Analysis: The 2025 Models of Rivian R1T and R1S see improvements in energy usage, coziness, and sustainability

Rivian has revamped its R1T and R1S models' power cells, engines, and chassis design.

In 2021, the R1 series of vehicles will introduce the inaugural use of lithium-iron-phosphate (LFP) batteries.

The redesign could result in the R1 vehicles sharing more similarities with Rivian's forthcoming R2 series.

This week in Seattle, Rivian unveiled its updated R1 series, propelling the brand dedicated to outdoor escapades towards a future of enhanced efficiency and comfort.

Amidst a backdrop featuring the iconic Space Needle, I embarked on a journey to test drive a variety of updated models from Rivian's collection. It quickly became apparent that Rivian has significantly improved these vehicles in numerous aspects. At the same time, Rivian is skillfully navigating the balance of meeting the desires of current R1 owners and luxury electric vehicle enthusiasts, aligning with the forthcoming R2 series expectations, and fulfilling its own requirements to continue thriving as a standalone car manufacturer in the US.

Upon initial observation, the physical form and interior layout of the Rivian R1S electric SUV and the Rivian R1T electric pickup may appear strikingly akin to earlier models. However, a closer examination reveals that almost every aspect, from the internal workings to the technological features, has been upgraded. The underlying framework beneath the exterior has also been modified to enhance the assembly process and to reduce the overall weight.

During a recent visit to Seattle with the Rivian crew, Green Car Reports gained insight into Rivian's methodical approach to addressing feedback. They meticulously improved a vast array of features based on initial customer suggestions and also introduced several innovative elements aimed at attracting new buyers.

The upcoming 2025 models of Rivian's R1T and R1S will come in a variety of battery capacities, namely Standard, Large, and Max options. Additionally, they will be available with two, three, or four motor configurations.

The previous summer saw the introduction of Dual-Motor variants featuring the latest Rivian engines, which are also found in Electric Delivery Vehicles (EDV). Currently, the R1 series is phasing out the old Quad-Motor configuration and introducing a pair of dual-motor modules that come with Rivian's proprietary oil-cooled engines built-in.

The manufacturing process for these engines is geared towards mass production, and indications suggest they could enable the firm to focus more on its compact R2 series. Despite the variety in their configurations, they all utilize identical coils and magnets, and they feature inverter technology developed internally for both front and rear use. Rivian's approach prioritizes the front engines for their energy-saving benefits, whereas the rear engines, which can be disengaged, are intended to boost power.

Rivian has indicated that its latest Tri-Motor vehicles outpace the earlier Quad-Motor variants in terms of speed. The Quad-Motor setups combine two pairs of motors – a smaller set at the front – to produce a total of 1,025 horsepower and 1,198 pound-feet of torque when in launch control mode. This allows them to hit 0-60 mph in under 2.5 seconds, Rivian claims. The Tri-Motor models, however, generate 850 horsepower and 1,103 pound-feet of torque using two rear motors and one at the front, achieving a 0-60 mph sprint in 2.9 seconds. The Dual-Motor versions are divided into standard and performance models. The standard delivers 533 horsepower and 610 pound-feet of torque, reaching 0-60 mph in 4.5 seconds, while the performance version offers 665 horsepower and 829 pound-feet of torque, reducing the 0-60 mph time to 3.4 seconds.

Externally, these versions are almost identical. The Quad-Motor models feature a subtle update with Laguna Blue brake calipers and a discreet "QUAD" insignia centered on their rear emblem. In contrast, the Tri-Motor variants are fitted with yellow brake calipers and a yellow strip on the rear badge.

The configurations for the Tri- and Quad-Motor variants are designed such that the motors at the rear provide additional power, having a higher reduction ratio of 11.7:1 in comparison to the 9.1:1 at the front. During my time testing the Quad-Motor version's launch control on a dragstrip, I noticed that these vehicles accelerate rapidly from a standstill and maintain peak power to a greater velocity than previously possible.

Rivian employs a sophisticated system for controlling the power sent to the wheels, which adjusts based on the selected driving mode. In their 3-motor versions, a pair of motors are installed at the rear, while in the 4-motor versions, motors are placed at both the front and rear without any physical connection, allowing each to independently rotate the wheels they control. The front wheels of the Dual-Motor and Tri-Motor models are powered by a single motor unit that works in tandem with a differential and the application of brake torque. Regardless of the setup, the R1 series vehicles can engage or disengage the motor connection to the front or rear axles to improve either traction or fuel efficiency. Generally, the R1 vehicles prefer to use the front wheels for mild acceleration and typical cruising, only increasing power to the rear motors when additional acceleration is required.

The maximum towing capacities for the R1T and R1S remain unchanged at 11,000 pounds and 7,700 pounds, respectively.

The R1S and R1T models now feature an LFP Standard Pack, along with a more lightweight Large and Max option. Rivian has updated its battery pack structure to be lighter, more cost-effective, and easier to manufacture. Despite these changes, the design continues to use a cooling plate placed between two layers of cells in the Large and Max Packs. The Standard Pack offers 92.5 kWh of capacity, the Large Pack provides 109.4 kWh, and the Max Pack remains at 141.5 kWh.

