COLUMBUS, Ind. (April 4, 2002) -

Today Cummins Inc. (NYSE: CUM) announced that it has shipped the first of its on-highway engines certified by the Environmental Protection Agency (EPA) to the 2.5-gram NOx + NMHC standard.

The first engines were shipped to International Truck and Engine Corporation. Cummins will continue to manufacture and deliver a limited number of engines certified at the new standards to its OEM partners over the next few weeks, as part of a managed introduction ramp-up plan.

"We have been able to ensure that the engines we produce are thoroughly tested and integrated into OEM vehicles as a result of our close working relationships with OEM partners and our consistent product strategy," said Ed Pence, Cummins Vice President - Automotive Business. "By providing certified engines at this time, we will ensure our customers get a quality product."

Cummins introduced a full product line of on-highway engines beginning in1997 that were designed to work with cooled Exhaust Gas Recirculation (EGR) and began field testing the engine subsystem in December, 1999. By October of this year, Cummins will have accumulated over six million miles of on-highway vehicle field-testing and 115,000 hours of laboratory tests with the ISX engine alone, and two-three times that amount with its full line of on-highway products.

"Our customers want products that are thoroughly tested in real-world conditions. We are meeting this objective," said Tom Kieffer, Cummins Executive Director - Marketing. "We are the first in the industry to certify an engine because we want customers to have confidence in our ability to meet the standards with a product that performs better than today's products."
