Small overlap front — driver-side only (incomplete)
Acceptable
The 2025 IIHS coupe page carries forward a 2016 Mustang GT driver-side small-overlap test, with stated 2015-2026 applicability. IIHS labels the combined small-overlap rating incomplete: the passenger-side test is not established. This is not a new test of the 2024 redesign and does not establish convertible applicability. No completed two-sided rating or other test result is inferred.
