Castaing deservedly gets major credit for developing the all-new line of cars and trucks that paced Chrysler's surging success in the 1990s. He worked on minivan designs using the science of maximizing space usage and was praised by Chrysler's President, Bob Lutz, "as the best packager I've ever known." The success of Castaing's system was exemplified not just by the attraction of Daimler-Benz as the suitor for Chrysler, but by more than just a passing interest from General Motors and Toyota. At that time, the automaker's executives such as Robert Lutz, Thomas Stallkamp, and Francois Castaing "made Chrysler the most nimble of Detroit's three carmakers."
