These days, cars aren't just designed to be powerful or sleek. They're also designed to be eco-friendly from the ground up. Especially with Volkswagen's epic blunder, car makers are putting even more emphasis on fuel efficiency and environment friendliness. At the Chicago Auto Show, Kia is unveiling its own on the trend, blending new and old in one package. With the 2017 Optima Hybrid, the car maker is putting forward its newest fuel efficient powertrain, top of the line intelligent systems, all wrapped in a body inspired by last year's gas-powered Optima sedan.
