Comparing it to the 130EX concept, you can see a lot of similarities. The overall shape, the wheels separate from the body, even the color.
Now it’s very possible that it’s just a coincidence - the Tasco prototype is obviously very obscure - but since it is housed in a major art museum, I don’t think it’s a stretch to say Rolls-Royce designers looked to the past to design the future. And yes I realize how incredibly corny that sounded.
