TENNECO AUTOMOTIVE TECHNOLOGIES FEATURED ON 2006 HUMMER H3

Company Launches New Incremental Business On New HUMMER Model

LAKE FOREST, ILLINOIS, SEPTEMBER 22, 2005 - Tenneco Automotive (NYSE: TEN) today announced several automotive technologies on the HUMMER H3 including the ride control, elastomer and exhaust components.

"We're pleased to showcase our cutting-edge technologies on the new HUMMER H3," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "Our relationship with General Motors remains strong, and we look forward to providing state-of-the-art engineering and manufacturing capabilities to new vehicle programs such as the H3."

The midsize H3 was designed to achieve extreme off-road performance with comfortable on-road capability, and Tenneco Automotive's monotube shock absorbers, derived from those utilized on GM's full-size trucks, are a key aspect of the H3's chassis system. The monotube design separates the gaseous chamber from the oil, enabling smoother and more precise response.

Tenneco also supplies the exhaust system for the midsize H3, which comprises a catalytic converter assembly, lightweight spun resonator and transverse muffler; all designed for the rugged off-road requirements the H3 demands. The spun resonator features a low-backpressure, lightweight and durable design, and marks the first time GM has incorporated this technology onto one of its vehicle platforms.

In addition, a number of Tenneco's elastomer products are featured on the H3. They include:

  • Leaf spring and shackle bushings;
  • Front and rear stabilizer bar bushings featuring SLE™ technology;
  • Cross member and lower control arm bushings.

These components provide superior NVH performance for everyday road conditions while also increasing ground clearance and wheel articulation needed for off-road performance.

Tenneco is a global supplier to General Motors, providing both ride control and exhaust components for GM passenger cars and light and medium-duty trucks.

Tenneco Automotive is a $4.2 billion manufacturing company with headquarters in Lake Forest, Illinois and approximately 18,400 employees worldwide. Tenneco Automotive is one of the world's largest designers, manufacturers and marketers of emission control and ride control products and systems for the automotive original equipment market and the aftermarket.
