A U.S. bankruptcy judge has approved bidding procedures for the rapid sale of most of bankrupt vehicle maker Chrysler's assets.

Chrysler had asked for permission for a quick sale of most of its assets to a new company held by Italy's Fiat SpA, a United Auto Workers union-aligned healthcare trust and the U.S. and Canadian governments.
