Tesla offers Long Range model owners the ability to increase their vehicle's performance
The Kilowatts/Twitter
If you haven't driven a Tesla, you might not be familiar with the rollercoaster-like feeling of going from 0 to 60 mph. The Long Range Model 3, for example, can accomplish this in 4.2 seconds as-is. All Teslas pull you off the line almost instantly and are already quicker than most internal combustion engine vehicles.
What if, though, you could increase the speed of your Tesla even more? We break down what Tesla's Acceleration Boost is, and whether it's worth the price tag.
What Does Tesla's Acceleration Boost Do?
If you drive a Long Range Model 3 or Model Y, you may be able to purchase the 'Acceleration Boost' upgrade that increases your vehicle's acceleration and lowers your 0-60 time.
The Tesla Model 3 Long Range already has an acceleration from 0 to 60 mph time of about 4.2 seconds. With Acceleration Boost, Tesla claims that time is reduced to 3.7 seconds.
The Tesla Model Y Acceleration Boost shaves off half a second on the vehicle’s 0 to 60 mph time, dropping its run from 4.8 seconds down to 4.3 seconds.
It’s worth highlighting that these are the only two vehicles that are eligible to purchase this upgrade. When Tesla first started delivering the new Model Ys with the 4680 cells, owners of the Standard version were able to upgrade, but the company has since removed this option.
Acceleration Boost vs Performance Times
While Acceleration Boost will give you a very noticeable boost in all performance aspects, it will not turn your vehicle into a Performance model.
Here are the 0 to 60 mph time comparisons between the Long Range model, Long Range with Acceleration Boost and Performance models.

As you can see from the table above, a Long Range model with the Acceleration Boost upgrade falls roughly between a Performance model and the Long Range model in terms of acceleration.

The graph above was created by an independent owner and displays the vehicle's performance from 0 to 10, 0 to 20, 0 to 30 and 0 to 60 mph after purchasing Tesla's Acceleration Boost. From the graph we can see how the vehicle's acceleration rate remains fairly constant from 0 all the way to 60 mph.
Does Acceleration Boost Add Track Mode?
Track Mode is a feature that is exclusive to Performance models. It allows you to adjust how your vehicle handles and performs. For example, it allows you to adjust features that may be useful on a track, such as adjusting the motor bias from front to rear, reducing traction control or adjusting vehicle cooling.
Although vehicles with Acceleration Boost have better performance than their Long Range counterparts, they do not include Tesla's Track Mode feature.
Is Acceleration Boost Worth It?
While the Acceleration Boost update can be a costly one at $2,000, it unquestionably gives drivers acceleration capabilities that are comparable to those of the Performance model.
According to Tesla drivers who have purchased the upgrade, the actual acceleration boost is quite notable and affects all speeds, not just 0-60 mph.
On the other hand, your Model 3 or Model Y's quick acceleration will result in quicker tire wear. Additionally, it can result in decreased efficiency, which results in higher ownership costs. However, this does depend on the individual and how often they take advantage of the speed boost.
Performance models are usually quite a bit more expensive than the Long Range models, so in terms of value, the Acceleration Boost upgrade is a good deal that will increase the vehicle's value. If you own your vehicle, you'll also likely recoup some of the upgrade's cost if/when you decide to sell the car or trade it in at some point in the future.
Cost and How to Purchase
The price for Acceleration Boost hovers around USD 2,000, depending on your region and local tax rate. Owners can conveniently purchase the upgrade directly from their Tesla app, or through Tesla's website.
To purchase or see if the upgrade is available for your vehicle, open the Tesla app and navigate to the Upgrades section.
Then tap on Software Upgrades and if the feature is available for your Tesla you will see Acceleration Boost listed.
If you'd like to purchase the upgrade, make sure your vehicle is in Park and connected to Wi-Fi or has a strong cellular connection so that the vehicle can download an updated configuration.
You can add the Acceleration Boost upgrade to your cart and follow the payment instructions.
The upgrade is a one-time payment that can be made with a credit card, debit card, or Apple Pay. However, it is not possible to add the cost of the upgrade to your lease or vehicle loan payments.
Once the payment has been processed, the update should only take a few minutes to show up in your vehicle.
How to Check if Your Vehicle Has Acceleration Boost
Once you've made the purchase, you can confirm that you have received the upgrade by tapping on Controls (car icon) and navigating to Software. Below your vehicle's image, you'll see a list of features, including possible features like Full Self-Driving, Premium Connectivity and more.
