ANALYSISHow safe is the 2021 Audi A4 Allroad?
The 2021 Audi A4 Allroad marks a two-point climb in the NHTSA Safety Index, moving from 97/100 in the 2020 model year to 99/100 in 2021, both within the Exceptional band but the 2021 version sitting closer to a perfect score. That gain is reflected in the index breakdown: crash protection at a maximum 70/70, avoidance technology at a maximum 10/10, and a defect record sub-score of 19/20. The single point separating this vehicle from a perfect defect-record score traces directly to the one active recall, a tire campaign covering a broad range of Volkswagen Group models including certain 2019-2021 Audi variants. The recall carries no urgent safety directive. The complaint record is equally restrained: one unverified allegation involving Forward Collision Avoidance, with zero reported crashes, fires, injuries, or deaths attached. NHTSA's NCAP testing is incomplete for this model year, with only the side-impact category producing a result, a full 5 out of 5 stars. The absence of frontal, overall, and rollover ratings means federal crash-test coverage is limited, but the avoidance-tech suite, including standard forward collision warning, lane departure warning, and electronic stability control, earns full credit in the index methodology. For a 2021 model year, this combination of near-perfect scoring and minimal complaint volume is genuinely distinctive.
NCAP // CRASH TESTHow did the 2021 Audi A4 Allroad perform in crash tests?
