None of the answers to this question are correct, as this is somewhat of a trick question. The Mazda RX-8 is a rotary engine, and it has no cylinders. The Mazda RX-8 has a single TWO-rotor engine. Cylinders are only for piston engines. The RX-8 is a 1.3 liter rotary, no I4 or V6, just rotary. The Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion.
All parts rotate consistently in one direction, as opposed to the common reciprocating piston engine, which has pistons changing direction. In contrast to the more common reciprocating piston designs, the Wankel engine delivers advantages of simplicity, smoothness, compactness, high revolutions per minute, and a high power-to-weight ratio.
