Cummins Inc. (NYSE:CUM) has reached an agreement with American Freightways Inc., the Harrison, Ark.-based less-than-truckload carrier, to initiate a low-NOx (nitrous oxide) engine recalibration program using technology developed by Cummins, the world's largest producer of commercial diesel engines above 50 horsepower.

To meet its goal of reducing emissions without sacrificing engine performance or fuel economy, American Freightways is recalibrating the portion of its fleet of tractors containing 1,500 Cummins 1997 and 1998 M11 and M11 Plus engines. Under this initiative, American Freightways expects to recalibrate these engines by spring of 2002.

"American Freightways strives to stay at the forefront of leading-edge technology - to provide excellent service to our customers and to do the right thing for the environment," said Dan Umphress, vice president of fleet maintenance. "Now Cummins is providing American Freightways with the right technology at the right time to produce fewer emissions in our M11 and M11 Plus engines, without sacrificing performance or fuel economy."

The recalibrations take place at regular maintenance intervals, utilizing Cummins INSITE(TM)/ESDN software as a tool for initial recalibration, and later utilizing Cummins INSPEC(TM) software as a management tool to adjust and maintain engine parameters.

Cummins is providing American Freightways with recalibration software, as well as engine stickers for each recalibrated engine to indicate that it meets the optional low-NOx standard set by the EPA.

"We are pleased to announce that we are working closely with American Freightways, a long-time Cummins customer, to recalibrate this company's fleet of Cummins M11 and M11 Plus engines," said Tom Kieffer, executive director - marketing at Cummins. "American Freightways has always enjoyed a reputation for going above and beyond what is required by its customers and by the EPA. To their credit, they are among the first of our customers to take this step toward a cleaner environment."

American Freightways, recently acquired by FedEx Corporation, is a scheduled for-hire carrier of less-than-truckload shipments providing direct all-points delivery service in 40 contiguous states. Together with Viking Freight of San Jose, Calif., these two operating companies of FedEx Freight provide direct service to virtually all U.S. zip codes, including Alaska, Hawaii and Puerto Rico. Internationally, American Freightways and Viking provide service to North, Central and South America, and the Caribbean. More information about AF can be found at www.AF.com.
