WARRENVILLE, Ill. — The International ProStar has officially been recognized by the Environmental Protection Agency as a SmartWay-eligible tractor because of its superior environmental and fuel consumption performance compared to traditional tractors and trailers.

We have been working continuously to develop best-in-class fuel economy and lowest cost of ownership in our Class 8 trucks, and our breakthrough technologies are making a real difference in helping reduce emissions and protecting our environment, said Robert A. Weber, Internationals chief engineer for the heavy truck group. It is rewarding to be recognized for our efforts in such a formal way. The associated logo that we can now adhere on our products is a valuable tool for helping our customers to make environmentally responsible decisions.

Eligibility for the SmartWay Transport Partnership is based on a comprehensive set of fuel-saving, low-emission equipment specifications for new class 8 long-haul tractors and trailers. The specs are aimed at achieving fuel savings of between 10 and 20%, lowering greenhouse gas emissions and significantly reducing NOx particulate matter and other air pollutants.

Specifications for the SmartWay eligible tractors include: 2007 model year engines, integrated cab high roof air fairings, side fairing gap reducers, fuel tank side fairings, aerodynamic bumpers and mirrors, options to eliminate periods of extended engine idling and fuel saving low rolling resistance tires.

During the development of the International ProStar, International worked with Caterpillar, Cummins and International Engine to design a tractor that could accommodate the 2007 emissions compliant engines offered by each of these manufacturers including the CAT C13 with its clean-diesel ACERT Technology, Cummins ISX engines from 385-600HP and the MaxxForce 11 and 13.

The EPA says that SmartWay trucks will, on average, be 22% more fuel efficient than trucks that arent comparably equipped, and will be at least 10% more fuel efficient than the best combination-unit trucks on the road today. The SmartWay Truck will be an evolutionary requirement so as technology improves, more stringent requirements will be developed to qualify as a SmartWay Truck. The agency intends to revise the criteria in 2010 and will seek an additional 10 percent fuel-economy gain as well as meeting the more stringent 2010 emission standards.
