In 1955 a completely revised Chieftain was introduced. The cars were much slimmer and lower; the moulded rear fenders had disappeared as well as tapered alligator shape of the hood. What remained was the shark's mouth and the car grew small tail fins. Also new were the panoramic windscreens. To the known from the previous body forms a 3-door station wagon came. The special versions were called Chieftain 860, the deluxe versions Chieftain 870. The biggest change, however, was he old, side-mounted in-line engines had been dropped and replaced by a new V8 engine with OHV Valve control replaced. The 4,706-cc large engine delivered 173 bhp (127 kW) at 4400 rpm or 180 hp (132 kW) at 4600 rpm  

1956 were the cars rocket-shaped inserts on the front bumpers and there was an additional body shape a 4-door hardtop sedan. the drive V8 was enlarged to 5.2 L t All vehicles got a larger V8 engine, which delivered an output of 192-205 bhp (141-151 kW) at 5,188 cc.

In 1957, the design was slightly revised again: the cars were larger tail fins and a contrasting side strip, which was widened in the tail fins. This design called Pontiac "Star Flight". Also, a larger engine was installed. The V8 now 5.7L made 227-252 bhp (167-185 kW) and had a displacement of 5,686 cc. The Pontiac was assembled in Australia by Holden, badged as the Pontiac Super Chief model.
