ANALYSISHow safe is the 2023 Audi S4?
The 2023 Audi S4 earns a perfect 100 out of 100 on the NHTSA Safety Index, an increase from the 2022 model year's 99 out of 100. This exceptional score is notably propelled by a flawless 20 out of 20 defect record. Federal data shows no recall campaigns and no owner complaints for the 2023 S4. The vehicle also achieved a 70 out of 70 in crash protection and 10 out of 10 for avoidance technology, completing a clean sweep across all index pillars. Standard safety features include forward collision warning, lane departure warning, and electronic stability control. NHTSA's rollover test yielded a 5 out of 5 rating, with a 10 percent rollover risk and a "No Tip" result in the dynamic assessment. However, federal crash-test results for frontal and side impacts are not available, precluding a full evaluation of those protection dimensions based on federal data alone. The absence of defects reported to NHTSA distinguishes the 2023 model, even compared to its high-performing predecessor.
NCAP // CRASH TESTHow did the 2023 Audi S4 perform in crash tests?
Federal data for the 2023 Audi S4 provides a 5 out of 5 star rating for rollover protection, with a 10 percent risk of rollover and a "No Tip" result from the dynamic tip test.
