How fast is a Honda CRX Si?
The speed of a Honda CRX Si in stock form is modest by modern standards, typically delivering 0–60 mph times in the high 9-second to about 10-second range with a top speed near 120 mph.
The US-market CRX Si from the EF chassis period (roughly 1988–1991) used a 1.6-liter inline-four engine producing about 108 horsepower, paired with a lightweight body and a 5-speed manual transmission. Real-world acceleration depends on condition, maintenance, tires, and altitude, so individual results can vary from the published figures.
Performance Snapshot for the US-Market EF Chassis (1988–1991)
Below is a core specification sheet for the US CRX Si to set baseline expectations for straight-line speed and everyday driving.
- Engine: 1.6-liter inline-four (D16A6), 16-valve DOHC, non-VTEC
- Power: about 108 horsepower (approximately 80 kW)
- Torque: roughly 100 lb-ft (135 Nm)
- Transmission: five-speed manual (standard); no factory automatic in Si trim
- Drive: front-wheel drive, front-engine
- 0–60 mph: commonly cited around 9.5–10.5 seconds
- Top speed: approximately 118–120 mph (190–193 km/h)
- Curb weight: about 2,350–2,500 lb (1,065–1,135 kg), varies with options
These figures come from Honda specification sheets and contemporary road tests. Real-world values can vary based on maintenance, weight from options, tire choice, and altitude.
Factors That Influence Speed and Acceleration
While the numbers above describe a stock baseline, several factors can move a CRX Si’s performance outside those ranges. Engine condition, clutch health, gear synchros, tire grip, aerodynamics from accessories, and even the weight of fuel and occupants all play a role. Lightening the car slightly (removing excess weight, quality tires) or improving engine efficiency (tune-ups, proper fueling) can shift 0–60 times a notch or two, while heavy wear or poor maintenance can slow acceleration.
In practice, owners who maintain the CRX Si well and run with lighter wheels or sport tires often observe 0–60 times toward the lower end of the 9–10 second window, whereas heavily worn engines or suboptimal tires tend toward the higher end or beyond.
Summary
The Honda CRX Si is a compact, lightweight sports coupe that achieves brisk, if not lightning-fast, straight-line speed for its era. In stock form, expect roughly 0–60 mph in the high 9s to around 10 seconds and a top speed near 120 mph, with real-world results shaped by maintenance, condition, and equipment.
