Probably only for speeds below 40 MPH because aerodynamics, which I think for many last-mile delivery vans would be okay. Could probably even fit more shelving in the back.

congratulations, you have invented the 'sprinter-but-worse'. or as they say in germany, der verschlimmbesserungssprinter.

I think you mean the ULTRA-CUBE

Yes this is completely possible. Think of vehicles like cargo vans and trucks they are usually fairly boxy designs.

The concept you shared is close to the canoo designs and concepts. Chevrolet in North America has a cargo van that is also similar to this concept and it is production now.

At on road speeds the aerodynamics are more about efficiency then top speed so in theory you would be able to drive at highway speeds, just wouldn’t be as efficient as it could be.

As for the interior a lot of “commercial” use vehicles are sold without interiors beyond what is meant for say the driver and one passenger. The back area being for cargo space is usually empty. This way you can outfit the back with what you need depending on your needs. Like shelving or drawers etc. or if you want seating that will be a more expensive trim option.

PFFFTHAHAHA! Look at that little chode of a ramp! It doesn't even reach the ground! HAahaha it just made everything shorter lmfao

The Canoo designs were pretty bad though and ended up costing way more than they should have. The K BOX ULTRA CUBE design would be much cheaper because cube.

It's designed so it can poop out boxes from the back without needing to stop. Maximum efficiency, never even stops rolling.