If your car has received the upgrade, you should now see Acceleration Boost listed.
In addition to the upgrade appearing under the Software tab, you can also navigate to the Pedals & Steering section and your acceleration choices will now be 'Chill' and 'Sport,' instead of the previous options of 'Chill' and 'Standard.'
Your vehicle should now be noticeably faster.

Is there an Acceleration Boost Trial?
Although not formally promoted as a trial period, Tesla does provide you the chance to get a refund for your original purchase within 48 hours of purchase, if you change your mind or the upgrade didn't meet your expectations.
It is not possible, however, to receive another refund if you re-purchase the Acceleration Boost upgrade at a later time. Any future purchases for Acceleration Boost will be final.
The Acceleration Boost upgrade might be worthwhile for you if you frequently travel on long, open highways or appreciate experiencing the acceleration surge when you depress the pedal. But if you use your Tesla for routine activities like grocery shopping or being stuck in traffic on the way to and from work, it might not be the best bang for your buck.
However, if you initially had your eye on the Performance model and ultimately decided on the Long Range version, Acceleration Boost is a great way to get closer to the performance of the higher-end trim.

Tesla has officially announced the next major software update, 2025.26. As expected, this update will introduce the Grok AI assistant to Tesla vehicles, although it’ll initially be limited to the U.S.
Tesla also announced several other features that will arrive in update 2025.26, such as Light Sync, the ability to create and save audio presets, and others.
We’ll break down each new feature and which models and regions we expect it to be available in.
As expected, Grok will only be available on AMD Ryzen-based vehicles. Tesla says that it will also be limited to the United States and require Premium Connectivity, but it looks like it won’t require a subscription to anything else, such as Super Grok.
Unfortunately, Tesla announced that Grok will not be able to control elements in your vehicle and that the old voice command system will still be used to do that.
In a post on X, Tesla showed off Grok in action for the first time, showing the interaction between the driver and Grok. The Grok interface displays sound waves in rainbow-like colors when it’s speaking, much like another popular device. Tesla’s video of Grok is below:
Supported vehicles: Based on Tesla’s post, this is expected to include all AMD vehicles, including the Model S, X, 3, Y, and Cybertruck.
Supported regions: U.S.
Light Sync
Not a Tesla App
Tesla continues to improve the ambient light feature in Teslas by integrating it into more things. Tesla recently started using the ambient lights during Santa Mode and Rainbow Road. They also turn the ambient lighting red when you’re in Service Mode. However, this time, they’re going one step further. The ambient lights can now react to the music you’re playing by presumably changing colors based on the beat.
You’ll also have the option to maximize the brightness of the ambient lights when this feature is enabled, but only when the vehicle is parked, which Tesla is calling Rave Cave.
In addition to reacting to the music, the lights can change color to match the album color of the music being played, which is kind of similar to the ambient lights on some TVs matching the content being displayed. A needless addition? Sure. But very cool as well.
Tesla shows a screenshot of this feature, which is included in the Toybox app, and shows that you can enable or disable each feature individually, including syncing the lights to music, max brightness, and matching the album artwork color.
Supported vehicles: All vehicles with the ambient lighting feature, including the Cybertruck.
Supported regions: Assumed to be available everywhere.
Audio Settings Update
Not a Tesla App
Another feature Tesla highlights is the ability to create presets for audio settings. These audio settings will be in a new Audio tab in the vehicle’s settings, and they’ll allow you to create and save presets for different types of music. For example, you can have a preset for spoken content and another one for pop music.
Each preset will let you adjust the equalizer and set the immersive sound level.
What’s nice here is that it seems that Tesla has redesigned the audio settings and moved them to the main vehicle controls instead of only having them accessible through a button in the music player. You can see the Balance tab at the top, although it doesn’t look like you’ll be able to save the balance as part of the preset.
Supported vehicles: This is expected to be available on all vehicles, although it could exclude the legacy Model S/X.
Dashcam Viewer Updates
Not a Tesla App
This Dashcam Viewer update is only for AMD-based vehicles. It includes the ability to change the playback speed of the video being played, a feature of the old Dashcam Viewer which was surprisingly not included in the new player.
The playback speed is shown on the screen, and you’ll be able to tap it to cycle between varying speeds. The older Dashcam Viewer lets you choose between 0.5x, 1x, 1.5x, and 2x playback speeds, and this is expected to be the same in this update.
