Its initials stood for King of the Road, and if the 1968ShelbyCobra GT 500-KR looked like a more threateningmuscle carthan it really was, so be it.
Shelby's 1967 GT 500 had ledFord's pony car across the 400-cid threshold with a 427-cid detuned raceengineand a juiced 428-cid Police Interceptor V-8. Both returned for '68. Then in April '68, Ford unveiled an even-hotter version of the 428, theCobra Jet, and offered it in the Mustang, among other models.

At Shelby, the Cobra Jet replaced the original 428, and GT 500s gained a KR suffix, for King of the Road. (The 427 was dropped.) This was the year's second name change. Shelby's AC Cobra roadster died after '67, but he kept the name, rechristening his Mustangs the Shelby Cobra GT 500 and Shelby Cobra GT 350. (The GT 350 for '68 used Ford's new 302-cid V-8 and was rated at 250 bhp.)
The GT 500-KR's 428 had the same suspiciously low 335-bhp rating as other Cobra Jets, though some Shelby material put peak output at higher rpm. Shelby's version had diecast aluminum Cobra rocker covers but wore the same plain painted ram-air air cleaner.
Plain did not describe the GT 500-KR. This was the first year for a Shelbyconvertible, and like the fastback, it dressed up the stock Mustang with its own fiberglass nose panels, fiberglass hood with working scoops and air-extraction vents, decorative bodyside intakes, and a spoilered tail with sequentialturn signals. The fastback's roof scoops directed air to the cabin. A paddedroll bar附加惯性卷筒肩带,即兴表演ved gauges, and woodgrain appliques marked the otherwise stock-Mustang interior.
With its fattiresandsuspensiontweaks, the GT 500-KR out handled all but pure sports cars. But it weighed more than a Cobra Jet Mustang, and as a drag racer, it was no Hemi-hunter. To most street rivals, however, one look was all it took. "Oddly, the KR's vincibility doesn't matter," observed Car Life. "Thecaris so impressive, so intimidating to challengers, that there are no challengers. The KR breeds confidence bordering on arrogance."
