Kia EV6

The Kia EV6 looks like it sprinted off a concept stage, its bold, futuristic lines wrapping a surprisingly spacious and grown-up cabin. On the road it delivers crisp, immediate thrust and composed handling, with enough everyday practicality and slick tech to make ditching petrol feel like an upgrade rather than a compromise.

It drives with a confident, composed feel and somehow manages to look both rugged and refined — the grown-up SUV that still likes to have fun.
