autonomous semi-trucks. The production is said to start in 2024 Although with non-disclosure of the total investment amount from both the parties, Navistar has taken a minority stake in TuSimple. Corporate operations International Trucks (1986–present) In 1986, after the transition from International Harvester to Navistar, the truck product line (essentially all that was left) continued to use the International brand name. The International brand encompasses a variety of medium-duty, over-the-road, and severe-service trucks. Medium Duty International CV Series (also produced as Chevrolet Silverado C6500 HD) International MV Series Heavy Duty International LoneStar International LT Series International RH Series Severe Duty International HX Series International HV Series IC Bus (2002–present) International has a long history in the school bus industry as a chassis provider, dating to when school buses first became motorized. In 1991, Navistar entered the school bus industry as a body manufacturer when it began its acquisition of AmTran, an Arkansas-based company founded as Ward Body Works in 1933. Today, IC Bus produces several models of full-sized school buses along with buses for commercial use. School/activity buses CE-Series conventional (International 3300 chassis) RE-Series rear-engine transit-style (International 3000 chassis) Commercial buses CE-Series conventional (International 3300 chassis) RE-Series rear-engine transit-style (International 3000 chassis) TC-Series chassis (International 3300 chassis) MWM International Motores (2005–present) In 2005, Navistar purchased MWM International Motores, a Brazilian engine manufacturer formerly associated with Deutz AG. Engines (1986–present) In 1986, Navistar was formed from the engine division of the former International Harvester (alongside the truck division). In a continuation from its predecessor, International produced both gasoline and diesel-fueled engines for its medium-duty trucks and some heavy-duty trucks, offering second-party engines as an option. Class 8 trucks offered second-party diesel engines (from Caterpillar, Cummins, and Detroit Diesel). From International Harvester, International inherited production of the SV-series gasoline V8, IDI diesel V8, DV-series diesel V8, and DT466 inline-6. After 1986, the production of gasoline engines ended, shifting to diesel-powered engines entirely. During the 1980s, Navistar began an expansion of its engine families. For 1986, a 7.3L version of the IDI was introduced; the engine supplanted the long-running DV-series V8 by the end of 1988; the same year, it became an option in Ford trucks. For 1987, the DT inline-6 engine family was expanded to a second engine, as the DT360 was introduced (competing directly against the Cummins 6BT). During 1994 production, the IDI V8 was replaced by the direct-injection T444E V8,
