Chrysler 300 “Letter Cars”
Even before muscle cars were a thing, Chrysler produced a series of high-performance luxury coupes and convertibles that delivered unbelievable performance and excellent style. The model was called 300, followed by letters of the alphabet, with the C300 being the first model in 1955. Known as the Letter Series, those upscale cruisers were some of the fastest and most powerful models produced from 1955 to 1965 (via Car Throttle).
The first models had early Hemi engines, which could produce 300 horses (hence the name). Early Chrysler “Letter Series” models were the first American cars with 300 HP ratings. The “Letter Series” models were always costly and produced in very limited numbers. Throughout the years, Chrysler’s “Letter cars” combined luxury and limited availability with fantastic performance and style, making them one of the best examples of the personal luxury class.
