International Truck and Engine Corporation gave its customers a preview of what to expect from changes required in its trucks to meet the more stringent EPA emissions guidelines coming into effect in 2007: rising prices and a greater degradation of fuel economy than expected.
International noted that it is working to minimize the impact of both on its customers, and that it is also committed to achieving comparable performance to what customers see today.
Prices for International mid-range diesel powered trucks and IC buses will increase an estimated $5,000 to $6,000 per vehicle. International Class 8 truck/tractors with supplier engines, should see an increase in the range of $7,000 to $10,000. Additional charges will apply with certain engines where higher horsepower requires dual aftertreatment.
The company announced that based on current tests of International engines, it was estimating fuel economy would degrade beyond the 1 percent already expected with the use of ultra low-sulfur fuel. International said that it is working on solutions to close that gap.
For its family of mid-range engines, International will be optimizing exhaust gas recirculation (EGR), and using proven air management and fuel injection systems in addition to a diesel particulate filter based upon six years of Green Diesel Technology vehicle development.
International also noted it is closely collaborating with its engine suppliers, Caterpillar and Cummins, both of which will be using cooled EGR strategies, for the 2007 solutions in its Class 8 trucks.
