Citroën's 'Kinetic' RFS suspension system

US company Tenneco Automotive is trumpeting the role of its patented 'Kinetic' reversible-function stabiliser suspension in winning the Manufacturers title in the 2003 World Rally Championship

Citroën's 'Kinetic' RFS suspension system

The RFS system is designed to offer improved stability and driveability through 'mode decoupling' - an inherent ability to distinguish between roll motion and articulation motion. Tenneco engineers based in Brussels, Belgium, worked with to refine it for the Xsara WRC.

Citroen Sport has an exclusive licence to use the 'Kinetic' RFS system in the championship and has employed the technology on all its Xsara WRC cars. It is said to give them more evenly distributed wheel loading, more consistent handling and improved traction, allowing the drivers to attack with confidence over all surfaces.

The system passively interconnects the front and rear suspension systems in order to optimise suspension performance in both on-road and off-road environments. Its first production application will be on the 2004 Lexus GX470 SUV. Toyota will offer a version of the technology as an option through a licensing agreement with Tenneco.
