What the ratings mean

NHTSA gives the 2020 Audi A4 5 out of 5 stars overall, level with the 5-star median for the 10 comparable 2020 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 9.9% 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 30 MPG combined, the 2020 Audi A4 ranks 9th of 18 compact cars EPA rated for 2020 — exactly the 30 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, $475 more than the $2,075 typical for the class. Over five years at 15,000 miles a year that is roughly $12,750, a $2,375 difference against a class-median vehicle.

Tailpipe CO₂ is 295 grams per mile — about 4.4 metric tons over 15,000 miles of driving.
