Test Program: The SAE J1321 procedure was conducted utilizing fully serviced trucks. One control truck and one test truck operate simultaneously. A single complete SAE J1321 Type II fuel economy test consists of a baseline segment and a test segment. A valid segment consists of three test laps having a spread in test/control fuel consumption ratios not greater than two percent of the highest test/control fuel consumption ratio (T/C ratio) The test route or lap was 40 miles in accordance to SAE J1321 and was representative of long-haul operations.
Vehicle: The control and test vehicles were Class-8 diesel trucks. The Control Vehicle was an International 9400 with a Cummins ISX engine, while the Test Vehicle was an International Pro Star with a Cummins ISX engine.
