Recently, we had the opportunity to visit the Rivian’s R&D center in Palo Alto, California, where we were granted an exclusive behind-the-scenes look at the latest advancements in the Rivian R1S lineup. At the heart of our visit was the highly anticipated Generation 2 Tri-Motor R1S, a vehicle that promises to redefine the premium SUV experience.
Streamlining the Architecture: Simplicity and Efficiency
One of the most striking aspects of the Gen 2 R1S is the significant simplification of its underlying architecture. As RJ Scaringe, Rivian's Founder and CEO, explained, the team has taken a meticulous approach to consolidating the vehicle's electronic control units (ECUs) from 17 down to just 7. This remarkable feat of engineering not only reduces the overall wiring harness but also simplifies the printed circuit board assemblies (PCBAs) throughout the vehicle.
"We took 17 ECUs and consolidated that down to 7 ECUs," Scaringe noted. "This complete re-architecture saves us a tremendous amount of both wiring harness and obviously simplifies all the PCBAs."
The benefits of this streamlining are multifaceted. Not only does it reduce the overall complexity of the vehicle, but it also translates to tangible cost savings and improved software updateability. As Scaringe emphasized, "This is really an important vehicle for us because it introduces this whole new vehicle architecture, which enables us to have big cost savings but makes it easier to do software updates with over-the-air updates."
Powertrain Enhancements: Tri-Motor Perfection
Stepping inside the Gen 2 R1S, one of the most notable changes is the introduction of the Tri-Motor configuration. Rivian has strategically positioned this powertrain option as the "Goldilocks" solution, striking a balance between the raw power of the Quad-Motor and the efficiency of the Dual-Motor setups.
"The Tri-Motor will do 0 to 60 in just under 3 seconds, close to 850 horsepower," Scaringe revealed. "But you know, just a beautiful drivetrain both the front and the rear drive unit now completely in-house."
The decision to develop the Tri-Motor in-house was a deliberate one, as Rivian sought to optimize the performance and efficiency of this critical component. As Scaringe explained, "We've really done a lot of work on simplifying the drive units, and I tore to pieces and had a look at, and I mean that was a big change from the previously store-bought version."
The Tri-Motor's performance capabilities are complemented by its impressive range. With an EPA-certified range of 371 miles, the vehicle strikes a balance between power and efficiency. Scaringe noted that in "conserve mode," the Tri-Motor can achieve up to 400 miles of range, thanks to its dynamic rear disconnect feature that disengages the rear motors when not needed, further enhancing efficiency.
Interior Refinements: Elevating the Premium Experience
As we explored the interior of the Gen 2 R1S, it was evident that Rivian has paid meticulous attention to the details. The cabin has been meticulously crafted to deliver a premium, cozy, and personalized experience for the driver and passengers.
The new Sky interior features a warm, open-grain walnut wood finish, complemented by a softer, more inviting seat design. Scaringe highlighted the thoughtful touches, such as the matching pattern on the floor mats, grab handles, and even the back of the seats, creating a cohesive and visually appealing aesthetic.
One of the standout features is the PDLC (Polymer Dispersed Liquid Crystal) roof, which allows the occupants to control the opacity of the glass, transitioning from transparent to opaque with the touch of a button. This innovative feature not only enhances the cabin's ambiance but also provides a practical solution for managing glare and sunlight.
Rivian has also made subtle yet impactful improvements to the rear seating area, such as the repositioned cup holders and the addition of a new storage bin. These thoughtful enhancements demonstrate the company's commitment to continuously refining the user experience based on customer feedback.
Suspension and Ride Quality: Striking the Perfect Balance
As we took the Gen 2 R1S for a test drive, the vehicle's refined suspension and ride quality immediately stood out. Scaringe explained that the team has made significant changes to the rear dampers and bushings across the entire vehicle, resulting in a smoother and more comfortable ride without compromising the dynamic capabilities.
