The scorecards rank each supplier on quality, systems cost, technology and the ability to deliver a part, according to David Barnas, a spokesman for Chrysler Group.
Barnas said the automaker believed that showing suppliers where they stand in relation to their competitors would help drive down costs and improve quality. Chrysler also wanted to ensure that suppliers were not charging different business units of DaimlerChrysler different prices for the same parts.
Chrysler will share information with the suppliers but what they do with that data is up to them, Barnas said.
"Information is nothing to be afraid of," said Peter Rosenfeld, Chrysler's vice-president of worldwide production and supplier commodity strategy. "What a supplier chooses to do with the information is their free choice."
Barnas said Chrysler would not use uncompetitive suppliers, adding that the company had shifted $5bn (£3.23bn) in contracts among suppliers over the past three years, mainly because of quality issues.
The online scorecards will be rolled out within the next six months.
