What the ratings mean
NHTSA gives the 2015 Kia Optima 5 out of 5 stars overall, level with the 5-star median for the 21 comparable 2015 vehicles NHTSA rated in this class.
NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.
NHTSA's dynamic test put this vehicle's rollover probability at 9.6% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.

How this compares
At 24 MPG combined, the 2015 Kia Optima ranks 12th of 23 midsize cars EPA rated for 2015 — exactly the 24 MPG median for that group.
That places it a little below the middle of its class. If annual mileage is high, the running-cost gap against a class-average rival compounds quickly.
EPA puts annual fuel spend at about $2,550, within $0 of the $2,550 typical for the class — roughly $12,750 over five years.
Tailpipe CO₂ is 372 grams per mile — about 5.6 metric tons over 15,000 miles of driving.
