All the goodness of the Honda Civic Si coupe has rubbed off onto 2007 Honda Civic Si Sedan. The same 197-horsepower iVTEC 2.0-liter engine screams to an 8,000-rpm redline, the same transmission shifts quickly through six gears, the same limited-slip differential delivers great punch exiting the corners and the same sport seats help you resist the G-forces.

The Civic Si sedan is 2 inches longer than the coupe and weighs 60 pounds more, but it has the same high-performance personality and even makes the same numbers at the test track. It just happens to have four doors. This is great news.

Acceleration:

With VSC off and a 4,000-rpm launch, the best 0-30 was the result of properly timing going to wide-open throttle. Too soon and the tires spin; too late and the engine falls out of the power. The shifter never balked or resisted an urgent throw. I got a little scratch on the 1-2 shift. I love the new exhaust note — still very much “Honda” but even meaner.

Braking:

Pedal firmness is spot-on for a sport sedan. I also tested our Civic Si coupe (with the all-season tires) today and I could really tell the difference in how the ABS system deals with the better summer tires. The summer tires are less gravely sounding and sure-footed under full ABS.

Handling:

With VSC off, understeer (eventually) limits the skid-pad performance, but it arrives gently and is easily recognized. In the slalom, the Civic Si sedan has a lot to say if your brain can process the info quick enough. Much of the discourse is regarding available grip and yaw rates, but there isn’t much info coming from the steering wheel itself; it’s mostly seat-of-the-pants stuff. That said, this thing likes to play rough. It can handle an aggressive toss and loves to power out of the exit with the limited-slip differential.
