Not an Arona but I bought an
Ibiza ST Ecomotive with the 1.0 95hp 3 cylinder. Coming from a 1.9 tdi Cordoba (VE), 1.9 tdi Fabia (PD) and 1.6 CR Fabia tdi, - I never liked the 1.6CR engine compared to the other two 1.9's. I was most apprehensive about the move back to petrol thinking it would be gutless and heavy on fuel. I couldn't have been more wrong. It drives much more like a diesel with plenty of low down pull and the advantage that you can hang onto a gear for longer if you get into a tight squeeze when overtaking. The fuel consumption on long distance motorway journeys is around the 60mpg (sometimes just over, sometimes just under). Generally around town it's more variable but usually well into the 40's. Spirited driving in hilly areas - where the turbo is working hard - can be a bit more expensive! So, although it lacks the sheer "animal grunt" of the 1.9 diesels I recon it goes as well as the 1.6CR and I am very happy with it.
I too like the gruff growl of the 3 cylinder but you only hear it when it's working hard. On the motorway and ticking over at traffic lights (I hate stop/start so always disable it) you really don't hear it at all. I've had the car for just over 3 years now and got 15,000 miles on the clock. So far I'm delighted although the original turbo wastegate actuator failed in the second year (there is now a modified component which was fitted under warranty and I see the newer cars all have it as standard). The only other thing which worries me a little is that the gearbox (5 speed) sounds very "loose". However it's been like this since new and there is no change in it I can notice. (I posted recently - maybe 10 days ago? - in the
Mk5 Ibiza section about this for anyone who would like to read it.)
