Toyota has grown the successful Prius hybrid into a family of vehicles. The new Prius C extends Toyota's proven hybrid technology into a smaller, lighter and more affordable vehicle. The smaller size and weight pays dividends in fuel efficiency. Although the Prius C is slightly larger than the Yaris 5d, its EPA rating of 53 City / 46 Hwy clearly exceeds that of the Yaris (30 City / 38 Hwy). The Prius C is a traditional 5d hatchback with a tall rear roofline (the Prius has a steeply raked fastback). The rear seat folds for hauling bulky items.
