But once you clear the conges on, the Pacifi c Northwest off ers stunning vistas and great roads. And while it is true that this area is Kenworth's home turf, it is also true that you'd be hard-pressed to pick be er ter- rain to test a new 11-liter Diesel engine and terrain-following cruise control system. The new MX-11 was, like its big- brother MX-13, designed by Paccar's DAF subsidiary in The Netherlands where it underwent extensive test- ing on the European continent since its debut there in 2013, eventually logging 250 million miles there, with another 2 million logged here in North America. Interestingly, Paccar builds the new engine at its manufacturing facility in Columbus, Miss., with many of those engines fi nding their way back across The Pond to Europe. The MX-11 features several new design points that were not avail- able when the MX-13 engine was on the drawing board. There are new, modularly-designed components, for example, including an interesting new water pump that features cartridge- style sections that can be replaced without removing the entire system. If the impeller or the belt assembly goes bad, a technician can simply remove and replace those modules and go on his way. A glimpse of the future can be seen in the MX-11 as well: The engine has been designed from the ground up to be quickly updated with new software and can be programmed to meet specifi c customer requirements. Actual engine displacement is 10.8 liters, which works out to 355 to 430 horsepower options with torque ratings ranging from 1,250 to 1,550 pound feet.
