The Infiniti G37 Convertible stands out as a premium drop-top vehicle that combines Japanese engineering precision with American-style luxury and European-inspired sportiness. Launched in the late 2000s, this model brought a retractable hardtop to the G-series lineup, offering drivers the versatility of a coupe during inclement weather and the freedom of a convertible under sunny skies. Powered by a robust 3.7-liter V6 engine, it delivers impressive acceleration and a refined driving experience, making it a compelling alternative to rivals like the BMW 3-Series Convertible or Lexus IS C.
Powerful Engine and Dynamic Drivetrain
At the heart of the Infiniti G37 Convertible lies its 3.7-liter V6 engine, producing 325 horsepower and 267 pound-feet of torque. This naturally aspirated powerplant provides smooth, linear power delivery, propelling the car from 0-60 mph in approximately 5.5 to 6 seconds, depending on the transmission choice. The engine’s responsiveness shines in mid-range acceleration, ideal for highway merging or spirited overtakes, though testers note a brief hesitation under hard throttle due to the convertible’s added weight.
Buyers had options between a six-speed manual gearbox for purists and a five-speed automatic with paddle shifters for everyday usability. The manual variant enhances driver engagement, with precise shifts and a mechanical feel that rewards enthusiastic driving. Rear-wheel drive is standard, contributing to the car’s playful handling characteristics, while sport-tuned models like the IPL variant add stiffer suspension and larger brakes for even sharper responses.
Innovative Retractable Hardtop Design
One of the G37 Convertible’s defining features is its power-retractable aluminum hardtop, which folds away in about 25 seconds at speeds up to 30 mph. This mechanism provides superior noise insulation and security compared to fabric roofs, maintaining coupe-like refinement with the top up. When deployed, the open cockpit invites fresh air and scenic views, transforming the car into a grand tourer.
Despite the engineering marvel, the hardtop impacts practicality. With the roof stowed, trunk space shrinks to a mere 2 cubic feet, limiting luggage to small bags. Keeping the top in place unlocks up to 10.3 cubic feet, sufficient for weekend getaways. The design also adds over 400 pounds to the coupe’s curb weight, slightly muting acceleration but enhancing structural rigidity for better high-speed stability.
Interior Comfort and Luxury Appointments
Step inside the G37 Convertible, and you’re greeted by a driver-focused cockpit boasting high-quality leather upholstery, heated and ventilated front seats with ample bolstering for support during aggressive cornering. The cabin layout prioritizes ergonomics, with controls falling readily to hand and a straightforward analog instrument cluster.
Technology abounds in premium trims: a hard-drive navigation system, Bose premium audio with headrest-integrated speakers for open-top listening, Bluetooth connectivity, and dual-zone climate control ensure connectivity and comfort. Keyless entry and start add convenience, while power-folding mirrors and HID headlights elevate the luxury quotient. However, rear seats are best suited for children or short trips, offering tight legroom and headroom for adults when fronts are adjusted back.
| Feature | Standard | Optional/Sport |
|---|---|---|
| Seating Material | Heated Leather | Ventilated Leather |
| Audio System | Bose 10-Speaker | With Headrest Speakers |
| Wheels | 18-inch | 19-inch Performance |
| Brakes | Standard | 4-Piston Front/2-Piston Rear |
Handling, Ride, and Safety Features
The G37 Convertible inherits the Nissan FM platform from the 370Z, delivering sharp steering and balanced chassis dynamics. Sport models feature a tuned suspension that minimizes body roll, allowing confident navigation of twisty roads. Braking is strong, with larger rotors in performance variants providing fade-resistant stopping power.
Ride quality strikes a balance between firmness for sporty feedback and compliance for daily commutes. Wind management with the top down is effective up to highway speeds, thanks to deployable wind deflectors. Safety includes six airbags, stability control, and optional radar-based blind-spot monitoring, contributing to strong crash-test ratings from federal agencies.
