The first self-driving Ford could be a delivery van

The first self-driving Ford could come in the form of a delivery van.

Ford has said that it plans to roll out a fleet of fully self-driving vehicles for a ride-hailing or car-sharing service in 2021. But the company wrote in a $4 Tuesday that the vehicle could also be part of a package delivery fleet.

Ford showcased its vision for a self-driving delivery van at the Mobile World Congress in Barcelona on Monday.

Details about the delivery van are scarce, especially since Ford has only released a single rendering of the boxy delivery van. But Ford said its "Autolivery" concept is electric and capable of Level 4 autonomy, meaning it can drive itself in certain geographic locations.

Ford isn't the first automaker to explore delivery van concepts.

Mercedes unveiled an $4 at the Consumer Electronics Show in January. The van came with a drone that could automatically pull packages from the van's shelves and drop them at the door.
