Default Is HSD a variable ratio transmission?

It is an elecrtic continuously variable transmission, not a mechanical CVT, mechanically it is always in top gear. It uses a single planetary gear set that "splits" the engine power between the mechanical pathway (in top gear), and the electrical pathways, which take advantage of the torque characteristics of the motors to act as a low gear. Blending the pathways results in continuously varying the torque. I voted "yes" by the way.
