A Detailed Look at the R1S Rear Suspension and CFRP Components

:hammer_and_wrench:The R1S rear suspension features a rear cradle with two large castings and cross-car connections. This design provides stability and control during cornering and off-road driving.

:weight_lifter:The suspension system utilizes air over hydraulic setup, which allows for independent control of each wheel and eliminates the need for sway bars. This improves handling and articulation.

:nut_and_bolt:The R1S rear suspension uses forged components and high-quality manufacturing methods to ensure durability and performance. This results in a premium and robust suspension system.

:battery:The quad motor setup of the R1S enables maximum length and equal length CV axles, providing excellent power distribution and control. This setup is ideal for off-road and high-performance applications.

:checkered_flag:The rear suspension of the R1S is designed to offer exceptional ground clearance and travel, making it suitable for off-road adventures. The suspension geometry and components are optimized for maximum performance and efficiency.

What is the advantage of using CFRP in the rear suspension?

—CFRP (carbon fiber reinforced plastic) offers a high strength-to-weight ratio, which allows for lighter and stronger components. This results in improved performance, efficiency, and durability of the rear suspension system.

How does the air over hydraulic setup improve handling?

—The air over hydraulic setup allows for independent control of each wheel, which eliminates the need for sway bars. This improves handling by reducing body roll and optimizing traction and stability in various driving conditions.

Why is the quad motor setup beneficial for the rear suspension?

—The quad motor setup enables maximum length and equal length CV axles, which improves power distribution and control. This setup is ideal for off-road and high-performance applications, as it provides excellent traction and maneuverability.

What makes the R1S rear suspension suitable for off-road adventures?

—The R1S rear suspension offers exceptional ground clearance and travel, allowing the vehicle to navigate rough terrains with ease. The suspension geometry and components are optimized for off-road performance, ensuring maximum traction and stability.

Is the R1S rear suspension compatible with other Rivian models?

—Yes, the R1S rear suspension is similar to the rear suspension of the R1T and other Rivian models. It features similar design principles and components, which provide consistent performance and handling across the Rivian lineup.
