Of course, now that F1 cars have an abundance of recovered energy I'd like to see the use of electrically driven pumps. This would allow the pumps to be run at variable speed/flow giving much better efficiency, and the pumps could be remotely located from the engine giving more packaging flexibility. Production cars are already heading in this direction. F1 should do likewise.

+1 new (2014) rules are shite in that regard. Accessories should be driven by nothing but recovered energy. Maybe trubo driven accessories. Rules say they must be engine driven but the turbo is part of the engine innit. To answer the OPs question look for a technical paper on the BMW F1 engines from the 2000s. Some of the engine blocks were absolute works of art: 2.5mm thick castings with all the accessories integral to the block etc.
