Tesla rolls out 2020 Holiday Update: New Driving Visualizations, Supercharger Display Improvements and more (Release Notes)
Tesla is beginning to roll out its highly anticipated over-the-air 2020 ‘Holiday Update’ that includes new driving visualizations for Full Self-Driving, new games, and an improved display for Supercharger and Vehicle Information, among others.
The following are some of the most notable aspects of Tesla’s 2020 holiday update as part of Firmware 2020.48.25.
Arguably, the Tesla community fan-favorite comes in the form of a new “Boombox” feature that enables the much-talked-about Snake Jazz and Goat easter eggs.
Vehicle Information
Tesla has removed the Tesla “T” from the top menu, which provides better use of the touchscreen display’s real estate. Display improvements can be seen throughout much of the 2020 Tesla Holiday Update.
“The Tesla ‘T’ has been removed from the top status bar. Tap Controls > Software for the same information.”

Release Notes Improvements
Release notes can be accessed under the controls menu. Each feature has been itemized into a tabular left menu that provides quick access to the description for previous and current features.
“Release notes now include improved browsing and access. To view current and previous release notes, tap controls > Software > Release Notes.”
Driving Visualization Improvements
Improved driving visualizations to support Full Self-Driving capabilities take center stage in this year’s highly-anticipated Tesla Holiday Software Update.
“The driving visualization has been refreshed and now offers a larger visualization to allow drivers to view more details of the road surroundings. The next turn will now appear above the visualization if the navigation turn list is covered by another app.
Additionally, select items have slightly moved but will continue to look and behave the same. Some notable differences include the following:
- Quick access to the backup camera and wipers has moved to the bottom bar.
- Indicator lights have been moved to the side of the touchscreen.
- Autopilot set speed, Autopilot availability, and detected speed limit are now displayed next to the driving speed.”
Scheduled Departure Improvements
A refreshed look for the “Scheduled Departure” feature, previously known as “Smart Preconditioning” and released in October 2019, puts more emphasis on a simple design for easier control of charging costs and interior comfort when ready to drive. Tesla notes that Scheduled Departure can operate even when the vehicle is unplugged.
The previous language of not being functional below a 20% battery state of charge is no longer visible.
“Schedule departure can now precondition your battery and cabin even when your car is unplugged. To account for different utility rate plans, you can now set the time when your off-peak rates end to save on charging costs. To access, tap SCHEDULE from the climate control or charging panel when parked.”
Supercharger Display Improvements
Real-time Supercharger occupancy information was rolled out nearly 4 years ago (see version 1.0), and since then Tesla has continued to make user experience improvements for drivers looking to quickly access information from their touchscreen for distraction-free driving. This includes the ability to see available charging stalls at-a-glance and without the need for unnecessary taps of the touchscreen.
“Supercharger pins on your touchscreen will now display the number of available stalls at charging sites. Quickly search for nearby amenities by tapping an amenity icon on the Supercharger popup display.”
Tesla has replaced the iconic Tesla Supercharger lightning bolt icon with a number that denotes the number of currently available chargers at the location.
Emissions Testing Mode Improvements
How can one improve upon Tesla’s famed “Emissions Testing Mode”, better known as “Fart Mode”? Fart at strangers.
“Emissions Testing Mode can be used outside the car. To setup, select your desired sound and place the cushion on the external speaker. When ready, play selected sound by pressing the left scroll wheel button or using the turn signal. To access, tap the Application Launcher > Toybox > Emissions Testing Mode.”
Boombox
Elon Musk has made good on his promise to give Tesla owners the ability to entertain crowds and passersby through honking-fart and goat sounds, plus more.

In addition to several new out-of-the-box sound clips that blast out of Tesla’s exterior speaker, the latest Boombox feature enables the upload of five custom sounds.
“Turn your car into a boombox and entertain a crowd with your media player when parked. You can also customize the sound your car makes when you press the horn, drive the car or when your car is moving with Summon. Select an option from the dropdown menu or insert your own USB device and save up to five custom sounds.”
Tesla Arcade: New Games
Tesla launched a series of new games for its Tesla Arcade collection, including The Battle of Polytopia, Cat Quest, Solitaire, and Boombox.

Last month, Elon Musk teased the community when he tweeted about this year’s holiday software update. Musk hinted that 2020’s holiday update would be “lit.” He also mentioned that the highly-anticipated update would include features that customers wanted, and some that they didn’t even know they wanted.
Last year, Elon Musk and the Tesla team outdid themselves with the holiday software update. Tesla’s 2019 holiday update included a sneak preview of the company’s Full Self Driving suite, TRAX v0.1, and introduced new games to the arcade, such as Stardew Valley and Lost Backgammon.

Tesla Optimus Gen 3 shows off a cleaner, factory-ready design in new app discovery
Renders hidden inside Tesla’s Android app show Optimus Gen 3’s design before any official reveal.
Tesla may have accidentally given a first look at its newest Optimus Gen 3 humanoid robot when photos were found in the Tesla smartphone app.
Design files tucked inside a recent Android version of the Tesla app appear to show the third generation humanoid robot next to the older Gen 2.5 prototype. The assets were extracted from the app package by Tesla community member @wholemars, who posted the renders on X late Tuesday night before deleting them. The Tesla Newswire reshared the side by side comparison on Wednesday, and the images have circulated widely since.

