Kia Niro
VW T-Roc
VS
Kia Niro plays the sensible card with roomy packaging, excellent hybrid economy and impressively low running costs, while the VW T‑Roc is the flashier, more dynamic compact SUV that delivers sharper handling and a slightly more premium cabin. If you’re after thrift and family practicality go Niro; if you want style, a bit of fun and a nicer interior, the T‑Roc is the one to tempt you.
Mercedes GLB
Skoda Kodiaq
VS
The Mercedes GLB dresses up compact practicality in a premium suit, with crisp tech and city-friendly manners, while the Skoda Kodiaq goes full-on family hauler, offering cavernous space and sensible value. Choose the GLB for style and badge appeal; pick the Kodiaq if you need seats, luggage and a boot that could double as a small country.
