An engineer says the engineering legacy of Holden can still be found in Cadillac's V8-powered CT5-V Blackwing, according to CarExpert. The outlet reported the claim on Saturday, 7 November 2026, framing it around the fingerprints the Australian brand left on the American performance sedan.
CarExpert did not, in the material available, identify the engineer or detail which specific components carry Holden's influence. The report's central assertion is that the defunct Australian marque's engineering work remains embedded in the CT5-V Blackwing's V8 package.
The context is Holden's long history as General Motors' Australian subsidiary, which tied its engineering operations to GM products sold globally. That relationship is the apparent basis for the engineer's remark, though CarExpert's summary does not elaborate on the technical specifics.
For readers outside Australia, Holden was a familiar name in rear-drive, V8-powered performance cars, a profile that overlaps with the CT5-V Blackwing's positioning. The report does not quantify how much of the Cadillac's development traces back to Holden personnel or facilities.
What to watch next: whether Cadillac or GM engineers elaborate publicly on Holden's contribution to the CT5-V Blackwing, and whether further reporting from CarExpert fills in the technical details behind the claim.
