text: 2008–2009 GT500KR The Ford Shelby GT500KR, revealed at the 2007 New York International Auto Show, was released in the spring of 2008. The car is powered by a Modular  supercharged and intercooled version of the base GT500 V8 engine now upgraded to  at 6,250 rpm and  at 4,500 rpm of torque with functional Cold Air Intake and unique calibration. SVT and Shelby announced that 1,000 40th Anniversary Editions would be built for the U.S. in 2008, with another 571 units in 2009. This 1,571 production run matches that of the original 1968 GT500KR. In total, 1,712 units were produced, with the remaining units going to Canada, export markets and military sales.
  All KRs were built by AutoAlliance International on the normal Mustang production line and then shipped to Shelby Automobiles Incorporated (SAI) where final assembly was completed.
  The Shelby GT500KR features a carbon fiber composite hood with functional scoops and vents, twist-lock hood pins modeled on the original 1968 KR, a unique carbon fiber splitter, carbon fiber mirror caps, and functional brake cooling ducts. The suspension was tuned by SVT with unique spring rates, dampers, stabilizer bars, and strut tower brace and was sourced from Ford Racing. Unique Goodyear Eagle F1 Supercar tires were developed for the KR with a unique compound. With the same tread pattern as the Eagle F1 Supercar tire on the 2007–2009 GT500 they can only be identified by a unique Goodyear "Wingedfoot" emblem on the sidewall.
  The 2008–09 GT500KR draws on styling cues from the classic 1968 "King of the Road" GT500KR model, and the 2008 model includes "40th Anniversary" badging; both years will have availability of standard GT500 colors with "LeMans" stripes, and Carroll Shelby signature embroidered seats. The GT500KR's starting price was $120,000.
