This relatively narrow width for a sedan enhances ease of parking and maneuvering in urban environments while maintaining stable road grip and comfortable cabin space. The compact width is an advantage in congested traffic and tight parking spots, making the G20 practical for city dwellers seeking luxury combined with convenience.

The Infiniti G20's height ranges between 1395 mm and 1400 mm, which is about 54.9 to 55.1 inches (approximately 4.58 feet). This modest height gives the car a sleek sedan profile, contributing to its aerodynamics and sporty appearance. The relatively low height also helps improve handling by lowering the center of gravity, providing a more engaging driving experience while preserving passenger comfort.

The curb weight of the Infiniti G20 sedan ranges from approximately 1306 kg to 1325 kg (2880 to 2920 pounds). This moderate weight for a compact luxury sedan results in a good balance of performance and fuel efficiency. A lighter curb weight generally translates to more agile handling, quicker acceleration, and improved fuel economy. The G20's weight is in line with its engine and chassis design, allowing it to deliver responsive driving dynamics while maintaining efficient fuel consumption typical for early 1990s luxury sedans.

The trunk capacity of the Infiniti G20 ranges between 380 liters and 470 liters, which converts to roughly 13.4 to 16.6 cubic feet. This amount of luggage space is considered generous for the compact luxury sedan segment of its time, providing ample room for daily errands, business trips, or light recreational use. The flexible trunk size allows for accommodating suitcases, shopping bags, or sports equipment with relative ease, making the G20 a practical choice for buyers who want luxury combined with functionality.

The Infiniti G20 from 1991 to 2000 commonly came fitted with rims sized either 14 or 15 inches in diameter. The corresponding tire sizes were 195/65 R14 H or 185/65 R15. These tire dimensions were chosen to balance ride comfort, handling precision, and road grip. The tire aspect ratios and widths also reflect the sedan's performance focus on maneuverability and safety. Choosing proper rim and tire sizes is essential for maintaining the designed driving characteristics and ensuring optimal braking and fuel efficiency.

Yes, the Infiniti G20 sedan comfortably fits into a standard garage. With a maximum length of approximately 4510 mm (177.6 inches or 14.8 feet) and width up to 1700 mm (66.9 inches or 5.6 feet), it is well within the dimensions of a typical single-car garage, which usually measures at least 5.5 to 6 meters (18 to 20 feet) in length and 2.5 to 3 meters (8 to 10 feet) in width. This makes parking and storing the vehicle hassle-free and accessible for most homeowners.

The Infiniti G20 was introduced in 1991, replacing the Nissan Primera-based Nissan NX or earlier Nissan Bluebird derivations in markets where Infiniti was present. Compared to these predecessors, the G20 offered a more refined and slightly sportier compact executive sedan size. The dimensions—length around 4450 to 4510 mm, width about 1695 to 1700 mm, and height near 1395 to 1400 mm—marked a competitive size scale for its segment, enhancing interior space and luggage capacity compared to earlier models. The G20 improved both driving dynamics and comfort, emphasizing a sport-luxury niche that was less pronounced in its predecessor lineups.

The Infiniti G20 from 1991 to 2000 was positioned against competitors such as the BMW 3 Series (E36), Audi 80/90, and the Mercedes-Benz C-Class of the same era. Dimensionally, the G20 was similar in length and width to these rivals, with lengths generally between 4450 mm and 4510 mm (175 to 178 inches) and widths of roughly 1695 to 1700 mm (about 67 inches). What set the G20 apart was its Japanese engineering focus on reliability, a sporty yet comfortable ride, and a well-appointed interior. While it did not have the same badge prestige as some European competitors, the G20 offered a compelling blend of performance, practicality, and value.

Throughout its production from 1991 to 2000, the Infiniti G20 typically featured a 2.0-liter inline-four engine, known for its smooth power delivery and efficiency. In the early years, it inherited the Nissan SR20DE, a well-regarded naturally aspirated engine producing around 140 to 150 horsepower depending on the market and model year. Key features included front-wheel drive, manual or automatic transmission options, and a suspension tuned for a sporty yet comfortable ride. The interior usually emphasized luxury with options like leather seats, premium sound systems, and upgraded trim, positioning the G20 as a reliable and stylish compact executive sedan.
