Mazda doesn't use turbochargers to boost the performance of its petrol engines. So, even though the 163bhp 2.0 Skyactiv-G 165 has a larger capacity and more power than the Citroën C5 Aircross 1.2 Puretech 130, it's no quicker (it does 0-62mph in 10.3sec) and nowhere near as flexible from low revs. You have to get it to 3000rpm and beyond to release its performance, which makes it harder work because you're changing down gears more often. It's also noisy but the fuel economy is pretty good.
