Back when the CX chassis was being developed it was rumoured there would be a Plus Three
My money is on a CX chassis with a transverse 3 cylinder BMW engine and FWD.
As the "Plus Six Restoration" article in Miscellany makes clear, the rear subframe is a seperate part, so a new subframe with a single rear wheel wouldn't be a big ask, especially as no drive shaft/differential would be needed.
So, let us wait and see...
Also, a PlusThree E with electric drive wouldn't be difficult next step.
