I don't know where you've been, but lots of conventional IC engined cars

No they dont.
BMW call it "Efficient Dynamics". I suspect it makes F-all difference
though - just takes a little load off the engine while under load,
rather than storing it to accelerate with.
yep. the dynamo and and water pump used to take about 30% of the car
engine's power before the days of alternators electric fans and so on.
Now its the power steering pump and the air con instead :-)
