn't buy Musk & Co any subtlety in the association's response.

Tesla held the first Semi delivery event on December 1, and, as always, Elon Musk and his team did not disappoint in revealing interesting details. Not only about the Semi but also about future Tesla products such as the Cybertruck and the 1-MW Supercharger V4.

The Tesla Semi took center stage at its first delivery event on Thursday, which was expected. Nevertheless, Tesla officials, Elon Musk included, could not keep their lips tight about other products either related to the Semi or not. In the first category, Musk revealed interesting details about the megawatt charger used to fast charge the Class 8 truck. In the latter, we also learned new things about the upcoming Cybertruck.

But first things first: the huge battery packs of the Semi require an equally monstrous charging system to top them up in a reasonable time. We knew that already and, based on Musk’s claims about the Semi, speculated that the chargers should be able to pump out 1 MW of power, which was unprecedented. Nevertheless, it seems that Tesla was dead-serious about the performance of its Semi charger.

More than that, the new Tesla Megachargers will turn into the V4 Supercharger poles expected to replace the current-generation chargers starting next year. This is interesting because previous rumors indicated that Tesla would go separate ways with its Semi chargers and the Supercharger network. Previously, the V4 Supercharger was expected to deliver 500 kW of power over a 900-volt connection or to charge two V3-compatible vehicles with 250 kW simultaneously.

During the Tesla Semi delivery event, Elon Musk confirmed that the megawatt charger used by Tesla Semi would roll out to every Supercharger station in the future as the Supercharger V4. The first passenger vehicle capable of using the full power of the V4 Superchargers will be the Cybertruck. This all but confirms that the Cybertruck will have a 900-volt electrical system. Moreover, the cable and the plug connector will remain unchanged, thanks to clever engineering solutions that keep the temperatures down.

According to Elon Musk and Dan Priestley, who is Tesla’s Senior Manager of Semi Truck Engineering, Tesla used immersive-cooling technology, with the high-voltage conductors immersed in cooling liquid. This allowed Tesla to triple the current density over the existing cable instead of using “a giant elephant trunk of a cable,” as Musk said.

“We’re actually immersing the conductors in the coolant,” explained Priestley. “It means that we can really shove a lot of current in a very, very small place. So for those who have charged their cars at a V3 Supercharger and the cable’s nice and maneuverable, it’s the same thing here, but now we’re just shoving a megawatt through it instead.”

Delivering 1 MW of power over the same connector used for Tesla passenger cars makes a strong point for the plug that Tesla wants to make standard across North America. Recently, Tesla open-sourced its connector in a bid to replace the cumbersome CCS plug as the standard connector, at least in the U.S.

Tesla will reorganize the Model 3 production line in Fremont, possibly in preparation for a new vehicle entering production. While many speculate that a refreshed Model 3 is already around the corner, our sources indicate another model might start production in Fremont.

2022 was not a very good year for Tesla, considering that the company barely managed to ship the first Semi trucks to PepsiCo. No other product made the headlines, and the company’s market cap plummeted following Elon Musk’s erratic behavior. Nevertheless, 2023 looks a lot more promising, and people expect Tesla to make good on its promises. Among the products expected to start production next year are the Cybertruck and the HW4 self-driving computer and sensor suite.

Rumor has it that Tesla might have more up its sleeve, and we’ve already discussed several possibilities. Earlier this week, a Tesla enthusiast spotted a camouflaged Model 3 in a parking garage in Santa Cruz. This came at a time when speculations about a refreshed Model 3 were in full swing. Project Highland, as it is now known, aims at making the Model 3 more up-to-date and easier to build as it enters the sixth year of production.

That’s why news about Tesla Model 3 production line being revamped at Fremont made many Tesla fans skip a bit. Teslarati was the first to report on the changes prepared for the General Assembly 3 (GA3) production line, where the Model 3 is being produced. According to their findings, Tesla filed for several revisions to the production lines, namely demolishing the brake and roll equipment where the cars are tested, along with everything associated, and erecting temporary tents where the body fitting and light repair works will be done.

According to the Tesla filings, the temporary tents are so-called Sprung Structures, which have proved incredibly resilient in the past. Such structures are used for the Model Y production in GA4.5. In that case, the temporary structures were installed to accommodate the new production line, but Tesla later filed to make them permanent. We’re confident that Tesla will make a similar move with the tents on the GA3 assembly line.

We know from previous reports that Tesla’s Fremont factory is bustling, working way over its planned capacity. As such, the Sprung Structures tents are the only solution to extend the factory floor. This makes us wonder why Tesla would want to reshuffle the existing production line for a new Model 3. The revamped sedan will indeed feature an entirely new production technique, employing single-piece megacastings. But there’s more to it than a refreshed model.

According to our sources at AutoForecast Solution, Tesla will have another model in production before updating the Model 3. Whereas the electric sedan is planned for production in Fremont no earlier than November 2024, the Tesla Roadster will take the spotlight as early as next summer. We’re not sure a refreshed Model 3 will entice a reorganization of the production line two years before the production start is scheduled. It’s more likely that Tesla will squeeze the Model 3 line to make way for the Roadster.
