Freightliner Cascadia Evolution: 10 MPG

Daimler Freightliner’s new pride and joy is not an alt fuel nor hybrid vehicle

The Cascadia Evolution for 2014 is a state-of-the-art diesel, powered by a newly designed Detroit Diesel DD15 engine with such “fuel squeezing options” as wide-base tires, enhanced aerodynamics and DT12 automated manual transmission delivering an impressive 10.67 miles per gallon at the Continental Proving Grounds in Uvalde, Texas.

Daimler's gone with a full-court press on the Freightliner Cascadia Evolution diesel: Will its many efficiency enhancements be applied to natural gas trucks?

On Daimler’s just-wrapped, 2,400 mile, cross-country Evolution of Efficiency tour, the truck achieved 9.31 mpg.

“We are building upon our commitment to maximizing our customers’ bottom lines with new product advancements that will deliver unprecedented fuel efficiency,” said Daimler Trucks North America marketing and strategy GM David Hames.

But don’t expect the same benefits just yet for Daimler’s natural gas trucks. Half of the fuel economy improvement comes from aerodynamics, which are less of a factor, notes one observer, in the regional haul applications that represent the main near term natural gas truck markets.

And, natural gas engine designs “don’t get refreshed nearly as often as diesel designs so it may be a while before we see reduced parasitics [and] turbo compounding” applied to natural gas.
