Halloween is just a day away. Are you ready to sport all of your Rivian’s new Halloween features? Rivian added various features in their annual spooky update with Rivian update 2024.39. This year, Rivian has gone all out, with not one but three Halloween car costumes and various other features.
The car costumes are selectable through the Rivian app when the vehicle is parked - and so are all the other fun features.
Halloween Update
Rivian’s Halloween update this time is the biggest it's ever been. Before we dig into the Car Costumes, let’s take a look at the sprinkling of other spooky features they’ve provided.
New Drive Mode Animations
First up is the drive modes menu. Every drive mode in your vehicle has taken on a spooky look, so pan through your available drive modes while you’re parked to see all the Halloween fun. Look closely because some of the spooky surprises are well hidden. The only mode that doesn’t have a spooky surprise is snow mode.
Camp Mode also got a little something special. The flame of the campfire is lit by some witch’s evil magic and is burning green alongside some pumpkins and crows in the background. And just like last year, pedestrians are zombies - but that’s not all. Motorcyclists and bicyclists take on a new form in the visualization - they’ve come back as headless horsemen.
Rivian has also introduced two additional lock sounds for Halloween, an owl and a crow. While all of the Halloween goodies will go away once the season is over, Rivian has already said that the owl lock sound will come back as a standard lock sound in the future.
There are also two new interior lighting modes, the red Crimson Moon, and the green Foggy Bog. To go with that, there’s a new selection of three songs to play internally, as well as a sound effect board, all done from within the Rivian app.
The best plan is to play some spooky sound effects while your Rivian is parked outside on Halloween night to give some trick-or-treaters a fright!
The Costume Selector in the App
Rivian Wave
Knight Rider Car Costume
The Knight Rider costume dresses up Gear Guard Garry as Michael Knight and K.I.T.T.'s super intelligence takes over your car in the classic original TV show style. On Gen 2 vehicles, the lightbar up front will mimic K.I.T.T.’s unique red beam scanner, including the sound effect!
The Knight Rider interior screens

Over in the interior, you’ll get three unique displays inside your vehicle. On the driver’s display, you’ll see revs, speed, and a ton of other information, while the main display will tell you all about how ready K.I.T.T. is to tackle the bad guys. Finally, the passengers will have access to the tools K.I.T.T. has access to - everything from energy cannons and radars to Missiles and Turbo Boost.
Back to the Future Car Costume
Back to the Future dresses up Garry as none other than Doc Brown, and you’ll get a super cool set of movie-inspired interfaces on the inside of your vehicle. Gen 2 owners can hit the 88 mph button on their driver’s display and engage in Back to the Future-themed interior and exterior lighting, along with sound effects to match.
The Back to the Future Interior Screens

The driver’s display has all the information you’ll need to get your flux capacitor up and running, telling you all about the plutonium chamber and power you’ll need to hit 88 mph. The primary display will tell you when you’ve got your destination, what time it is now, and when you originally departed. The passengers get to keep an eye on the flux capacitor, and dial in the destination time!
Trunk or Treat Car Costume
Trunk or Treat has Garry as a scarecrow this year and has eight different sound effects and three color themes. That’s also alongside the option to select the thematic music for the interior of your vehicle.
All three interior screens will be haunted by ghosts and static, and Gen1 vehicle owners will get a green animation on the lightbar. Gen 2 owners will have their lightbar match their selected color.
Video Overviews
Jenna Ezarik over on X put together this awesome recap - so go take a look.
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.
