The Infiniti Q60 I Coupe IPL 3.7 V6, produced for the 2014 and 2015 model years, represented a performance-oriented variant within the first generation (CV35 chassis) of the Q60 coupe. Positioned as a step above the standard Q60 3.7, the IPL (Infiniti Performance Line) model aimed to bridge the gap between the mainstream luxury coupe and the higher-performance Q60 Red Sport 400 that would arrive later. It was Infiniti’s attempt to offer a more engaging driving experience without the significant price jump of a full-fledged performance model. The IPL trim was a limited-production run, adding exclusivity to the already stylish Q60 coupe.

Powertrain & Engine Architecture
The heart of the Q60 IPL is the VQ37VHR 3.7-liter V6 engine. This engine is a naturally aspirated powerplant, meaning it doesn’t rely on turbocharging or supercharging for increased power. The “HR” designation signifies “High Revolution,” indicating a focus on high-rpm performance. The VQ37VHR features a 60-degree V-angle, dual overhead camshafts (DOHC), and four valves per cylinder. It utilizes a multi-port fuel injection system for precise fuel delivery. The engine produces 353 horsepower at 7400 rpm and 275 lb-ft of torque at 5200 rpm. The IPL variant received specific engine tuning and a revised exhaust system to achieve these figures, representing a modest increase over the standard Q60 3.7’s output. The engine is longitudinally mounted, driving the rear wheels. The transmission is a 6-speed manual, offering drivers a more connected and engaging driving experience.
Driving Characteristics
The Q60 IPL with the 6-speed manual transmission delivers a noticeably more spirited driving experience than the standard Q60. While not a track-focused machine, the IPL’s increased power and responsive throttle contribute to quicker acceleration and more confident passing maneuvers. The manual gearbox allows for precise control over gear selection, enhancing driver involvement. The gear ratios are well-matched to the engine’s powerband, providing strong acceleration in each gear. Compared to the standard automatic Q60, the IPL feels more agile and responsive. However, it’s important to note that the IPL’s suspension tuning is relatively conservative, prioritizing ride comfort over outright handling prowess.
Equipment & Trim Levels
The Q60 IPL came standard with a number of features designed to enhance both performance and luxury. These included unique IPL-branded exterior styling cues, such as a front chin spoiler, side sills, and a rear diffuser. Inside, the IPL featured sport seats upholstered in Monaco Red leather with Alcantara inserts, a unique IPL steering wheel, and aluminum pedal accents. Standard equipment also included a Bose premium audio system, a touchscreen infotainment system, and automatic climate control. Optional extras included a navigation system, power-adjustable seats, and a sunroof. The IPL trim was positioned as a mid-range offering, slotting between the base Q60 and the more expensive Q60 Red Sport 400.
Chassis & Braking
The Q60 IPL utilizes a MacPherson strut front suspension and a multi-link rear suspension. The suspension tuning was slightly firmer than the standard Q60, providing improved body control and reduced roll during cornering. The IPL also featured larger diameter brakes with ventilated discs at all four corners, offering improved stopping power. The braking system is assisted by ABS (Anti-lock Braking System). The steering is a rack-and-pinion system with electric power steering, providing precise and responsive steering feel. The Q60 IPL rides on 19-inch alloy wheels wrapped in performance tires, contributing to improved grip and handling.
Market Reception & Comparison
The Infiniti Q60 IPL was generally well-received by automotive critics. Reviewers praised its stylish design, engaging driving experience, and comfortable interior. However, some critics noted that the IPL’s performance gains over the standard Q60 were relatively modest. Compared to other coupes in its class, such as the BMW 3 Series and Audi A5, the Q60 IPL offered a compelling value proposition, providing a good balance of performance, luxury, and features. Fuel economy was typical for a V6-powered coupe of its era, averaging around 19.9 US mpg in combined driving. Reliability was generally good, although some owners reported minor issues with the infotainment system.
Legacy
The Q60 IPL represents a unique chapter in Infiniti’s history. It was a relatively short-lived model, but it helped to establish the IPL sub-brand as a purveyor of performance-oriented luxury vehicles. The VQ37VHR engine, in particular, is known for its durability and reliability. Today, the Q60 IPL remains a desirable used car, appealing to enthusiasts who appreciate its stylish design, engaging driving experience, and relatively affordable price. While not as common as the standard Q60, the IPL’s limited production run and unique features make it a collectible model for some Infiniti fans. The powertrain, while not groundbreaking in terms of efficiency, has proven to be robust and capable of providing years of reliable service with proper maintenance.
