Its design is edgier, its handling sharper, its safety tech leads the class, and a hybrid drivetrain is available at all specification levels. And it’s more expensive. But if Toyota really wants to stake its claim as the best small car, it needs to get past the ageless champion – Volkswagen's Golf.
