As expected, automotive industry light vehicle production recovered significantly during 2011, and we successfully leveraged our strong position on leading vehicle platforms to deliver record revenue growth across a balanced mix of customers and platforms. We’re proud to be on some of the world’s top-selling vehicles and, in 2011, we continued to launch and win new OE business, with 128 new or replacement platforms awarded.
Commercial Vehicles Our full suite of emission control solutions for commercial vehicles remains a key growth driver for Tenneco. Increasingly stringent regulations for diesel particulate and NOx are being implemented for both on- and off-road vehicles used in a variety of applications ranging from agriculture to mining to construction. Tenneco’s emissions technology roadmap is aligned to global emissions regulations, which enables us to provide customers the right solution for any engine size or powertrain strategy.
In 2011, our OE commercial vehicle revenue increased by 61%, mostly driven by launches with our North American customers. Going forward, this business will become geographically diverse as vehicle programs launch in South America, Europe, Japan, South Korea and China. Given the continuing adoption and enforcement of diesel emissions regulations, the strength of our technology and the depth of our application engineering expertise in this area, we expect significant growth in our commercial vehicle business.
Advanced technology and engineering expertise differentiate our products and drive growth for Tenneco in our ride control business as well. Our innovative electronic damper technologies target the entire spectrum of light vehicles—from high-end luxury vehicles to smaller city vehicles—helping OEMs achieve the correct balance of comfort and control for each application. We continue to win new business for our Continuously Controlled Electronic Suspension (CES) technology, and launched the system on three new models during the year. At the end of 2011, Tenneco’s CES systems could be found on 33 different production models, and in development for eight additional models.
