The Ford Motor Co. is making a major investment in its electrified vehicle development program. The company is ploughing $4.5 billion into the project with the aim of making 40% of its global vehicles hybrids, plug-in hybrids (PHEVs), and battery-electrics by 2020.

Raj Nair, Executive Vice President of Product Development and CTO at Ford says they will  add 13 new EVs and hybrids over the next four years. This will raise the percentage of electrified vehicles in its line-up from 13% in 2015 to 40% by 2020.

A large part of the expansion will be based around the introduction of a Focus Electric in 2016. Ford says this car will be able to achieve an 80% charge in just 30 minutes, although there are still concerns over its 100 mile range.

The investment comes at a time when sales of electric vehicles are struggling in Ford’s home US market due to low fuel prices. Hybrid Ford sales fell by 25% in 2015. Other electric vehicles also fared badly in the year with Nissan Leaf US sales down 41%, Chevrolet’s Volt plug-in hybrid sales down 23% and Toyota Prius sales down 12%.However, this is seen as a temporary decline with electrified vehicles still seen as the future by major car makers.
