The Si model adds features such as a power sunroof/moonroof, tachometer, dual manual side mirrors, an upgraded interior, color-matched bumpers, dash clock, larger exhaust, front and rear anti-roll bars and 14-inch steel wheels with covers mounted with 185/60/R14 tires.

Under the hood of the Civic Si is a turbocharged 1.5-liter four-cylinder that makes 200 horsepower and 192 pound-feet of torque. That power is sent to the front wheels through a six-speed manual transmission and a standard limited-slip differential; an automatic option isn't currently offered.

Affordable performance at its finest. The Takeaway: Living in the shadow of the Type R, the Civic Si - short for “Sport Injected” - has long been for enthusiasts who want a fast Honda but can't afford the top-of-the-line model. However, for 2022, it doesn't feel like you're making a compromise by opting for the Si.

What's special about the Civic Si? Pop the hood of the Civic Si and you'll find a turbocharged 1.5-liter four-cylinder engine. It shares this engine with other turbocharged 2022 Civics, but the Si gets more power - 200 horsepower, to be precise, which is 20 hp more than the others.

It's relatively cheap at $27,300, $28,710 with everything. If you can find one. They are rare at the moment.

The 11th gen Si is also not a sports car. Sport compact sure, but that's always what the Civic Si has been.

In addition to the intercooled turbo, this powerplant features VTEC, direct injection, Variable Timing Control (VTC) on both camshafts and a dual-exhaust system.

Honda is attempting to justify the Si's higher base price by including more standard equipment including a premium audio system, a rev-matching feature for the transmission, and additional drive-mode customization options. Look for the new Civic Si to arrive at U.S. dealerships by the end of the year.

VTec engine is basically a variable valve engine. So the vehicle gives you the boost you need at higher rpms and good economy at lower rpms. A standard turbocharged engine is basically a boosted engine which gives you good power onces you've got good rpms running as in the case of any normal turbocharged engines.

sport injection For more than three decades, Honda models wearing little red Si badges have been among the most affordable and fun machines on American roads. Short for "sport injection" but really just a marketing term for fuel injection, the moniker first emerged in the mid-1980s when most Hondas were still carbureted.

Introduced for the 2017 model year, the Civic Si Sedan and Coupe were powered by a 205-horsepower version of the 1.5-liter Turbo (L15B7 High Output) paired exclusively with a manual transmission.

As the engine begins to spin more quickly, the center lobe takes over and the valves open sooner and closer later, which results in a sudden burst of speed and better performance. This change also causes the engine to have a sudden change in pitch - that's “VTEC kicking in.”

The genius behind VTEC is how it optimizes the resonance effect of fast-moving air. Engines produce power by compressing air and adding fuel and spark at opportune moments. Pumping large quantities of air through the intake manifold to the cylinders is no easy feat.

At our test track, the Civic Si managed a 6.8-second zero-to-60-mph time, 0.5 seconds quicker than a Civic hatchback we tested with the six-speed manual. Compared with the regular Civic, the Si has larger brake rotors and is available with a set of summer tires.

A short time later, VTEC was introduced on the 1991 Acura NSX, which developed 270 horsepower and 210 lb. -ft. of torque from its 3.0-liter V6 engine (C30A). Multiple variations of VTEC have been created over the decades to improve horsepower and torque while lowering emissions and increasing fuel efficiency.
