Engines seem to be noisier nowadays, last week I had a Vauxhall Astra 1.0 turbo petrol hire car, it drove well but was so noisy I was convinced it was a diesel till I refuelled it to hand it back, I also found Ford Ecoboost engines to be quiet raucous, I also found you had to work them fairly hard to unleash the power, so all in, not much difference from the latest Jazz really.
