Wow, so they are doing a wet belt. That's rare. Almost every manufacturer has gone away from belts and back to chains for durability reasons. Countless engines were turned to scrap when the belts aged and broke. Ford's 1.6 CVH was famous for that.
The ECU controlled oil pump is surprising. I have seen the variable displacment pumps before, thinking of some automatic transmissions. But that is a good way to cut pumping losses.
