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’s Hollywood Diner: In-Car Controls & Theater Screens Turned On [VIDEO]

By Karan Singh
Sky Fox

Tesla has been quietly building something pretty unique on the streets of Hollywood—and we’ve been keeping a close eye on it. That’s right: the long-anticipated Tesla Hollywood Drive-In, Diner, and Supercharger is shaping up to be one of the most creative approaches to EV charging yet.

But this isn’t your average Supercharger site. It features a retro-futuristic, 24-hour diner and an outdoor movie theater, blending the charm of the 1980s with the tech-forward vibe of the 2020s.

Construction has been underway for quite some time, with the Cybertruck-inspired stainless steel structure going up around mid-2024. And more recently, we spotted hints in the Tesla app that the Diner’s debut is getting close.

Diner Controls in App / Car

Tesla hacker Greentheonly managed to spot some new evidence of changes within Tesla’s 2025.8.6 software build, which includes a new modal for “Charger Diner Controls”. While there isn’t anything to activate this new modal just yet, it is an indication of how Tesla intends to integrate the experience right into each and every Tesla.

The text in the modal reads: “Plug in, place your order, recharge” - which means that once you arrive and are plugged in, you’ll be able to place your order - and likely pay through Tesla’s payment system. It seems like this will all be done through either the Tesla app or the vehicle’s tocuh screen. No need to fumble with a separate app or pull out your wallet.

This is definitely a level of integration you just can’t have anywhere else - and just like any other Supercharger site, the Tesla Diner will appear as a suggested site for charging when you’re navigating or looking around the Hollywood area.

45-Foot Screens Ready

Those two absolutely gigantic 45-foot LED screens have now been turned on for the first time, meaning that Tesla is likely close to opening the Supercharger site. The screens were spotted displaying some test patterns, as well as some Tesla-themed content. It really brings the construction site to life - and it's the clearest sign that the Diner is well on its way to completion.

We’re hoping that this first Tesla Diner sees plenty of success - and that Tesla begins opening more of these types of facilities throughout North America, and eventually globally. Given Tesla’s penchant for unique Superchargers, we imagine this could truly be the case one day.

Tesla’s FSD V13 Pushes HW4 Hardware Capabilities; End of Line for HW3?

By Karan Singh
Not a Tesla App

As Tesla continues to push the capabilities of its hardware as it prepares for autonomy with FSD Unsupervised, there has been a distinct divergence in features between HW4-equipped vehicles on FSD V13, and HW3-equipped vehicles on FSD V12.6. 

There are definitely reasons for this, and Tesla hacker Greentheonly, over on X, went into great detail on some of the reasons why this divergence has continued and is likely to continue.

If you’re interested in some background, we recommend the following articles. Although they’re not necessary, you may enjoy reading them before diving right in if you enjoy this topic.

Back in the summer of 2024, we reported that Tesla’s HW4 had yet to reach its full potential, and that HW3 still had some compute to work with. However, FSD has undergone a rapid evolution - there are now fundamental differences driven by the hardware capabilities and sheer scale of the latest builds of FSD.

FSD V13’s Gargantuan Neural Networks

FSD V13 is a substantial leap for Tesla. It features substantially larger neural networks - the core brain that processes all the environmental data and makes decisions. Those networks are far larger in V13 than in V12, which results in a much smoother and human-like expereience.

Tesla’s FSD computers contain two nodes. According to Green’s analysis of FSD V13, Node B, which handles the actual end-to-end driving logic, tripled in size from 2.3 GB in V12 to a staggering 7.5 GB in V13. That’s a substantial increase, and one of the main reasons why HW3 can’t handle FSD V13. While Interestingly, Node A on HW4 remains similar in size to FSD V12, using up about 2.3 GB.

However, this massive size is also pushing the limits of HW4. While this isn’t necessarily a big problem immediately - at the end of the day, there is a limited amount of compute and ram available and model sizes will likely grow in the future. In fact, Tesla is planning to scale model sizes in the next FSD version and has already said they’ll need to optimize them, as context size is limited by on-board memory.

HW3 Limitations

Since HW3 can’t run the latest FSD models, where does this leave millions of Tesla vehicles equipped with the now-legacy FSD hardware? Are they hitting a dead end? Not exactly - Tesla has promised to replace HW3 computers with new units during the Q4 2024 Earnings Call, but only for those who have purchased FSD and only if Tesla is no longer able to update HW3 vehicles.

There’s no doubt Tesla hopes to achieve autonomy and then work backwards to make it compatible with HW3, but that’s unlikely to happen with the limited ram available on HW3.

Tesla’s AI team has continued to say that they’re still working on updating HW3 vehicles - but that they will be taking a backburner to updates for HW4 until the team can optimize the model efficiently enough to run on the smaller footprint. That means V12.6 isn’t just V13 “lite” - it is a distinctly different software branch tailored specifically for HW3’s capabilities.

Green's analysis showed that HW3 under V12.6 runs NNs totaling 1.2 GB on Node A and 3.1 GB on Node B, which is significantly smaller than the footprint of V13. Back in November, we discussed how Tesla is running a smaller and optimized FSD model on HW3, with the specific goal of achieving similar performance to V13. FSD V12.6 appears to be the current implementation of that smaller model strategy.

Green also found that of the total neural nets used for FSD, 135 are shared between the current V12.6 and FSD V13.2 releases, which is the result of Tesla’s AI team working to optimize and refine the V13 model for HW3. So some neural nets are shared between the two sets of hardware, while others are specific to HW3 or HW4.

AI4 in the Future

The fact that V13 is already stretching HW4’s limits makes us wonder about Tesla’s imminent release of AI5. Last year, Tesla mentioned that AI5 would be 18 months away - which is now about 8 months away, and potentially even sooner to help solve the autonomy problem.

At the same time, Tesla is looking to launch Unsupervised FSD in June in Austin, Texas, with presumably HW4, which would indicate that they’re confident in its capabilities.

Unless Tesla launches the Robotaxi network with AI5, we don’t believe AI5 will be a “must have” item. Undoubtedly, it will result in similar improvements to HW4 compared to HW3. However, the software needed to take advantage of the newer hardware could still be years away.

All eyes will be on Tesla’s Robotaxi network launch and the hardware required for it. For now, HW4 owners are in good hands with future updates are on the horizon, and we’re certainly excited for what’s next.
