The Myvi boasts either one of two
water-cooled,
four-stroke engines derived from the first generation
Daihatsu Sirion: A 1.0 litre EJ-VE engine with three in-line
cylinders, or the Toyota Passo: 1.3 litre K3-VE engine with
four in-line cylinders; both engines employ
Dynamic Variable Valve Timing (DVVT) systems and
conventional
electronic fuel injection (EFI).
In addition to raw performance, features previously uncommon on Perodua cars were inherited from the Sirion to the Myvi. Among them are 4-hole injectors, foamed urethane injected to the A-pillar, centre pillar and B-pillar for noised insulation, immobiliser systems and pedestrian injury reduction body construction. Other notable features include underbody air flow regulating items, resin intake manifolds and cylinder headcovers integrated with air cleaner cases (for 1.0 engines) and flexible flywheels for reduced vibration during running (for manual transmission).
