I often read posters commenting on how noisy the engine is, at motorway speeds. Today I was sitting at an indicated 75 mph (70 on GPS) and the predominant background noise was road noise. I could here the engine, but it was neither prominent or intrusive. In fact, when I switched the radio on the only noise evident was road noise. particularly from other vehicles. Maybe I am just easily satisfied, but the Jazz is no noisier, enginewise, than my Volvo S40 was.
