The remarkable, liquid-cooled, three-cylinder engine is light and powerful, offering high torque at low rpm. The acoustic harmony which results from a combination of the induction sound and exhaust note gives the CP3 its recognisable roar, which heightens the feeling of acceleration. The fuel injectors give increased efficiency, while optimised gear ratios and a refined A&S (assist and slipper) clutch match the high output of the engine.
