i think the tucker was originally designed for one.

there may have been a tatra or such in eastern europe with one, but i am not sure about that.

it was considered in the early design of several cars i remember reading but it escapes me which except for the tucker. i think it laid flat with the crank vertically mounted.

i seem to remember a very early car prototype in which the radial engine rotated on a fixed crank. i have never seen a picture but it makes something to strain the imagination.
