Infiniti G37S Coupe Complete Review: Power, Design, Value

The Infiniti G37S Coupe captures the essence of a modern grand tourer, offering a compelling mix of aggressive styling, potent V6 performance, and upscale comfort. Produced as part of Infiniti’s lineup in the late 2000s, this rear-wheel-drive two-door stands out for its ability to deliver thrilling drives without sacrificing daily practicality. With a 3.7-liter engine producing 316 horsepower, it accelerates from 0-62 mph in under 6 seconds while maintaining a composed demeanor on long journeys.

Striking Exterior Design That Demands Attention

The G37S Coupe’s bodywork exudes confidence through its elongated hood, flared fenders, and compact cabin positioned rearward. This classic coupe silhouette avoids excessive aerodynamic add-ons, relying instead on clean lines, a prominent grille, and distinctive L-shaped headlights to create a premium presence. Twin exhaust tips at the rear emphasize its sporty intent, and the overall proportions ensure it turns heads in urban settings or on highways alike.

Available in various colors, the coupe’s sheetmetal is both aerodynamic and structurally robust, contributing to its high crash safety ratings despite the added reinforcements needed for coupe-specific side-impact protection. At approximately 1719 kg, it’s heavier than some peers, but this mass is well-distributed thanks to the engine’s forward-central placement, aiding balance.

Luxurious and Driver-Focused Interior

Step inside, and the cabin welcomes with soft leather upholstery, ambient lighting, and supportive seats that hug occupants during spirited driving. The flagship S model elevates this further with power-adjustable memory seats featuring bolster controls, ensuring optimal comfort for both driver and front passenger. Materials feel upscale, though some plastic trim around controls shows cost-saving measures compared to pricier European rivals.

Key features include a color display for audio, climate, and optional navigation, an analog clock, and multiple USB ports—advanced for its era. Rear passengers in this 2+2 configuration have usable space for adults on shorter trips, aided by large windows and good visibility. The trunk, while narrow, accommodates weekend luggage effectively.

• Soft-touch leather seats with adjustable bolsters
• Ambient LED lighting for nighttime ambiance
• Bose audio system option with noise cancellation
• Intuitive infotainment with paddle-shift support

Potent 3.7-Liter V6 Powertrain

At the heart lies a naturally aspirated 3.7-liter V6 engine shared with the Nissan 370Z but detuned to 316 bhp and 360 Nm of torque for refined delivery. Paired with either a six-speed manual or automatic transmission with paddle shifters, it propels the coupe to 62 mph in 5.9 seconds and a limited top speed of 155 mph. Mid-range pull is strong, with a characteristic V6 rumble that grows vocal at high revs without becoming harsh in daily use.

Fuel economy averages around 10.4 l/100 km in mixed driving, higher in city conditions at 15.2 l/100 km, reflecting its performance focus. The limited-slip differential and sport-tuned suspension in the S variant enhance traction and composure.

Dynamic Handling and Ride Quality

On the road, the G37S shines with precise steering and balanced chassis dynamics. The front-central engine placement provides near-ideal weight distribution, making it predictable even at the limit. Sport suspension stiffens the ride compared to base models, reducing body roll while absorbing bumps adequately on smoother surfaces.

It’s more grand tourer than track weapon—smooth and urbane on motorways, yet responsive on twisty B-roads. Four-wheel steering (optional) further sharpens low-speed maneuverability and high-speed stability. Braking is confident with large discs, and the rear-drive layout delivers engaging tail-out fun when provoked.

Critics note the steering can feel slightly numb near the edge, and the suspension occasionally floats over rough patches, but overall, it’s immaculately behaved for a car of its size.

Advanced Technology and Safety Features

The G37S packs tech like active steering, DVD-based sat-nav, and a premium Bose system for immersive audio. Safety includes multiple airbags, stability control, and reinforced structure for high crash ratings. Paddle shifters and drive modes allow tailoring the experience from relaxed cruising to aggressive sprints.

Ownership Costs and Reliability

Priced competitively against BMW 3-Series or Audi A5, the G37S offers strong value with loaded spec sheets. Maintenance follows Nissan’s reliable VQ engine lineage, though fuel thirst and premium parts can add up. Resale holds decently for enthusiasts valuing its uniqueness.

Pros and Cons at a Glance

• Pros: Eye-catching design, powerful acceleration, comfortable seats, balanced handling
• Cons: Thirsty engine, limited rear space, some interior plastics
