What does SI mean in Honda?
In the context of Honda vehicles, "SI" stands for "Sport Injection." This refers to a specific type of engine technology used in some Honda models that is designed to provide enhanced performance and efficiency.
Understanding the "SI" Designation in Honda
The "SI" designation in Honda vehicles indicates that the car is equipped with a Sport Injection engine. This engine technology was developed by Honda to deliver a balance of power, responsiveness, and fuel efficiency. The key features of Honda's SI engines include:
- Direct Fuel Injection: SI engines use a direct fuel injection system, which sprays fuel directly into the engine's cylinders rather than into the intake manifold. This allows for more precise fuel delivery and improved combustion, resulting in better power output and efficiency.
- High-Revving Design: SI engines are designed to operate at higher rpm ranges, enabling them to produce more power and torque than traditional port-injected engines.
- Variable Valve Timing: SI engines often incorporate variable valve timing technology, which can adjust the opening and closing of the engine's intake and exhaust valves to optimize performance and efficiency across a wide range of operating conditions.
Some of the Honda models that have been available with SI engines include the Civic Si, Accord Sport, and Pilot Sport. These models are typically marketed as the more performance-oriented variants within Honda's lineup, offering a sportier driving experience compared to their non-SI counterparts.
The Benefits of Honda's SI Technology
The key benefits of Honda's SI engine technology include:
- Increased Power and Torque: SI engines can produce more horsepower and torque than traditional port-injected engines, providing a more responsive and engaging driving experience.
- Improved Fuel Efficiency: The direct fuel injection and variable valve timing technologies used in SI engines can help improve fuel efficiency, allowing for better gas mileage compared to non-SI Honda models.
- Enhanced Driving Dynamics: The high-revving nature and performance-oriented tuning of SI engines can make Honda models with this technology feel more agile and fun to drive.
Overall, the "SI" designation in Honda vehicles indicates a sportier, more performance-focused version of the brand's engines, designed to deliver a more engaging and efficient driving experience.
What does SI mean on Honda?
sport injection
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. Enhanced with fuel injection, the Si's tiny engines had the extra power needed to set them apart.
Does Honda SI have VTEC?
The Feature: As the world's largest manufacturer of engines, Honda drew on many resources to create this exceptional powerplant. In addition to the intercooled turbo, this powerplant features VTEC, direct injection, Variable Timing Control (VTC) on both camshafts and a dual-exhaust system.
What is the fastest Honda?

Is Honda Type R faster than Si?
Is the Civic Si Faster Than the Type R? At the end of the day, speed is a key differentiator between the two vehicles. The Civic Si accelerates from zero to 60 mph in 6.9 seconds, but the Civic Type R is generally faster, reaching the same speed in just 5 seconds.
Does a Honda Si have a turbo?
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.
What does VTEC mean?
Variable Valve Timing & Lift Electronic Control System
Eventually the mechanism evolved into Honda's VTEC (Variable Valve Timing & Lift Electronic Control System) engine.
What is the point of Civic Si?
The 2025 Honda Civic Si sedan offers an exhilarating driving experience, known for its precise control and impressive performance. Powered by a turbocharged 1.5L 4-cylinder engine paired with a close-ratio 6-speed manual transmission, the Civic Si provides a perfect balance of power and agility.
What makes a Honda a SI?
SI stands for “Sport Injected”. It was introduced around the mid-1980s when standard Civic models were still carbureted. The SI models were the first Civics to have fuel injection. Today the SI models still contain upgraded engines, suspension, trim packages, etc when compared to the standard Civic models.
Is the Honda Si fast?
In our testing, the Honda Civic Si's 0–60 mph time was 6.6 seconds, 0.7 second quicker than the standard Civic hatchback we also tested with the six-speed manual transmission.
What does Si stand for for Honda?
Sport Injected
"Si" is a trim level offered by Honda on some of its models. It stands for "Sport Injected." Honda vehicles that carry the Si badge usually have more performance-oriented features than the standard models, such as a more powerful engine, sport-tuned suspension, and upgraded brakes.
