For 2015, Ford will split production of the Shelby GT350 in half with 50 models featuring the Track Package and 50 models featuring the Technology Package. While not specified, each of the 37 Shelby GT350R models will likely be identically equipped. Expect options to be limited to paint colors. Each 2015 Shelby model will receive a unique 2015 VIN sequence. Shelby models built after the initial 137 model run will be 2016 model-year vehicles.

Ford claims the 2015 Shelby GT350 and Shelby GT350R will feature the automaker's most powerful naturally aspirated engine ever built. While few details are known, the Shelby models will be powered by a 5.2-liter flat-plane-crank V-8 making more than 500 hp and 400 lb-ft of torque. The 5.0-liter Coyote V-8 in the 2015 Ford Mustang GT makes 435 hp and 400 lb-ft.

"Fans of the Shelby brand are among the most passionate in the automotive industry," said Henry Ford III, Ford Performance marketing manager, in a release. "To honor the passion of our fans for Shelby GT350's 50th anniversary, a limited run of GT350 models will be built in 2015; these cars will be highly coveted by both Mustang and Shelby enthusiasts alike."

Production of the Shelby GT350R will commemorate the original FIA-homologated Mustang called the Shelby GT350 competition model developed by Carroll Shelby in 1965. The cars participated in many global races, including the 1967 24 Hours of Le Mans, and even won the Sports Car Club of America's B Production national championship in 1965, 1966, and 1967.

According to Carroll Shelby, two prototypes and 35 production models were built, most records suggest only 34 cars had Shelby serial numbers. Regardless of the actual number, Ford is building 37 Shelby GT350R models to honor the man behind the original car.
