INTRODUCTION

The Infiniti G37 Coupe, launched in 2007, marked a significant step forward for the brand, showcasing a more aggressive design language and a potent powertrain. It was built on the Nissan FM platform (front-mid engine, rear-wheel drive), also known as the V36 platform, shared with other Nissan and Infiniti models. The G37 replaced the G35 Coupe, offering increased power, refined handling, and a more luxurious interior. The 3.7-liter V6 engine was the centerpiece of this update, delivering a substantial performance boost over the outgoing 3.5-liter engine. The G37 Coupe aimed to appeal to buyers seeking a sporty and sophisticated coupe experience, offering a compelling alternative to European rivals.

Powertrain & Engine Architecture

The heart of the G37 Coupe 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 “VHR” designation stands for “Variable Valve Timing and lift with high revolution,” highlighting the engine’s advanced valvetrain technology. This system allows for precise control over valve timing and lift, optimizing performance across the rev range. The engine utilizes a multi-port fuel injection system, delivering fuel directly into the intake ports. The VQ37VHR produces 320 horsepower at 7000 rpm and 269 lb-ft of torque at 5200 rpm. The standard transmission for the G37 Coupe was a six-speed manual, but a five-speed automatic transmission was also available. The automatic transmission featured manual shift mode, allowing drivers to select gears for more control. The engine is longitudinally mounted, contributing to a balanced weight distribution and improved handling.

Driving Characteristics

The G37 Coupe with the 3.7-liter V6 and manual transmission delivers a genuinely engaging driving experience. Acceleration is brisk, with 0-60 mph times consistently in the 5.7-second range. The engine is responsive and eager to rev, providing a satisfying surge of power throughout the RPM band. The six-speed manual transmission offers precise shifts and a sporty feel. The automatic transmission, while smooth, doesn’t quite match the engagement of the manual. The rear-wheel-drive layout contributes to balanced handling and a playful character. The suspension is tuned for a balance between comfort and performance, providing a firm but not overly harsh ride. Compared to the G35 Coupe, the G37 offers noticeably more power and a more refined driving experience. The G37 also felt more planted and stable at higher speeds.

Equipment & Trim Levels

The G37 Coupe was available in several trim levels, including Base, Journey, and Premium. The Base model came standard with features such as leather upholstery, automatic climate control, a Bose audio system, and 18-inch alloy wheels. The Journey trim added features like a sunroof, heated front seats, and a power driver’s seat. The Premium trim included features such as navigation, a rearview camera, and upgraded leather upholstery. Optional extras included a limited-slip differential, adaptive dampers, and a performance exhaust system. Interior materials were generally high quality, with a focus on creating a luxurious and sporty atmosphere.

Chassis & Braking

The G37 Coupe utilizes an independent coil spring suspension in the front and an independent multi-link spring suspension with a stabilizer bar in the rear. This suspension setup provides a good balance between ride comfort and handling performance. The G37 Coupe is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) is standard. The steering is hydraulically assisted, offering a responsive and precise feel. The chassis is relatively stiff, contributing to improved handling and stability. The standard tire size is 225/50 R18, with larger 19-inch tires available on higher trim levels.

Market Reception & Comparison

The Infiniti G37 Coupe was generally well-received by automotive critics. Reviewers praised its powerful engine, engaging handling, and luxurious interior. However, some critics noted that the fuel economy was relatively poor for a coupe in its class. Compared to the G35 Coupe, the G37 offered a significant performance upgrade and a more refined driving experience. Against its European rivals, such as the BMW 3 Series Coupe and the Audi A5, the G37 offered a compelling value proposition, providing similar performance and features at a lower price point. The G37’s reliability was generally considered good, although some owners reported issues with the oil consumption of the VQ37VHR engine.

Legacy

The Infiniti G37 Coupe remains a popular choice in the used car market today. Its combination of performance, luxury, and style continues to appeal to buyers seeking a sporty and sophisticated coupe. The VQ37VHR engine is known for its durability and potential for modification. While some maintenance items, such as timing chain tensioners, may require attention as the car ages, the G37 Coupe is generally considered a reliable and rewarding vehicle to own. The G37 Coupe helped establish Infiniti as a serious contender in the luxury sports coupe segment, paving the way for future models like the Q60.
