Rivian to update R1T and R1S suspension with McLaren supplier

19 December 2022

Rivian will update the suspension on both the R1S and R1T to the latest Monroe CVSA2/KInetic H2 solution from Tenneco. The company is supplying McLaren with its sophisticated racing setup and the updated solution for Rivian is meant to not only improve handling but reduce noise at the same time.

The CVSA2/Kinetic has been originally designed for sport and hypercar models but Tenneco has upgraded its components and made it available for off road vehicles as well - hence the H2 moniker. The system provides continuously controlled damping and removes the need for anti-roll bars by replacing them with hydraulic roll control.

No sway bars means less weight, less road noise and better control, in many situations it actually means better contact between the tire and the road. It means that vibrations from one wheel are not transferred to the other or to the vehicle itself making the ride smoother and much quieter.

The latest solution from Tenneco has been specifically modified for use on electric cars and it has a minimal impact on the vehicle’s range since it is consuming very little energy. The H2 version offers hydraulic roll control while the X2 version offers both roll and pitch control. The CVSA2 has two solenoid valves to offer independent compression and rebound damping control for ultra-fast reactions.

To complete the new setup, Rivian will use the latest Clevite Elastomer suspension bushings and mounts from Tenneco as well. It means that future Rivian trucks will handle even better than the current ones and will be quieter at the same time which is hard to believe sometimes - how much more quiet can electric cars get?
