Just add AEB
The Europe-market Kia Stonic – the Rio’s SUV sister – gives a good indication of how small changes make a huge difference to crash-test scores. The standard car rates three stars despite respectable scores in both ‘adult occupant’ and ‘child occupant’. The ‘safety pack’ car that has been tested separately – and which adds AEB and lane-departure warning – scores five stars, with the auto-braking boosting its ‘adult occupant’ and ‘pedestrian scores’ as well as ‘safety assist’. In every other regard it’s the same car.
