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 ES is by far the highest quality and most fuel efficient package we’ve ever offered,” said John McKinney, Navistar senior vice president, Sales and Marketing. “Our Performance Engineering Team has studied, tested and validated hundreds of vehicle, powertrain and component combinations to develop an ‘optimized spec package’ that maximizes fuel efficiency and is easy to order.”
“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.”
