How much does a 1991 Honda CRX SI weigh?
The curb weight is typically around 2,050–2,150 pounds (about 930–975 kilograms).
In 1991, the Honda CRX Si stood as the sportier variant of Honda's compact CRX lineup, and its weight varied slightly by equipment and options. This article lays out the commonly cited figures, what those numbers mean, and how the weight compared with related trims from the era.
Curb weight: what it measures
Curb weight refers to the car's mass with standard equipment, fluids, and a typical fuel level, with no passengers or cargo. It is the baseline figure used to compare handling, performance, and efficiency across cars and trims.
Numbers cited for the 1991 CRX Si can differ by source due to measurement standards and options installed at the factory. The following figures are representative of US-market cars from that era.
- CRX Si (1991 US): approximately 2,050–2,150 lb (930–975 kg), depending on equipment such as air conditioning, radio, wheels, and other options.
- CRX HF (fuel-efficient variant): typically lighter, around 1,980–2,020 lb (900–918 kg).
In practice, the Si sits in the low-to-mid 2,000s pounds range, with lighter configurations dipping toward the upper 1,900s if minimal options are fitted.
How weight relates to performance and handling
Mass is just one factor in performance, but the CRX Si’s relatively light curb weight contributed to nimble handling, eager acceleration, and quick braking for a subcompact sport hatch of its era. Weight distribution and rigidity also played a role in its agile feel on winding roads.
Restoration and modification considerations
For restorations or modifications, expect weight to shift with aftermarket wheels, brakes, added insulation, or air conditioning upgrades. Each change can add or remove pounds, influencing handling and fuel economy.
Summary
The 1991 Honda CRX Si weighs roughly 2,050–2,150 pounds (about 930–975 kg) in curb weight, with exact figures depending on factory equipment and trim. This reflects Honda’s focus on a light, agile platform in the Si variant.
