LISLE, Ill. (May 19, 2014) – Navistar, Inc. and Swift Transportation today announced a joint pilot program designed to maximize fuel economy. Navistar developed a specification for the International^® ProStar^® tractor that the company expects to deliver industry leading fuel economy results. Swift will pilot test the specification, which pairs the ProStar with the Cummins ISX15 and the Eaton Cummins Smart Advantage automated manual transmission.

“We feel the marriage of automated transmissions with complimentary engine parameters will generate optimal fuel economy performance while also helping retain drivers,” said Bert Kinsel, vice president of Heavy Equipment, Swift. “This, combined with truck aerodynamics should prove to be a winning combination.”

At its heart, the ProStar is a driver’s truck, which is one of many reasons it was chosen as the American Truck Dealers (ATD) Heavy-Duty Commercial Truck of the Year.  The vehicle features the same benefits that have always made it a driver favorite including a one-piece, aerodynamic wraparound windshield providing superior field of vision free of blind spots, a sloped hood and a lower placed instrument panel to ensure drivers have an unparalleled view of the road. The ProStar also features four-point, air-over-strut cab suspension, a wide-track front axle and steering designed to provide on center stiffness to provide superior ride and handling.

“Swift is North America’s largest full truckload carrier and we are looking forward to delivering their International ProStar units with the ISX15 and Eaton Cummins Smart Advantage automated manual transmission,” said Bill Kozek, president, North American Truck and Parts, Navistar.  “Our testing shows this truck configuration provides outstanding fuel economy performance and we are confident Swift Transportation will experience the same benefits we have observed.
