Ford Motor Co. plans to introduce a new hybrid gasoline-electric car in late 2018 to compete against the best-selling Toyota Prius, two sources with knowledge of the company's plans said on Wednesday.

The compact car will be Ford's first "dedicated" hybrid — that is a vehicle designed to be marketed exclusively as a hybrid, rather than a variation of an existing gasoline model, such as the automaker's Fusion hybrid, the sources said. The as-yet-unnamed vehicle will be built just outside Detroit.

The sources said Ford eventually could offer several different body styles of the new hybrid, as Toyota does with the Prius. There would be different versions of the car's gasoline-electric drivetrain, including a more expensive plug-in model that can be recharged from an electrical outlet.
