International Truck fuel efficiency package for Class 8 ProStar announced

(Before It's News)

International Truck today announced a new fuel efficiency package for the International ProStar—the International ProStar ES. The ES, short for efficiency specification, offers improved aerodynamics, a drivetrain with advanced downspeeding and what the company says is the most efficient rear axles in the industry.

The ProStar ES was developed to have the lowest wind averaged drag coefficient in the industry. 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 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.

Navistar’s experienced Performance Engineering Team, who developed the ProStar ES, can further optimize customer-specific specifications based on application and duty cycle.

Navistar will begin taking orders for the ProStar ES later this month.
