Infiniti G Series Complete Review And Buying Guide

The Infiniti G series redefined luxury sports sedans with its blend of raw power, precise handling, and upscale interiors. Launched as a bold entry from Nissan’s premium brand, models like the G35 and G37 captured enthusiasts’ hearts by prioritizing driving dynamics over mere comfort. This article delves into the evolution, key features, performance metrics, ownership experience, and why these cars still hold appeal today.

Evolution of the Infiniti G Lineup

Infiniti entered the market in 1989 with modest expectations, producing mid-size coupes and sedans that struggled against established German rivals. Early models featured front-wheel-drive setups and lacked the excitement needed to compete. The tide turned in 2002 with the G35, which adopted rear-wheel-drive architecture, sharper styling, and a potent V6 engine, boosting sales significantly.

Building on this success, the G37 arrived in 2008, enlarging the engine to 3.7 liters for enhanced output while refining suspension and transmission options. Available in sedan, coupe, and convertible forms, with rear-wheel-drive, all-wheel-drive (AWD), and manual or automatic transmissions, it catered to diverse preferences. The G37x variants added AWD for better traction without sacrificing agility.

Powertrain and Performance Breakdown

At the heart of every Infiniti G is Nissan’s renowned VQ V6 engine. The G37’s 3.7-liter version delivers 328-330 horsepower and 270 lb-ft of torque, propelling the car from 0-60 mph in about 5.5 to 6 seconds depending on configuration. This naturally aspirated mill revs eagerly to 7,500 rpm, producing a thrilling exhaust note that rivals pricier competitors.

Transmission choices include a slick six-speed manual—praised for its precise shifts—or a seven-speed automatic with paddle shifters for everyday usability. The manual suits purists, while the automatic handles spirited drives adequately, though some note it lacks the razor-sharp response of dual-clutch rivals. AWD models like the G37x maintain balance, with the system enhancing cornering confidence even in wet conditions.

Performance shines in real-world scenarios: quarter-mile times hover around 13.9 seconds at 103 mph, matching contemporaries like the BMW 3-Series.

Handling and Ride Dynamics

Infiniti tuned the G series for sportiness, employing a control-arm front and multilink rear suspension. Sport packages stiffen springs, add larger anti-roll bars, and fit 19-inch wheels with high-performance tires, achieving 0.89g on the skidpad—impressive for the era. Steering provides excellent feedback, making canyon carving intuitive and fun.

While the ride can feel firm over rough roads, it’s composed and engaging, outperforming softer luxury sedans. AWD variants grip tenaciously, turning average drivers into confident handlers. Drawbacks include a harsher ride than BMWs and noise intrusion under hard acceleration.

• Key Handling Strengths: Precise steering, balanced chassis, limited-slip differential in Sport models.
• Potential Weaknesses: Stiff suspension on base models, tire noise on highways.

Interior Comfort and Practicality

Inside, the G offers a driver-focused cockpit with supportive leather seats, intuitive controls, and quality materials. Tech includes navigation, Bose audio, and Bluetooth—advanced for its time. Front space is generous, but rear legroom lags behind rivals, and the coupe’s sloping roofline cramps headroom. Trunk capacity is modest at 13.5 cubic feet in sedans, limiting utility for families.

Owners rave about the supportive seating and premium feel, with 79% of 2010 G owners awarding five stars for comfort. Build quality holds up well, contributing to positive long-term impressions.

Reliability and Ownership Costs

Infiniti G models earn high marks for durability, with many exceeding 150,000 miles on original components. The V6 is bulletproof, and maintenance is affordable compared to European alternatives. Common issues include timing chain guides in early VQs (addressed post-2008) and occasional transmission glitches in automatics. Fuel economy averages 18-25 mpg combined, a con for efficiency seekers.

Consumer data shows 93% recommendation rates, with performance and reliability as top praises. Insurance and parts remain reasonable, making used G37s bargains today—often under $15,000 for low-mileage examples.

Comparing G37 to Rivals

The G37 slots between entry-luxury like Acura TL and premium Germans. It undercuts BMW 3-Series on price while matching acceleration, but trails in refinement and resale. Against Audi A4, it offers superior power but less Quattro poise. Pros: value, fun factor; cons: fuel thirst, space constraints.

Best Years and Buying Advice

Target 2008-2013 G37s for refinements over G35. Avoid early 2003-2004 G35s due to engine woes. Inspect for service history, especially timing chains and leaks. AWD x models excel in snowy regions. Test drive manuals for ultimate engagement.
