The first such effort, and the first of its kind for Hyundai, is "Mash and Seek," an Internet promotion in which 16 randomly chosen people who have never met each other and know nothing about each other are split into teams of four that have to find one another to win four Elantra sedans.
The effort begins this week with a Web site as well as with online ads urging consumers to visit it to enter for the April 30 random drawing of the 16 names. -- Karl Greenberg
