EDENKOBEN, Germany, October 24, 2006: Tenneco Inc., manufacturer of Walker® aftermarket exhaust systems and catalytic converters and Monroe® shock absorbers, has joined the EcoFuel World Tour, the first round-the-world tour using a vehicle powered by natural gas.

A four person team led by Rainer Zietlow, a German driver who set a new high altitude World Guinness Record for passenger cars on the slopes of the volcano Ojos Del Salado on the Chilean-Argentinean border, will drive a Volkswagen Caddy EcoFuel on a 50,000 km tour starting on October 23 in Hanover. The team will stop at Tenneco's European emission control engineering and manufacturing headquarters in Edenkoben on October 24 before continuing its tour through Europe, Asia, Oceania, South and North America it its attempt to reach a new Guinness World Record. The EcoFuel World Tour will donate 10 eurocents per kilometer driven to the international charity organization SOS-ChildrenVillage*.

As a global supplier of advanced original equipment and aftermarket emission control products designed to reduce pollution, we are extremely proud to be part of this important environmental and

charitable initiative with our Walker® aftermarket emission control brand,” said Alex Gelbcke, Vice President Aftermarket Europe.

Tenneco supplies the rear exhaust system and its advanced Position Sensitive Twin System (PST) shock absorbers as original equipment on the VW Caddy. The PST shocks are particularly suited to the EcoFuel initiative given the loading on the vehicle which, in addition to its standard four natural gas tanks, will carry additional gas tanks in the trunk meaning that the weight in the vehicle will be subject to constant change as the gas tanks are emptied and replenished. The PST shocks adjust to various vehicle loads, making them ideal for vans wherein heavier loads require a higher damping value to deal with larger mass while avoiding a harsh ride at lower loads. These provide soft damping for straight line driving to provide maximum driver and passenger comfort and higher damping values during braking and cornering to improve ride handling and safety. The Tenneco rear exhaust system on the VW Caddy ensures a continuous, smooth flow of exhaust gases out of the engine, improving engine performance while reducing drive-by noise.

The company's commitment to reducing pollution is evidenced by the Walker® brand which developed the world's first catalytic converter in 1963. Tenneco has continued to pioneer catalytic converter technology for both the vehicle manufacturers and the aftermarket ever since. Its catalytic converters meet the toughest EU standards and can reduce harmful emissions by up to 99%. Catalytic converters oxidize harmful hydrocarbons and carbon monoxide into harmless water and carbon dioxide, and reduce harmful nitrogen oxides into harmless nitrogen.  The efficiency of catalytic converters, combined with improvements in the quality of fuels, means that it would take up to 100 new cars to produce the same emissions as just one car made 20 years ago. These reductions are of significant benefit to human health – the pollutants are known to contribute to respiratory irritation and impaired vision, for example – and also to the environment, as these harmful emissions are factors in acid rain and global warming. Although emissions from natural-gas combustion systems are less than with petrol or diesel fuel, a catalytic converter remains a necessity.

To further reduce emissions from diesel fuel, Tenneco also recently introduced its new Walker® aftermarket Diesel Particulate Filter (DPF) to reduce particulate emissions on older-generation diesel vehicles. The Tenneco Walker® DPF features an innovative lightweight foam filter coated with precious metals and combines the catalytic converter and DPF into one unit. Tenneco was one of the first global suppliers to offer both additive and catalyst-coated diesel particulate filter technologies in series production for Europe's vehicle manufacturers.  It first began production of OE diesel particulate filter technology in 2000 in conjunction with PSA Peugeot-Citroën for the Citroën C5 and Peugeot 406 diesel passenger vehicles. Today the company supplies DPF for DaimlerChrysler's Mercedes-Benz C-Class, E-Class and CLK passenger cars, Jaguar S-Type, VW Sharan and the Audi A6 and A4. The company also continues to supply PSA on its new Peugeot 407, Peugeot 807, Citroën C5 and C8, Fiat Ulysse and Lancia Phedra models.

 “Our experience in designing and manufacturing exhaust and suspension systems for volume vehicle production for the world's car manufacturers provides unique insight when supplying the replacement market with Walker®-branded exhaust components that improve a vehicle's environmental performance and Monroe®-branded shock absorbers that can reproduce the original vehicle dynamics,” Gelbcke added.
