Mazda RX-8 9500rpm

Rotary engines lend themselves to high revs, because there are no pistons going up and down in cylinders, instead a triangular rotor that spins around a central shaft. The Mazda RX-8’S 228bhp 1.3-litre engine is a twin-rotor design, meaning it has two chambers that share the same central shaft. This design also gives the RX-8 a distinctive sound when it’s pressed towards its 9500rpm rev limit. And you do sometimes need to do that, because just 159lb ft of torque is available.
