Mack » Mid-Liner MS 1st series
Since the 15.7 million shares of Mack Company become freely bought and sold, the company has established a particularly close relationship with Renault. In 1977 two companies were thinking about joint production and sales of 6-7 class trucks in North and Central America and the Caribbean. As the result, Renault and Mack developed joint plans to produce the Mack Mid-Liner range in 1979. Renault increased its stake in the assets of MACK up to 40%. Later, in 1987, there was a financial restructuring in Renault company and a new subdivision Renault V.I. fully bought all of the Mack assets from Renault. The Mid-Liner MS was a modified truck Renault S/M series. Lighter version MS200P was equipped with a turbocharged diesel engine with an output of 175 hp and 5-speed transmission Spicer; while the heavier chassis MS300P and truck tractors MS300T were equipped with 210 hp (later 215 hp) engines and 5-, 6-speed transmission RVI. Medium versions MS250P and MS250T with the same engine as MS200P model were presented later. There was a conventional model CS also in the Mid-Liner range.