"We redid the rear dampers, and we also redid the bushings across the whole vehicle, so just soften the ride," Scaringe said. "We still can go dynamic, we can dynamically change it to be stiff, but we felt the sort of general purpose, what we call all-purpose mode, was still a little too stiff on the first-gen vehicle. So second-gen, we wanted to soften things up, and that's feedback we got from customers as well."
The improved suspension tuning, combined with the vehicle's robust and secure handling, creates a driving experience that is both comfortable and confidence-inspiring, even on less-than-perfect road surfaces.
Autonomous Driving Capabilities: Seamless Integration
One of the standout features of the Gen 2 R1S is its advanced autonomous driving capabilities. During our test drive, Scaringe demonstrated the vehicle's self-driving mode, which allows the driver to take their hands off the wheel and let the vehicle handle the driving tasks.
"If you just double-tap here, it'll take over, and you can go hands-off completely," Scaringe explained. "It'll prompt you after about 20-30 seconds, depending on the road, but you can increase the speed, and it'll stay in the mode."
The R1S is equipped with an impressive array of sensors, including 55 megapixels of camera coverage and five radar units, including imaging radar in the front. This advanced sensor suite, coupled with Rivian's robust computing platform, enables the vehicle to navigate a wide range of road conditions and construction zones with confidence.
As Scaringe noted, "If there's a circumstance, let's say a construction zone or if we're on a road that we haven't validated on to say that we're comfortable with you driving itself, it'll say, 'Oh, maybe that's what it is,' and it'll disengage."
Optimizing the Supply Chain: A Holistic Approach
Rivian's commitment to innovation extends beyond the vehicle itself, as the company has also taken a proactive approach to optimizing its supply chain. Scaringe revealed that the team has renegotiated more than 50% of their supplier contracts, driven by both part design changes and a desire to work with suppliers that offer better cost structures and quality.
"A huge renegotiation, and some of that was because part design changed or the system design changed, but other areas it was because we wanted to work with a different supplier, better cost structure, better quality," Scaringe explained.
This strategic focus on the supply chain aligns with Rivian's broader vision of sustainability and responsible manufacturing. By carefully selecting suppliers and optimizing the supply chain, the company aims to reduce its environmental footprint and ensure the long-term viability of its operations.
Expanding Horizons: Rivian's Global Ambitions
As Rivian looks to the future, the company has its sights set on expanding beyond the North American market. Scaringe shared that the Gen 2 R1S platform is being designed for both the US and European markets, with plans to initially export the vehicles to Europe before eventually localizing production.
"R2's being designed for us and Europe from the get-go, and we'll be building them first in Normal, [Illinois], and then we have another plant we're building just outside of Atlanta, [Georgia], and initially export, but long-term, we know because of tariffs, it'll be something we'd want to localize to Europe," Scaringe said.
This global approach aligns with Rivian's mission to make its innovative electric vehicles accessible to a wider audience. By tailoring the R2 platform to the unique needs and preferences of the European market, the company aims to capture a significant share of the growing EV demand across the continent.
Rivian's Collaborative Partnerships: Powering the Future
In a strategic move, Rivian has also forged a collaboration with Volkswagen Group, leveraging its software stack and electronic architecture to power a range of VW Group brands, including Porsche and Audi. This partnership represents a significant opportunity for Rivian to expand the reach of its innovative technology beyond its own vehicle lineup.
As Scaringe explained, "The deal we just announced, it's a $5.8 billion deal, and it's taking our software stack and the electronics, not including our self-driving platform, but the electronics and software outside of self-driving, and we're going to be deploying it across a whole host of brands under the VW group portfolio."
This collaboration not only provides Rivian with additional revenue streams but also allows the company to contribute its expertise to the development of highly compelling electric vehicles across multiple brands and price points. By leveraging Rivian's technology, the Volkswagen Group can accelerate its own electrification efforts, ultimately benefiting consumers and driving the widespread adoption of sustainable mobility solutions.
