I never turn my engine off at petrol stations!

I like the part where the OP says there is also a 2.6L version after someone corrected him saying it's a 1.3!
It's hilarious seeing someone know so little after thinking they know so much. We've all been there at one stage though.
why does it say 2616cc on the log book It's hilarious seeing someone know so little after thinking they know so much. We've all been there at one stage though.
Because the rotors form 3 combustion chambers and in use one will be combusting and the other exhausting, whereas a conventional piston only has one chamber. So the 2600cc is the total volume of 2/3rds of the available chamber space. Mazda disagree and say that each rotor = 1 piston therefore they measure 1/3rd of the available chamber space.

It's definitely a 1.3.
"The actual "full" displacement of a 13B is 3.9L, but that is from 1 full rotation of the 2 rotors. **But** 1 full rotation of the rotors turns the crankshaft (or properly called an "eccentric" shaft on a rotary) *3* times.Since a piston engine rates it's displacement based on 1 rotation of the crank, Mazda follows suit and rates the rotary by 1 crank revolution... so 1/3 of 3.9L is 1.3L.
From a power output perspective it's really a 2.6L as you get twice as many "power-strokes" from a rotary then from a piston engine. This is why rotary engines are so powerful compared to its size."
