The Rivian R1S and the Tesla Model X are two of the premiere choices when buying a large electric SUV. So, we put together a buyer’s guide to help customers search for their EV of choice.

Both the R1S and the Model X are fantastic vehicles, and we’re not here to put one up or the other down. Instead, we’ll be looking at the advantages each vehicle brings – everyone has different needs for their vehicle, and some may favor one over the other.

Price, Range, and Specs

The R1S and the Model X are both unique vehicles in their own right, but each has their own set of configurations that could work better for your family. The table below compares some of the basic specs of these vehicles.

Seating

Rivian Wave

The Model X offers more flexibility in terms of seating, with buyers being able to pick from a 5-seat configuration with a bench seat in the second row and more cargo room or go up to a 6-seat layout with captain chairs and a center row. The 7-seat configuration keeps the bench seat in the second row and the two rear seats in the third row.

The R1S only has a single-seat configuration with a bench seat in the second row and two seats in the third row.

Interior

When looking at the interiors of each vehicle, both are well-equipped and luxurious right off the bat. Both vehicles come in vegan leather alternatives, and the seats are well-designed and comfortable.

Rivian

Rivian and Tesla both have unique interior finishes – the R1S comes with the improved Ascend finish on the Tri-Max and the Quad Max, while the Model X Plaid comes with carbon fiber trim throughout the interior rather than the standard wooden finishes.

Both also have a set of unique internal finishes to choose from, all with high-quality materials. Tesla, for its part, focuses on black, white, and beige, while Rivian offers a wider range of colors. We suggest looking at both interiors online, and in person if you have the opportunity to.

Road Tripping & Families

Both vehicles have some fantastic advantages for both road-tripping, as well as every day errands with the family.

In terms of interior access, the Model X, with its 6-seat layout, offers better access to and from the third row. The falcon wing doors also make it easier for passengers to get in and out of any of the rear seats. Since they’re automated doors and require very little space to open, it’s also easier for kids to get in and out of the vehicle. If your child is in a car seat, the falcon wing doors also provide a significant advantage when putting your child into the car seat since the doors open up over your head instead of swinging outward.

Rivian Wave

On the flip side, the R1S is a larger vehicle all around, and the 7-seat configuration leaves you with plenty of space for a large family. However, third-row access will be more difficult since it requires you to flip down one of the second-row seats. The middle row leaves plenty of space for even taller people to get into. In fact, with three people in the back, you’ll find a considerably larger amount of shoulder room and foot room than in the Model X. If you’ve got a big family or find yourself driving around lots of people, the R1S offers a definite advantage in this area.

Rear Screen

Tesla / Rivian

The Model X comes with a fully capable rear display measuring almost 9 inches, which passengers can use for a wide variety of things, including playing games, watching videos on Netflix, YouTube, or other services, in addition to controlling parts of the vehicle such as seat heaters and the rear climate.

The R1S 6.8-inch rear display is aimed more at being a utility instead of offering entertainment benefits. It’ll let passengers control music, adjust the climate, and see your trip’s progress, but currently doesn’t offer the ability to watch any video content.

Both screens are placed directly behind the center armrest of the front seats, which gives an adequate view for passengers in the second row, but not the third.

Tesla has the advantages hands-down on this one, with the rear screen not only supporting video streaming while the vehicle is moving but also supporting a second channel of Bluetooth audio so that passengers in the back can listen to different content than the front passengers.

Rivian may add video capability to their rear screen in the future. However, it’s not clear whether they’ll support separate audio for the rear display. The Rivian display is also much smaller and has a non-standard ratio, meaning that video content won’t fill the whole screen.

Tesla also provides passengers in the front the ability to control the rear screen. If you have young kids, you can actually bring up the rear screen on the main display in the front and load up a video for your kids.

Storage Space

While both vehicles are considered “SUVs”, the R1S is the clear taker in terms of available storage space, both up front in the frunk, and cargo space in the back. However, the Model X does offer a fairly large amount of storage, and that may be good enough for most people.

Let’s take a look at the overall storage space capabilities of each vehicle.

* This is cubic feet of space, with the third row folded flat in either vehicle.

** Towing specifications depend on tire size and motor options for each vehicle, and a proper weight-distributing hitch may be required. Consult the service manuals for exact details.

Charging

Both the R1S and the Model X are top-of-the-line electric vehicles, and both offer fantastic charging speeds and range.

The R1S offers a maximum charging speed of 220kW, while the Model X offers a maximum charging speed of 250kW. Overall, both vehicles, when pre-conditioned and at a low state of charge, will charge fairly quickly, making them both great choices for road-tripping. Of course, you can also use slower AC charging for either vehicle.

