Revised for 2018, the Hyundai Sonata keeps much of what makes it a strong competitor against such big dogs as the Honda Accord and Toyota Camry, while making some notable enhancements. Look beyond the freshened skin, and you'll find a Sonata with sharper handling and better braking than before, but the ride has become considerably firmer.