The files are labeled “gen3” and were built as models for Tesla app’s own interface, as validated directly by Grok to be official.
The comparison shows a robot that looks built for a factory line rather than a lab bench. Gen 2.5’s exposed mechanical linkages and gold plating on the knees and shins are gone. In their place, Gen 3 uses matte black fairings on the lower legs, paired with a more contoured champagne gold body. Flexible covers now seal the joint where the torso meets the upper thighs, keeping bearings and moving parts sealed from debris and unnecessary contact.
The body panels fit more tightly, and the hands, which Tesla has said carry 22 degrees of freedom, look far more refined than those on earlier units.
This most recent leak fills a gap Tesla has left open for most of the year. Elon Musk said on March 31 that Optimus 3 was walking around but needed “some finishing touches” before it could be shown, a delay Teslarati covered when Tesla missed its first quarter reveal target. Musk later said Tesla would hold the design back until closer to production, partly to keep competitors from copying it. No reveal date has been announced.
The app itself has been preparing for Optimus for months. In July, code in the Tesla app pointed to a dedicated robot phone key, a consent screen for collecting video and spatial data while Optimus works inside a home, and an alert system for low battery and mechanical faults. Finished 3D models of Gen 3 suggest the interface owners will eventually use is moving past placeholder code toward something Tesla intends to ship.
Manufacturing is moving in parallel. Tesla tore out the original Model S and Model X lines at Fremont this summer to make room for Optimus production, with a planned capacity of one million robots a year. At Giga Texas, the steel frame of a dedicated Optimus factory is nearing completion ahead of a targeted 2027 start, with Musk pointing to an eventual output of 10 million units annually.

Tesla Semi lands the biggest electric truck deal in U.S. history
Tesla leads a record 2,500 truck order, but not every truck will be a Semi.
Tesla has landed the largest electric truck order in U.S. history. ZET SCALE, a new alliance of shippers and carriers, named Tesla its primary manufacturer on Tuesday for an initial order of 2,500 electric Class 8 trucks. The deal alone would nearly double the number of electric heavy trucks operating in the country.
According to the press release from Catalyst Mobility, the nonprofit formerly known as CALSTART, Kenworth, RIDE and Volvo were also selected as secondary manufacturers that carriers can pick if their operations call for it. No split between the four brands has been published, so the exact number of Semis in the order is not yet known.

Tesla won the top slot through a competitive request for proposals. The alliance, which Catalyst Mobility runs with the Smart Freight Centre, scored bidders on price, range, charging capability and production capacity. Pooling freight demand from founding shippers, including Microsoft and PepsiCo, let every truck maker bid lower than it would for a single fleet. “The Tesla Semi is designed for lower cost per mile operations than diesel,” said Dan Priestley, director of the Tesla Semi program, as noted in the press release.
The financing is built to pull in carriers who have avoided electric trucks. ZET Financial is issuing the purchase order for all 2,500 units and will place them with fleets through a fair market value lease. The trucks will be deployed over the next few years across 10 freight hubs in Los Angeles, Stockton, Bakersfield, Seattle and Tacoma, Houston, Dallas, San Antonio, Chicago, Atlanta, and the Newark and New York area. ZET SCALE says the first order is only the opening round, with a longer term goal of 10,000 trucks or more.
Even if Tesla ends up with only a majority share, it would still be the biggest Semi deal to date. Einride’s 500 unit order in August was the previous record, and WattEV’s 370 truck order in May was the largest California deal at the time. Einride’s CEO has since said he expects all 500 trucks delivered by the end of 2027.
The announcement lands two days before Tesla formally inaugurates its Semi factory in Nevada on September 24. The 1.7 million square foot plant sits next to Gigafactory Nevada’s 4680 cell lines and is designed for 50,000 trucks a year.

Tesla integrates Grok Bot into its vehicles for the ultimate personal assistant
Tesla has expanded Grok from an in-car chatbot into a hands-free work assistant. On September 22, Tesla officially launched Grok Bot capability, confirming that drivers can now manage email, calendars, files, chats, and tasks by voice and then hand more ambitious errands to the AI-fueled productivity cheat code.
Grok itself is built by xAI. The new car features split into two layers: Connectors link Grok to outside accounts. Grok Bot, currently limited to SuperGrok Heavy subscribers, can complete multi-step tasks such as placing a usual coffee order, booking a reservation, or scheduling an appointment. It truly puts the driver in a nearly complete hands-free driving and productivity setting, with ironically the only task truly requiring your hands being to touch the “Start Self-Driving” button.
We were granted access to Grok Bot’s Tesla integration a few weeks back, and we’ve been able to do a handful of things with it. On a handful of occasions, we’ve used it to order food and have it ready for pickup slightly later into the evening; we’ve managed to pick up groceries after a day of errands with Grok Bot, and outside of the car, it’s helped with budgeting and even my fantasy football draft.
We’ve been using @Grok Bot in Tesla for a few weeks after gaining Early Access, which we thank the awesome engineers for

Tesla shows another way to utilize it: in their demo, a driver says “Hey Grok,” asks the assistant to check an inbox, and hears that a message concerns a weekend reservation. Grok then scans the calendar, reports no conflicts, and confirms the Tahoe trip is clear. It can also add check-in details to a road-trip itinerary. The point is not novelty chat. It is keeping eyes on the road, or on Full Self-Driving, while the car handles the paperwork of a trip:

This Grok rollout is not a gadget add-on as much as it is Tesla’s thesis in software form: the car should stop being a machine you operate and start being a room you occupy.
Connectors and Grok Bot treat the cabin as an office that happens to move, and that has truly been Tesla’s intention for years now. The car has slowly become an extension of a home more than a vehicle. Inbox, calendar, groceries, takeout, and reservations become voice work, not dashboard chores that you need to do before you get in your car.
Responsibility shifts from the driver to the stack, and as many Tesla owners rely on FSD for travel, Grok Bot now handles the monotony of dinner reservations or appointments.
