Brilliant engine IMHO. I'd be tempted by the RX8 too if I had anywhere near
enough money for one :)

However, the rotary engine cannot be compared on a one-to-one basis with a
reciprocating piston engine. The norm for finding equivalent capacity is to
roughly double the rotary chamber's basic capacity. Here's but one reference for
that:

It has been done that way for as long as I've been collating specifications - at
least 15 years.
