This is called a "hydrostatic drive" . A common implementation of it is on
the large snow cats which ski areas use as groomers for their slopes. I
think the big problem with it is that the drive's efficiency is low enough
that any gains in engine efficiency are negated.

DKW once built a little 2 cycle car with a variable speed belt
tranny--which was a bit of a curiousity.
