Ford Motor Co. (F) and Nissan Motor Co. (NSANY) received a combined total of $7.5 billion in federal loans to develop more fuel-efficient cars and trucks.

Ford was awarded $5.9 billion to use in plants across five states while Nissan will get $1.6 billion to invest in its Tennessee plant.

Ford Chief Executive Officer Alan Mulally said he anticipates repaying the loans in 2012.

U.S. Energy Secretary Steven Chu, in remarks Tuesday following a speech in Dearborn, said the Department of Energy is in discussions with Chrysler Group LLC about possible loans and is waiting on General Motors Corp.'s (GMGMQ) bankruptcy reorganization.

"These loans are designed to ensure America's competitiveness," Chu said.

Chu also confirmed that Tesla Motors will receive $465 million to further develop one of its fuel-efficient vehicles.

And he said he hopes to make awards to parts suppliers and battery makers within the coming months.

Congress approved the creation of a $25 billion fund in 2008 to help car companies and suppliers develop green vehicles and components.

Auto manufacturers must meet new fuel-efficiency standards of at least 35 miles per gallon by 2020, a 40% increase over current standards.
