The Energy Department said Tuesday it would lend $5.9 billion to Ford Motor Co. and provide about $2.1 billion in loans to Nissan Motor Co. and Tesla Motors Inc., making the three automakers the first beneficiaries of a $25 billion fund to develop fuel-efficient vehicles.

Dozens of auto companies, suppliers and battery makers have sought a total of $38 billion from the loan program, which was created last year to provide low-interest loans to car companies and suppliers retool their facilities to develop green vehicles and components such as advanced batteries.
