Rivian’s latest software update added a ton of new features, including improvements to interior lighting for Gen 1 vehicles, enhanced Google Maps search and traffic data, location photo previews, and climate and Pet Comfort Mode improvements.
With update 2024.31, Rivian added Launch Mode support to their second-gen, Tri-Motor vehicles, including the R1S and R1T.
The first-generation Quad-Motor vehicles don’t have a Launch Mode just yet – but Rivian confirmed they’re working on it, in response to a customer request on X. The Quad Motor configs already come with a Sport Mode preset, which drops the suspension to the lowest, reduces stability controls, provides full power to the motors and warms the battery in preparation for going faster.
With a future update, Gen 1 Quad Motors will have access to Launch Mode – which will bring the maximum possible acceleration to your R1T or R1S. Launch Mode will get you going really fast, really quick.
Rivian already has an older version of Launch Mode on Gen 1 vehicles. You can hold the brake, hold the accelerator, and then release the brake – and off you go!
However, the old launch mode is much simpler and doesn’t offer the full benefits that will come with the new Launch Mode. We’re expecting that Rivian’s new Launch Mode will be even better – with proper UI support, and proper support to get the vehicle motors and batteries to the right temperatures for a perfect launch, every time. Below is a video of Rivian’s old Launch Mode on a Gen 1 R1S.

Rivian transitioned to their second-generation vehicles in 2025. One of the goals with their second-gen vehicles was to reduce vehicle costs, so one of the changes was to reduce battery options for these new models.
Rivian slimmed down its battery pack choices by reducing them from four options to three. Instead of offering Standard, Standard+, Large, and Max battery sizes, they now only offer Standard, Large, and Max batteries packs.
However, to reduce complexity further, initial production runs only had two battery sizes — Standard and Max. For customers who ordered a Rivian with a large battery pack, Rivian actually included a Max battery pack software limited to the range of a Large battery. These vehicles were coined as Large+ (Plus) batteries by the community, and Rivian soon adopted the name.
Advantages of a Large+ Battery
For customers who have a software-locked Max battery, there are several perks. Normally, with a lithium nickel manganese cobalt (NMC) battery, you’d want to avoid charging the vehicle to 100% on a daily basis to prevent premature aging. However, with a software-locked Max battery, customers can actually charge to 100% since the vehicle will stop charging once it hits 100% of the “large” battery.
A Max battery pack can store 140 kWh while a Large is 108.5 kWh, so charging to 100% on a Large+ battery is equivalent to charging to just 78% on a Max battery pack. This lets customers continuously take advantage of their vehicle’s full range without any ill effects on battery degradation — a really nice perk.
However, there’s more. According to Wassym Bensaid, Rivian’s Chief Software Officer, Rivian will soon offer customers the ability to unlock the full benefit of the Max battery pack, essentially purchasing the Max battery after the fact.
This is a really nice option, as some customers may discover they could use the extra range, especially as their battery degrades slowly over the years. It’s not a must-have, but having the option is a great addition.
How to Tell If You Have a Large+ Battery
If you’re not sure if your vehicle has a Large+ battery, you can tell by going to your vehicle settings. Your vehicle should have about 300 miles of range. If it has about 250 miles or 400 miles fully charged, then you have a Standard or Max battery pack.
To check if you have a Large or Large+ battery pack, you’ll need to be in your vehicle and navigate to Settings (gear icon), then tap on the About menu item on the left. You’ll see a rendered model of your vehicle and directly underneath, you’ll see your model, which includes the battery pack size. You should see either Large or Large Plus in the model description.
What You Get By Unlocking
We previously dived deep into Rivian’s battery options for both its Gen 1 and Gen 2 R1 series vehicles, but in short, you can expect your Rivian’s range to increase to the same level as a vehicle with a Max battery pack when unlocking the full capacity of the Max battery.
This will take your Rivian R1S or R1T from about 330 miles of range (531 km) to about 420 miles (676 km), depending on the model.

Price to Unlock Max Battery
While Rivian hasn’t announced the price to unlock the Large+ battery’s full potential, expect it to cost about $6,000. This is the same price as purchasing the Max battery pack at the time of configuring your vehicle, so don’t expect a discount, at least initially.
It’s possible as these vehicles get older, Rivian realizes that people may not want to buy a $6,000 add-on for a 5 or 10-year-old vehicle, and at that point, they may consider lowering the price.
Performance Upgrade: Rivian recently announced the ability to purchase the Performance option for dual motor vehicles as well, so owners of Large+ battery packs can double dip and get the Max battery pack and unlock the Performance version of their vehicle as well. Rivian priced the Performance software upgrade at $5,000, which is also the same price as getting it from the factory.
How to Unlock Large+
While the ability to unlock your Large+ battery pack isn’t available yet, expect the upgrade option to be available in the Rivian app and in the vehicle — similar to the Performance upgrade.
Release Date
Wassym didn’t say when the software battery unlock would arrive, but it seems that it will be coming as part of a future OTA update, which will bring the purchase option to your Rivian. Just like with the Dual Performance upgrade, you’ll be able to use Rivian Reward credits towards the unlock as well.
When purchasing a new Dual Motor Rivian, you might have considered the Performance option, which was offered as a $5,000 upgrade at the time of ordering. However, Rivian is now offering the Performance upgrade as an in-app or in-car purchase for Dual Motor R1S and R1T owners.
The Performance upgrade boosts the vehicle’s horsepower and torque, while also introducing new driving modes.
Features
The Dual Motor Performance upgrade adds additional features to the R1S and R1T vehicles, with the most notable being a major performance boost.
This upgrade increases both horsepower and torque, reducing the 0 to 60 mph time from 4.5 seconds to an impressive 3.4 seconds.
In addition to the power boost, the upgrade introduces new driving modes: Sport, Soft Sand, and Rally. Each mode adds specialized capabilities—Sport for track performance, Rally for off-road adventures, and Soft Sand for tackling sandy terrains.
The Performance upgrade is available for Gen 1 and Gen 2 vehicles.

Launch Mode Reserved for Tri and Quad
Even if you’re familiar with the roller-coaster-like feeling of launching an EV, the performance upgrade is going to be a big step up, and it’ll be a useful upgrade for off-roading too. The noticeable increase in horsepower not only helps you launch with more power but also makes crawling over rocks or pushing through water more effortless.
However, for owners hoping to take their R1 series vehicles to the track, there’s something to keep in mind—this upgrade, just like buying a Dual Motor Performance model, doesn’t include Launch Mode. That feature is only reserved for the Tri and Quad configurations.
Price
If you’re craving a bit more power or want to relive the thrill of launching your Rivian for the first time, the Performance upgrade is likely a great choice. It adds over 120 horsepower, giving you about a 25% boost in performance.
The upgrade costs $5,000 USD / $7,000 CAD, whether purchased over-the-air or at the factory. If you own a Dual Motor Rivian, you can easily buy it through the app or the vehicle itself, available with software update 2024.06 or later.
