'Creating New Possibilities'
Host company Hyundai and Tier 1 Strategic Partner, Delphi,
established "Creating New Possibilities" as the theme for
this year's premier engineering event taking place April 8-10
in Detroit's Cobo Center. This special Congress preview section
uncovers some of those possibilities, featuring insights from the
event's executive leadership; details of a Delphi/Hyundai
advanced engine program; highlights from the technical program in
the areas of powertrain, materials, testing and simulation,
electronics, interiors, and body/chassis; and more.
