What the Acceleration Boost upgrade does
Tesla's Acceleration Boost is a paid software upgrade that increases the maximum power output of your Model Y's electric motor, reducing the time it takes to reach 60 mph. The upgrade does not add a new motor or battery — it changes how much electrical power the existing drivetrain can use at once. Think of it as unlocking a higher performance setting that was already built into the car's hardware.
The exact acceleration improvement depends on which Model Y model you own. On a Long Range Model Y, the boost typically cuts about 0.5 seconds off the 0-60 time. On a Performance Model Y, which already accelerates faster, the improvement is smaller because the car is already operating closer to its maximum. The upgrade costs a fixed amount and is a one-time purchase tied to your vehicle's VIN.
Once purchased, the boost is permanent. It stays with the car even if you sell it, and the new owner inherits the upgrade. You cannot turn it off or on — it becomes your car's new baseline performance level.
Key Takeaways
- Acceleration Boost is a software change that increases motor power output, not a hardware addition, and reduces 0-60 time by roughly 0.5 seconds on Long Range models.
- The upgrade is purchased through your Tesla account, costs a fixed amount that varies by market, and is tied permanently to your specific vehicle's VIN.
- Battery range, charging speed, and everyday driving are not affected by the upgrade — only maximum acceleration performance changes.
- You can purchase the boost through the Tesla app or your vehicle's touchscreen, and the change takes effect when ready after payment.
- The upgrade transfers to any future owner of the car and cannot be disabled once purchased.
How to purchase the upgrade through your Tesla account
You buy Acceleration Boost directly from Tesla using the Tesla mobile app or the vehicle's center touchscreen. Open the Tesla app, tap the car icon at the bottom, then select "Shop" or "Upgrades" — the exact menu name varies by app version. You will see Acceleration Boost listed as an available purchase if your Model Y is may be able to access.
Tap the upgrade, review the price (which appears in your local currency), and confirm the purchase. Payment goes through the payment method already linked to your Tesla account. The entire process takes about two minutes. Once payment clears, the upgrade activates within minutes, and you will see the new acceleration performance the next time you drive.
If you prefer to purchase through the car itself, touch the Tesla "T" logo on the center screen, go to "Service," then "Shop," and follow the same steps. Both routes use the same account and payment method, so it does not matter which you choose.
What changes and what stays the same after the upgrade
After purchasing Acceleration Boost, your Model Y's 0-60 time improves, but almost nothing else changes. Your maximum top speed may increase slightly, and the car reaches highway speeds more quickly. The battery range, charging time, and efficiency remain the same — the upgrade does not drain the battery faster during normal driving.
Everyday driving feels identical. The boost only affects maximum acceleration, which you use when you press the accelerator pedal all the way down. Normal city driving, highway cruising, and Autopilot behavior are completely unchanged. You will not see a difference in energy consumption unless you regularly drive at maximum acceleration.
The upgrade also does not affect warranty coverage, software updates, or any other Tesla service. Your car continues to receive the same over-the-air updates and service support as before.
Price and regional variation
Acceleration Boost costs a fixed amount that Tesla sets per market. The price is the same whether you own a Long Range or Performance Model Y, even though the performance gain differs slightly between them. Pricing varies by country and region because Tesla adjusts for local market conditions and currency.
You can see the exact price in your Tesla app before you purchase — there are no hidden fees or additional charges. Some owners have reported that Tesla occasionally runs promotions or discounts on the upgrade, though these are not may provide and do not happen on a regular schedule.
Whether the upgrade is worth the cost
Whether Acceleration Boost makes sense depends on how you drive. If you regularly use maximum acceleration — merging on highways, racing from traffic lights, or enjoying spirited driving — you will notice and use the improvement. If you mostly drive at steady speeds and accelerate gently, the upgrade will have almost no impact on your daily experience.
The boost is also a personal preference about the car's character. Some owners want the fastest possible acceleration for the satisfaction of it, even if they rarely use it. Others see it as unnecessary because the Model Y already accelerates faster than most gas cars. There is no objectively correct answer — it depends on what matters to you.
One practical consideration: the upgrade is permanent and transfers with the car. If you plan to sell the Model Y in a few years, the boost adds to the car's resale value, though probably not dollar-for-dollar with what you paid for it.
How Acceleration Boost compares to other Model Y performance options
Tesla offers performance upgrades in different ways. The Performance Model Y comes with higher acceleration from the factory, a lower suspension, and larger wheels — it costs significantly more than a Long Range model. Acceleration Boost is a cheaper way to get some of that speed improvement without buying a different car.
If you already own a Long Range Model Y and want better acceleration, Acceleration Boost is your only option short of trading the car in. You cannot upgrade to a Performance drivetrain after purchase. If you are shopping for a new Model Y and performance matters to you, comparing the cost of a Performance model against the cost of a Long Range plus Acceleration Boost can help you decide which route makes sense financially.
Frequently Asked Questions
Does Acceleration Boost use more battery power?
The upgrade does not change battery consumption during normal driving. It only affects what happens when you press the accelerator all the way down. If you drive conservatively, your range stays the same. If you regularly use maximum acceleration, you may see slightly lower range because you are drawing more power more often, but this is true of any car.
Can I return or refund the Acceleration Boost upgrade?
Tesla's refund policy for Acceleration Boost varies by region and circumstances. Contact Tesla Support through the app or your account to ask about refund options in your area. Some regions allow returns within a specific window; others do not. It is worth asking, but do not assume a refund is available.
Will Acceleration Boost affect my warranty or insurance?
The upgrade does not void your warranty or change your coverage. Tesla considers it a standard software feature, not a modification. Your insurance company may not even know about it, and it should not affect your premium. If you are concerned, contact your insurance agent to confirm.
Does the boost work with Autopilot or only when I drive manually?
Acceleration Boost only affects manual acceleration — when you press the pedal yourself. Autopilot and other driver information features use their own acceleration profiles and are not changed by the upgrade. The boost is purely for when you are actively driving.
What if I buy a used Model Y that already has Acceleration Boost?
The upgrade transfers to you automatically when you become the registered owner. You do not need to purchase it again or do anything to set up it — it is already part of the car's performance. You inherit the boost as part of buying the vehicle.
