IC Bus, Thor Industries Enter Supply Agreement for New IC Bus TC Series Chassis
New Chassis Gives Customers Flexibility, Outstanding Performance

WARRENVILLE, IL (March 23, 2010) – IC Bus, a wholly owned subsidiary of Navistar, Inc. and the nation’s largest integrated manufacturer of school buses, today announced a new supply agreement with Thor Industries, Inc., the world’s largest manufacturer of recreational vehicles and a major builder of commercial buses.

Through the agreement, IC Bus will be the exclusive provider of mid-size, cut-away chassis to Thor Industries. As a result, Thor Industries’ Champion, ElDorado National, General Coach and Goshen Coach vehicle brands will be built exclusively on the new IC Bus™ brand TC Series chassis.

“The new TC Series chassis is a world-class, top-notch chassis,” said John McKinney, president, IC Bus. “Through this agreement, we’re able to provide Thor Industries and its customer base with a reliable, customer-friendly chassis—along with outstanding service and support—through the largest, most comprehensive dealer network in the industry.”

The TC Series chassis will be powered exclusively by MaxxForce® engines featuring Advanced EGR (exhaust gas recirculation) emissions technology. These engines use an in-cylinder approach to meeting EPA2010 emissions with a goal of providing the most customer-friendly powertrain in terms of fuel economy, performance and overall ownership costs. With MaxxForce Advanced EGR, customers won’t have the worry or inconvenience of finding or filling liquid urea, providing customers with a no-hassle solution that keeps responsibility for emissions compliance with the manufacturer, not the vehicle owner or driver. As a result, IC Bus and Thor Industries are able to deliver high-quality, differentiated products that stand apart from the competition.

“We’re proud to work with IC Bus to deliver customer-friendly products to the market,” said Andrew Imanse, group president, Thor commercial bus division. “This agreement with IC Bus allows us to improve efficiencies, while providing our customers with best-in-class chassis and engine technologies.”

The TC Series chassis is available to customers in the United States and Canada and is supported by the IC Bus™ dealer network, the largest bus dealer network in North America.
