Hello Natasha,

From, what I heard 3 cylinder engine will vibrate more on the
steering wheel when travelling at high speed as compare to the 4
cylinder
Yes, it is true. My Daihatsu Charade which has 3-cylinders
vibrates when travelling at 110 km/h - its max. speed.
The concept is simple, the more cylinders an engine has, the more
powerful it would be.
But of course if we are looking for budget cars (1000cc or less),
we can't expect to be getting really powerful engines, can we?
