just FYI fuel consumption above 15L/100km is shithouse.
Funny how everyone I know with rotary powered cars never seems to have them on the road for more than a month or two at a time, and are getting fuel consumption skywards of 15L/100km. (AFAIK the R32 GT-R is quoted at around 16L/100, and GTS-T at 10L) Thats why I mentioned reliability, and fuel consumption, from my own experiences. The OP asked why they suck (and if they were any good they would be in mainstream use), and apart form epic thread diversions and invasions from RX-7 owners, is being told opinions why.
