This chart demonstrates how Chrysler early adopted standardized body designs; even when products used different bodies, some components were standardized.

While there may be other ways to characterize "shared" auto bodies, the chart below is based on a unique body dimension. The cowl assembly is the "heart" of an automobile body. It's design established important visual parameters like the windshield position and shape, body width and belt height. It also has built-in functional components like front body structure, door hinging, air handling, wiper geometry and pedal pivots. For this reason the cowl is usually the common element of a "Body Family", having variations fore and aft and often used on multiple brands, models and body styles for several years running.

In 1951, Chrysler LLC introduced its entry in the post-war horse¬power race, a V-8 engine designed with hemispherical combustion chambers. Quickly dubbed the “HEMI®,” its power and efficiency made it an instant favorite for all sorts of motor sport vehicles. Although reluctantly retired in 1959 due to high manufacturing cost, the HEMI design was still unsurpassed. In 1964, NASCAR competition sparked the HEMI’s return, and it has remained available for motor sport use ever since. Now, 50 years after the original, there’s a new HEMI whose efficiency and power make it ideal for today’s needs. Open PDF
