Automakers make concept cars for one of two reasons.

A: They have a good idea of what their next car will look like and want to share, but aren’t ready to reveal a final version yet.

B: They have a vague idea of what the future looks like and want to share, but aren’t ready to put real money or effort behind whatever wild plan they think might get them through it.

The core of this Fiebertraum is the unadorned chassis, including the wheels, powertrain, and all the (unspecified) bits that make it drive itself.

The idea, as pitched by Mercedes, is that the vehicle could take on whatever form is most needed at any given moment—hustle commuters to work in the morning, swap bodies and spend a few hours delivering packages, go back to passenger service for the evening rush hour, do the overnight shift moving bulk shipments around—only stopping to charge its batteries.

It’s unclear why the cargo body looks like a loaf of bread spray painted silver, or why the designers modeled the passenger setup on a hard boiled egg that someone dropped onto a deli slicer.
