Newell prototype motorcoach meets 2007 EPA standards

Miami, Okla.-based Newell Coach Corp. has completed over 4,000 miles of testing on a prototype motorcoach that is equipped to meet 2007 EPA emissions standards for heavy-duty diesel engines. The 625 bhp, 2,050 lb./ft. torque Caterpillar C15 engine uses Caterpillar's ACERT emissions technology to meet the new emission standards. The required exhaust particulate filter is located under and alongside the engine instead of within the interior of the coach body and through the roof, allowing the filter to be added without losing any interior space. To confirm performance under a variety of conditions, Newell staff first drove the test coach in the area surrounding Newell's plant in Miami, Okla. Then in early May, the coach was dispatched on a long-distance trip to the West Coast, including many miles of driving in California's Death Valley during 100-degree temperatures.