With this update, the new Dashcam Viewer also arrives on the Cybertruck for the first time, which was the only Ryzen vehicle excluded when the update was originally released.
Supported vehicles: All AMD Ryzen-based vehicles.
Supported regions: Assumed to be available everywhere.
This isn’t as exciting a feature, but it surely prevents a lot of unnecessary frustration for users who arrive at a Supercharger location only to find out it requires you to pay for parking, is only available for valet service, or has other requirements.
If the Supercharger is in a garage, Tesla will now include the floor or level number that the Supercharger is on. While there are usually physical signs at these locations, knowing the floor number the charger is on ahead of time will definitely make it easier to find.
Supported vehicles: Expected to be available on all vehicles.
Supported regions: It’s not clear whether this will be available in all regions.
Onboarding Guide
Not a Tesla App
The last feature that Tesla is highlighting in update 2025.26 is a new onboarding guide that will help new owners become familiar with their vehicles.
According to Tesla, the new guide will run through several features, such as adjusting your seat and mirrors, as well as controlling certain vehicle functions, including the lights, wipers, and Autopilot. This will be a great addition for new owners, as accessing some of these features isn’t apparent, especially if they require use of the unlabeled scroll wheel, such as activating Autopilot on newer vehicles without a stalk.
Supported vehicles: This is expected to only be available on AMD Ryzen vehicles, but Tesla doesn’t specify which vehicles it’ll be available on. Once the update starts rolling out, we should have more information.
Supported regions: This will likely be available in all or most regions.
Release Date
There may be other features included in update 2025.26 that Tesla isn’t highlighting in their post. Tesla often doesn’t include smaller additions or features that were previously introduced but have now been added to more regions.
There’s no doubt that the biggest feature in this update is Grok, but the other updates are nice improvements as well. This feature is expected to roll out to employees this weekend, and it should start rolling out to customers in the next week or two.
Tesla is moving to aggressively expand its Robotaxi Network at a rapid pace, with new information revealing that an expansion into Arizona is imminent, pending, of course, regulatory approval. Tesla has already begun looking at building out the program to other cities, just weeks after the launch of its pilot program in Austin, Texas.
Phoenix, Arizona, is Next
In a letter received following a query submitted by Sawyer Merritt, the Arizona Department of Transportation (AZDOT) has confirmed that Tesla had officially applied for Robotaxi permits on June 26th, 2025. According to AZDOT, Tesla had applied for the permits for both autonomous vehicle testing and operation with and without a safety driver.
The department also confirmed that Tesla has expressed its interest specifically in operating within the Phoenix Metro area, with a decision on the permits expected by the end of July. This is the first official step to establish Robotaxi within a second state, which is exciting to see.
Tesla Hiring Vehicle Operators
The move into Arizona isn’t an isolated event. It’s the first step in a broader national expansion, as per Tesla’s recent job postings for Robotaxi Vehicle Operators and FSD testers on Tesla’s Careers page.
These positions, which are necessary for Tesla to launch and validate the service in new locations, show us where Tesla plans to deploy Robotaxi next. The areas include:
Tempe, Arizona
Palo Alto, California
Fremont, California
San Diego, California
Henderson, Nevada
Jacksonville, Florida
Tesla is simultaneously laying the groundwork for expansion in at least three other states besides Texas and Arizona, and that’s a good sign for the network’s quick expansion. Tesla’s executive cadre pointed to a timeline of late 2025 for Robotaxi to be deployed in multiple cities across the United States, and it appears that this timeline is on track.
The Scalability Advantage
This strategy of pursuing multiple markets in parallel highlights the advantage of Tesla’s generalized autonomy approach. Because FSD is designed to be a generalized solution that learns from a global fleet, Tesla does not need to spend years meticulously pre-mapping every street in a new city.
Instead, it can target new locations and use a smaller fleet of operators to validate the performance and safety of FSD within a new environment. After all, every city has its own unique traffic regulations and environmental considerations that need to be understood.
The key here is that Tesla can turn on a fleet in a whole new location in just a fraction of the time required by other methods, such as HD mapping - which can require hundreds of mapping vehicles, thousands of hours of real humans driving, and many hours of engineering to get all the data cleaned up and ready for use.
The Austin pilot is just the beginning of Robotaxi. Tesla is already planning to expand the geofence this weekend and plans to scale the network to other cities soon.
