Infiniti G37 Convertible: Premium Drop-Top Performance

Introduction to the G37 Convertible Experience

The Infiniti G37 Convertible stands as a distinctive offering in the luxury convertible segment, blending sophisticated engineering with accessible pricing that appeals to enthusiasts seeking open-air driving without premium European price tags. This Japanese luxury sports car delivers a unique proposition: combining practical performance with everyday usability in a convertible platform that emphasizes comfort alongside driving engagement.

Powertrain and Performance Characteristics

At the heart of the G37 Convertible sits a 3.7-liter V6 engine producing 325 horsepower and 267 foot-pounds of torque. This powerplant provides responsive acceleration with a distinctive character that sets it apart from competitors. The engine exhibits deliberate engagement, requiring the driver to commit to acceleration rather than offering instantaneous thrust. Reviewers note that the V6 delivers a throaty, characterful exhaust note at higher RPMs, though this comes with slight coarseness and vibration that reflects the engine’s spirited nature.

Transmission options include both a six-speed manual and automatic variants, with the manual transmission garnering particular praise from performance-focused drivers. The manual offering provides an additional layer of engagement for those prioritizing driver involvement. When compared directly to the fixed-roof G37 coupe, the convertible experiences approximately a half-second penalty in 0-60 mph acceleration times, attributable to the additional weight of the hardtop structure and reinforcement components.

Structural Innovation: The Aluminum Hardtop Design

The G37 Convertible distinguishes itself through its power-folding aluminum hardtop roof, a feature that separates it from traditional fabric-top convertibles. This roof mechanism operates smoothly, requiring approximately 25 seconds to fully retract or extend. The hardtop engineering provides several practical advantages:

• Superior sound insulation compared to fabric convertible tops, reducing road and wind noise when the roof remains closed
• Enhanced structural rigidity that maintains the vehicle’s handling characteristics across driving conditions
• Improved security features, as the hardtop creates a more secure storage environment than soft-top alternatives
• Weather protection comparable to fixed-roof vehicles, allowing year-round usability in varied climates

The addition of the hardtop mechanism and reinforcement structure adds more than 400 pounds to the vehicle’s curb weight, impacting overall performance dynamics and contributing to a driving experience that prioritizes comfort and luxury over lightweight agility.

Handling and Driving Dynamics

The G37 Convertible showcases tuned suspension geometry that emphasizes responsive steering and engaging cornering dynamics. Reviewers consistently praise the steering feel as excellent and precise, with particularly quick response in the IPL variant. The steering exhibits a direct connection between driver input and vehicle response, distinguishing it from some competitors in the luxury convertible space.

The chassis tuning leans toward lively handling characteristics, with a slight tendency toward oversteer on aggressive driving inputs. This tuning philosophy reflects Infiniti’s performance DNA, creating a vehicle that rewards spirited driving on winding roads. While the G37 Convertible may not match the absolute grip levels of some European competitors, its chassis balance encourages active driver engagement and accessible performance thrills. Hydraulic power steering, retained across the model range, contributes to the refined steering feel and maintains a connection to traditional sports car character.

Interior Comfort and Luxury Appointments

Step inside the G37 Convertible, and occupants encounter a well-appointed cabin featuring supportive heated leather seating with substantial bolstering. The front seats provide extensive adjustability, accommodating drivers of varying sizes and preferences. Climate control operates through a dual-zone system, allowing separate temperature settings for driver and passenger. Premium audio systems, typically featuring Bose speakers with cleverly integrated headrest-mounted drivers, deliver impressive sound quality even with the top retracted.

Modern convenience features include Bluetooth connectivity with audio streaming, keyless entry and exit systems, HID headlights with integrated fog lights, and power-folding exterior mirrors. Navigation systems employ hard-drive-based GPS technology, providing reliable route guidance without dependency on cellular signals. The cabin design emphasizes quality materials and thoughtful ergonomics, creating an environment suitable for extended driving sessions.

However, rear seating represents a significant limitation, offering minimal practicality for adult passengers when front seats are occupied. The rear compartment functions best as occasional accommodation for children or brief trips, rather than serving as primary passenger seating.

Cargo Capacity and Practicality Considerations

Storage capacity presents interesting trade-offs inherent to the hardtop convertible design. With the roof in the retracted position, the trunk provides only approximately 2 cubic feet of storage space, substantially limiting luggage capacity during top-down driving. Conversely, with the roof in the raised position, total trunk volume expands to 10.3 cubic feet, providing reasonable accommodation for weekend getaway luggage or shopping excursions. This dynamic storage characteristic requires drivers to prioritize either cargo capacity or open-air motoring, rather than seamlessly combining both.

Performance Comparison and Market Positioning

The G37 Convertible occupies an interesting position within the luxury convertible market. It offers a certain lightness of control feel combined with engine character that distinguishes it from some European competitors, while maintaining accessibility through competitive pricing. When evaluated against vehicles like the Lexus IS C, the G37 Convertible provides a more powerful standard V6 engine alongside the manual transmission option, giving drivers choices that enhance engagement.

Model Variations and Trim Evolution

Throughout its production run, the G37 Convertible received incremental refinements without substantial structural changes. The 2012 model year, for instance, remained virtually unchanged from the 2011 version, maintaining the core formula that proved successful. Special editions like the IPL (Infiniti Performance Line) Convertible incorporated enhanced features including quicker-ratio steering geometry, providing an additional performance-oriented variant for enthusiasts. These variations allowed buyers to select configurations matching their priorities, whether emphasizing luxury amenities or performance enhancements.

Driving Experience and Character

The G37 Convertible emphasizes comfort-oriented performance rather than pure track-focused capability. The vehicle prioritizes smooth acceleration, refined cabin ambiance, and the sensory pleasure of open-air motoring over extreme cornering limits or raw acceleration metrics. This philosophy manifests in suspension tuning that smooths road imperfections while maintaining sufficient responsiveness for engaging road driving. The convertible delivers noticeable character differences compared to its coupe counterpart, with the additional weight and structural reinforcement creating a slightly more deliberate driving experience. Drivers consistently describe the car as “plenty fast” rather than extreme, with sufficient performance for spirited driving without demanding track-level skills.

Value Proposition in the Luxury Convertible Segment

The G37 Convertible maintains strong appeal through its combination of advanced technology, luxury appointments, and performance-oriented engineering at a price point that undercuts European luxury convertibles. This value positioning attracted buyers seeking sophisticated open-air driving without premium European pricing. The inclusion of quality amenities, responsive steering, and an engaging V6 engine created a compelling package for luxury-minded enthusiasts unwilling to compromise on driving engagement.
