Over 20 models of hybrid vehicles - including passenger cars and trucks - are eligible for purchase under the federal rebate program cash-for-clunkers which kicked off Monday to boost sales of vehicles in the strained U.S. auto industry.

The cash-for-clunkers program requires interested buyers to trade in an old vehicle they own in exchange for a rebate which can be up to $4,500. The award must be used for the purchase of a brand new car or truck through an auto dealer registered to participate in the government's program.
