Friday 21st October 1955

The 1956 Pontiacs were introduced. For 1956, the engines were bumped to 5.2 litres (316 cubic inches) and the horsepower up to as high as 227. The Chieftain Special received two more models with two- and four-door Catalina hardtops, while the Custom line dropped the two-door sedan and gained a four-door Catalina hardtop sedan. The front bumper became a one-piece bar with round bumper guards and reverse slash body mouldings appeared.
