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.

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.

** 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.

Tesla Semi Keynote: New Features, 46 Charging Sites, Upgraded Battery & More [VIDEO]

By Karan Singh
Out of Spec BITS/YouTube

Tesla’s Dan W Priestley attended the Advanced Clean Transportation (ACT) Expo in Anaheim, California, and provided an update on Tesla’s Semi truck program. The presentation covered several key developments on the status of Tesla’s Nevada Semi Factory, refinements to the Semi, and Tesla’s plans for charging and ramping production through 2026.

Let’s dig in and take a look at everything that was captured by the Out of Spec team at ACT Expo. The original video is embedded below if you’d like to watch it.

Semi Factory & Production Ramp

Priestley reaffirmed the timelines mentioned during Tesla’s Q4 2024 Earnings Call that Tesla will scale Semi production in 2026. To achieve this, Tesla has been actively building and expanding the Gigafactory Nevada site, specifically to support the production of the Tesla Semi. The dedicated Semi facility will have a targeted annual capacity of 50,000 Semi trucks.

Following the beginning of production, Tesla will utilize the initial trucks to integrate into its own logistics operations. This will serve as both a final real-world testing ground as well as an opportunity for Tesla to gather data internally. Tesla plans to begin subsequent customer deliveries throughout 2026 as the ramp-up continues.

Reuters also reported that Tesla is hiring over 1,000 new employees at the Semi Factory to begin the rapid ramping of the program.

Semi has already amassed 7.9 million miles with Tesla’s current testing and operational fleets, providing some real-world data and testing. Feedback for the truck has been exceptionally successful, with many drivers praising the Semi’s performance and comfort.

New Tesla Semi Features

Of course, it wouldn’t be a Tesla keynote without showing off some new things. The Semi will be available in 500-mile and 300-mile range configurations, now featuring updated mirror designs and a drop-down glass section to improve visibility and allow easier interaction with external elements—such as control panels at ports, for example.

New Electric Power Take-Off (e-PTO)

The Tesla Semi will also feature a new capability called Electric Power Take-Off, or e-PTO system. Similar to the PTO systems found on other vehicles, this will allow the Semi’s high-voltage battery to power auxiliary equipment at variable voltages. That includes being able to power things like climate-controlled reefer trailers, potentially replacing the noisy and polluting diesel generators traditionally used for this purpose.

Charging and Batteries

Tesla is also working on an updated battery pack design for the final production design of the Semi. This new pack is designed to be more cost-effective to manufacture. The battery pack itself is slightly smaller than before, but the truck maintains the same level of range through efficiencies. Dan also confirmed during his keynote that the battery cells for the Semi will be sourced domestically inside the United States, helping to alleviate potential burdens due to tariffs.

On the charging front, Tesla is using MCS - the Megawatt Charging System - capable of 1.2MW - and designed specifically for Semi. The system uses the same V4 charging hardware found at Supercharger sites but focuses on that larger power output. Alongside a smaller physical footprint, Tesla will be able to configure these V4 cabinets for either dedicated Semi charging or for shared power scenarios with regular Superchargers. Tesla is also working on an integrated overnight charging product, but Tesla isn’t ready to talk about it yet.

46 Semi Charger Sites Coming

Finally, Tesla has made substantial investments in a public charging network for the Semi. There are currently 46 sites in progress throughout the United States, and plans for significant expansion throughout 2026 and 2027. These sites are strategically located alongside major truck routes and within industrial areas to support long-haul and regional operations. Tesla is aiming to offer the lowest possible energy costs to operators to help incentivize adoption.

This was one of the best updates to the Tesla Semi we’ve received since its initial unveiling. It seems that the Semi will receive a big portion of Tesla’s attention in 2026, while Robotaxi and FSD Unsupervised take the stage this year.

The Tesla Semi has the potential to transform transportation even more dramatically than EVs already have, serving as a testament to Tesla’s mission to electrify the world.

