ANALYSISHow safe is the 2021 Audi S5 Sportback?

The 2021 Audi S5 Sportback reaches the ceiling of the NHTSA Safety Index at 100 out of 100, a one-point gain over the 2020 model year's 99 out of 100. That incremental climb matters because it reflects a perfect defect record score of 20 out of 20, earned by carrying zero recall campaigns into this model year. The crash protection sub-score of 70 out of 70 and the avoidance technology sub-score of 10 out of 10 are each maxed out, the latter supported by forward collision warning, lane departure warning, and electronic stability control all arriving as standard equipment rather than optional add-ons. The one area where federal data leaves a gap is NHTSA full crash-test coverage. Overall, frontal, and side star ratings were not conducted for this vehicle. The rollover category, which was tested, produced a 5-star result with a 10 percent rollover risk figure. That single tested category is a meaningful data point, but shoppers should understand that the absence of frontal and side ratings is a gap in the public record, not a signal of either strength or weakness in those areas. The lone owner complaint, an unverified suspension allegation, does not alter the defect record score and remains an isolated, unconfirmed report in the NHTSA system.

NCAP // CRASH TESTHow did the 2021 Audi S5 Sportback perform in crash tests?

The 2021 Audi S5 Sportback earns a perfect 5 out of 5 stars in NHTSA's rollover test, with a 10 percent rollover risk and no dynamic tip result recorded. No overall, frontal, or side crash-test star ratings were assigned to this model year. The absence of frontal and side ratings indicates these protection levels remain untested by the agency.
