Freightliner LLC has begun to build EPA 2007 emissions-certified heavy-duty Detroit Diesel Series 60 engines for delivery this month. They’re very clean, emitting 95% less particulate matter and 50% less nitrogen oxide than comparable engines in 2006.

Since the development program started in 2004, ’07-compliant Series 60 engines have run over 14 million equivalent miles, the company says, with 2.5 million of them in actual customer vehicles in revenue service. It’s the most thoroughly tested engine and vehicle combination that Freightliner has ever released.

Effective December 29 last year the Detroit Diesel plant in
Redford, Michigan began building engines for some of Freightliner’s largest customers, to be installed in trucks at Freightliner’s Cleveland, NC, Portland, OR, and St. Thomas, Ont. truck plants beginning on January 8,
with initial customer deliveries planned before the end of January. The truck plants had already built a significant number of trucks with pre-production engines so they were ready to begin full production.
