Ford has announced the 2015 F-150 will feature a seamless sliding rear window.

Designed to improve "looks and functionality while reducing components and manufacturing complexity," the seamless sliding rear window consists of two pieces of glass instead of the usual three pieces which are separated by vertical seams. When the driver presses a button, the inner window slides to the passenger side and creates an opening.

The company says the design reduces weight - because it uses fewer components - and helps to improve the rear defrost function.

This doesn't sound terribly exciting but Ford body mechanisms manager, Noah Mass, says it's "another great example of the intricate detail that goes into producing the next-generation F-150, setting it apart from any pickup on the market today.”
