59 MPG City / 57 MPG Highway . The Hyundai Ioniq is the most fuel efficient car in America. With emergency roadside assistance that is free of charge, you can go anywhere! The Ioniq also looks sleek and professional, unlike other hybrid vehicles. You'll love driving the car and you'll also love the gas mileage! This car is a hatchback and has plenty of room for everything you need to pack. I have installed a state of the art Yakima roof rack so you can strap down your boards and hit the beach! DOG FRIENDLY VEHICLE! Includes seat covers for hair!
