Ford Mustang Convertible VI (facelift 2017) GT/CS 5.0 V8 (450 Hp) SelectShift: A Modern American Icon
The Ford Mustang, a name synonymous with American automotive culture, continued its storied legacy with the sixth-generation model, introduced in 2015. The focus of this article is the updated, post-facelift variant, specifically the Ford Mustang Convertible VI (facelift 2017) GT/CS 5.0 V8 (450 Hp) SelectShift, produced from March 2022 to 2023. This particular iteration represents a potent blend of classic muscle car aesthetics, modern performance, and open-air driving excitement. As a two-door, four-seat cabriolet, it firmly occupies the sporty convertible segment, appealing to enthusiasts seeking both visceral performance and an iconic driving experience. The GT/CS designation, signifying “California Special,” adds a layer of heritage and unique styling cues, enhancing its appeal as a collectible and desirable model within the Mustang lineup.
The sixth-generation Mustang marked a significant turning point for the pony car, introducing independent rear suspension across the board for improved handling and comfort, a feature long requested by enthusiasts and critics alike. The 2017 facelift further refined the model with updated styling, enhanced technology, and, crucially for the GT, a more powerful rendition of its legendary 5.0-liter Coyote V8 engine. This specific GT/CS Convertible variant, with its 450 horsepower and advanced 10-speed SelectShift automatic transmission, stands as a testament to Ford’s commitment to evolving the Mustang while staying true to its roots as an accessible, high-performance sports car.
Engine & Performance of the Ford Mustang Convertible VI (facelift 2017) GT/CS 5.0 V8 (450 Hp) SelectShift
At the heart of the Ford Mustang Convertible VI (facelift 2017) GT/CS 5.0 V8 (450 Hp) SelectShift lies the formidable “Coyote” 5.0-liter V8 engine, an engineering marvel that delivers both raw power and a thrilling auditory experience. This naturally aspirated powerhouse is longitudinally mounted in the front, driving the rear wheels, a classic muscle car configuration. With a displacement of 5038 cm3 (307.44 cu. in.), it produces an impressive 450 horsepower at a screaming 7000 rpm, translating to a power-per-liter output of 89.3 Hp/l. Torque figures are equally impressive, peaking at 390.17 lb.-ft. (529 Nm) at 4600 rpm, ensuring robust acceleration across the rev range.
The engine incorporates advanced technologies such as direct injection and multi-port manifold injection, combined with a DOHC (Dual Overhead Camshaft) valvetrain featuring Twin Independent Variable Cam Timing (TIVCT). This sophisticated setup optimizes combustion efficiency and power delivery, while maintaining compliance with Euro 6d emission standards. The compression ratio stands at a high 12:1, indicative of its performance-oriented design. Fueling this beast requires gasoline (petrol), and the engine is equipped with a Start & Stop system and a particulate filter to enhance efficiency and reduce emissions, a nod to modern environmental considerations even in a high-performance vehicle.
Power is channeled through a state-of-the-art 10-speed SelectShift automatic transmission. This gearbox, co-developed by Ford and General Motors, offers rapid, smooth shifts and contributes significantly to the car’s impressive acceleration. The sprint from 0 to 60 mph is achieved in a blistering 4.3 seconds (calculated by Auto-Data.net), while 0 to 100 km/h takes 4.5 seconds. The top speed is electronically limited to 154.72 mph (249 km/h). Despite its potent performance, the combined fuel consumption (WLTP) is rated between 21 and 20.3 US mpg (11.2-11.6 l/100 km), which is respectable for a car of its power and weight, which comes in at 3842.66 lbs (1743 kg) curb weight. The weight-to-power ratio of 3.9 kg/Hp (258.2 Hp/tonne) further underscores its performance capabilities.
Design & Features: The California Special Convertible
The Ford Mustang Convertible VI (facelift 2017) GT/CS 5.0 V8 (450 Hp) SelectShift embodies a timeless design language, masterfully blending classic Mustang cues with contemporary styling. As a cabriolet, its defining feature is the power-retractable soft top, allowing occupants to experience open-air exhilaration. The facelift introduced sharper lines, revised front and rear fascias, and updated lighting signatures, giving the Mustang a more aggressive and modern stance while retaining its iconic pony car profile.
The GT/CS, or California Special, package elevates the Mustang’s aesthetic with unique design elements that pay homage to a special edition from the late 1960s. These typically include distinctive blacked-out grille, unique side stripes, special badging, a prominent rear spoiler, and unique five-spoke alloy wheels. For this 2022-2023 model, the front wheel tires are 255/40 R19, paired with 9J x 19 rims, while the rear features wider 275/40 R19 tires on 9.5J x 19 rims, emphasizing its rear-wheel-drive performance nature.
Inside, the Mustang GT/CS Convertible offers a driver-focused cockpit with seating for four. While the rear seats are more suitable for occasional use, the front cabin provides ample space and comfort. Modern Mustangs are equipped with advanced infotainment systems, premium materials, and a host of driver-assistance features. The 2017 facelift brought an optional 12-inch digital instrument cluster, configurable drive modes, and enhanced connectivity options, including Apple CarPlay and Android Auto integration. Safety features for a modern car like this include a robust chassis, multiple airbags, and an Anti-lock Braking System (ABS), which complements the powerful ventilated disc brakes (380×34 mm front, 330×25 mm rear).
Dimensionally, the vehicle measures 188.54 inches (4789 mm) in length, 75.43 inches (1916 mm) in width (81.93 inches including mirrors), and 54.96 inches (1396 mm) in height. The wheelbase of 107.09 inches (2720 mm) contributes to its stable handling, while the minimum turning circle of 40.03 feet (12.2 m) provides decent maneuverability. The trunk space is a respectable 11.72 cu. ft. (332 liters), offering enough room for weekend getaways, even with the convertible top mechanism.

Legacy & Market Impact
The Ford Mustang holds an indelible place in automotive history, pioneering the “pony car” segment and becoming a global symbol of American performance and freedom. The sixth-generation Mustang, especially its post-facelift GT/CS Convertible variant, continues this legacy, adapting to modern demands while retaining its core identity. Its role in the American market is paramount; it’s a direct competitor to other iconic muscle cars like the Chevrolet Camaro and Dodge Challenger, offering a distinct blend of heritage, performance, and everyday usability.
The GT/CS (California Special) trim level itself carries significant historical weight. Originating in 1968 as a limited-production model, it was inspired by a Shelby GT prototype and offered unique styling cues. Its reappearance on modern Mustangs, including this 2022-2023 convertible, connects contemporary buyers with that rich heritage, offering a distinctive package that stands out from a standard GT. This blend of historical significance and modern performance makes the Ford Mustang Convertible VI (facelift 2017) GT/CS 5.0 V8 (450 Hp) SelectShift particularly appealing to collectors and enthusiasts alike.
Beyond its domestic appeal, the sixth-generation Mustang was the first to be truly engineered for global markets, with right-hand drive versions and European-specific tuning. While the GT/CS itself is primarily a North American offering, the underlying platform and powertrain contributed to the Mustang’s global success, expanding its cultural footprint far beyond American borders. Its combination of a powerful naturally aspirated V8, sophisticated independent suspension, and the allure of open-top driving ensures its continued relevance in a rapidly evolving automotive landscape, even as the industry shifts towards electrification. The Mustang GT/CS Convertible serves as a powerful reminder of the enduring appeal of traditional American muscle.
