The Infiniti Q60 II Coupe 3.0t V6 (300 Hp) Automatic, launched in 2017, represents a significant iteration of Infiniti’s luxury sports coupe. Positioned as a mid-range offering within the Q60 lineup, it bridged the gap between the more accessible 2.0t models and the higher-performance Red Sport 400. Built on the platform shared with the Nissan Skyline, the Q60 aimed to deliver a blend of style, performance, and technology to the North American market, where it was primarily sold. This generation (introduced as a 2017 model) marked a substantial redesign from the previous G37 coupe, emphasizing a more refined and contemporary aesthetic.

Powertrain & Engine Architecture
The heart of the Q60 3.0t is the VR30DDTT 3.0-liter twin-turbocharged V6 engine. This engine is a significant departure from the naturally aspirated VQ37VHR found in the previous G37. The VR30DDTT utilizes direct injection and variable valve timing (VVT) on both intake and exhaust valves to optimize performance and efficiency. The twin-turbocharger setup, with electronically controlled wastegates, provides a broad torque curve and minimizes turbo lag. The engine produces 300 horsepower at 6400 rpm and 295 lb-ft of torque between 1600 and 5200 rpm. This power is delivered through a seven-speed automatic transmission with manual shift mode and adaptive shift control. The transmission is designed to provide smooth and responsive gear changes, catering to both spirited driving and comfortable cruising.
Driving Characteristics
The Q60 3.0t Automatic offers a balanced driving experience. While not as aggressively tuned as the Red Sport 400, it provides ample power for everyday driving and confident highway passing. The seven-speed automatic transmission is generally smooth, although some reviewers noted that it could occasionally feel hesitant during quick downshifts. The rear-wheel-drive configuration contributes to a sporty feel, and the available Dynamic Digital Suspension (DDS) further enhances handling by adjusting damper settings in real-time. Compared to the 2.0t models, the 3.0t offers a noticeable increase in acceleration and overall performance. However, the 2.0t models, particularly with the manual transmission, offered better fuel economy. The 3.0t’s power delivery is linear and predictable, making it easy to modulate throttle inputs.
Equipment & Trim Levels
The Q60 3.0t Automatic typically came standard with features such as leather upholstery, heated front seats, a dual-touchscreen infotainment system, a rearview camera, and a suite of driver-assistance technologies including automatic emergency braking and lane departure warning. Optional extras included a Bose premium audio system, navigation, adaptive cruise control, and the aforementioned Dynamic Digital Suspension. Trim levels beyond the base 3.0t often added features like upgraded interior trim, larger wheels, and more advanced safety systems. The interior design focused on a driver-centric layout with a focus on luxury and comfort.
Chassis & Braking
The Q60 3.0t utilizes a double wishbone front suspension and an independent multi-link rear suspension. This setup provides a good balance of ride comfort and handling precision. Brakes consist of ventilated discs all around, with larger front rotors (320mm) compared to the rear (307mm). Anti-lock braking system (ABS) and electronic brake-force distribution (EBD) are standard. The steering is electric power-assisted, providing a responsive and precise feel. The chassis is designed to be relatively lightweight, contributing to the car’s agility.
Market Reception & Comparison
The Infiniti Q60 3.0t was generally well-received by automotive critics. It was praised for its stylish design, comfortable interior, and strong performance. However, some reviewers criticized the infotainment system for its complexity and the lack of a traditional rotary controller. Compared to rivals like the BMW 4 Series and Audi A5 Coupe, the Q60 offered a competitive price point and a generous level of standard equipment. Fuel economy was considered average for its class, and reliability ratings were generally positive, although some owners reported minor issues with the infotainment system.
Legacy
The Infiniti Q60 3.0t V6 Automatic has established itself as a desirable used sports coupe. The VR30DDTT engine, while not without its complexities, has proven to be relatively reliable with proper maintenance. The availability of aftermarket performance parts has also contributed to its appeal among enthusiasts. As of today, well-maintained examples of the Q60 3.0t continue to hold their value, offering a compelling combination of style, performance, and luxury at a reasonable price point in the used car market. The Q60 represented a significant step forward for Infiniti in terms of design and technology, and it remains a popular choice for buyers seeking a sporty and refined coupe.
