Every Honda Civic Si generation, measured
One row per generation. Watch the weight column — that is where most of the change happens for the Honda Civic Si, 600 lb of it since 1989, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.
| Generation | Length | Width | Height | Wheelbase | Curb weight |
|---|---|---|---|---|---|
| 1989–1991 | 156.3″ | 65.7″ | 52.4″ | 98.4″ | 2,161 lb |
| 1992–1993 | 160.2″ | 66.9″ | 53.1″ | 101.2″ | 2,313 lb |
| 2002–2004 | 165.7″ | 66.5″ | 56.7″ | 101.6″ | 2,760 lb |
From 1989 to today the Civic Si gained 9.4″ of length (6%) and 600 lb of weight (28%). A modern compact often outweighs the mid-size car of a generation before.

Will a Civic Si fit
The practical question behind every dimensions search, and for a 13.8-foot Honda Civic Si it has a straight answer. A single-car garage in the US is typically 20 feet deep and a street parking space about 18, so the Civic Si clears the garage by 5.2 ft. We allow a foot of clearance in both — nobody parks to the millimetre.
| Space | Typical size | This car | Verdict |
|---|---|---|---|
| Single garage | 20 ft deep | 13.8 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 13.8 ft | Fits comfortably |
| Standard parking bay width | 8.5 ft wide | 5.5 ft | Room to open doors both sides |
Against cars of the same length
Compared with 464 vehicles within ten inches of the same length — a fair proxy for «cars of this size», regardless of what the marketing calls them.
| Measure | This car | Typical car of this length | Difference |
|---|---|---|---|
| Width | 66.5″ | 68.1″ | -1.6″ |
| Wheelbase | 101.6″ | 99.2″ | +2.4″ |
| Curb weight | 2,760 lb | 2,840 lb | -80 lb |
A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. At 2,760 lb the Honda Civic Si is right on the class average, which generally shows up as fuel economy and stopping distance.

How we measure
Dimensions come from NHTSA vPIC and Transport Canada vehicle records — manufacturer-declared figures, held in metric and converted to inches and pounds for display, 8 measured model years for the Honda Civic Si between 1989 and 2004.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the Honda Civic Si fits into 3 rows instead of 8. Where a generation offered several body styles, the figures are the base measurements for that generation of the Honda Civic Si.
