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.
