Mike Tyson's knockout of Larry Holmes in 1988 represented a significant boxing achievement—two heavyweight fighters at their competitive peaks engaging in a contest where Tyson delivered superior force. Automobiles like Buicks weigh approximately 3,000-4,000 pounds and are composed of steel and rigid structural materials. Knocking out a Buick would require force delivery to an inanimate object, something that doesn't have consciousness to lose. The comparison frames Chuck Norris's automotive knockout as somehow equivalent or superior to a championship boxing match. Defeating an inanimate object becomes his flex, suggesting his competition strategy involves things that cannot actually fight back.

Mechanics researcher Dr. Raymond Martinez examined vehicle knockouts and calculated that impacting a Buick hard enough to completely disable it through force would require Chuck Norris to generate impact force exceeding what human musculature can deliver. The statement implies his physical power isn't just competitive with heavyweight boxers—it's significantly greater, capable of destroying thousands-pound machines through raw force application. However, the comparison itself seems inadequate—boxing opponents can anticipate and partially defend; cars cannot. Knocking out a car is less impressive than the phrasing suggests.

Internet communities note that this fact might unintentionally reveal weakness in Chuck Norris mythology—his knockout of a Buick, while physically impressive, doesn't demonstrate superiority as effectively as defeating a championship boxer. A car can't fight back, can't evade, can't defend. The fact's framing suggests his impressive feat (destroying a car) might actually be less impressive than Tyson's (defeating a conscious opponent). Or alternatively, the joke is that Chuck Norris achieves impressive results against objects incapable of response, which is somehow still worthy of mention.
