The Infiniti G37 Convertible stands out as a compelling choice for drivers craving the perfect mix of high-end comfort, spirited performance, and the freedom of wind-in-your-hair motoring. Built on Nissan’s proven FM platform shared with the 370Z, this hardtop drop-top delivers a robust 3.7-liter V6 engine producing 325 horsepower and 267 lb-ft of torque, making it a force in the luxury convertible arena.
Powertrain and Performance Excellence
At the heart of the G37 Convertible lies a naturally aspirated V6 that propels the car from 0-60 mph in around 5.5 to 6 seconds, depending on transmission choice. Paired with either a slick 6-speed manual or a refined 7-speed automatic, the power delivery emphasizes smooth acceleration over razor-sharp responses, prioritizing grand touring comfort.
Drivers note the engine’s throaty growl builds to a crescendo at high RPMs, though some coarseness creeps in under hard acceleration. The manual gearbox, while slightly notchy, fosters a deeper connection to the road, ideal for enthusiasts who relish shifting gears themselves. Automatic versions shine in daily driving with paddle shifters for sporty overrides.
- Engine Specs: 3.7L V6, 325 hp @ 7,000 RPM, 267 lb-ft @ 5,200 RPM
- Transmission Options: 6-speed manual or 7-speed automatic with manual mode
- Top Speed: Electronically limited to 155 mph
- Fuel Economy: Approximately 17 mpg city / 28 mpg highway (EPA estimates)
Handling benefits from the rigid chassis reinforcements needed for the convertible structure, yet the added 400+ pounds over the coupe—totaling around 4,100-4,200 lbs—introduces noticeable body flex on uneven surfaces. Still, it corners competently with precise steering and upgraded Sport models featuring 19-inch wheels and summer tires for enhanced grip.
Innovative Retractable Hardtop Design
One of the G37’s standout features is its power-operated aluminum hardtop, which folds in about 25-30 seconds, stacking neatly behind the front seats in three sections. This design provides superior noise isolation and security compared to fabric roofs, maintaining coupe-like refinement with the top up.
With the roof deployed, trunk space shrinks dramatically to just 2 cubic feet—barely enough for a weekend bag—but expands to 10.3 cubic feet when stowed, offering practical storage for longer trips. The mechanism operates smoothly at speeds up to 30 mph, adding versatility for spontaneous top-down drives.
| Roof Position | Trunk Volume | Operation Time |
|---|---|---|
| Closed (Up) | 10.3 cu ft | N/A |
| Open (Down) | 2.0 cu ft | 25-30 seconds |
Interior headroom actually exceeds the fixed-roof coupe with sunroof, ensuring taller drivers enjoy a spacious cabin even under the closed lid.
Luxurious and Tech-Rich Cabin
Step inside, and the G37 Convertible envelops occupants in premium materials, including soft leather upholstery, aluminum accents with a textured finish, and well-bolstered seats offering heating and optional headrest speakers. Front seating provides ample adjustability and support for long hauls, though rear space is tight—best suited for children or short trips.
Technology abounds with standard features like dual-zone climate control, Bluetooth audio streaming, keyless entry, and a Bose premium sound system. Higher trims add hard-drive navigation, HID headlights, power-folding mirrors, and advanced brakes. The center stack is intuitive, blending physical controls with a clear display for effortless use.
- Spacious front legroom and headroom
- Supportive, heated leather seats
- Bose audio with innovative speaker placement
- Comprehensive safety suite: stability control, multiple airbags
Ride quality leans toward plush, absorbing bumps effectively while Sport variants firm up for keener dynamics. Wind buffeting with the top down is minimal thanks to effective deflectors.
Comparing to Key Rivals
In a crowded field, the G37 Convertible competes with the BMW 3-Series Convertible and Lexus IS C. It undercuts the BMW on price while matching or exceeding power, but trails in chassis precision and trunk usability when the top is down. Against the Lexus, the Infiniti edges ahead with more standard horsepower and manual option availability.
| Model | Horsepower | 0-60 mph | Base Price (Used Est.) |
|---|---|---|---|
| Infiniti G37 Convertible | 325 hp | ~5.7 sec | $15,000-$25,000 |
| BMW 3-Series Convertible | 300 hp | ~5.9 sec | $18,000-$30,000 |
| Lexus IS C | 306 hp | ~6.0 sec | $16,000-$28,000 |
The G37’s value proposition shines in the used market, where reliability from Nissan’s engineering keeps ownership costs low.
Ownership Experience and Reliability
Infiniti backs the G37 with one of the best warranties in its class, including 4 years/60,000 miles basic and 6 years/70,000 miles powertrain coverage—transferable to used buyers. Real-world reports praise its durability, with few major issues beyond routine maintenance. Fuel costs are reasonable for the performance, and parts availability remains strong due to Nissan shared components.
Potential drawbacks include limited rear access, minimal open-top storage, and a heavier feel impacting agility. Fuel economy dips in aggressive driving, but overall running costs are competitive.
Ideal Buyer Profile
This convertible suits couples or solo drivers prioritizing luxury cruises, weekend getaways, and occasional spirited runs over track-day prowess. It’s less ideal for families needing rear space or those demanding absolute lightness. In the pre-owned space, well-maintained examples offer premium thrills at bargain prices, especially Sport or IPL variants with enhanced tuning.
