Hi!
I agree with using a variable transmition to keep the rpm at max torque but
we have to have a variable size engine to, to get max torque we have to
have wot.if we drive at wot the output will be to high for our use.
Variable stroke is a help but it will be a ineffichent combustion camber
with
the short stroke and the compression ratio will not be good still running
wot.
VW made a variable compression ratio combustion camber, dont ask me how
they did it.....variable combustion camber and variable stroke would 
do the trick .....easy uh....Ore several independant engines coupled
together
