This is one of the S-Cross’s poorest areas, the major culprit being the 1.6-litre diesel engine. It’s noisy from idle and even at medium revs there’s a bit of clatter and vibration in the cabin. Floor the throttle and the noise reaches frustrating levels.
The 1.0 petrol is better in this respect. Press the starter button on the dashboard and the little three-cylinder engine wakes in a gruff manner, but once underway, the engine smoothes out and settles down into an almost imperceptible thrum.
However, the prize for overall refinement goes to the 1.4 petrol. At low speeds the engine is impressively smooth and silent, and even when worked hard, very little vibration is transferred to the cabin.
At high speeds on the motorway, there’s some road noise in those models with the largest alloy wheels, and some slight noise as the wind whips around the S-Cross’s door mirrors. In this respect, the Suzuki is some way behind the best-in-class Nissan Qashqai.
