Though it was just launched a few months ago in January, Kenworth says the new 11L engine already is going into 5% of the T880 vocational trucks being produced. "It saves 400 lbs. over the MX-13 and it's great as a light-weighting option," noted Kurt Swihart, Kenworth's marketing director, adding that the company is seeing uptake of the engine in bulk hauling, less-than-truckload, regional haul and pickup and delivery applications.

"We very pleased and we see a lot of upside potential for it," Swihart said.

Aaron Marsh

Before computerization had fully taken hold and automotive work took someone who speaks engine, Aaron grew up in Upstate New York taking cars apart and fixing and rewiring them, keeping more than a few great jalopies (classics) on the road that probably didn't deserve to be. He spent a decade inside the Beltway covering Congress and the intricacies of the health care system before a stint in local New England news, picking up awards for both pen and camera.

He wrote about you-name-it, from transportation and law and the courts to events of all kinds and telecommunications, and landed in trucking when he joined FleetOwner in July 2015. Long an editorial leader, he was a keeper of knowledge at FleetOwner ready to dive in on the technical and the topical inside and all-around trucking—and still turned a wrench or two. Or three. 

Aaron previously wrote for FleetOwner.
