The Ford Mustang Convertible VI, specifically the facelifted version from 2017, equipped with the potent GT/CS 5.0 V8 engine producing 450 horsepower, represents a significant chapter in the iconic Mustang’s history. Produced between March 2022 and 2023, this variant embodies the California Special (GT/CS) package, blending classic Mustang aesthetics with contemporary performance and open-air driving. Positioned in the performance convertible segment, it offers a compelling combination of raw power, distinctive styling, and modern amenities, appealing to drivers seeking a visceral American driving experience. The sixth generation Mustang, introduced in 2015, was a pivotal moment for the pony car, featuring an independent rear suspension across the entire lineup and a more globally-focused design.
Powertrain & Engine Architecture
At the heart of the Ford Mustang Convertible VI (facelift 2017) GT/CS lies the 5.0-liter “Coyote” V8 engine, a naturally aspirated powerhouse renowned for its high-revving character and robust output. This iteration delivers 450 horsepower at 7000 rpm and 390.17 lb-ft of torque peaking at 4600 rpm. The Coyote V8 utilizes a dual-fuel injection system, combining direct injection with multi-port manifold injection for optimized fuel delivery and enhanced power and efficiency. A compression ratio of 12:1 and a DOHC (Dual Overhead Camshaft) valvetrain with TIVCT (Twin Independent Variable Cam Timing) further maximize volumetric efficiency and precise valve control. The engine also incorporates modern efficiency technologies like a Start & Stop system and a particulate filter to meet stringent Euro 6d emission standards.
Power is transferred to the rear wheels through a precise 6-speed manual transmission, offering an engaging and direct driving experience. The rear-wheel-drive architecture is fundamental to the Mustang’s character, providing classic muscle car dynamics. The engine is longitudinally mounted in the front of the vehicle. The 6-speed manual transmission provides a traditional gear selection experience, favored by driving enthusiasts.
Driving Characteristics
The 450 hp / 6-speed manual combination in the Mustang Convertible GT/CS delivers exhilarating performance. Acceleration from 0 to 60 mph is achieved in approximately 4.6 seconds, with an electronically limited top speed of 154.72 mph. Compared to lower-output Mustang variants, the GT/CS offers a significantly more potent driving experience. The Coyote V8’s torque curve provides strong acceleration throughout the rev range, making it responsive in various driving situations. While the manual transmission offers greater driver control, the overall driving experience is characterized by a balance of raw power and modern refinement. The independent rear suspension contributes to improved handling and stability compared to earlier Mustang generations.
The 6-speed manual transmission’s gear ratios are tuned to maximize acceleration and provide a sporty driving feel. First gear is relatively short, providing quick off-the-line acceleration, while higher gears are optimized for cruising efficiency. The power delivery is linear and predictable, making it easy for drivers to modulate the throttle and maintain control. Compared to automatic transmission options, the manual transmission offers a more engaging and connected driving experience, allowing drivers to fully exploit the engine’s capabilities.
Equipment & Trim Levels
The GT/CS package adds unique styling elements to the standard Mustang Convertible. These include distinctive five-spoke wheels, a more prominent front splitter, side scoops, and specific badging. Inside, the GT/CS typically features unique upholstery options, special badging on the dashboard and seats, and contrast stitching. Standard features include automatic climate control, power-adjustable seats, and a premium audio system. The facelifted 2017 model introduced a digital instrument cluster, providing customizable displays for various driving modes. The infotainment system, Ford’s SYNC 3 or later, offers a touchscreen interface with navigation, smartphone integration (Apple CarPlay and Android Auto), and voice commands. Optional extras could include upgraded sound systems, leather upholstery, and advanced driver-assistance features.
The Mustang Convertible GT/CS was positioned as a premium trim level within the Mustang lineup, offering a more exclusive and performance-oriented experience than the base EcoBoost models. It catered to buyers who desired the open-air driving experience of a convertible combined with the power and prestige of a V8 engine and the unique styling cues of the California Special package.
Chassis & Braking
The Mustang Convertible utilizes a sophisticated chassis designed for both performance and ride comfort. The front suspension employs an independent McPherson strut setup with coil springs and an anti-roll bar, while the rear features an independent multi-link spring suspension with a stabilizer bar. This independent rear suspension, a significant upgrade for the sixth generation, greatly improves handling, ride quality, and traction. Braking performance is provided by large ventilated discs at both the front (380×34 mm) and rear (330×25 mm), coupled with ABS (Anti-lock Braking System) for confident stopping power. The electric power steering system provides precise feedback and adjustable settings. The convertible body structure incorporates additional bracing to maintain rigidity and minimize chassis flex.
The suspension tuning is geared towards providing a balance between sporty handling and comfortable ride quality. The stabilizer bars help to reduce body roll during cornering, while the coil springs and dampers are calibrated to absorb bumps and irregularities in the road surface. The braking system is designed to provide consistent and reliable stopping power, even under demanding conditions.
Market Reception & Comparison
Critics generally praised the Ford Mustang Convertible VI (facelift 2017) GT/CS for its powerful engine, engaging driving dynamics, and distinctive styling. The Coyote V8 received particular acclaim for its responsiveness and exhilarating performance. The independent rear suspension was also lauded for improving handling and ride quality compared to previous generations. Fuel economy was considered reasonable for a high-performance V8 convertible, with combined fuel consumption ranging from 19.9 to 19.4 US mpg (WLTP). Reliability was generally good, although some owners reported minor issues with the infotainment system.
Compared to other trims in the Mustang lineup, the GT/CS offered a more exclusive and performance-focused experience. The EcoBoost models provided better fuel economy but lacked the power and prestige of the V8. The higher-performance Shelby GT350 offered even more track-focused performance but came at a significantly higher price point. Against competitors like the Chevrolet Camaro Convertible, the Mustang GT/CS was often seen as offering a more refined and comfortable driving experience, while the Camaro was praised for its sharper handling.
