2009-2010 Ford Mustang Convertible V (facelift ) GT 4.6 V8 (315 Hp)

The Ford Mustang Convertible V, specifically the facelifted version produced from 2009 to 2010, represented a continuation of the fifth-generation (S197) Mustang. This iteration, characterized by revised styling cues and updated features, offered a compelling blend of performance and open-air driving enjoyment. The GT model, equipped with the 4.6-liter Modular V8 engine producing 315 horsepower, occupied a premium position within the Convertible lineup, serving as the performance-oriented choice for buyers seeking a more exhilarating driving experience compared to the base V6 models. It was positioned as a step up from the V6, offering significantly more power and a more aggressive character, but remained below the later, more powerful Coyote V8-equipped Mustangs.

The 2009-2010 Mustang GT Convertible: A Detailed Overview

The 2009-2010 Mustang Convertible V GT was a direct response to market demand for a powerful, stylish, and accessible American sports car. The facelift brought subtle but noticeable changes to the exterior, including a revised grille, headlights, and taillights, giving the car a more modern and refined appearance. The interior also received minor updates, focusing on improved materials and ergonomics. However, the core appeal remained the potent 4.6-liter V8 engine and the freedom of a retractable soft top.

Powertrain & Engine Architecture

At the heart of the 2009-2010 Mustang GT Convertible lay Ford’s 4.6-liter Modular V8 engine, internally designated as the 4.6L 2V. This engine, a staple of the Mustang lineup for many years, was a three-valve-per-cylinder (2V refers to two valves per cylinder bank) design, utilizing a single overhead camshaft (SOHC) configuration. The engine produced 315 horsepower at 6000 rpm and 441 Nm (325.26 lb-ft) of torque at 4250 rpm. Fuel delivery was managed by a multi-port fuel injection system, ensuring precise fuel metering for optimal performance and efficiency. The engine’s bore and stroke measured 90.2 mm (3.55 in) and 90 mm (3.54 in) respectively, resulting in a displacement of 4601 cm³ (280.77 cu. in). The compression ratio was set at 9.8:1. The engine oil capacity was 5.7 liters (6.02 US qt / 5.02 UK qt), and Ford specified a particular oil grade for optimal lubrication and protection.

While a five-speed manual transmission was available, the focus of this article is the automatic transmission variant. The Mustang GT Convertible utilized a five-speed automatic transmission, designed to provide smooth and convenient shifting. The transmission was electronically controlled, adapting shift points based on driving conditions and throttle input. The gear ratios were tuned to balance acceleration and fuel economy, with a focus on delivering usable torque for everyday driving and spirited performance.

Driving Characteristics

The 2009-2010 Mustang GT Convertible, equipped with the automatic transmission, offered a distinct driving experience compared to its manual counterpart and the V6 models. The automatic transmission provided a more relaxed and comfortable driving experience, particularly in urban traffic. While the manual transmission offered more driver engagement and control, the automatic delivered smooth and predictable shifts, making it an ideal choice for drivers prioritizing convenience. The 4.6-liter V8 provided ample power for confident acceleration and passing maneuvers. The rear-wheel-drive configuration contributed to a balanced and engaging driving feel, although it required careful throttle control in adverse weather conditions. The convertible top, while adding some weight, did not significantly detract from the car’s handling characteristics. The suspension, tuned for a balance of comfort and performance, provided a reasonably compliant ride without sacrificing cornering stability.

Equipment & Trim Levels

The Mustang GT Convertible came standard with a comprehensive list of features, reflecting its position as the premium trim level. Standard equipment included air conditioning, power windows and locks, a premium sound system, and alloy wheels. The interior featured comfortable cloth seats, although leather upholstery was available as an option. The dashboard was equipped with analog gauges, providing essential information to the driver. Optional extras included a power-adjustable driver’s seat, a Shaker audio system, and a color-keyed hardtop for added weather protection. The GT package also included unique exterior styling cues, such as a rear spoiler and fog lamps.

Chassis & Braking

The 2009-2010 Mustang GT Convertible utilized an independent front suspension with McPherson struts and a transverse stabilizer bar. The rear suspension employed a solid axle configuration with coil springs and a transverse stabilizer bar. This setup provided a good balance of ride comfort and handling performance. The braking system consisted of ventilated discs at all four wheels, providing ample stopping power. The front brakes measured 316×30 mm, while the rear brakes were slightly smaller at 300×19 mm. An Anti-lock Braking System (ABS) was standard, enhancing safety and control during emergency braking situations. The steering system was a hydraulic rack and pinion setup, providing precise and responsive steering feel.

Market Reception & Comparison

The 2009-2010 Mustang GT Convertible was generally well-received by automotive critics and consumers alike. It was praised for its powerful V8 engine, stylish design, and relatively affordable price point. Compared to the base V6 models, the GT offered a significant performance upgrade, making it a more appealing choice for enthusiasts. However, some critics noted that the interior materials were not as refined as those found in some competing sports cars. In terms of fuel economy, the GT Convertible was less efficient than the V6 models, achieving approximately 14.7 l/100 km (16 US mpg / 19.2 UK mpg) in urban driving and 9.8 l/100 km (24 US mpg / 28.8 UK mpg) on the highway. Reliability was generally good, although some owners reported minor issues with the automatic transmission and convertible top mechanism.

Today, these cars can be found on the used car market at reasonable prices, offering a compelling combination of performance, style, and open-air driving enjoyment. The automatic transmission variant, while not as sought after as the manual, provides a more accessible and convenient driving experience for a wider range of buyers.
