The guys over at Forbes must have missed the well-selling RX-8 (?)


There's a good reason that rotary engines never really caught on. Rotaries--which run in circles, unlike pistons, which run up and down--are like diesels; they had major problems early in life, creating a buying populace that to this date does not fully trust them. Mazda's RX-2, one of the first rotary-engine cars, had problems with catching on fire. It also raised the classic problems of rotary engines: bad fuel economy and emissions. Rotary seals would wear out early in an RX-2's life, leaking fuel and emissions along the way.
