The 1981 first-generation Dodge Ram design was typical of pickup styling in those days -- a squared-off body sporting a bold grille. The Wikipedia entry on "Ram Pickups" notes how the redesign for 1994 came to be.
What Chrysler stylists did was create a more rounded, more graceful shape. One might expect that this "feminized" effect would run counter to expectations of trucks having rough 'n' tough "masculine" personalities. What made the design truck-like was the bold, Dodge "gunsight" grille that served to counteract the curves. The result was a huge sale success, an increase of about six times between 1993 and 1996.
General Motors and Ford eventually redesigned their pickup lines and Ram sales levels retreated. Future Ram styling moved in a more powerful, less graceful direction. That evolution does not detract from the 1994 Dodge Ram's important place in transportation design history.
