Cummins splits with Navistar over SCR choice

Christopher Goodfellow - 24 March 2010

Navistar will no longer offer Cummins engines because of its decision to use Selective Catalytic Reduction (SCR) in its 2010 models.

Cummins president, Rich Freeland, said SCR was the right choice to meet the new EPA regulations, regardless of this development:

"In each emissions cycle there's a decision: can you stretch and get a little more out of the technology you've got? Our conclusion was that trying to stretch some more out of the 2007 technology was going to have a very negative impact on our customers, so we made the decision to move to the new technology."

At the Mid-American Trucking Show a Cummins spokesperson said the manufacturer had already sold 2,500 EPA2010 engines.
