First Generation (1949-1954)

The first generation Chieftain replaced the Torpedo

 as Pontiac's top automobile and was similar (if not exact) in dimensions, engines, trim levels and options to the lower level Streamliner. However, the Chieftain was based on the sportier GM A-Body shell instead of the Streamliner's more staid B-Body shell. They had standard automatic interior lighting.

The Chieftain was initially introduced with four models: Sedan, Sedan Coupe

 was added in 1951.

First generation Chieftains came with a choice of four engines:
  • a 239.2 in³ L-head 6-cylinder

     making 103 hp at 3800 rpm
  • a 268.2 in³ L-head 8-cylinder making 106 hp at 3800 rpm


The horsepower differences between each of the 6- and 8-cylinder engines were due to changes in compression ratios.

Some of the more interesting optional items available for the first generation Chieftain included a radio with seven vacuum tubes, tissue dispenser, under seat heaters, and a Remington Auto-Home shaver. In 1951, the horsepower on the 8-cylinder rose to 116. The Chieftain came with a gas gauge, ammeter, oil pressure gauge, and temp. gauge(which had marks for 160, 180, and 220 degrees Fahrenheit).

For the 1952 model year, Pontiac discontinued the Streamliner leaving the Chieftain as their only offering. The Chieftain moved to the new 122 wheelbase. Engine offerings were basically the same except for the 8-cylinder

 and by 15 on the 8-cylinder.

The 1953 Chieftains were largely unchanged from 1952. The six-cylinder was standard.

 joined the Pontiac line in 1954, bumping the Chieftain down to entry level status. Both cars were built on the A-body shell but the new Star Chief had an 11 inches (279.4 mm) extension added to its frame. Also in 1954, 8-cylinder engines increased by about nine horsepower due to carburetor changes. The 6-cylinder engines remained unchanged.

Also in 1954, power brakes and air-conditioning were offered as extra cost options for the first time. Also a power front seat was added.

Second Generation (1955–1957)

The 1955 model Chieftains featured completely new chassis, body and engine. The engine was the biggest news as this was Pontiac's first V8. The 287.2 in³ engine made 173 or 180 hp at 4400 rpm depending on which version was ordered (again, the difference was due to changes in compression ratios). A 6-cylinder engine was no longer offered. The original five-chrome strips running down the hood and trunk where dropped, with a twin-stripe design used.

The biggest change for 1956 was again in the engine. The new for 1955 V8 was drastically enlarged to 316.6 in³. Horsepower made a considerable increase, jumping to 192 and 205 respectively. Otherwise, the 1956 model Chieftains received only minor updates. A padded safety dashboard was added as an option.

New "Star Flight" styling graced the 1957 Chieftains. This new theme included missile shaped side trim, extended rear fenders with V-shaped tips, lower hoods and massive bumpers. A new Super Chief sub-series debuted within the Chieftain line. These were the meant to be the top of the line Chieftain models. Sales were 58.02% of all Pontiac's in 1957. The first "Tri-Power" Pontiac engines were offered.

Once again the Pontiac V8 was enlarged. The 1957 model year say the engine increase to 347 in³ with horsepower increasing to 290 for the Chieftain models.

Third Generation (1958)

Chieftains went through another major styling change in 1958. All models were give honeycomb grilles, quad head and tail lamps, concave rear fenders, and longer, lower lines. The Super Chief sub-series was promoted to full model status leaving just the standard array of Chieftains as the entry level Pontiac. The "Sportable" transistor radio became an option, along with air-suspension.
As in years past, the V8 engine was enlarged. For 1958 it grew to 370 in³ and made 240 and 270 hp depending on version.

The 1958 models were the last Chieftains to be produced. It was replaced with the all-new Catalina
