Built for efficiency and reliability.
The Columbia® was designed for maximum reliability, efficiency and productivity. That’s why it’s the best-selling truck on the road today. The Columbia helps businesses run smart by lowering their overall cost per mile, maximizing fuel economy and minimizing maintenance costs. Simply put, the Columbia gives back more thanyou put into it.

Designed for productivity.
No matter which Columbia configuration you choose, there’s a purpose behind every design feature. The aerodynamic body – tested in our state-of-the-art wind tunnel – reduces wind resistance and improves fueleconomy. The cab is manufactured from lightweight aluminum, allowing more payload. The expansive windshield and low, sloped hood provide maximum visibility while the thermal insulated cab makes the driver more productive by blocking excessive road noise. Even the bumper boosts efficiency with its aerodynamic shape and three-piece design that minimizes repair costs by allowing individual sectionreplacement.

EPa ‘07 Compliant Power System
Heavy-Duty after-Treatment Device mounting Configuration For on-Highway use The ePa ‘07 compliant powersystem features an exhaust after-treatment device that breaks down soot and captures ash in a diesel particulate filter. This device is mounted under the chassis and replaces the muffler assembly. servicing simply entails cleaning or exchanging the filter and would be performed by a technician at a service shop in combination with other scheduled maintenance. service is required no more often thanevery 150,000 miles or 6,000 hours of service. Engine – all 2007 engines must comply with stringent emissions regulations to lower the levels of nitrogen oxides and particulate matter. The new engines run on ultra low sulfur diesel fuel and use low ash engine oil. after-Treatment Device – This double walled device captures soot and ash. soot is broken down through regeneration. ash remains trapped ina section of the aTd known as the diesel particulate filter. Regeneration – soot is broken down through a process known as “regeneration”. This process takes place inside the aTd, two different ways; Passively and actively. Passive regeneration is an ongoing process that happens as the truck is operated and the internal temperatures of the aTd are high enough to break the soot down. an activeregeneration requires even higher internal temperatures in the aTd, breaking down soot through oxidation. The additional heat required is achieved by either passing diesel fuel through the diesel oxidation catalyst on a detroit diesel or Mercedes-benz engine or with the caterpillar Regeneration system on a caterpillar engine. Exhaust System – all ePa ’07 compliant configurations feature stainlesssteel exhaust piping. Cooling System and Radiator – engine cooling is more efficient thanks to a high capacity cooling system and an engine-mounted radiator.
