While there weren't many big new product announcements at this year's Mid-America Trucking Show last week in Louisville, Ky., there was one theme that rang loud and clear through nearly every product introduction and enhancement announced: improved fuel economy, and as part of that, lighter weight.
A number of truck and engine OEs said the focus is shifting from the battle over which technology is better to meet EPA's 2010 NOx and particulate emissions limits, to an emphasis on fuel economy.
"The past decade was clearly about who could meet emissions best, and I think we did that," said Rich Freeland, Cummins vice president and president-engine business. "The winner of the next decade will be about who delivers fuel economy best."
Cummins said real-world data has confirmed that its EPA-2010 spec ISX15 engine delivers 6 percent fuel economy improvement over its 2009 product. Some customers could see even better results thanks to "significant calibration improvements" Cummins has identified that were launched early this year, said Steve Charleton, Cummins vice president and chief technical officer-engine business.
