International delivers on-highway trucks with A26 engine

New engine to deliver fuel efficiency and uptime in the Class 8 market in the US


International Truck has started delivery of its LT and RH series vehicles with the company's new 12.4-litre A26 engine in the United States.

International’s internal testing showed that the products are delivering up to nine per cent in fuel economy improvement over the comparable models built only a year ago.

"Delivering our 12.4-litre engine is a significant milestone for Navistar," Navistar COO Persio Lisboa says.

"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."

International says the engine components have been engineered to deliver customer uptime in the Class 8 market, fuel efficiency, reduced weight and quiet operation.

Built from the MAN D26 engine crankcase, the A26 produces up to 349 kW and 242 kg-m of torque from a design that's 272-317 kg lighter than a traditional 15L big bore engine.

It was developed by team of powertrain engineers under a new initiative called Project Alpha.
