On sale now at Hyundai dealerships, the mildly revised 2016 Sonata received five stars in the front and side crash tests and four stars in the rollover crash test.
The rating also applies to the 2016 Hyundai Sonata Hybrid.
Standard safety features on the carryover 2016 Sonata include antilock brakes, traction control, electronic stability control and seven airbags, including a driver's knee airbag.
Automatic emergency braking is added on Sonata models previously equipped with forward-collision warning.
Edmunds says: Car shoppers keeping score should note that the 2016 Ford Fusion, Honda Accord and Toyota Camry also earned the highest five-star overall safety rating from NHTSA.
