2009 Infiniti G37 Convertible (V36) Dimensions, Size & Specs

The curb weight of the 2009 Infiniti G37 Convertible is 1898 kg (4183 lbs). This weight reflects the solid build quality and the inclusion of convertible mechanisms, such as the retractable roof system. While heavier than its coupé counterpart, the G37 Convertible maintains a balanced chassis that supports spirited driving with responsive handling. The added weight does slightly affect fuel efficiency and acceleration compared to lighter vehicles, but it enhances stability and ride comfort. Infiniti's engineering ensures that this weight distribution delivers a driving experience that is both composed and enjoyable, especially important for a convertible where chassis rigidity must be reinforced.

The 2009 Infiniti G37 Convertible offers a luggage capacity of 366 liters (approximately 12.9 cubic feet). This is a respectable amount for a convertible, though naturally a bit less than you would find in a sedan due to space taken up by the retractable roof mechanism. The trunk can accommodate several medium-sized suitcases or bags, making it practical for weekend trips or daily errands. However, the storage volume does shrink when the roof is down, so users should consider this if they plan to carry luggage frequently while enjoying open-top driving. Overall, the G37 Convertible balances sporty design with useful cargo space adequately for its segment.

Yes, the Infiniti G37 Convertible typically fits comfortably into a standard garage. With a length of 4660 mm (183.5 inches), width of 1852 mm (72.9 inches), and height of 1400 mm (55.1 inches), it fits within the dimensions of a typical residential garage, which generally measures at least 6 meters (about 20 feet) in length and 3 meters (about 10 feet) in width. The low height of the convertible also ensures clearance under most garage doors and overhead storage setups. That said, owners should still measure their specific garage as variations exist between homes, especially with custom or smaller garages.

The Infiniti G37 Convertible comes equipped with rim sizes of 8.5J x 19 inches and 9.0J x 19 inches, paired with tire sizes of 225/45 R19 for the front and 245/40 R19 for the rear. These large 19-inch wheels with wider rear tires contribute significantly to the car's gripping power and sporty stance. The staggered setup—narrower fronts and wider rears—improves traction and cornering stability, especially in spirited driving conditions. The tires' profile balances comfort and precise handling, reducing sidewall flex for responsive steering feedback. Overall, the rim and tire configuration enhances the G37 Convertible's performance by combining aesthetic appeal with functional driving dynamics.

The 2009 Infiniti G37 Convertible (V36) marked a notable evolution over its predecessor, the Infiniti G35 Convertible. While maintaining a similar overall length, the G37 featured subtle refinements in its exterior proportions, with a slightly wider stance at 1852 mm (72.9 inches) that improved road presence and stability. The updated design was more aerodynamic and modern, with a lower height of 1400 mm (55.1 inches) contributing to a sleeker profile. Interior dimensions were refined for enhanced comfort, and the luggage capacity remained competitive at 366 liters (12.9 cubic feet). Mechanically, the G37 upgraded the powertrain for better performance and efficiency, while retaining the same elegant convertible practicality that fans appreciated in the predecessor.

When compared to similar luxury convertibles around its production years (2009-2015), such as the BMW 3 Series Convertible, Audi A5 Cabriolet, and Mercedes-Benz C-Class Cabriolet, the Infiniti G37 Convertible holds its own with competitive dimensions and features. Its length of 4660 mm (183.5 inches) is slightly longer than some rivals, providing a roomy cabin and trunk space of 366 liters (12.9 cubic feet), which is comparable. The width at 1852 mm (72.9 inches) ensures a stable ride, similar to that of German competitors. While the Infiniti features robust V6 power and sporty handling, it often stands out by offering a slightly more affordable option with luxury amenities and a comfortable ride. The large 19-inch wheels and staggered tires also emphasize sportiness that enthusiasts appreciate. Overall, it balances practicality, performance, and luxury effectively against its peers.

The Infiniti G37 Convertible is designed to provide a comfortable and enjoyable space for both driver and passenger. While explicit interior passenger dimensions for headroom and legroom vary slightly, the 1400 mm height (55.1 inches) supports sufficient headroom, even with the roof up. The cabin layout is ergonomically focused with supportive seats, premium materials, and a thoughtful design catering to both comfort and driving engagement. The rear seats are more limited, typical of the convertible segment, but adequate for occasional passengers or extra storage space. The convertible's retractable hardtop mechanism slightly reduces available headroom and cargo volume when stowed, but the G37 manages this compromise well by offering a spacious front seating area and well-appointed cabin features.

The Infiniti G37 Convertible measures 1400 mm (55.1 inches) in height and 1852 mm (72.9 inches) in width, dimensions that strike a careful balance between sporty design and practical usability. The relatively low height lowers the center of gravity, which enhances handling and vehicle stability, allowing the car to feel more planted during cornering or at higher speeds. The width provides a stable footprint that helps improve traction and road grip but remains manageable enough for parking in urban environments. The car’s moderate width generally fits standard parking spaces well, though its length of 4660 mm (183.5 inches) requires attention in tighter spots. These dimensions contribute to a confident driving experience both on highways and city streets.

The design of the 2009 Infiniti G37 Convertible efficiently combines exterior size with performance-oriented features. At 4660 mm (183.5 inches) long and 1852 mm (72.9 inches) wide, the car is large enough to provide a stable and comfortable ride, yet remains sufficiently compact to offer agility and maneuverability. Its sleek height of 1400 mm (55.1 inches) improves aerodynamics, reducing drag to enhance both performance and fuel efficiency. The convertible top mechanism is engineered to maintain chassis rigidity, ensuring handling precision despite the absence of a fixed roof. Large 19-inch wheels and a well-balanced curb weight of 1898 kg (4183 lbs) further enhance traction and acceleration. As a result, the G37 Convertible offers an engaging mix of sporty fun, open-air freedom, and practical daily usability.
