Reimagining the Rivian R1T and R1S: A Second Generation Rebirth
Suspension and Handling Upgrades
The second generation of Rivian’s electric vehicles, the R1T and R1S, have undergone significant changes to their suspension and wheel and tire packages. The R1S, in particular, has seen larger modifications to its spring rates, damper rates, and bushings, all aimed at providing a smoother and more comfortable ride. Even in off-road conditions, such as when traversing water or navigating rocky terrains, the R1S impresses with its quiet and comfortable performance. The all-wheel drive system proves to be intuitive and responsive, offering a natural and confident driving experience.
Innovative Electrical Systems
Rivian has revolutionized the electrical systems of the R1T and R1S in their second generation. The vehicles now feature a zonal architecture that reorganizes and reduces the network of wire harnesses and modules required for various systems. This architectural redesign eliminates an impressive 1.6 miles of wire, weighing around 44 pounds of copper. The result is a more efficient and streamlined electrical system that enhances overall performance.
Immersive Visual Experience
The second generation of Rivian’s electric vehicles introduces a software overhaul that includes a visual upgrade. The previous realistic graphics have been replaced with real-time 3D graphics featuring a cell-shaded, cartoony style. As drivers switch between different drive modes, they will experience animated transitions that immerse them in various environments. This visually stunning upgrade adds a touch of excitement to the driving experience.
Unleashing Power on the Racing Strip
Rivian surprised testers with a trip to a racing strip to demonstrate the acceleration capabilities of the R1T and R1S. Equipped with quad motors and super sport summer tires, the vehicles showcased their impressive performance on a prepared surface. In a short zero to 60 mph test, the R1T achieved a remarkable time of 3.22 seconds, while the R1S completed a quarter-mile run in just 11.14 seconds. These impressive acceleration figures rival those of sports cars, highlighting the versatility and power of these electric utility vehicles.
Meticulous Attention to Detail
Although the second generation of Rivian’s electric vehicles may appear similar to their predecessors, the company assures us that virtually every aspect of these vehicles has been touched upon. With over 600 new parts, Rivian has made extensive improvements to the powertrain, battery, interior features, and dashboard. These upgrades may not be immediately visible, as they are largely hidden beneath the unchanged body and sheet metal. However, owners of the second-generation R1T and R1S can expect enhanced electric motors, ranging from 533 to a staggering 1025 horsepower and up to 1198 pound-feet of torque for the top-spec quad motor setup.
Extended Range and Charging Capabilities
Rivian has also addressed the range and charging capabilities of its electric vehicles. The second generation features new battery technology with more energy-dense cylindrical cells for the large and max batteries. Additionally, a new prismatic cell lithium iron phosphate pack has been introduced for the standard setup, aimed at providing a cost-effective option for entry-level models. Depending on the chassis (T or S), battery choice, powertrain configuration, and wheel and tire package, the R1T and R1S boast an estimated range of 258 to 420 miles. Fast charging remains a priority, with Rivian supporting both native CCS ports for DC fast charging and Tesla’s NACS charging via an adapter.
Enhanced Safety and Lighting Features
Rivian has not overlooked safety and lighting features in its second-generation models. The front and rear light bars have been updated with new RGB LED segments that animate during charging and can even indicate the direction to pass when hazard lights are activated. The headlights now feature digital matrix projection, allowing certain zones to be partially dimmed to avoid dazzling oncoming traffic. Although this feature will require a software update later in the year, it showcases Rivian’s commitment to safety and innovation.
In Conclusion
The second generation of Rivian’s electric vehicles, the R1T and R1S, represents a remarkable rebirth for the brand. With extensive upgrades to suspension, electrical systems, performance, range, and safety features, these vehicles offer an impressive driving experience. Rivian’s dedication to innovation and attention to detail is evident in the numerous improvements made to every aspect of the vehicle. Whether tackling off-road terrains or accelerating on a racing strip, the R1T and R1S showcase the power and potential of electric utility vehicles.
