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

The 2009 Infiniti G37 Sedan's curb weight ranges from 1624 kg to 1720 kg (3582 to 3792 pounds), depending on the configuration and options selected. The curb weight refers to the car's weight with all standard equipment, necessary operating consumables like oil and coolant, and a full tank of fuel but without passengers or cargo. The maximum weight, also known as the Gross Vehicle Weight Rating (GVWR), ranges between 2142 kg and 2198 kg (4723 to 4846 pounds). This maximum weight includes the vehicle's curb weight plus passengers, cargo, and any additional equipment. The weight profile supports the vehicle's performance-oriented nature while maintaining good fuel efficiency and handling dynamics.

The 2009 Infiniti G37 Sedan offers a luggage capacity of 382 liters (about 13.5 cubic feet), which is competitive for a sport-luxury mid-size sedan. This trunk space is sufficient to accommodate multiple suitcases or grocery bags, making it practical for daily use and road trips. When compared to competitors like the BMW 3 Series and Audi A4 from the same era, the G37’s trunk capacity is generally on par or slightly better, emphasizing Infiniti's balance between sporty design and utility. The rear seats typically fold down partially, further enhancing cargo flexibility. Thus, the G37 remains a good choice for buyers wanting a sport sedan without sacrificing cargo space.

Yes, the 2009 Infiniti G37 Sedan fits comfortably into most standard residential garages. With a length of 4755 mm (187.0 inches or about 15.4 feet), a width of 1773 mm (69.8 inches or roughly 5.8 feet), and a height between 1452 mm to 1469 mm (57.2 to 57.8 inches), it is well within the dimensions designed for typical single-car garage spaces. Standard garages generally offer widths around 2.4 to 3 meters (8 to 10 feet) and lengths between 5 to 6 meters (16.4 to 19.7 feet), so the G37 Sedan leaves ample clearance widthwise and in length. Its moderate height also ensures ease of entry without height concerns, including when accommodating garage doors or overhead storage.

The ground clearance of the 2009 Infiniti G37 Sedan ranges between 124 mm and 130 mm (approximately 4.9 to 5.1 inches). This relatively low ride height contributes to enhanced stability and a sportier driving experience, typical of performance sedans. On smooth pavement and highways, this low clearance helps reduce body roll and improve aerodynamic efficiency. However, it means the G37 is less suited for rough terrain or roads with large speed bumps, potholes, or heavy off-road use, as the undercarriage clearance is limited. Owners frequently use caution on steep driveways or uneven surfaces to avoid scraping. Overall, this clearance is appropriate for urban and suburban settings where road quality is consistent.

The 2009 Infiniti G37 Sedan comes with various rim sizes including 7.5J x 17, 7.5J x 18, and 8.5J x 18 inches. Correspondingly, it utilizes tire sizes ranging from 225/55 R17, 225/50 R18, to 245/45 R18 depending on trim level and packages. Larger 18-inch rims paired with lower profile tires (like 245/45 R18) typically offer better handling and cornering grip, providing a sportier drive feel with more road feedback. Smaller 17-inch rims with tire size 225/55 R17 usually enhance ride comfort and durability, especially on rough roads, due to taller tire sidewalls absorbing impacts better. Tire selection also influences braking performance and fuel efficiency. Buyers can select based on their preference between sporty dynamics or comfort.

Compared to its predecessor, the Infiniti G35 Sedan, the 2009 G37 Sedan (V36 generation) is slightly larger in several key dimensions. The G37 extends to a length of 4755 mm (187.0 inches) versus the G35’s approximate length of 4750 mm (186.9 inches), showing a subtle increase. The width also sees a slight bump to 1773 mm (69.8 inches) compared to the G35’s 1760-1770 mm range. Height remains relatively similar, with the G37 ranging from 1452 to 1469 mm (57.2 to 57.8 inches). Overall, the G37’s dimensional tweaks provided a roomier interior and enhanced road presence while maintaining the sporty and luxurious character of the G35. The incremental size growth supports added features and safety improvements that evolved from the previous generation.

When compared to similar sport-luxury sedans like the 3 Series from BMW and the Audi A4 from the same era, the 2009 Infiniti G37 Sedan holds its own in terms of overall size. The G37 has a length of 4755 mm (187.0 inches), which is slightly longer than the 2009 BMW 3 Series (E90) that measures around 4533 mm (178.5 inches), and the Audi A4 (B8) which is approximately 4656 mm (183.3 inches) long. Its width of 1773 mm (69.8 inches) is comparable, leaning slightly wider than the BMW 3 Series but similar to the A4. Height is also similar across these models. These size advantages in length and sometimes width can translate into a roomier cabin and bigger trunk, giving the Infiniti an edge in passenger comfort, while maintaining a sporty footprint that rivals its German competitors.

The 2009 Infiniti G37 Sedan weighs between 1624 kg and 1720 kg (3582 to 3792 pounds), depending on the vehicle’s option and trim. This weight provides a balanced foundation for the car, contributing to its solid road feel and dynamic handling characteristics. From a handling perspective, the weight supports strong stability during cornering and high-speed maneuvers without making the car feel heavy or cumbersome. However, this weight range is relatively average for a sport-luxury mid-size sedan and is designed with performance in mind. In terms of fuel efficiency, the G37's weight is a moderate factor; it doesn’t cause excessive fuel consumption but means the car won’t be as light or economical as compact sedans. Overall, the weight helps deliver the expected Infiniti driving experience with a combination of power, comfort, and agility.

The 2009 Infiniti G37 Sedan (V36) represents a refined evolution of Infiniti's mid-size sedan offering, known for its strong V6 engine performance, luxury appointments, and driver-focused dynamics.

The car features rear-wheel drive (with optional all-wheel drive in some markets), sport-tuned suspension providing agile handling, and a well-appointed interior featuring leather trim, advanced audio systems, and user-friendly controls. Safety features such as multiple airbags, stability control, and anti-lock brakes are standard. The G37 balances sporty performance and luxury comfort, making it a popular choice among enthusiasts and luxury car buyers alike.
