Infiniti G37x: Complete Review And Buyer’s Guide

The Infiniti G37x represents a compelling entry into the premium coupe segment, combining Japanese engineering excellence with accessible luxury pricing. As an all-wheel-drive variant of Infiniti’s acclaimed G37 lineup, this model addresses a specific market niche—drivers seeking performance capability without sacrificing traction benefits during adverse weather. The G37x emerged as a response to strong customer demand, with European markets showing particular enthusiasm for the all-wheel-drive configuration, leading Infiniti to establish it as a dedicated model variant rather than merely an optional feature.

Engine Performance and Powertrain Configuration

At the heart of the G37x lies a robust 3.7-liter V6 engine, shared with Nissan’s performance-oriented 370Z platform. This naturally aspirated powerplant produces 330 horsepower and 270 pound-feet of torque, delivering performance metrics comparable to vehicles positioned at higher price points. The engine exhibits a distinctive character, emitting a gruff bark during cold starts that evolves into an almost V8-like metallic snarl under aggressive acceleration.

The transmission landscape varies by market and model year. All-wheel-drive G37x models utilize a seven-speed automatic transmission equipped with steering-wheel-mounted paddle shifters, enabling manual control when desired. In testing conditions, this automatic transmission demonstrated competent behavior during normal driving situations, though performance driving revealed some limitations. The transmission occasionally exhibits delayed response to downshift requests and can produce blurred shift quality under spirited driving. Rear-wheel-drive variants available in certain markets offer a six-speed manual option, providing enthusiasts with direct drivetrain engagement.

Acceleration figures reflect the engine’s substantial output. Zero to 60 mph capability ranges from 5.4 to 6.0 seconds depending on body style and specific testing conditions, with elevation and ambient temperature affecting performance. While not record-setting by contemporary standards, these figures demonstrate competitive positioning within the luxury coupe segment.

All-Wheel Drive Dynamics and Traction Characteristics

The all-wheel drive system distinguishes the G37x from its rear-wheel-drive siblings and represents one of its most compelling engineering achievements. Rather than compromising the car’s inherent sportiness, the AWD configuration maintains the sharp handling characteristics expected from Infiniti’s G-series platform. Engineers achieved this balance through meticulous system tuning, ensuring that understeer—a common trait in all-wheel-drive vehicles—remains remarkably moderate.

The all-wheel-drive system weight penalty of approximately 150 pounds has minimal detrimental effects on overall dynamics. While this additional mass extends the 70-to-0 mph braking distance by approximately 11 feet compared to rear-wheel-drive models, the enhanced launch traction more than compensates through improved acceleration capability. The system’s sophistication becomes apparent during aggressive driving, where the chassis responds to driver inputs with precision traditionally associated with rear-wheel-drive sports cars. This engineering accomplishment earned particular praise from professional reviewers, who noted that the AWD implementation feels transparent during spirited driving while providing genuine winter weather benefits.

Handling Characteristics and Suspension Dynamics

The G37x’s handling profile reflects Infiniti’s commitment to delivering engaging driving dynamics within a luxury context. The steering system strikes a careful balance, exhibiting slight on-center numbness at parking speeds while providing sharp, communicative feedback at higher velocities. This characteristic improves as drivers engage the chassis more aggressively, rewarding intentional input while filtering out minor road imperfections during relaxed cruising.

Body control demonstrates exceptional management throughout the driving envelope. The sport suspension geometry, combined with a limited-slip rear differential on performance-oriented trim levels, creates a chassis that responds immediately to driver commands. Lateral grip testing revealed skidpad performance of 0.83g on all-season rubber, respectable considering the compromise inherent in all-season tire selection. The suspension compliance remains supple even with performance-oriented spring and damping rates, ensuring that aggressive driving doesn’t translate to a punishing ride during extended highway cruising.

The suspension design philosophy prioritizes passenger comfort without surrendering responsiveness. Highway driving delivers pleasant refinement, with the chassis absorbing surface irregularities intelligently. The sport suspension tuning, despite its firmer calibration compared to standard setups, avoids the harshness that occasionally plagues vehicles with overly aggressive spring rates.

Climate control systems incorporate intelligent features such as automatic temperature regulation and zone-specific settings. Driver assistance technologies available on higher trim levels include intelligent cruise control systems that monitor preceding vehicle speeds and automatically adjust throttle response.

Seating arrangements balance support with long-distance comfort. Leather-accented surfaces appear throughout the cabin, with quality material selection elevating the perceived value proposition. The driving position accommodates various body types through comprehensive adjustment mechanisms, including power lumbar support on premium models.

Fuel Economy Considerations

Fuel consumption figures reflect the reality of operating a performance-oriented V6 engine within a premium coupe package. EPA estimates for G37x models register 18 mpg in city driving and 25 mpg during highway operation, with combined figures reaching 20 mpg. These numbers represent reasonable efficiency for naturally aspirated six-cylinder engines, though contemporary standards have evolved significantly. Real-world consumption depends substantially on driving methodology, with spirited driving noticeably reducing achieved mileage figures.
