International Truck today announced a new fuel efficiency package for the International ProStar—the International ProStar ES. The ES, short for efficiency specification, offers industry-leading aerodynamics, a drivetrain with advanced downspeeding and the most efficient rear axles in the industry. In addition, it boasts the spec’ing expertise of International’s Performance Engineering Team and Navistar’s proprietary OnCommand Connection remote diagnostics system.

“The ProStar has an established reputation in the industry for being one of the most fuel efficient trucks on the road and the availability of the ProStar ES raises the bar even higher,” said Jodi Presswood, vice president, Heavy-duty Truck Product Line. “We’re not standing still and we’ll continue to enhance this spec with increasingly more efficient components and advanced technologies.”

The ProStar ES was developed to have the lowest wind averaged drag coefficient in the industry. And its supremacy in crosswinds makes it one of the most aerodynamic tractors, in real-world conditions, on the road today.

The ProStar ES offers the Eaton Cummins SmartAdvantage™ powertrain which pairs the Cummins ISX15 with the Eaton Fuller Advantage™ automated transmission, as well as Navistar’s proprietary SCR-based 13-liter engine and the Eaton Fuller Advantage™ automated transmission. Both are matched with the most efficient rear axles in the industry. The unique SmartAdvantage™ powertrain gives the ProStar ES superior downspeeding capability, allowing it to run at 150-300 fewer RPMs at cruising speed vs. previous offerings. This is part of what enables the ProStar ES to achieve an 11 percent improvement in fuel economy vs. the 2010 ProStar/MaxxForce® 13/10-speed manual baseline.

ProStar ES includes a three year subscription to OnCommand Connection, Navistar’s predictive diagnostic system which includes a portal that monitors vehicle performance in real-time to ensure maximum operating efficiency.
