What do Tesla software version numbers mean?

By Nuno Cristovao

Everyone loves receiving new updates for their Tesla. But do you know what the version numbers mean and why there are so many versions? We take a look at exactly what Tesla version numbers imply and how Tesla creates and branches their code.

How Tesla numbers their versions

What It Means

A recent Tesla update had version number 2021.32.20 1b7f33580a5f. Let’s take a look at how Tesla numbers their versions and what it means.

The first portion of the version number, 2021, is the year of the release. The second, 32, is the week number of the year. Since Tesla has a history of releasing a major update every four weeks, you’ll almost always see this number in increments of four. After the week number is the revision of the build.

The first build of a release usually does not have a revision and it’s simply known as 2021.32. This is the first build and is only rolled out to a very small portion of the Tesla fleet, if at all.

As Tesla gathers fleet data and learns about any issues, they’ll make improvements and fixes to the release. The next update will have a revision number, such as '.1'. Revision numbers go by incrementally, although not always by one. The number is often arbitrary, but it should reflect the amount of changes in the release. For example, going from 2021.32.1 to 2021.32.2 would often indicate a smaller change than jumping to 2021.32.20.

The revision number should be looked at as a single number and not as a decimal. For example, version 2021.32.2 is an earlier build of 2021.32.20.

Hash

The seemingly random numbers and letters you'll see at the end of a version number is a unique key called a hash that is used to identify that code. A hash is used every time new code is added to a code base and the ones we see in an update are used to identify that specific release.

Gradual Updates

Tesla will often start with a release such as 2021.32 and they’ll gradually roll it out to some vehicles, get data, make fixes and then roll out another release. By the time an update is in wide release, it likely has gone through various revisions and will have a higher revision number.

Tesla releases their updates gradually so that they can minimize any potential issues and keep everyone safe. If there are any major issues with a release, it likely only impacted a smaller portion of the fleet.

Tesla Model Y, the best selling EV in Q1, wins U.S. News 'Best Luxury Electric SUV'

Tesla's Model Y has won U.S. News 'Best Luxury Electric SUV' award. U.S. News writes "Despite the onslaught of new competitors, the Tesla Model Y is one of the most capable and well-rounded luxury electric SUVs that you can buy at the moment," U.S. News added, “If you’re in the market, this is an option that’s well-worth a test drive.”

The Model Y was first delivered to owners in early 2020 and was the automaker’s second mass-market vehicle after the Model 3. The Model Y effectively expanded Tesla’s product line to include a new body style. Tesla’s Model Y has rapidly become the company's best-selling vehicle, despite being more expensive than the Model 3. This speaks to the prominence of the Model Y, dominating the widely-popular crossover SUV sector. 

Tesla's Model Y starts at $62,990, making it much more appealing to mass markets than the Model X which starts at $114,990. Tesla's Model X has been offered for seven years, but is still only produced for sentimental reasons, according to CEO Elon Musk.

U.S. News highlights that, while the Model Y offers less cargo and utility room than the Model X, it still includes many of the same tech features and comparable performance. A fully enhanced Model Y has a 0 to 60 MPH of just 3.5 seconds while still having over 300 miles of range and a 155 MPH top speed.

It's no surprise that the Model Y was the recipient of the U.S. News ‘Best Luxury Electric SUV’ award as it topped the list of best-selling EVs in the US in Q1 2022. In Q1 2022, U.S. EV sales were up 60% year-over-year, demonstrating the continued shift away from internal combustion engine vehicles.

Tesla had the top 3 best selling EVs

Tesla took first, second and third place with an impressive 52,051 registered units for the Model Y, and 47,682 registered units of the Model 3. These two models alone make up the bulk of the entire U.S. EV market. Tesla also achieved third place with 9,250 registrations of the Model S and seventh place is the Tesla Model X with 4,899 registrations. Tesla remains the leader in EV sales, consistently selling a number of vehicles unattainable to competitors.

How to add more 'Quick Control' icons in the Tesla app

Tesla completely redesigned their app with version 4.0 last year. Since then Tesla has been quickly iterating on its features with updates and new features coming every few weeks.

With version 4.3 of the Tesla app, Tesla added the ability to customize the Quick Control buttons on the main screen.

You can add up to four buttons, but with this little trick, you can also add a fifth icon.

Add a Fifth Icon to the Tesla App

To add a fifth icon start by long-pressing the row of icons to bring up an editing screen to sort or replace those icons with the ones you use most frequently.

Now here is where the fun starts because it will take a little manual dexterity to add the additional icon but when you do it correctly your sense of accomplishment will out weight your initial frustration.

Here is the trick:

With your right thumb, pick up one of the available icons and drag it over the fourth icon (in the screen above it is the Front Trunk icon), but do not release it.

While keeping your right thumb held down, use your thumb on your left hand to press on the 1st icon (in the screen above it is the HVAC icon), and drag it to the second icon (the Defrost icon). The icon you have brought up will move offscreen to the right into the invisible fifth spot.

Release both fingers simultaneously and VIOLA a fifth icon will magically appear.

Have fun mixing and matching your icons as your needs change. You can update the icon bar as often as needed.

Video

Tesla used to allow users to continue to add an unlimited amount of icons, but it wasn't a great experience so the total number of icons is now limited to five.

Additional Tips

There are several other useful bits of information about the Tesla app that could make it more useful.

For example, you can tap the battery icon at the top of the screen to access charging information. This brings up the same information as tapping on the Charge Quick Control icon.

If you prefer tapping the battery icon, you can remove the Charge icon from the Quick Controls area, allowing you to free up a spot, essentially giving you an extra Quick Control slot.

Wake Up Your Vehicle Quicker

When using the app most commands are executed through the vehicle's internet connection, which requires your vehicle to be awake.

Waiting for your vehicle to wake up could sometimes take up to a minute, but there is a way to speed it up if you're within Bluetooth distance (around 30 feet).

Some commands are sent via Bluetooth, which allows them to be completed even if the vehicle is asleep. This includes locking and unlocking the doors.

When completing one of these commands, your Tesla starts to turn on almost immediately.

If you're waiting for your vehicle to turn on, you can send a command to lock/unlock your vehicle and your vehicle should wake up quicker than just waiting.

Widget

If you've added a fifth icon to your Quick Controls and use the Tesla app widget, then the widget will now display all five icons as well.

No Need to Wait

With the introduction of the Tesla app version 4.0 last year, Tesla quietly rolled out a feature that changes the way you use the app.

Previously, you needed to open the Tesla app, wait for your vehicle to wake up, and then you could send a command to the car, such as using turning on the climate system or using HomeLink.

However, now you can simply open the app, tap your desired function (it'll show a spinning circle) and you can quit the app.

Instead of the command going directly to your car, it will now be sent to Tesla. Tesla's servers will be the ones who wait for your vehicle to wake up, and when it does, Tesla will execute the command.

If for some reason Tesla isn't able to wake up your vehicle due to a poor connection or another error, then you'll receive a notification saying the command failed.

This makes turning on the HVAC system a much more enjoyable experience.
