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.

I love this car — it moves super fast, makes me feel safe and wonderfully agile, like it’s got the power of a gasoline V8.

Great for city and recreational driving. Highway speeds and winter reveal its appetite for electricity — range drops quickly. The low beams could be brighter; the high beam is potent! Other than that, the car really pampers you.
