The Ford Mustang Convertible VI (facelift 2017) GT 5.0 Ti-VCT V8 (460 Hp) SelectShift represents a significant evolution of the iconic American pony car. Produced from 2017 to 2021, this facelifted convertible blended classic Mustang styling with modern performance and technology, offering an exhilarating open-air driving experience powered by a potent V8 engine. Positioned as a premium performance variant within the sixth-generation Mustang lineup (S550), it appealed to drivers seeking a combination of raw power, iconic design, and a touch of luxury. This model built upon the foundation laid by the initial S550 launch in 2015, incorporating refinements to both the exterior and interior, as well as improvements to the powertrain.
Powertrain & Engine Architecture
The heart of the Mustang GT Convertible is the “Coyote” 5.0-liter V8 engine. This naturally aspirated powerplant, internally designated as the Coyote, boasts a displacement of 4949 cubic centimeters (302.01 cubic inches). A key feature of the Coyote engine is its Ti-VCT (Twin Independent Variable Cam Timing) system. This advanced valvetrain technology allows for independent control of both intake and exhaust camshaft timing, optimizing valve overlap across the engine’s RPM range. This results in improved power delivery, enhanced fuel efficiency, and reduced emissions. The engine utilizes multi-port fuel injection for precise fuel delivery.
For the 2017 facelift, Ford engineers increased the Coyote V8’s output to 460 horsepower at 5500 rpm and 419.67 lb-ft (569 Nm) of torque at 4600 rpm. This power is channeled to the rear wheels through a 10-speed SelectShift automatic transmission. This transmission, co-developed with General Motors, was a substantial upgrade over previous Mustang automatics. It features a wide range of gear ratios, enabling quicker acceleration, improved fuel economy, and optimized engine performance in various driving conditions. The transmission offers both fully automatic operation and manual control via paddle shifters, allowing drivers to tailor the driving experience to their preferences.
Driving Characteristics
The combination of the 460 hp Coyote V8 and the 10-speed automatic transmission delivers a dynamic and engaging driving experience. The Mustang GT Convertible offers brisk acceleration, with a 0-60 mph time typically in the low 4-second range. The 10-speed transmission’s closely spaced gear ratios keep the engine within its optimal power band, providing strong pull throughout the RPM range. Compared to the manual transmission-equipped Mustang GT, the automatic version offers slightly slower acceleration due to inherent transmission losses, but provides greater convenience and ease of use, particularly in everyday driving situations. The power-to-weight ratio of 259.7 hp per tonne contributes to a lively and responsive feel, despite the convertible’s added weight compared to the coupe.
The Mustang GT Convertible’s handling is significantly improved over previous generations thanks to its independent rear suspension. While not as track-focused as the Mustang GT with the Performance Pack, the standard suspension provides a comfortable ride and predictable handling characteristics. The steering is responsive and well-weighted, offering good feedback to the driver. The convertible top, while adding weight, does not significantly compromise the car’s handling balance.
Equipment & Trim Levels
The 2017-2021 Mustang GT Convertible came standard with a comprehensive list of features. Interior appointments typically included leather-trimmed seats, a leather-wrapped steering wheel, and aluminum pedal covers. Standard technology features included Ford’s SYNC 3 infotainment system with an 8-inch touchscreen display, Bluetooth connectivity, and a premium sound system. Safety features included anti-lock brakes, traction control, stability control, and a rearview camera.
Optional extras were plentiful, allowing buyers to customize their Mustang GT Convertible to their liking. Popular options included the Premium Package, which added features such as heated and cooled front seats, upgraded leather upholstery, and a navigation system. Other available options included a blind-spot monitoring system, adaptive cruise control, and a power-adjustable steering column. Exterior options included various wheel designs, paint colors, and stripe packages.
Chassis & Braking
The Mustang GT Convertible utilizes a McPherson strut front suspension with coil springs and an anti-roll bar. The rear suspension is an independent multi-link setup, also with coil springs and a stabilizer bar. This independent rear suspension, a first for the Mustang, significantly improved ride quality and handling compared to previous generations that used a solid rear axle. The chassis is reinforced to compensate for the structural changes required for the convertible top.
Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The Anti-lock Braking System (ABS) is standard, enhancing safety and control during hard braking maneuvers. The braking system is tuned to provide a firm pedal feel and consistent performance. The standard wheel size is 18 inches, with performance tires available as an option for improved grip.
Market Reception & Comparison
The 2017-2021 Ford Mustang GT Convertible was generally well-received by automotive critics. Reviewers praised its powerful V8 engine, improved handling, and refined interior. The 10-speed automatic transmission was also lauded for its smooth shifting and responsiveness. Compared to the Mustang EcoBoost (turbocharged four-cylinder) and the V6 models, the GT Convertible offered a significantly more engaging driving experience and a more prestigious image.
In comparison to its rivals, the Chevrolet Camaro Convertible and the Dodge Challenger, the Mustang GT Convertible offered a compelling blend of performance, style, and value. The Camaro was often praised for its sharper handling, while the Challenger offered more interior space and a retro-inspired design. The Mustang GT Convertible struck a balance between these two, offering a sporty driving experience and a classic Mustang aesthetic. Fuel economy, at 18.1 US mpg combined, was comparable to its competitors, though not a primary focus for this type of vehicle. Reliability was generally good, with the Coyote V8 proving to be a durable and dependable engine.