Rivian has indicated that while the battery capacities for the Standard and Large packs in the upcoming models are not as high as the 2024 versions, the vehicles have enhanced efficiency allowing for a starting range of 258 EPA miles. The Standard Pack variants are anticipated to achieve 270 miles, which matches the range of the first generation's 106-kwh Standard Pack, highlighting the significant advancements in efficiency. Although the range specifications are not yet confirmed, projections suggest that the Dual-Motor R1T with the Max Pack could reach up to 420 miles, and the Dual-Motor R1S with the Max Pack could attain up to 410 miles according to EPA estimates. Rivian is positioning the next-gen R1T as the market's most efficient truck and is eager to validate this claim with actual on-road performance.

The standout selection for aerodynamic efficiency in the range comes from the new 22-inch wheels, not the 21-inch ones. These contribute to an impressively low drag coefficient of just 0.297, which plays a significant role in extending the vehicle's range.

The heat pump has finally arrived for the entire R1 series. This new addition enhances the average real-world driving distance by about 10 miles, and even more in certain conditions. Rivian has taken this opportunity to eliminate the traditional resistive heating system, choosing to use a component that warms up the coolant as necessary and retains that warmth within the system.

Additionally, when taking into account all the enhancements made in terms of efficiency and production processes, it is indicated that the carbon footprint of the R1 has been reduced by 15%.

The bigger capacity options, Large Pack and Max Pack, continue to employ the same 2170-format cylindrical batteries with NCA (nickel cobalt aluminum) composition, but they've managed to increase the energy density by approximately 6%, which offers significant benefits. The much-anticipated LFP batteries feature sizable pouch cells arranged to match the height of the two-tier cylindrical batteries, but they incorporate a completely different cooling system internally. According to what officials shared with Green Car Reports, these LFP batteries have a slightly lower energy density compared to the NCA varieties, and as of now, Rivian has not disclosed the manufacturer of these cells.

Rivian has introduced an updated design for their battery packs, streamlining the previous version to reduce both weight and complexity. The casing of the battery is now created using high-pressure die-casting instead of extrusion, which results in a more precise build and shaves off 55 pounds. Overall, the new battery pack design trims down the weight by 154 pounds, thanks to the consolidation of components like the battery management system into a single unit.

The Gen 2 falls short of expectations

Contrary to prior indications from Rivian, the latest Gen 2 model does not feature the anticipated upgrade to 800-volt technology. Despite previous suggestions from CEO RJ Scaringe that a move to a higher voltage system might occur during the first major update, this has not materialized. Although there have been suggestions that the R1 series is equipped for two-way charging, company representatives have been reluctant to disclose specific details or timelines for this capability.

The process of charging vehicles hasn't seen significant advancements. Although Rivian has managed to broaden and stabilize the duration where charging speed is at its peak, the maximum charging capacity for the larger battery options stays at 220 kilowatts, while the smaller Standard Pack peaks at 200 kilowatts due to its LFP battery cells. According to Rivian, a rapid charge from 10% to 80% could take anywhere between 30 to 41 minutes, varying by battery size, and the vehicles can gain approximately 140 miles of driving distance in roughly 20 minutes. As for Level 2 charging, it caps at 48 amps, equivalent to 11.5 kilowatts, which means that fully charging the largest battery option overnight may not be possible.

The R1 has undergone a significant overhaul of its electrical system, streamlining its complexity and addressing the problem of "vampire drain". This revamp has enhanced efficiency and eased the supply chain process. The electrical framework has been entirely restructured, now featuring a more straightforward configuration with only 7 ECUs, a reduction from the previous count of 17, and eliminating 1.6 miles worth of cabling from the car. Additionally, a new feature is the introduction of a compact DC-DC converter which maintains the 12-volt battery at a stable level of charge and supplies power to low-energy-consuming components such as the entertainment system and lighting.

Nature enthusiasts rely on their vehicle's battery power being just as they left it, and Rivian now boasts the best figures in the industry for power retention when not using Gear Guard, since this feature consumes energy through its camera and computing systems.

Rivian has maintained the vehicle's original design and its distinctive lightning emblem. Indeed, it has accentuated this feature by incorporating active-matrix headlights equipped with adaptive-beam technology, which Rivian plans to activate later in the year. Initially, the lighting will come with adaptive cornering capabilities, while the adaptive high beam is currently undergoing its final certification process and will be activated through an upcoming software update.

The front-end lightbar, along with the updated headlights, is proving to be quite useful. It features 10 separate RGB lighting segments that can display virtually any color, with one of its first functions being to indicate the battery charge level as a percentage. Jeff Hammoud, Rivian's head of design, suggested that the combination of the headlights and the versatile RGB lightbar opens up possibilities for hidden features.

