Many of the trucking industry’s major equipment makers in 2005 began introducing new engines designed to meet the stricter emissions standards taking effect in January 2007.

Volvo Trucks North America Inc. and sister company Mack Trucks Inc. both unveiled new proprietary engines geared to the upcoming regulations. Volvo planned to replace its D-12 big-block mainstay with the D-13 and add a smaller-bore D-11 powerplant to complement the large D-16 engine released early in 2005. The first engine from Mack’s new MP (Mack Power) engine family also came out in 2005. The MP7, an 11L diesel could be ordered in Econodyne, Maxidyne or MaxiCruise variants in six horsepower ratings.

DaimlerChrysler AG’s Detroit Diesel Corp., builder of the Series 60 engine and U.S. manufacturer of Series 900 and Series 4000 Mercedes-Benz engines, relocated its headquarters and main production facility to Redford, MI, as it prepared to launch a new engine family that eventually would replace the Series 60, starting in mid-2007.

International Truck and Engine Corp. formed a new partnership with German engine maker MAN Nutzfahrzeuge to develop and produce International-branded engines in the 11L to 13L range. The engines were to be offered exclusively in International Class 8 highway tractors and severe-service trucks, starting in fall 2007.

“Our strategy for enhancing and growing the engine business involves extending our engine product line,” said Jack Allen, president of International’s Engine Group. “This is another significant step in our commitment to deliver great products for customers at a competitive cost structure.”
