The 2015 Infiniti Q50 3.7 represents a significant moment in the evolution of the luxury sedan, blending sporty performance with refined daily driving. This specific model year, powered by a naturally aspirated 3.7-liter V6 engine, offered a compelling mix of accessibility and power that defined a generation of the Q50 lineup. Understanding its capabilities requires looking beyond the raw number to how this powertrain interacts with the chassis and cabin.
Defining the 2015 Infiniti Q50 3.7
Positioned below the more potent twin-turbo variants, the 3.7 model served as the core luxury offering in the Q50 range for the 2015 model year. It was designed to attract buyers who prioritized luxury, technology, and confident handling over brute force. The 3.7-liter V6, codenamed VQ37VHR, was a well-regarded engine in the Nissan and Infiniti lineup long before it found its home in this sedan, known for its smoothness and reliability.
Powertrain Specifications and Output
Under the hood, the 2015 Infiniti Q50 3.7 generated a respectable 328 horsepower and 269 lb-ft of torque. This output was channeled to the rear wheels through a smooth seven-speed automatic transmission with paddle shifters. While these numbers might not sound staggering on paper compared to modern turbocharged engines, the real-world delivery was engaging and linear, providing ample passing power and maintaining a composed demeanor at highway speeds.
Driving Dynamics and Handling
Where the 2015 Q50 3.7 truly shone was in its handling dynamics. Infiniti's signature rear-wheel-drive platform provided a level of balance and feedback that felt premium and engaging. The steering was precise, and the chassis tuning struck an ideal balance between comfort and control, making it a joy to navigate through winding roads or busy city streets. This driving experience was a primary reason buyers overlooked the lower horsepower figure.
Refinement and Comfort
Inside, the cabin was a sanctuary of Japanese luxury, featuring high-quality materials, meticulous stitching, and a clean dashboard design. The seats offered excellent support and comfort for long drives, while the advanced infotainment system provided intuitive control over navigation, audio, and climate settings. The 3.7 engine complemented this serene environment with a muted growl rather than a harsh rumble, ensuring a peaceful interior.
Technology and Safety Features
For the 2015 model year, the Q50 was at the forefront of automotive technology, features that were often optional but came standard or were readily available on the 3.7 trim. This included the Around View® Monitor, which provided a 360-degree view of the vehicle for easier parking, and available advanced driver-assistance systems like Forward Emergency Braking and Lane Departure Prevention. These innovations underscored the model's commitment to safety and convenience.