The largest difference in terms of charging is that the Model X is supported at every Tesla Supercharger - the largest and most reliable charging network in North America. The R1S can also be charged at some Tesla Superchargers, but it’ll need to be a V4 Supercharger that has a built-in adapter referred to as the “Magic Dock,” or you’ll need to have a NACS to CSS adapter.

Both vehicles are capable of charging at third-party CCS stations like Electrify America, but the Model X will require a CCS to NACS adapter. The R1S also supports charging at Rivian’s excellent Rivian Adventure Network (RAN) chargers, which are currently limited to Rivian vehicles. These chargers are typically located in adventuring hotspots throughout the continental United States.

Autonomy

On the autonomy front, Tesla is a clear winner – especially if you want a vehicle that can mostly drive itself today with minimal interventions. FSD is an exceptional software package that sees continuous OTA improvements, and for many subscribers and owners of the software – it’s a service that they couldn’t live without.

FSD Supervised today is a fantastic system able to route itself through city streets and highways, and get you from point A to point B, provided you’re paying attention and can intervene if the system can’t handle a situation.

And if you don’t want to use FSD, the Model X comes equipped with Basic Autopilot, which can provide adaptive cruise control and lane assist, as well as all the safety features that come standard on every Tesla.

Rivian, on the other hand, doesn’t offer a full autonomy package, but on their newer Generation 2 vehicles, it does offer some autonomy features that are similar to Tesla’s Basic Autopilot. Rivian is actively working on improving its autonomy software and promises to expand its functionality in the future. Rivian’s Driver+ on their Gen 1 vehicles (2024 and older) provides highway assist on select highways, as well as adaptive cruise control, lane assist, and lane change assist, alongside all of Rivian’s standard safety features.

Overall, Rivian’s package is less capable than Tesla’s today, but it still offers some driver-assist features on the highway.

Comfort & Luxury

When it comes to big SUVs, and especially luxury vehicle purchases in general, comfort is a big aspect in terms of the purchase. Both the R1S and the Model X bring adaptive air suspension, which means both vehicles ride more comfortably than most cars. The R1S does offer a few more adjustable comfort-focused options for its air suspension than the Model X, such as different drive modes, but the difference between the vehicles is remarkably close.

In terms of seat comfort, both the R1S and the Model X have spectacularly comfortable seats. The front seats on both vehicles are heated and cooled, while the second and third rows are limited to heated seats that can be controlled through the rear screen. Neither vehicle brings massage seats to the table, but if that’s a dealbreaker, we suggest waiting for Lucid’s upcoming Gravity SUV.

While the Model X has luxurious additions like auto-opening front doors as you approach, the amazing falcon-wing doors, and the ability to automatically open the frunk or trunk hands-free, the Rivian also has some of its own luxuries.

The Rivian R1S features a powered frunk which can be opened or closed from inside the vehicle or from the Rivian app. It also features some nice additions, such as the built-in flashlight, the optional built-in air compressor, or a dynamic glass roof that can be dimmed at the touch of a button. The R1S also includes customizable ambient lighting and support for surround sound using Dolby Atmos (requires a subscription to Connect+).

Rivian Wave

Software & Software Updates

Both brands offer very software-focused vehicles that receive software updates several times per year, roughly once per month. Both of these vehicles are constantly getting better and will receive new features that keep the vehicle feeling new and exciting. While the software user interface will be a personal preference, Tesla currently has more software features and entertainment options. However, both vehicles include features like Dog Mode / Pet Comfort, Sentry Mode / Gear Guard, Camp Mode, and Launch Mode for performance variants. Tesla and Rivian both like to toss in the occasional easter egg as well.

Summary

Both the Tesla Model X and the Rivian R1S are excellent vehicles in their own right, and each offers a unique and fresh take on the SUV experience. They’re both fantastic EVs, with some of the best battery and motor technology in the business, and you can’t go wrong selecting either one. In general, the Riviam R1S offers a more spacious interior with more cargo room with finer materials, while the Model X offers a more robust driver-assist system, a better charging network, more entertainment options, and a superior seat layout.

We highly recommend you head over to a Tesla Showroom and to a Rivian Space to get acquainted with both vehicles in person.

Rivian Large+ (Plus) Battery Pack Unlock Coming Soon

By Karan Singh
Rivian Wave

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.

Rivian Performance Upgrade: What It Adds and Price

By Karan Singh
Rivian Wave

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.
