DTNA brings its trucks to Washington DC

This special "Smartplex" training truck -- crafted onto a Freightliner Business Class M2 106 medium-duty chassis -- will be setting out soon on a 10-city tour to highlight this technology's seamless ability to integrate trucks with a variety of service bodies.

This 2013 model Freightliner Coronado SD (for 'severe duty') sports a 560-hp DD15 engine cranking out 1,350 ft.-lbs. of torque; a spec earmarked for a variety of heavy haul applications.

DTNA put a variety of its alternatively fueled models on display as well.

This CNG-powered dump truck is equipped with natural gas storage cannisters placed in a special safety "cage" attached to the back of the cab.

This Cascadia CNG-powered daycab configured test tractor already has 70,000 miles on the odometer and recently completed a coast-to-coast run from Long Beach CA to Washington DC refueling only at publicly-available CNG filling stations.

First unveiled at the 2012 Mid America Trucking Show, Freightliner's "Revolution" concept tractor provides a glimpse of the possible commercial vehicle configurations of the future.

This Freightliner 114 SD sports an 18-ft. dump body with 20 cubic yards of capacity and is powered by a DD13 engine.

Here's a truck with big power: a Freightliner Coronado 132 on-highway tractor equipped with a 560-hp DD16 engine generating 1,850 ft.-lbs. of torque -- which can be boosted to 620-hp and 2.050 ft.-lbs. of torque is desired. Thing is, it's still got more than a few aerodynamic "touches" to help operators achieve 6 mpg or better.

This Cascadia 113 model tractor is designed for regional haul operations and thus can only be spec'd with a DD13 engine providing 470-hp and 1,650 ft.-lbs. or torque. Though it's got a 60-inch sleeper, a big 72-inch berth can be selected, too, if desired.
