I wonder why they have more precious metals in them?

I would guess that is related to the gas engine "On/Off" nature of hybrids...the catalytic converter needs more catalyst (rare earths, platinum/palladium) to heat up faster after restarts. Conventional cars have the gas engine on all the time and once the converter reaches operating temp it stays there. (Just my guess...haven't looked it up).
