On sale now at Kia dealerships, the 2016 Optima received five stars in the front, side and rollover crash tests.
Standard safety equipment on the gasoline-powered 2016 Optima includes antilock brakes, electronic stability control, traction control and seven airbags, including a driver's knee airbag.
Automatic emergency braking, front collision warning and lane-departure warning are optional on the Optima SX 2.0T and standard on the Optima SXL 2.0T.
The Insurance Institute for Highway Safety has not rated the 2016 Optima.
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.
