Well, for starts...
The CR-Z is about 460 pp stock
The Prius is a bit higher but roughly the same
The Nissan R34 is somewhere just above 600 pp I believe, but I only had a quick look at it.
Haven't checked any other car, although my online race experience tells me that the RX7 is way above the Prius.
Hopefully someone else can give some more extensive info.