According to Hammoud, the modifications bring a significantly enhanced depth to the overall lighting design. "It retains the unique Rivian identity, which we are fond of," he stated. "Creating a design that is straightforward, easily explainable, and memorable is quite challenging, and we are pleased with it and have no intention of abandoning it."

The R1 line now features an innovative glass roof that can be tinted as desired, accompanied by a versatile interior lighting system that offers a variety of colors.

Rivian has streamlined its user interface to enhance user navigation. To upgrade its graphical displays within the interface, Rivian collaborated with Epic Games using their Unreal Engine. Despite the eye-catching graphics, it still ranks as one of the easiest interfaces to use, particularly for monitoring the status of various car systems.

In addition to the user interface, notable features observed by this reporter are the updated electronic button-operated door openers, which add a touch of opulence, although manual overrides are still available for frequent use. The cabin's refreshed design elements also caught the eye, with a checkered quilt pattern adorning the seating and floor coverings.

The updated Rivian R1 series offers an enhanced driving experience, leaning towards a more luxurious feel, not so much in terms of added amenities but in its smoother ride and superior control.

At that moment, when the Gen 2 starts moving, even in an urban setting, it becomes immediately apparent. Rivian has successfully eliminated the harsh and occasionally loud driving experience of these models by opting for a smoother calibration throughout the range, which maintains the driving dynamics and could even enhance them when the terrain becomes challenging.

The company achieved this by boosting the stiffness of the front springs while decreasing that of the rear springs. They also introduced a revised damping calibration and new bushings. Although all models continue to utilize air springs, the adjustments were made to enhance performance in conjunction with the vehicles' weight distribution and power output, which are concentrated towards the back.

The enhanced performance of the suspension system is highlighted in the Tri-Motor models, which offer unique Rally and Drift modes. During a test run on a slippery, off-road track designed to test the R1S's handling, I noticed a significant variation between the modes, largely attributed to the adjustments made to the hydraulic roll control system.

I had the opportunity to test the R1T's capabilities on a bumpy off-road track, showcasing its impressive wheel movement and trail performance. The R1T boasts a peak ground clearance of 14.6 inches, while the R1S slightly edges it with 14.7 inches. During the test, our R1T's light bar skimmed the surface of the water at the deepest section. With the R1 trucks' ability to traverse approximately 43 inches of water, the heavy rain and deep fords we encountered were no challenge at all.

Enhancements in the Rivian R1: Advanced Integration for Visual and Audio Functions

Rivian has upgraded its sensing and autopilot technology significantly. The newly dubbed Rivian Autonomy Platform integrates 11 cameras, five radar sensors, and sophisticated AI algorithms to achieve a comprehensive 350-degree field of view. This setup boasts camera resolution that is eightfold higher than previous models, which significantly enhances visibility under adverse weather conditions and in poor lighting. Standard configurations of this technology will feature systems to monitor blind spots and assist driving through a combination of lane-keeping and cruise control that adapts to traffic speed. An advanced iteration of this system will also offer driver-activated lane switching and, in the near future, an even more advanced form that has yet to be fully revealed.

Rivian is introducing a high-end sound system featuring Dolby Atmos, which will come with Apple Music built-in, complete with its Spatial Audio feature. For a monthly fee of $14.99, Rivian Connect+ will provide subscribers with Apple Music, the ability to use their vehicle as a wifi hotspot, among other benefits. Additionally, any app compatible with Google Cast can now stream both video and audio content on the vehicle's display, which is especially convenient during times when the vehicle is charging. However, it's important to note that the integration of smartphone interfaces like Apple CarPlay or Android Auto is not available to extend your phone's capabilities into the car's system.

Vehicle owners have the option to unlock their Rivian using Apple Wallet on their iPhone or Apple Watch, or select Google Pixel smartphones. They also have the capability to share their car keys with relatives or acquaintances, or even provide a temporary day pass to access their vehicle.

2025 Range of Rivian R1 Models

Starting this Friday, June 7, Rivian will begin shipping out the latest models of their second-generation R1 series. The 2025 Rivian R1T is set to be priced at $71,700, which includes a $1,800 delivery fee, and the R1S at $77,700. The current range hits its peak with the Tri-Motor Max Pack, which will cost buyers $101,700 for the R1T and $107,700 for the R1S version. Pricing for the Quad-Motor Max Pack models is still to be announced, and these will be released at a later date. Rivian has two trims in the pipeline, the Adventure and Ascend, with the detailed features of each yet to be disclosed. The Dual-Motor and Performance Dual-Motor versions will exclusively come in the Adventure trim, whereas the Tri-Motor and Quad-Motor will be available only in the Ascend trim.

As Rivian approaches the conclusion of its development process for the R2 series—crucial for the company's endurance—the R2 is expected to inherit the motor systems from the R1 series among other features. However, it will also aim to break new ground in making it more economically accessible, profitable, and ensuring the firm's sustained success. Judging by the current progress and its potential implications for the R1 lineup, there's a strong sense of optimism that the company will indeed fulfill these objectives substantially.

Rivian arranged for lodging in Seattle and offered nutritious meals to support the conduct of this review.
