What the ratings mean
NHTSA gives the 2018 Acura RLX 5 out of 5 stars overall, level with the 5-star median for the 16 comparable 2018 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 9.7% 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 23 MPG combined, the 2018 Acura RLX ranks 19th of 24 midsize cars EPA rated for 2018 — 3.5 MPG short of the 26.5 MPG median for that group.
That places it among the thirstiest vehicles in 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 $3,300, $700 more than the $2,600 typical for the class. Over five years at 15,000 miles a year that is roughly $16,500, a $3,500 difference against a class-median vehicle.
Tailpipe CO₂ is 383 grams per mile — about 5.7 metric tons over 15,000 miles of driving.
