The F-150 truck, Ford Motor Co.'s top revenue generator, is getting a makeover that focuses more on the inside than the outside, 

adding amenities like hands-free driving technology and reclining sleeper seats.

It turns out that truck purchasers, who bought almost 900,000 F-Series automobiles last year, were in high demand for sleep, 

as seen by the $42 billion in income they brought in for the carmaker.

Ford spent hundreds of hours researching its customers' cultural needs before realising that 

what they truly want is seats more equivalent to a first-class aircraft cabin than a basic shuttle bus.

"We're finding that a lot of consumers use their car as their sanctuary, 

whether it's simply for a fast power nap when they're on the job site or when they're going camping with their family, "

Ford's head of product development, Hau Thai-Tang, stated in an interview. 

"When they return from work, they won't immediately enter the house. In fact, they will spend "me time" in the truck."

Ford realised the F-150 couldn't rest on its 38-year reign as the best-selling car in the United States, so it decided to improve the cabin.

To compete with competitors General Motors Co. and Fiat Chrysler Automobiles NV, the truck needed an upgrade.
