For over 20 years, Honda has been using the Si designation to distinguish the high-performance Civic from its tamer counterparts.

In its latest iteration, the Civic Si features a 197-horsepower four-cylinder engine, close-ratio six-speed manual transmission and Helical limited-slip differential.

The sport suspension has MacPherson struts up front and a multi-link arrangement out back, plus firm spring rates, large stabilizer bars and responsive electric power steering.

These mechanicals make the Si a strong performer on curvy roads. It is often compared to the Volkswagen GTI, another small car with near the same horsepower and a sporty chassis, however, the Honda has been known to transition easier from corner to corner.

Unlike the GTI, the Civic Si is not available with an automatic transmission, only the six-speed manual.

High-performance summer tires are available in place of the all-season set-up, while the disc brakes are of the anti-lock variety and have Electronic Brake-force Distribution.

Despite all the go-fast items, the Civic Si still achieves respectable fuel economy. The EPA estimates 21 miles per gallon in the city and 29 on the highway. Premium fuel is required for the high-tech powerplant.

Honda makes sure the Si's appearance matches its sporting hardware, so standard styling cues include 17-inch alloy wheels, a chrome exhaust, tinted windows, rear wing spoiler, aluminum pedals and red back-lit gauges.

Other amenities that are standard include a 350-watt stereo with seven speakers and subwoofer, power sunroof, security system, air conditioning, power windows, power door locks, cruise control and leather steering wheel.

In fact, the only option for the Civic Si is a voice-activated navigation system, which also comes with XM satellite radio.

The Civic Si seats five, though those in the back may feel a bit cramped. Opt for the Si sedan for better back-seat accommodations.
