Freightliner Trucks will begin rolling out its Business Class M2 line of medium-duty and vocational trucks to the Mexico market this summer. Production begins in June at the company's Santiago Tianguistenco, Mexico, manufacturing plant. With the introduction of the new truck line, Freightliner said the plant will increase its production rates. The Class 5-8 medium-duty trucks were unveiled to the U.S. and Canada markets last year.
