Navistar traces its roots back to the founding of International Harvester Company in 1902. Over the years, International Harvester became a leading manufacturer of agricultural equipment, trucks, and SUVs. In 1985, the company changed its name to Navistar International Corporation to reflect its focus on the trucking and transportation industry. Navistar primarily focuses on producing commercial trucks and buses. Their product lineup includes medium-duty trucks, heavy-duty trucks, severe-service trucks, and school buses. Navistar also manufactures engines, transmissions, and other components for their vehicles.
Navistar has been actively involved in developing and implementing advanced technologies in its vehicles. They have focused on areas such as fuel efficiency, alternative fuels, electric vehicles, and autonomous driving technologies. Navistar has collaborated with other companies and organizations to advance innovation in the transportation industry.
As of my knowledge cutoff in September 2021, Navistar continues to operate as a major player in the commercial vehicle industry. The company has been focusing on improving profitability, expanding its product portfolio, and exploring new technologies to meet evolving customer demands.
