LISLE, Ill., June 30, 2017 /PRNewswire/ -- International Truck announced today that it has started customer shipments of its first International^® LT Series and International^® RH Series vehicles with the company's 12.4-liter engine. The company's internal testing shows these products are delivering up to nine percent in fuel economy improvement over the comparable models built only a year ago.

"Delivering our 12.4-liter engine is a significant milestone for Navistar," said Persio Lisboa, Navistar executive vice president and chief operations officer. "We continue to receive great customer feedback on the products we're delivering today. Customers will continue to experience outstanding levels of quality, reliability and uptime with our new family of Class 8 on-highway trucks, now complete with the A26 engine."

Driven by a commitment to deliver customer uptime in the Class 8 market, the A26 was developed through an initiative called Project Alpha, which brought together a new team of the industry's foremost powertrain engineers. Built from the proven MAN D26 engine crankcase, the A26 produces up to 475 horsepower and 1,750 lb.-ft. of torque from a design that's 600-700 lbs. lighter than a traditional 15L big bore engine. Its components have been carefully engineered to deliver uncompromising uptime as well as class-leading fuel efficiency, reduced weight and quiet operation.
