The curb weight of the Acura NSX I ranges between 1370 kg (3,020 lbs) and 1470 kg (3,241 lbs), depending on specific configurations and options. The maximum weight capacity, which accounts for passengers and cargo, is 1610 kg (3,549 lbs). This relatively lightweight profile for a mid-engine sports coupe enhances agility and performance.

The Acura NSX I offers a luggage capacity of 154 liters (about 5.4 cubic feet). While this is modest compared to regular sedans or SUVs, it provides sufficient space for small bags or daily essentials, which is typical for a high-performance sports coupe focused more on driving experience than cargo utility.

Yes, the Acura NSX I fits comfortably into a standard garage. With its length of 4425 mm (174.2 inches) and width slightly over 1.8 meters (about 71.3 inches), it is well within typical garage size standards, which are usually around 3 to 3.6 meters (10 to 12 feet) wide and over 5 meters (16 feet) long, allowing ample space for opening doors and maneuvering.

The Acura NSX I comes equipped with 17-inch rims paired with tire sizes of 245/40 R17, 215/40 R17, and 255/40 R17 depending on the position and variant. These wide, low-profile tires combined with appropriately sized rims enhance grip, cornering stability, and responsiveness, supporting the car’s sporty mid-engine layout.

The slight width variation from 1810 mm to 1811 mm (71.3 to 71.3 inches) is negligible and does not notably impact parking or road presence. This width makes the NSX I moderately wide for a coupe of its era, giving it a strong, stable stance on the road while still fitting into typical parking spaces with ease.

As the debut generation from 1990 with no direct predecessor under the Acura brand, the NSX I established a new benchmark by combining supercar performance with everyday usability. Compared to contemporaries like the Ferrari 348 or Porsche 911 of that era, the NSX I is slightly more compact in length and a bit lighter, with curb weights around 1370-1470 kg (3020-3241 lbs) versus heavier competitors, contributing to superior handling and efficiency.

At 1175 mm (46.3 inches) tall, the NSX I is a low-profile sports coupe offering a low center of gravity, which dramatically improves handling and stability during high-speed driving and cornering. However, this low height means that visibility—especially rearward—may be restricted compared to more conventional cars, requiring drivers to be mindful when parking and merging.

When compared to similar sports coupes of the early 1990s—such as the Porsche 911 (964 generation) and Ferrari 348—the Acura NSX I is competitive with its mid-engine layout, lightweight construction, and balanced dimensions. Its length of 4425 mm (174.2 inches) and weight between 1370 to 1470 kg (3020-3241 lbs) made it slightly more manageable in tight conditions and daily usability. Performance-wise, it offered reliable V6 powerplants and handling praised for precision, setting it apart as a practical yet exhilarating option.

The curb weight ranging from 1370 kg to 1470 kg (3020 to 3241 lbs) illustrates the Acura NSX I’s commitment to lightweight engineering, which is central to its design philosophy. By utilizing advanced materials like aluminum in the chassis and body panels, Honda (Acura) achieved a low mass that enhances acceleration, braking, and cornering while maintaining strong structural integrity and safety.
