The Ford Mustang VI 3.7 V6 Automatic represents a pivotal moment in the evolution of an American icon. Launched for the 2015 model year as part of the S550 generation, this Mustang was the first designed from the outset as a global vehicle, expanding its reach beyond North American shores. The 3.7-liter V6 Automatic variant, produced from 2015 to 2017, offered an accessible entry point into Mustang ownership, blending performance, style, and usability for a wide range of drivers.
The S550 Mustang: A Global Transformation
The S550 generation marked a significant departure for the Mustang. Prior iterations, while beloved for their raw power and classic design, often lacked the refinement and handling characteristics to compete effectively in the global sports coupe market. The S550 addressed these shortcomings with a completely redesigned chassis, most notably the introduction of an independent rear suspension (IRS) across the entire lineup. This, coupled with a more aerodynamic and contemporary exterior design, transformed the Mustang into a more sophisticated and globally competitive vehicle. The 3.7 V6 Automatic Fastback embodied this evolution, delivering a potent package that honored the Mustang’s heritage while embracing modern engineering.
Engine & Performance: The Duratec 37
Powering the Ford Mustang VI 3.7 V6 Automatic is the Duratec 37 engine, a naturally aspirated 3.7-liter (3726 cm3 or 227.37 cu. in.) V6. This engine had a proven track record within the Ford Motor Company, having been utilized in various models before its application in the Mustang. In this configuration, it produced 304 horsepower at 6500 rpm, resulting in a power-per-liter output of 81.6 Hp/l. Torque peaked at 366 Nm (269.95 lb.-ft.) at 4000 rpm, providing ample power for both spirited driving and confident highway maneuvers.
The Duratec 37 features a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow and enhancing high-rev performance. A multi-port fuel injection system ensures precise fuel delivery, while a compression ratio of 10.5:1 contributes to optimal performance using regular unleaded gasoline. Power is transferred to the rear wheels via a smooth-shifting 6-speed automatic transmission, providing a traditional sports car driving experience. The combination of the engine and transmission delivers a balanced and engaging driving experience.
Despite its performance capabilities, the 3.7 V6 Automatic also offered respectable fuel economy. Combined fuel consumption was rated at 10.7 l/100 km (22 US mpg), with urban figures at 12.4 l/100 km (19 US mpg) and extra-urban at 8.4 l/100 km (28 US mpg). This balance of power and efficiency made it an attractive option for drivers seeking a daily-drivable sports coupe.
Design & Features: A Modern Fastback
The S550 Mustang’s design successfully blended classic Mustang cues with contemporary aesthetics. The Fastback body style of the Ford Mustang VI 3.7 V6 Automatic presented a powerful and athletic stance, characterized by its long hood, short deck, and distinctive “shark bite” front fascia. The vehicle’s dimensions – 188.31 inches in length, 75.39 inches in width (81.89 inches with mirrors folded), and 54.41 inches in height – gave it a substantial road presence. The 107.09-inch wheelbase contributed to both stability and interior space, while the aerodynamic drag coefficient of 0.32 enhanced efficiency.
The introduction of the independent rear suspension was a key feature of the S550 generation, significantly improving ride quality and handling compared to previous solid-axle Mustangs. Electric power steering offered customizable feedback settings, allowing drivers to tailor the steering feel to their preferences. Ventilated disc brakes on all four wheels, coupled with an Anti-lock Braking System (ABS), provided enhanced safety and control. The vehicle rode on 235/55 R17 tires mounted on 17-inch alloy wheels, striking a balance between grip and ride comfort.
The interior of the Mustang VI featured a driver-focused cockpit with improved materials and ergonomics. While the V6 model was typically a more accessible trim level, it still offered a comfortable and engaging environment for four occupants, although the rear seats were best suited for smaller passengers or shorter trips.
