The Infiniti Q60 Convertible, specifically the 3.7-liter V6 variant producing 320 horsepower and paired with a 7-speed automatic transmission, was a luxury sports convertible offered by Infiniti between 2013 and 2016. Positioned as the performance-oriented offering within the Q60 Convertible lineup, it represented a step up from potential future, lower-powered engine options that were never realized. It was a key model in Infiniti’s attempt to capture a segment of the premium convertible market, competing with vehicles like the BMW 4 Series Convertible and the Mercedes-Benz C-Class Cabriolet. The Q60 Convertible was based on the same platform as the Infiniti G37 Convertible, representing a significant refresh and rebranding effort for the model.

INTRODUCTION
The Infiniti Q60 Convertible 3.7 V6 Automatic, produced from 2013 to 2016, represented a significant evolution of the G37 Convertible. Infiniti aimed to elevate the model’s positioning within the luxury sports convertible segment, focusing on a blend of performance, style, and technology. The Q60 Convertible was built on the FM (Front-Midship) platform, a rear-wheel-drive architecture designed to optimize weight distribution and handling. This particular variant, with its 320-horsepower V6 engine and seven-speed automatic transmission, was positioned as the primary performance offering, appealing to buyers seeking a more engaging driving experience than a potential four-cylinder base model.
Powertrain & Engine Architecture
At the heart of the Q60 Convertible 3.7 is the VQ37VHR 3.7-liter V6 engine. This engine is a naturally aspirated, 24-valve DOHC powerplant known for its smooth power delivery and robust construction. The “VHR” designation stands for “High Revolution,” indicating the engine’s capability to rev freely. It utilizes a continuously variable valve timing control system (CVTCS) on both intake and exhaust valves, optimizing performance across the rev range. Fuel delivery is managed by a multi-port fuel injection system. The engine produces 320 horsepower at 7,000 rpm and 265 lb-ft of torque at 5,200 rpm. The engine is longitudinally mounted, contributing to the car’s balanced handling characteristics. The 7-speed automatic transmission, sourced from Jatco, features Adaptive Shift Control (ASC), which learns the driver’s habits and adjusts shift points accordingly. Manual shift mode is also available via steering wheel-mounted paddle shifters, offering a degree of driver control. The transmission is designed for smooth and responsive operation, complementing the engine’s power delivery.
Driving Characteristics
The Q60 Convertible 3.7 Automatic delivers a spirited driving experience. Acceleration from 0-60 mph takes approximately 6.1 seconds, making it competitive within its class. The 7-speed automatic transmission provides quick and precise shifts, although some reviewers noted that it could occasionally feel hesitant during downshifts. The rear-wheel-drive configuration contributes to a balanced feel, and the relatively short wheelbase enhances agility. Compared to a manual transmission-equipped Q60, the automatic version sacrifices some driver engagement but offers greater convenience, particularly in urban driving conditions. The engine’s torque curve is relatively flat, providing ample power for both everyday driving and spirited acceleration. The convertible top mechanism does add some weight to the vehicle, slightly impacting handling compared to the coupe version, but the overall driving experience remains enjoyable and engaging.
Equipment & Trim Levels
The Q60 Convertible 3.7 Automatic typically came well-equipped with standard features including leather upholstery, heated front seats, a power-adjustable driver’s seat, a premium audio system, and a touchscreen infotainment system. Available options included a navigation system, a rearview camera, and a Bose premium sound system. Exterior features included 19-inch alloy wheels, automatic headlights, and a power-operated convertible top. Interior trim options were relatively limited, with most models featuring a black or gray leather interior. The overall interior design was focused on providing a luxurious and comfortable environment, with a focus on high-quality materials and attention to detail.
Chassis & Braking
The Q60 Convertible utilizes a four-wheel independent suspension system, featuring double wishbones at all four corners. This setup provides a comfortable ride while maintaining good handling characteristics. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. The steering system is a rack-and-pinion setup with electric power assist, providing precise and responsive steering feel. The Q60 Convertible’s chassis is reinforced to compensate for the lack of a fixed roof, ensuring structural rigidity and minimizing body flex.
Market Reception & Comparison
The Infiniti Q60 Convertible 3.7 Automatic received generally positive reviews from automotive critics. It was praised for its powerful engine, comfortable ride, and stylish design. However, some reviewers noted that the interior quality didn’t quite match that of its European competitors. Fuel economy was also a point of criticism, with the Q60 Convertible achieving relatively low mpg figures compared to some of its rivals. Compared to the Q60’s siblings, such as the 3.7-liter coupe, the convertible offered a more open-air driving experience but at the expense of some structural rigidity and practicality. The automatic transmission was generally well-received, but some enthusiasts preferred the engagement of the available manual transmission.
Legacy
The Infiniti Q60 Convertible 3.7 Automatic has proven to be a relatively reliable vehicle in the used car market. The VQ37VHR engine is known for its durability, and the 7-speed automatic transmission has also demonstrated good long-term reliability. Common maintenance items include regular oil changes, brake pad replacements, and tire rotations. The Q60 Convertible remains a popular choice for buyers seeking a stylish and affordable luxury sports convertible. Its combination of performance, comfort, and features makes it a compelling alternative to more expensive European models. While it has been superseded by newer generations of the Q60, the 2013-2016 model continues to hold its own as a capable and enjoyable convertible.
