1993 Infiniti J30 Dimensions, Size & Specs

The Infiniti J30 has a curb weight ranging between 1600 kg and 1601 kg (approximately 3527 to 3529 pounds). This weight is moderate for a midsize luxury sedan of its era, contributing to a stable and comfortable ride. The curb weight balances nicely with the vehicle's powertrain, allowing the car to offer smooth driving dynamics while maintaining relatively good fuel efficiency.

The Infiniti J30 offers a luggage capacity of 185 liters (about 6.5 cubic feet). While this is relatively modest compared to some of its contemporaries in the midsize luxury sedan segment, which often offer more generous trunk space, the J30 emphasizes style and passenger comfort more than cargo volume. Its compact trunk is best suited for everyday items, groceries, or small luggage rather than large suitcases or bulkier cargo.

The Infiniti J30 uses tires sized 215/60 R15 H. This tire size balances ride comfort and handling performance typical for early 1990s luxury sedans. The 15-inch tire diameter suits the car’s suspension setup, providing a smooth ride over various road surfaces and maintaining good traction, while the 215 mm width aids grip without negatively impacting fuel economy or ride quality.

Yes, the Infiniti J30 fits comfortably into a standard residential garage. With a length just under 4.86 meters (approximately 15.95 feet), width of 1.77 meters (5.8 feet), and height of about 1.39 meters (4.56 feet), the J30 is compact enough for typical single-car garages, which often have internal dimensions around 6 meters (20 feet) in length and 3 meters (10 feet) in width. Its manageable size makes parking and storage convenient for most homeowners.

The Infiniti J30 was a distinct model with no direct predecessor bearing the exact same nameplate in the Infiniti lineup, as it was introduced as a unique sedan in the early 1990s. However, compared to earlier Nissan luxury models such as the Nissan Maxima of similar years, the J30 was slightly more compact in width but comparable in length. Its design placed emphasis on a more personal luxury coupe-sedan blend, with dimensions tailored for elegant styling rather than maximum interior spaciousness, distinguishing it from broader, more traditional family sedans.

Compared to other 1990s midsize luxury sedans like the Lexus ES or Acura Legend, the Infiniti J30 is similar in overall length but tends to be slightly narrower and lower in height. This contributed to a sportier, more sleek appearance versus the often more spacious but bulkier profiles of competitors. While the J30 might offer slightly less interior and trunk space, its dimensions made it stand out as a stylish alternative that prioritized design and driving feel.

The Infiniti J30’s exterior dimensions suggest a focus on an intimate and comfortable passenger environment typical of personal luxury sedans. While it may not offer the expansive interior space seen in larger sedans, the relatively wide body and low height create a cozy, driver-focused cabin with supportive seating. Interior space is optimized more for front passenger comfort, with rear seating being adequate but not overly spacious. The elegant design and quality materials contribute to a luxury feel rather than prioritizing maximum passenger capacity.

With a height of around 1389-1390 mm (54.6 to 54.7 inches), the Infiniti J30 maintains a lower profile compared to many sedans of its time. This reduced height contributes positively to aerodynamics by lowering drag and wind resistance, which can improve fuel efficiency and high-speed stability. Visually, the lower stance enhances the sporty and elegant look, setting the J30 apart from taller, more traditional luxury sedans. This design choice supports both performance and aesthetic goals.

The luggage capacity of the Infiniti J30 is 185 liters (6.5 cubic feet), which is modest for a midsize sedan. This limited trunk space can pose challenges for families needing to carry larger amounts of luggage or bulky items regularly. While the car excels in style, comfort, and luxury amenities, its smaller cargo area makes it more suitable as a personal luxury vehicle or for couples rather than for families requiring extensive storage. For family use, buyers might prefer models with larger trunk volumes.
