Toyota Motor Corp. is objecting to a fuel-economy target of 54.5 miles per gallon (23.17 km per liter) by 2025, which competitors support, as the Obama administration seeks to reach a consensus among carmakers selling in the U.S., according to three sources.

Toyota and some European carmakers say Ford Motor Co., General Motors Co. and Chrysler Group LLC are getting a break because fuel-economy standards for light trucks will rise more slowly than for cars, said the sources.

Obama is scheduled to make an announcement about the fuel standards Friday.
