The Ford Mustang Convertible V, as revised with a facelift in 2009, represented a continuation of the fifth-generation Mustang (S197) line, specifically tailored for open-air driving enthusiasts. Produced for the 2009 and 2010 model years, this variant featured a 4.0-liter V6 engine producing 210 horsepower. It occupied a middle ground within the Mustang Convertible lineup, positioned as a more affordable and fuel-efficient alternative to the higher-performance GT models with their V8 engines. The 2009 facelift brought subtle styling updates to the exterior, including revised headlights and grilles, and minor interior refinements.
The 4.0L V6 Mustang Convertible: Positioning and Overview
The 2009-2010 Mustang Convertible V with the 4.0L V6 engine was designed to appeal to buyers seeking the iconic Mustang experience without the higher price tag and fuel consumption associated with the V8-powered GT. It was marketed towards those who prioritized style, comfort, and a relatively economical driving experience. While not a performance leader, it offered a respectable level of power and handling for everyday driving and recreational cruising. This trim level was a key component of Ford’s strategy to broaden the Mustang’s appeal beyond its traditional performance-focused customer base.
Powertrain & Engine Architecture
At the heart of the Mustang Convertible V lay the Ford Cologne 4.0L V6 engine. This engine, designated as the engine code, had been a mainstay in the Mustang lineup since its introduction in 2005. It’s a 60-degree V-engine configuration, utilizing a single overhead camshaft (SOHC) design with two valves per cylinder. The engine employed multi-port fuel injection, delivering fuel directly into the intake ports. This system, while not as advanced as direct injection, provided reliable and efficient fuel delivery for the engine’s output. The engine’s bore and stroke measured 100.4 mm (3.95 in) and 84.4 mm (3.32 in) respectively, resulting in a total displacement of 4009 cm³ (244.64 cu. in). The compression ratio was set at 9.7:1.
The 2009-2010 models were exclusively offered with a 5-speed manual transmission. This transmission provided a relatively direct connection between the engine and the rear wheels, contributing to a more engaging driving experience. The transmission’s gear ratios were tuned to balance acceleration and fuel efficiency. The engine produced its peak power of 210 hp at 5300 rpm and 325 Nm (239.71 lb-ft) of torque at 3500 rpm. The engine oil capacity was 4.7 liters (4.97 US qt / 4.14 UK qt), and the cooling system held 11.8 liters (12.47 US qt / 10.38 UK qt).
Driving Characteristics
The 4.0L V6-powered Mustang Convertible offered a comfortable and predictable driving experience. Acceleration was adequate for everyday driving, with the 0-60 mph sprint taking approximately 7.8 seconds. While not as exhilarating as the V8-powered GT, the V6 provided sufficient power for merging onto highways and passing other vehicles. The 5-speed manual transmission allowed drivers to maintain control over the engine’s powerband, optimizing performance for different driving conditions. The engine’s torque curve was relatively flat, providing usable power across a wide range of engine speeds. However, the engine did lack the distinctive exhaust note and raw power of the V8 models. The convertible top mechanism, while convenient, did add some weight to the vehicle, slightly impacting handling and performance.
Equipment & Trim Levels
The Mustang Convertible V came standard with a range of features designed to enhance comfort and convenience. Standard equipment typically included air conditioning, power windows and locks, a CD player with an auxiliary input jack, and cloth upholstery. Safety features included anti-lock brakes (ABS) and front airbags. Optional extras included leather upholstery, a premium sound system, power driver’s seat, and alloy wheels. The interior design was relatively simple and functional, with a focus on providing a comfortable and user-friendly environment. The dashboard layout was straightforward, with easy-to-read gauges and controls. The convertible top was manually operated, adding a degree of driver involvement to the open-air experience.
Chassis & Braking
The Mustang Convertible V utilized a traditional rear-wheel-drive layout. The front suspension consisted of an independent McPherson strut design with a transverse stabilizer bar, providing a comfortable ride and predictable handling. The rear suspension employed a rigid axle setup with coil springs and a transverse stabilizer bar. This configuration, while not as sophisticated as independent rear suspension, offered a good balance of ride quality and handling characteristics. The braking system featured ventilated discs on all four wheels, with front discs measuring 293×30 mm and rear discs measuring 300×19 mm. The ABS system helped to maintain control during hard braking maneuvers. The steering system was a hydraulic rack and pinion setup, providing responsive and precise steering feel.
Market Reception & Comparison
The 2009-2010 Mustang Convertible V with the 4.0L V6 engine received generally positive reviews from automotive critics. It was praised for its affordability, stylish design, and comfortable ride. However, it was also criticized for its relatively modest performance compared to the V8-powered GT models. Fuel economy was a strong point, with EPA estimates of 18 mpg city and 26 mpg highway. In terms of reliability, the 4.0L V6 engine proved to be a durable and dependable powerplant. Compared to the Mustang GT, the V6 model offered significantly better fuel economy and a lower purchase price, making it an attractive option for budget-conscious buyers. However, the GT provided a more exhilarating driving experience and a more prestigious image.
