Overtaking the Leaf in regards to range, not sales.
But as production in concerned, there are changes coming.
The lower volume Fiesta is moving from the 'duty free' Mexican plant to Thailand and importing it back to the US/North America/Canada/South East Asia. And that 'import tax free' Cuautitlan plant is being retooled to produce more higher volume C-Platform vehicles, like the next gen MY2017/18 Focus and C-MAX.
This capacity expansion for C-Segment vehicles will allow Ford to ramp up production necessary for the demand for the more aerodynamic, lighter weight, aluminum content Focus and C-MAX. Along with the launch of a new more efficient hybrid platform and drivetrain.
This first gen/current 'retrofit' version of the Focus Electric, C-MAX Hybrid and Energi, and upcoming Focus Energi, with battery packs taking up cargo space, and excessive vehicle weight were just a start. Generation 1 of Ford electrified vehicles.
With Fords massive quantities of scale, and the massive use of aluminum in the #1 selling vehicle in the US(along with Lincoln new models), enables Ford to produce an all aluminum, super lightweight hybrid, and use aluminum panels on other models at minimal increased cost.
Speculation is that Ford will either use the next gen Focus hatch as the primary 50+mpg hybrid Prius lift back killer, or it will be the next gen more aerodynamic, lighter weight aluminum based C-MAX Hybrid that will take the throne. Either way, Ford is going after the heart of the Prius line up to take it down.
We may even see an aluminum hood for the refreshed MY2015 Focus and MY2016 C-MAX to drop weight and improve mpg, since the stamping plant for those parts, has already been upgraded to handle aluminum for body parts of other Ford vehicles. Current F-150 and Navigator already use an aluminum hood.
Oh yes.....changes are coming....
