The design has an emphasis on efficiency throughout. All ball bearings, a minimization of parts & gear reductions whenever possible, and no tensioners touch the chain (sliding bearing blocks as already said).
Each item is a small percentage, but I imagine they certainly add up. We run a very similar drive, and teams often comment on how quiet it is.
