True, but for some reason I always read they were classed as a 2.6, or maybe that's the RX7 and they double it to take the turbos into account, I forget
*edit* found some stuff on it:
Renasis is 1.3 (2x 653 cc rotors).
"Cant realy be compared to a 1.3 cylinder engine though. It Breaths as a 2.6 petrol. Each rotor has 3 combustion chambers and fires once each rev instead of once /2 rev."
and
"It's a two stroke engine, thus each cylinder does a 'power stoke' (as it were) twice for every single time a cylinder would in a four stroke. Therefore in comparitive terms, the engines capacity could be considered in the real world as a 2.6 4-STROKE!!
This is officially classed as a 1.3 2-STROKE, and thus gets taxed as such."
So guess it's down to the way the engine works rather than physical size, but yeah I got it wrong and they are two 600 and a bit cc rotors
