The Ford Mustang Convertible V 4.6 i V8 24V (304 Hp) represents a significant iteration of the iconic Mustang, produced between 2005 and 2009. This model year marked the return of some classic Mustang styling cues, blending retro aesthetics with modern engineering. Within the fifth generation (S197) Mustang lineup, this variant occupied a mid-range position, offering a substantial performance upgrade over the base V6 models while remaining more accessible than the higher-performance GT versions with manual transmissions. It catered to buyers seeking open-air driving enjoyment coupled with a robust V8 engine.
Powertrain & Engine Architecture
At the heart of the Mustang Convertible V 4.6 i is Ford’s Modular 4.6-liter V8 engine, specifically the version designated for 304 horsepower. This engine, internally known as the 2V due to its two valves per cylinder, is a 90-degree V-engine constructed with an iron block and aluminum cylinder heads. The engine code is generally associated with the broader Modular engine family, but specific variations existed within the 2005-2009 timeframe. The 4.6L engine utilizes a multi-port fuel injection system, delivering fuel directly into the intake ports just before the intake valves. This system, while not as advanced as direct injection, provided reliable and consistent fuel delivery for the engine’s power output.
The valvetrain employs three valves per cylinder (two intake, one exhaust) actuated by single overhead camshafts (SOHC). This configuration balanced performance and cost-effectiveness. The engine’s 9.8:1 compression ratio contributed to its torque output and responsiveness. The 2005-2009 Mustang Convertible V 4.6 i was exclusively offered with a 5-speed automatic transmission. This transmission was designed to handle the engine’s 304 hp and 320 lb-ft of torque, providing smooth shifts and a comfortable driving experience. The automatic transmission featured electronic controls for optimized shift points and responsiveness.
Transmission Details
The 5-speed automatic transmission used in this Mustang variant is a Ford-designed unit, known for its durability and relatively smooth operation. Gear ratios were tuned to balance acceleration and fuel economy. First gear was geared for strong off-the-line acceleration, while higher gears were optimized for highway cruising. While not as sporty as a manual transmission, the automatic offered convenience and ease of use, appealing to a broader range of drivers.
Driving Characteristics
The 2005-2009 Mustang Convertible V 4.6 i delivered a distinctly American driving experience. The 4.6L V8 provided ample low-end torque, making it responsive in everyday driving situations. Acceleration from 0 to 60 mph was consistently achieved in around 5.3 seconds, a respectable figure for a convertible of its era. Compared to the manual transmission-equipped GT models, the automatic version offered slightly slower acceleration due to inherent transmission losses. However, the automatic provided a more relaxed and refined driving experience, particularly in city traffic.
The convertible top added weight to the vehicle, impacting handling slightly compared to the coupe. However, the Mustang’s rear-wheel-drive layout and well-tuned suspension provided a reasonably engaging driving experience. The steering was responsive, and the car felt planted on the road. The automatic transmission’s shift points were generally well-chosen, providing smooth transitions between gears. Overall, the driving experience was characterized by a blend of power, comfort, and open-air enjoyment.
Equipment & Trim Levels
The Mustang Convertible V 4.6 i came standard with a range of features designed to enhance comfort and convenience. Standard interior features included cloth upholstery, air conditioning, power windows and locks, and a basic audio system. Optional extras included leather upholstery, upgraded audio systems (including Shaker audio systems), power-adjustable seats, and a color-keyed hardtop for added weather protection. The dashboard layout was relatively straightforward, with clearly labeled controls and a traditional instrument cluster. The convertible top was power-operated and featured a glass rear window.
Exterior features included standard alloy wheels, a rear spoiler, and a body-colored front fascia. Optional exterior upgrades included chrome accents, upgraded wheels, and various paint colors. The trim level was generally considered a step up from the base V6 models, offering a more premium feel and a more powerful engine.
Chassis & Braking
The Mustang Convertible V 4.6 i utilized a traditional front suspension consisting of a strut design, while the rear suspension employed a three-link trailing arm setup. This suspension configuration provided a balance of ride comfort and handling performance. The chassis was reinforced to compensate for the loss of structural rigidity associated with the convertible body style. The braking system consisted of disc brakes on all four wheels, providing adequate stopping power for the vehicle’s weight and performance. Anti-lock brakes (ABS) were standard equipment.
The front stabilizer bar was designed to reduce body roll during cornering, enhancing handling stability. The rear stabilizer bar was typically smaller than the front, reflecting the vehicle’s rear-wheel-drive layout and weight distribution. Tire size was typically 235/55 R17, providing a good balance of grip and ride comfort.
Market Reception & Comparison
The 2005-2009 Mustang Convertible V 4.6 i was generally well-received by automotive critics and consumers alike. It was praised for its retro styling, powerful V8 engine, and comfortable driving experience. Compared to the V6 models, the 4.6L V8 offered a significant performance upgrade, making it a more appealing option for enthusiasts. Compared to the GT models, the automatic version offered a more relaxed and refined driving experience, albeit with slightly slower acceleration. Fuel economy was rated at 13.9 l/100 km (16.9 US mpg) in urban conditions and 9.4 l/100 km (25 US mpg) in extra-urban conditions.
Reliability was generally good, with the 4.6L V8 engine proving to be a durable and dependable powerplant. However, some owners reported issues with the automatic transmission, particularly with regard to shift quality and longevity. Overall, the Mustang Convertible V 4.6 i represented a compelling value proposition, offering a blend of performance, style, and affordability.
