Ford on Thursday released a teaser shot of its redesigned 2021 F-150 and confirmed the reveal of the pickup truck on June 25.

Prototypes have been spotted testing in public for over a year and already revealed many of the design details.

The new F-150 is more of a heavy update of the current generation than a true redesign, though there will be some significant changes made beyond just the styling.

For example, Reuters reported Thursday that there will be a sleeper-seat option where the seat will be able to recline enough to enable its occupant to lay flat.

Large digital screens for the instrument cluster and infotainment are also expected, judging from spy shots of prototypes. The new tech will also include more connectivity options and over-the-air updates.

In the powertrain department, we know Ford is cooking up plug-in hybrid and battery-electric options, though timing on these isn't clear.

For the pure gasoline powertrains, expect V-6 and V-8 options to remain. It's rumored that Ford is developing a new 4.8-liter V-8 to replace the current 5.0-liter mill, though. There will also be some diesels for serious towing fans while a new F-150 Raptor should stick to twin-turbo V-6 power. A 10-speed automatic should be standard on most, though most likely not on the EV model.

Stay tuned for the reveal in less than a week.
