The Pontiac Chieftain is an automobile which was produced by Pontiac from 1949 to 1958. The 1949 Chieftain and Streamliner models were the first all new car designs to come from Pontiac in the post World War II years. Previous cars had been 1942 models with minor revisions. First generation (1949–1954) 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: a 239.2 cu in L-head 6-cylinder engine making at 3400 rpm a 239.2 cu in L-head 6-cylinder engine making at 3400 rpm a 248.9 cu in L-head 8-cylinder making at 3800 rpm a 248.9 cu in L-head 8-cylinder making 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. For the 1952 model year, Pontiac discontinued the Streamliner leaving the Chieftain as their only offering. The Chieftain continued with the 120 inch wheelbase. Engine offerings were basically the same except for the 8-cylinder which got a .2 cubic inch enlargement. Horsepower did increase by 10 on the six-cylinder and by 15 on the eight-cylinder. Also, a red light to remind the driver that the parking brake was on was new. In the May 1952 issue of Popular Mechanics, the Chieftain was rated 14.9 seconds for a 0-60 mph time. Front head room was 36 inches, while rear head room was 35.75 inches. In 1953, Pontiac came with a new body style, offering a wheelbase,
