Advanced Suspension System Enhances Vehicle Stability and Handling

LAKE FOREST, ILLINOIS - BRUSSELS, BELGIUM, November 14, 2003 - The Xsaras that gave Citroen the Manufacturer's title in the World Rally Championship, one of the world's most demanding motorsports competitions, set itself apart from the field with patented Kinetic® technology provided by Tenneco Automotive (NYSE: TEN).

In the rigorous on- and off-road conditions of the World Rally Championship (WRC), the Kinetic technology gave the Citroen team more even wheel loading, consistent handling and improved traction, allowing the drivers to attack with confidence over constantly changing surfaces ranging from dry pavement to snowy gravel. The Citroen team has an exclusive license to use the Kinetic RFS system in the World Rally Championship and has employed the technology on all entries since the highly successful technology debut in Monaco where the Citroen cars took all three podium places.

"The Citroen team's success highlights the outstanding performance of our Kinetic technology, which provides the best of both worlds in terms of comfort and handling," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "We are very excited that our breakthrough Kinetic advanced suspension has helped the Citroen team to succeed in this prestigious international race competition."

Tenneco Automotive's Kinetic Suspension System is designed to offer vehicle stability and improved drivability through a principle called mode decoupling - the system's inherent ability to distinguish between roll motion and articulation motion. This capability enables the vehicle designer to increase the vehicle's roll stiffness to reduce body roll and improve handling, without the typical trade-off of ride comfort degradation. The system passively interconnects the front and rear stabilizers of the vehicle in order to optimize suspension performance in both on and off-road environments. On road, the system's greater roll stiffness delivers crisper handling when needed, while at the same time provides a smoother ride over bumpy road surfaces. More challenging off-road driving is also easier and more comfortable with the Kinetic system due to enhanced wheel travel and articulation freedom.

Tenneco Automotive engineers worked directly with Citroen's chassis engineers to develop the system for racing, which can also be adapted to meet the ride and handling demands of on-road consumers.

"One of the Xsara's strong points is its capacity to adapt quickly from one terrain to another," said driver Sebastien Loeb, who took a solid second place in the final event to secure the championship for Citroen. "Its balance is simply remarkable."

The advantages provided by the Kinetic system in competition use are equally appropriate for passenger car use. The system works without sensors, pumps or valves - a simple passive system that can be easily introduced to enhance the performance of any vehicle.

"We are also bringing this technology to our customers so they can offer the same comfort and handling benefits that the Xsara drivers experienced in the World Rally Championship," Frissora said.

The first production use of the Kinetic Reversible Function Stabilizer suspension technology will be on the 2004 Lexus GX 470 sport utility vehicle. Toyota is offering a version of the technology as an option on the SUV through a licensing agreement with Tenneco Automotive.
