The Infiniti Q60 S Limited 3.7 V6 Automatic, produced for the 2015 and 2016 model years, represented a compelling offering in the luxury sports coupe segment. Positioned as a premium trim within the first generation (Q60 I Coupe) of the redesigned model, it aimed to deliver a blend of performance, style, and technology. The Q60 replaced the G37 Coupe, and the S Limited variant was a short-lived, high-specification model intended to generate excitement around the new platform before the introduction of more mainstream trims. It was primarily marketed towards North American consumers seeking a sophisticated and powerful rear-wheel-drive coupe.

Powertrain & Engine Architecture
The heart of the Q60 S Limited is the VQ37VHR 3.7-liter V6 engine. This engine, a member of Nissan/Infiniti’s highly regarded VQ family, is naturally aspirated and known for its smooth power delivery and robust construction. The “VHR” designation signifies Variable Valve Timing and lift control, optimizing engine performance across the rev range. It utilizes multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The engine produces 335 horsepower at 7000 rpm and 270 lb-ft of torque at 5200 rpm. The engine is longitudinally mounted, driving the rear wheels. Paired with the VQ37VHR is a seven-speed automatic transmission, offering quick shifts and a relatively wide gear ratio spread. This transmission was designed to balance performance with fuel efficiency, although the Q60 was not primarily focused on maximizing MPG.
Driving Characteristics
The Q60 S Limited Automatic delivers a sporty, yet comfortable driving experience. The 3.7-liter V6 provides ample power for spirited acceleration, with a noticeable surge in the mid-range. While not as brutally fast as some turbocharged competitors, the Q60’s linear power delivery makes it predictable and enjoyable to drive. The seven-speed automatic transmission generally shifts smoothly, although it can occasionally feel hesitant during quick downshifts. Compared to a manual transmission equipped Q60, the automatic sacrifices some driver engagement but offers greater convenience, particularly in urban driving. The rear-wheel-drive configuration contributes to a balanced chassis and responsive handling, making the Q60 a capable performer on winding roads.
Equipment & Trim Levels
The S Limited trim was generously equipped. Standard features included leather upholstery, heated and ventilated front seats, a Bose premium audio system, a touchscreen infotainment system with navigation, and a suite of driver-assistance technologies such as lane departure warning and blind-spot monitoring. Exterior features included unique 19-inch alloy wheels, a sport-tuned suspension, and distinctive styling cues. Optional extras included a forward collision warning system and adaptive cruise control. The interior featured a driver-focused cockpit with aluminum trim and a generally upscale feel.
Chassis & Braking
The Q60 I Coupe utilizes a MacPherson strut front suspension and a multi-link rear suspension. The S Limited trim featured a slightly stiffer suspension tuning compared to lower trims, enhancing handling performance. Braking duties are handled by ventilated discs at all four corners, providing ample stopping power. Anti-lock brakes (ABS) and electronic brake-force distribution (EBD) are standard. The steering system is an electric power-assisted rack-and-pinion setup, offering precise and responsive steering feel.
Market Reception & Comparison
The Infiniti Q60 S Limited was generally well-received by automotive critics. Reviewers praised its powerful engine, comfortable ride, and stylish design. However, some criticized its fuel economy, which was typical for a naturally aspirated V6 engine of this size. Compared to competitors like the BMW 4 Series and Audi A5 Coupe, the Q60 offered a compelling value proposition, with a similar level of performance and features at a lower price point. The Q60’s rear-wheel-drive layout was also a selling point for enthusiasts, while some competitors offered all-wheel-drive as an option. The automatic transmission, while competent, was sometimes seen as less engaging than the available manual transmission.
Legacy
The VQ37VHR engine has proven to be a remarkably durable and reliable powerplant. With proper maintenance, these engines can easily exceed 150,000 miles. The seven-speed automatic transmission is also generally considered reliable, although regular fluid changes are essential. On the used car market, the Q60 S Limited holds its value reasonably well, particularly well-maintained examples with low mileage. It remains a popular choice for buyers seeking a stylish and powerful rear-wheel-drive coupe at an affordable price. While newer Q60 models have adopted turbocharged engines, the naturally aspirated V6 in the S Limited continues to be appreciated by enthusiasts for its smooth power delivery and distinctive sound.
