I really do not know what these journalists expect.
Yes the Mk4 Jazz and the HRV have the same ICE engine and yes the ICE engine (any engine) will make a noise, when pushed, but I maintain that this noise is no more than, any similar car and certainly much less than any previous Jazz.
Its just the fact that the vehicle is overall so very quiet and when the engine does start up to drive in the manner described in the video, yes it can be heard, but in my view not abnormally so.
In normal motoring you mostly cannot hear the engine start or stop, particularly if your playing your favourite music as well.
Anyone who complains about the noise as described will need to stick with a pure EV vehicle
