Documented as CSM 23SS0291 and identified by Shelby American as #91 of only 98 Super Snake Speedsters produced for the 2023 model year, this 2023 Ford Shelby Super Snake Speedster is one of the most exclusive expressions of the final S550-generation Mustang. Showing just 156 miles, the car combines Shelby's limited-production Speedster package with a heart-stopping 825-horsepower supercharged powertrain and and sought after Mischievous Purple Metallic finish. Accompanied by its Shelby serialization and documentation, this Speedster commemorates Carroll Shelby's 98th birthday through a production run limited to just 98 examples for the United States market.
Finished in Mischievous Purple Metallic, the car wears one of the most distinctive factory colors ever offered on a modern Mustang. Depending on lighting conditions and viewing angle, the finish transitions through shades of purple, blue, and even near-black tones, creating a dramatic color-shifting effect that recalls Ford's legendary Mystichrome models. Limited to only the 2022 and 2023 model years on the Mustang, it is a highly sought after color that is guaranteed to draw admiration.
Shelby's aggressive bodywork complements the unique finish with widened front fenders designed to accommodate a square performance tire setup, a dual-intake ram-air hood, revised front and rear fascias, and a Speedster-specific tonneau cover that gives the convertible a distinctive roadster-inspired profile. Black 20-inch forged Shelby wheels are wrapped in Michelin Pilot Sport 4S tires measuring 305mm at all four corners.
Power comes from a Shelby-enhanced 5.0L "Coyote" V8 equipped with a polished supercharger, Shelby calibration, billet throttle body, and Shelby Extreme cooling system. Output is rated at 825 horsepower, which is routed through a Ford 10R80 10-speed automatic transmission and a Ford 8.8-inch rear axle fitted with 3.55 gearing and a Torsen limited-slip differential. A Shelby-tuned Borla exhaust system featuring distinctive hexagonal outlets provides the soundtrack, while Shelby-spec Brembo brakes utilize red 6-piston front calipers and red 4-piston rear calipers.
The cabin combines modern Mustang technology with Shelby-specific craftsmanship through custom leather and Alcantara upholstery featuring 'Super Snake' embroidery. A Shelby CSM dash plaque documents the car's place within the limited-production Speedster program, while an auxiliary gauge cluster provides additional performance information. Equipment Group 401A adds premium amenities including the Ford Safe & Smart Package, adaptive cruise control, and voice-activated touchscreen navigation, creating a balance of grand touring comfort and supercar-level performance.
With just 156 miles, documented Shelby serialization, and production limited to only 98 examples, this 2023 Shelby Super Snake Speedster stands among the most exclusive Shelby Mustangs of the modern era. Its combination of 825-horsepower performance, highly uncommon Mischievous Purple Metallic paint, Speedster-specific coachwork, and Shelby documentation makes it a compelling addition to any collection focused on limited-production American performance vehicles.
