Sure, but so far most European Diesels weren't able to pass emissions in 
California. And wasn't there that company in Germany that made soot 
filters that turned out not to work and they knew it? Read something

No idea. AFAIK they keep them between 50% and 80% charge to make them 
last. So far none of the neighbors here has needed replacement and most 
of them use the Prius for lengthy daily commutes, including a grade you 
have to tackle to get up here.
