Navistar's ‘ground up’ approach to all-new DIESEL ENGINE

The S13 Integrated Powertrain will be Navistar's final clean-sheet design of a diesel ICE powertrain.

Though electrification has taken center stage for the commercial trucking industry, diesel ICE powertrains will continue to serve as the preferred propulsion system of many fleets for decades to come. Navistar has committed to keeping the diesel combustion engine relevant for the near future by revealing the S13 Integrated Powertrain.

Truck & Off-Highway Engineering was on hand for the company's reveal event in Las Vegas, where Navistar proclaimed that the S13 will be its final clean-sheet design of a diesel ICE powertrain. The S13 is intended specifically for the North American commercial-vehicle market. It was developed over the past five years in a global collaboration effort by the Traton Group, which encompasses Scania, MAN, Volkswagen Truck & Bus, Navistar and RIO.
