Powertrain & Engine Architecture
The heart of the Q60 Journey 3.7 is the VQ37VHR 3.7-liter V6 engine. This engine is a member of Nissan/Infiniti’s highly regarded VQ engine family, known for its smooth operation and robust reliability. The “VHR” designation signifies Variable Valve Timing and lift control, enhancing both power and efficiency. The engine utilizes multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. It 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 smooth shifts and a balance between performance and fuel economy. This transmission features adaptive shift control, adjusting shift points based on driving conditions.
Driving Characteristics
The Q60 Journey 3.7 Automatic delivers a spirited driving experience. While not as aggressively tuned as some of its competitors, the 335 hp V6 provides ample power for both daily commuting and more enthusiastic driving. The seven-speed automatic transmission contributes to brisk acceleration, although it may not be as responsive as a dual-clutch transmission. Compared to the six-speed manual transmission available on some Q60 models, the automatic prioritizes comfort and ease of use over outright performance. The rear-wheel-drive configuration provides a balanced feel, and the suspension is tuned to offer a comfortable ride without sacrificing handling. The steering is precise and well-weighted, providing good feedback to the driver. The automatic transmission’s gear ratios are optimized for a blend of acceleration and highway cruising efficiency.
Equipment & Trim Levels
The Journey trim level of the Q60 I Coupe offered a well-rounded package of standard features. Interior appointments typically included leather upholstery, power-adjustable front seats, and a premium audio system. Standard technology features included a touchscreen infotainment system, Bluetooth connectivity, and a rearview camera. Optional extras available on the Journey trim included a navigation system, a sunroof, and advanced safety features such as lane departure warning and blind-spot monitoring. The interior design emphasized a sporty and luxurious aesthetic, with metallic accents and a driver-focused layout.
Chassis & Braking
The Q60 I Coupe utilizes a front independent multi-link suspension and a rear independent multi-link suspension. This setup provides a comfortable ride and good handling characteristics. The chassis is designed to be rigid, enhancing stability and responsiveness. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) is standard, enhancing safety during emergency braking situations. The steering system employs an electric power steering system, offering precise control and reduced weight.
Market Reception & Comparison
The Infiniti Q60 I Coupe Journey 3.7 V6 Automatic was generally well-received by automotive critics. Reviewers praised its powerful engine, comfortable ride, and stylish design. However, some critics noted that the interior materials were not quite as luxurious as those found in some of its European competitors. Compared to the base Q60 models with the 3.7-liter V6, the Journey trim offered a significant step up in terms of features and refinement. Compared to the higher-performance Q60 Red Sport 400, the Journey model offered a more accessible price point and a more balanced driving experience. Fuel economy was considered average for its class, with combined ratings around 22 mpg.
Legacy
The VQ37VHR engine has proven to be remarkably durable and reliable, and the Q60 Journey 3.7 Automatic remains a popular choice in the used car market. With proper maintenance, these engines can easily exceed 150,000 miles. Common maintenance items include regular oil changes, coolant flushes, and spark plug replacements. The Q60 I Coupe represents a compelling value proposition for buyers seeking a stylish and powerful rear-wheel-drive coupe. Its blend of performance, comfort, and reliability has ensured its continued appeal in the used car market.
