Chrysler has announced that its senior vice president of design, Trevor M. Creed, is set to retire at the end of the month after spending 23 years with the company. Creed is credited with being involved with the design of some of the carmaker’s most memorable concept and production cars since the late 1980s including the PT Cruiser, Dodge Viper (pictured) and Ram pickup.

Replacing him as the new vice present of design will be Chrysler’s rising star, Ralph Gilles, who was responsible for the 300 sedan and more recently the Challenger muscle car.

Creed joined the Company in 1985 as the director of interior design after having previously worked at Ford. In 1995 he was presented with the Automotive Interiors Magazine Lifetime Achievement Award, and in 2005 he was an Automotive Industries Magazine Executive of the Year recipient.

In another management reshuffle at the Auburn Hills company, Andreas A. Schell has been appointed as the new vice president of the carmaker’s electrical engineering division. Schell first joined Daimler in 1996 as a research engineer and most recently served as Chrysler’s director for recovery and transformation.
