smart #3

The Smart #3 turns the brand's cheeky city-car attitude into a grown-up compact SUV, pairing sleek styling with a surprisingly roomy, well-made interior. It's a brilliant pick for buyers who want electric ease without dullness — practical enough for daily life, but still lively enough to make parking and grocery runs feel a little fun.

details

Subaru Uncharted

The Subaru Uncharted is a compact electric crossover that feels at home in the city, with easy steering and Subaru’s traction helpers giving it more off‑road composure than its size suggests. It’s practical and simple to use for daily life with convenient charging, but the rear seat is snug, rear visibility suffers without a wiper, and the all‑wheel‑drive version can be thirstier on long motorway runs.
