The Ford Mustang Convertible V, as revised with a facelift in 2009, represented a continuation of the fifth-generation Mustang (S197) line. Produced for the 2009 and 2010 model years, this variant featured a 4.0-liter V6 engine paired exclusively with a five-speed automatic transmission. It occupied the entry-level position within the Mustang Convertible range, offering a more accessible price point compared to the V8-powered GT models. This configuration aimed to provide open-air motoring enthusiasts with a balance of style, comfort, and reasonable fuel economy, though performance was naturally less emphasized than in its higher-tier siblings.
The 4.0L V6 Automatic: Positioning and Overview
The 2009-2010 Mustang Convertible V with the 4.0L V6 and automatic transmission was designed to broaden the Mustang’s appeal. Prior to the fifth generation, the Mustang had sometimes been perceived as solely a muscle car, catering to a limited audience. Ford aimed to change this with the S197 platform, offering a more modern and refined experience. The V6 models, particularly the automatic variants, were key to attracting buyers who prioritized comfort, style, and fuel efficiency over outright performance. This trim level was positioned below the Mustang GT, which boasted a significantly more powerful V8 engine and was geared towards enthusiasts seeking a more aggressive driving experience. The V6 automatic was also a step up from any previous base-model Mustang offerings, providing a more substantial engine and a more sophisticated transmission.
Powertrain & Engine Architecture
At the heart of the Mustang Convertible V was Ford’s 4.0-liter (4009 cc / 244.64 cu. in.) Cologne V6 engine. This engine, while sharing a lineage with earlier Ford V6 designs, had been significantly updated for the S197 platform. It featured a 9.7:1 compression ratio, a single overhead camshaft (SOHC) valvetrain with two valves per cylinder, and multi-port fuel injection. The engine produced 210 horsepower at 5300 rpm and 325 Nm (239.71 lb-ft) of torque at 3500 rpm. The engine’s block was constructed from cast iron, while the cylinder heads were made of aluminum, contributing to a reasonable weight balance. The engine code for this variant is generally identified as the Cologne engine, a designation reflecting its origins.
The engine was mated to a five-speed automatic transmission, a significant upgrade from the four-speed automatics found in earlier Mustang generations. This transmission was designed to provide smooth and responsive shifting, enhancing the overall driving experience. While not offering the driver control of a manual transmission, the five-speed automatic allowed for adequate acceleration and highway cruising capability. The transmission featured electronically controlled shifting and overdrive, contributing to improved fuel economy at higher speeds. The drivetrain configuration was rear-wheel drive, a traditional characteristic of the Mustang.
Driving Characteristics
The 2009-2010 Mustang Convertible V with the 4.0L V6 and automatic transmission delivered a comfortable and relaxed driving experience. Acceleration was adequate for everyday driving, with the engine providing sufficient power for merging onto highways and passing slower vehicles. However, it was noticeably slower than the V8-powered Mustang GT. The automatic transmission, while smooth, lacked the responsiveness and engagement of a manual gearbox. The gear ratios were tuned for fuel efficiency and comfort, rather than outright performance. The 0-60 mph time was typically in the 7.5-8.5 second range, depending on testing conditions and vehicle load. The power delivery was relatively linear, with peak torque available at a reasonably low 3500 rpm, making it suitable for everyday driving situations. Compared to the manual transmission V6, the automatic version typically resulted in slightly slower acceleration times.
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 a basic cloth interior. Safety features included anti-lock brakes (ABS) and front airbags. Optional extras included leather upholstery, a premium sound system, power-adjustable seats, and a color-matched hardtop for added security and weather protection. The interior dashboard configuration was relatively straightforward, with a focus on functionality and ease of use. The standard interior color options were typically dark gray or black. The convertible top was a manually operated soft top, though power-operated tops were available as an option.
Chassis & Braking
The Mustang Convertible V utilized an independent McPherson strut front suspension 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 was chosen to balance ride comfort with handling performance, while also keeping costs down. The front brakes consisted of ventilated discs measuring 293×30 mm, while the rear brakes were also ventilated discs, measuring 300×19 mm. The braking system was assisted by ABS, providing enhanced stopping power and control in emergency situations. The steering system was a hydraulic rack and pinion setup, offering responsive and precise steering feel. The standard tire size was 215/60 R17, though 235/50 R18 tires were available as an option on higher trim levels.
Market Reception & Comparison
The 2009-2010 Mustang Convertible V with the 4.0L V6 and automatic transmission received mixed reviews from automotive critics. While praised for its stylish design and comfortable ride, it was often criticized for its lack of performance compared to the V8-powered GT model. Fuel economy was generally considered acceptable, with EPA estimates of 14.7 l/100 km (16 US mpg) in the city and 9.8 l/100 km (24 US mpg) on the highway. Reliability was generally good, with the 4.0L V6 engine proving to be a durable and dependable powerplant. Compared to other trims in the Mustang lineup, the V6 automatic offered the best value for buyers who prioritized affordability and comfort over performance. It also provided a more fuel-efficient alternative to the V8-powered GT.
