Ford Motor will invest an additional $4.5 billion by 2020 in programs to broaden its offerings of hybrids and electric vehicles, Chief Executive Officer Mark Fields said Thursday. Fields said it will launch late next year a new version of its Ford Focus electric car that has a 100-mile range and can recharge in 30 minutes.

Ford also plans to add 13 new plug-in hybrid, hybrid or electric vehicles to its lineup by 2020, moving to more than 40 percent the share of the company's vehicle lines that will be electrified.

Plug-in hybrid systems allow drivers to operate part of the time on batteries recharged from the grid, and part of the time on gasoline.
