This Performance-E STI Concept from Subaru looks to the future of what a fully electric hot hatch could look like. With no specs to look at, our attention lands solely on the styling and design. And on that front, Subaru have delivered a striking looking concept that would take pride of place on the bedroom wall of many youngsters. The wheel arches are wide, rear wing big, diffuser large and the profile is sharp in all the right ways.
