What did KR stand for in the 1968 Shelby GT500KR name?
Answer
King of the Road
KR stood for “King of the Road” in the 1968 Shelby GT500KR name.
The designation appeared when Ford introduced the Cobra Jet version of its 428-cubic-inch V8 in 1968. The higher-performance engine led to the GT500 being renamed the Cobra GT500KR, with “KR” distinguishing it from the earlier GT500.
The Cobra Jet was officially rated at 335 horsepower but produced 440 lb-ft of torque. Those figures helped establish the GT500KR as one of the most powerful factory Mustangs of its era. Ford and Shelby used “King of the Road” as a boastful performance title, not as an abbreviation for a racing program.
The name can cause confusion because “Knight Rider” is also associated with a later Shelby GT500KR. A black 2008–09 GT500KR appeared as KITT in the television reboot, but that connection came decades after the original 1968 model.