Tesla’s B-Pillar Sentry Mode Recording Requires HW4, Not Just Ryzen — Breakdown of Spring Update Requirements

By Karan Singh
Not a Tesla App

Sentry Mode is an invaluable tool for owners - capable of keeping the vehicle safe and secure even when you’re not around. This is especially true in recent times, with the misguided and unfortunate incidents surrounding Tesla ownership, including damage to Tesla vehicles, showrooms, and Superchargers.

B-pillar Camera Recording and Dashcam Viewer

With the 2025 Spring Update on 2025.14, Tesla is expanding Sentry Mode’s functionality for certain vehicles with some much-needed changes. Sentry Mode and Dashcam can now record footage from the vehicle’s B-pillar cameras. These cameras are located on the side pillars of the vehicle, between the front and rear doors.

This adds two crucially needed viewpoints, making Tesla’s Sentry Mode a truly 360-degree security system. These cameras also provide the best angles for capturing license plates when parked, so they will be greatly appreciated by owners in the event of an incident.

These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view. It also allows users to jump back or forward in the video in 15-second increments.

However, to the disappointment of many owners, not all vehicles are receiving these updates due to the additional processing power needed.

Limited to Hardware 4 Vehicles, Ryzen Isn’t Enough

We have confirmed that Tesla is only adding the additional camera recording and improved Dashcam Viewer on hardware 4 (HW4 / AI4) vehicles. The newer hardware presumably has the additional processing power and bandwidth needed to handle recording and saving the two additional video streams during Sentry Mode and Dashcam.

For the time being, owners of HW3 vehicles are not receiving this feature. This includes all vehicles with HW3, even those with AMD Ryzen infotainment systems. If you’re not sure whether your vehicle has HW3 or HW4, you can refer to our FSD hardware guide.

While there’s no doubt that recording two additional camera streams would be more computationally intensive, we hope that Tesla adds the improved Dashcam Viewer to HW3 vehicles in a future update.

Cybertruck Also Missing Improved Sentry Mode

Surprisingly, and most confusing for many - is the fact that the Cybertruck is also not receiving the improved Dashcam Viewer and B-pillar camera recording with this update. This struck us as odd, especially since the Cybertruck is currently the only vehicle with the improved, more efficient version of Sentry Mode.

Every Cybertruck is equipped with HW4 and AMD Ryzen infotainment units, so this clearly isn’t a hardware restriction. It’s possible the more efficient Sentry Mode is playing a role here due to the infrastructure changes. However, we expect Tesla to address this in a future update and eventually release these features for the Cybertruck as well.

Given the Cybertruck’s high visibility and its status as a frequent target for both positive and negative attention, many owners hoped that the Cybertruck would be one of the vehicles to receive this feature.

Adaptive Headlights

Tesla finally started rolling out its adaptive headlights in North America. While the new Model Y already came with the feature when it was released last month, other vehicles with matrix headlights are now receiving the feature in the Spring Update.

All vehicles with matrix headlights are receiving this feature, which includes the new and old Model 3, first-gen Model Y, and the new Model S and Model X.

If you’re not sure if your vehicle includes matrix headlights, check out our guide. What’s interesting here is that older vehicles that were retrofitted with matrix headlights due to an accident or user replacement are also receiving the adaptive headlights feature.

Legacy Model S & Model X

As with most updates, the older legacy Model S and Model X are not receiving all the features included in this update. Unfortunately, some of the features, which include the Blind Spot Camera on the instrument cluster, Save Trunk Height Based on Location and Keep Accessory Power On are limited to the new Model S and X.

Legacy S and X models will receive the Alternative Trip Plans feature, Avoid Highways (Requires Intel MCU) and the Keyboard Languages feature.

These vehicles are also receiving all the features in the Minor Updates section except for the visualization showing how far the door is opened, which is exclusive to the Cybertruck. These additions include improved music search results, contact photos in the phone app, automatic connecting to hotspots, the ability to show third-party chargers, view Supercharger amenities, and various improvements to music services.

While many users will be disappointed not to receive the B-pillar camera recording and Dashcam Viewer improvements, it’s important to remember that Tesla typically does a great job at bringing features to older vehicles, at least with the Model 3 and Model Y. If a feature isn’t added, it’s usually due to a hardware limitation.
