Pontiac Chieftain Convertible
In 1949 the A-body Chieftain replaced the Pontiac Torpedo as Pontiac's smaller and lower priced model. However, the newly redesigned B-bodied Pontiac Streamliner was now very similar (if not exact) in dimensions, engines, trim levels and options. This was the first time since 1934 that all Pontiacs had the same wheelbase. They had standard automatic interior lighting.
The Chieftain was initially introduced with four models: Sedan, Sedan Coupe, Business Coupe and Deluxe Convertible Coupe. In 1950, a Catalina Coupe was added to the range while a station wagon was added in 1952, with the demise of the top of the line Streamliner wagon.
1949 Chieftains came with a choice of four engines:
1. a 239.2 cu in L-head 6-cylinder engine making 90 horsepower (67 kW) at 3400 rpm
2. a 239.2 cu in L-head 6-cylinder engine making 93 horsepower (69 kW) at 3400 rpm
3. a 248.9 cu in L-head 8-cylinder making 103 horsepower (77 kW) at 3800 rpm
4. a 248.9 cu in L-head 8-cylinder making 106 horsepower (79 kW) 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 a temperature gauge which had marks for 160, 180, and 220 degrees Fahrenheit.
