GH Sigma

The GH model was released in 1980. It sold so successfull that Mitsubishi Motors actually bought out Chrysler Australia. The big change externally was the introduction of square quartz halogen headlights and deeper bumpers front and back. Three luxury levels were again available, the SIGMA, GL and SE. Engine choices were still the 1.6 litre Saturn engine for the SIGMA and 2.0 litre or 2.6 litre Astron for the GL and SE. The 2.6 litre was now built with what Mitsubishi called the "silent shaft". Their marketing claimed this made for a smoother running engine which offered the power of a six cylinder and the economy of a four cylinder.
