Rivian has officially launched the next-generation R1S and R1T, new versions of the company’s flagship electric vehicles.
“We continue to evolve our flagship R1 vehicles,” CEO RJ Scaringe said, “offering quality and performance without compromise. Our revamped R1S and R1T push the technical boundaries further, creating our most capable products to date.”
Rivian aimed to refine and improve performance, design, range, and overall ownership experience with the new R1T and R1S, bringing everything from new drivetrains to new interior aesthetics to the EVs without compromising any of the features that owners loved about the first generation.
Additionally, Rivian is rolling out its new Autonomy Platform, which was developed in-house and utilizes eleven internally developed cameras along with five radars that perform over 250 trillion operations per second.
“For most owners, their R1 Gen 2 will be the most powerful computer that they own,” VP of Autonomy and AI for Rivian, James Philbin, said.
Let’s dive into some of the improvements Rivian has employed:
Performance
Rivian’s next-gen R1 platform now features more power, performance, and range, all stemming from a new drive unit offered in its Tri and Quad-Motor configurations. Dual-Motor has not gone anywhere either, and still offers great performance metrics:
- Dual-Motor Our Dual-Motor delivers incredible all-wheel drive capability along with 665 horsepower and 0–60 mph in as quick as 3.4 seconds for the Performance variant
- Tri-Motor Our all-new 850 horsepower Tri-Motor packs two motors in the rear and one in front for a blend of exceptional power and range. The Tri-Motor R1T delivers 0–60 mph in 2.9 seconds while offering an estimated range of 380 miles. In Conserve Mode, the estimated range is up to 410 miles.
- Quad-Motor For peak adventure, our new 1,025 horsepower Quad-Motor delivers 0–60 mph in less than 2.5 seconds in R1T — and ¼ mile in 10.5 seconds — with a staggering 1,198 lb-ft of torque when using Launch Mode. 60–80 mph acceleration is 1.5 seconds, with incredible torque control at each wheel for superior on-road performance and off-road capability.
Ride and Handling
Rivian also focused on the ride and handling experience in the R1 lineup for this second-generation vehicle launch. The suspension system has been fully re-engineered, improving on what customers called a “sport-tuned feel” in the first-generation EVs. Rivian decided to go with a “smoother” ride for the new R1T and R1S, which is adjustable to ensure comfortable on and off-road capabilities.
Vehicle equipment has also been refined. Rivian developed new wheels and fitted them with new tires, including a redesigned 22″ aerodynamic wheel design and Pirelli-developed tires to increase range.
For Performance, Rivian is going with an Ultra-High-Performance Michelin tire that will be available on the Quad-Motor configurations. Additionally, for a “well-rounded” experience, Goodyear has a 20″ ADV tire that offers “balanced all-around capability with the rolling-resistance of an all-season,” and comes standard.
Range and Batteries
Three battery pack sizes will still be offered by Rivian, but the Max and Large batteries have been completely re-engineered and offer ranges of 420 and 330 miles, respectively, based on estimations. They will continue to use 2170 cylindrical cells, and the pack enclosure features a “large high-pressure de-casting” system to simplify manufacturing and reduce mass.
The new Standard Pack will feature lithium-iron-phosphate (LFP) chemistry and provide an EPA-estimated 270-mile range.
140 miles of range can be regained in as little as 20 minutes and are compatible with all major public high-speed charging networks. This includes the Rivian Adventure Network and the Tesla Supercharger Network.
Design and Experience
Rivian honed in on new features with the R1T and R1S and also added two new premium interiors, new exterior paint options, and new darkout trim options.
These are in addition to the new wheel and tire choices, and now vehicles come with a new electronically tinted glass roof, new in-cabin storage, interior lighting themes, new digital interfaces, and new cell shading designs for the different drive modes. It has also improved on the wireless charger.
Surround Sound Audio with Dolby Atmos is available with Rivian Premium Audio.
Refined Electrical Architecture and Compute Platform
The second-gen R1 features new electrical architecture and a new compute platform that was developed in-house by the Rivian hardware and software teams.
“While the exterior of the R1 looks similar, the electrical system is completely redone, providing a significant increase in features as well as a dramatic increase in sensing and compute capability,” Rivian’s SVP of Electrical Hardware, Vidya Rajagopalan, said.
Trimming the ECU count from 17 in the first-gen to just 7 in the second-gen, the “massive simplification” was part of a shift in zonal architecture. Infotainment, autonomy, and vehicle access, as well as battery management, all have their own ECUs. Every other vehicle function is controlled by the remaining three.
Rivian Autonomy Platform
The Rivian Autonomy Platform utilizes “11 internally developed cameras and five radars performing over 250 trillion operations per second, an industry-leading level of compute power.”
The cameras are high-resolution and now include 4K HDR units, which have 360-degree visibility and can see three-times farther than the previous system, as well as 10 seconds ahead at highway speeds.
These are the most camera megapixels of any EV in North America and enable improved dynamic range and clear vision in high-contrast scenarios, like tunnel entrances and exits.
Rivian is also utilizing a cabin-facing camera in the rearview mirror to detect both driver fatigue and distraction when operating in Enhance Highway Assist mode, which will roll out later this year.
The Autonomy Compute Module is backed up by dual NVIDIA DRIVE Orin processors, delivering 10 times more compute performance than the previous system.
Pricing
The new R1S will start at $75,900 and the R1T at $69,900. Dual-Motor configurations can be ordered today and are available immediately. Tri-Max is expected to be launched in the late Summer, while Quad Max will come shortly after.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
