We're going to break down everything you need to know about its specifications, so you can get a real feel for what makes this generation of the Civic Si so special. Whether you're a potential buyer, a current owner looking for details, or just a fan of Japanese performance cars, stick around because we've got the deets!

Engine and Performance: The Heartbeat of the Si

When we talk about the 2006 Honda Civic Si Coupe specs, the engine is where the magic truly begins. Under the hood of this bad boy is a 2.0-liter i-VTEC DOHC 16-valve inline 4-cylinder engine. Now, what does that actually mean for you? It means this engine is designed for both efficiency and spirited driving. Honda's VTEC (Variable Valve Timing and Lift Electronic Control) system is legendary for its ability to deliver power when you need it, especially at higher RPMs. This particular engine is tuned to produce a healthy 197 horsepower at 7800 rpm and 139 lb-ft of torque at 5800 rpm. That might not sound like supercar numbers these days, but for a compact car back in 2006, this was seriously impressive and gave the Civic Si a distinct performance edge. The engineers at Honda really focused on creating an engine that felt alive and responsive, making every drive, whether it's a commute or a spirited run on some twisty roads, an absolute blast. The powerband is quite broad, meaning you don't have to constantly rev the engine to the redline to feel the boost, although doing so is certainly rewarding! It's that kind of engaging driving experience that cemented the Civic Si's reputation as a driver's car. Plus, the i-VTEC technology ensures that this performance doesn't come at the complete expense of fuel economy, making it a practical choice for daily driving too. The sound of the engine, especially as it winds up, is also a major part of the Si's appeal – a throaty, sporty growl that lets everyone know something special is happening.

Transmission and Drivetrain: Shifting Gears with Precision

Part of what makes the 2006 Honda Civic Si Coupe specs so appealing to driving enthusiasts is its transmission. Honda decided to equip this sporty Civic exclusively with a 6-speed manual transmission. Yep, no automatic option here, guys! This was a deliberate choice to ensure the most engaging and connected driving experience possible. A 6-speed manual allows the driver to have complete control over gear selection, maximizing the engine's power delivery and allowing for precise shifts. The gearbox itself is known for its crisp, short throws and satisfying mechanical feel. It makes heel-toe downshifting a joy and allows you to really extract the most performance out of that 2.0-liter i-VTEC engine. The clutch is also well-weighted, providing good feedback without being overly heavy for daily commuting. This commitment to a manual transmission really underscores the Si's performance-oriented nature. It’s a car that encourages you to drive it, to interact with the machine, rather than just being a passive passenger. The drivetrain is front-wheel drive (FWD), which is typical for the Civic lineup. However, Honda's engineering team did a fantastic job of tuning the suspension and chassis to manage the power effectively and minimize torque steer, ensuring that the power gets to the road efficiently and predictably. This FWD setup, combined with the sporty suspension and the precise manual gearbox, makes the Civic Si incredibly nimble and fun to drive, especially on winding roads or during spirited acceleration. It's a setup that proves you don't need all-wheel drive to have a thrilling performance car.

Exterior Styling: Aggressive and Aerodynamic

Let's talk about how the 2006 Honda Civic Si Coupe specs look on the outside. The eighth-generation Civic, codenamed 'FA5' for the sedan and 'FG2' for the coupe, underwent a significant design overhaul compared to its predecessor. The Si Coupe, in particular, sports a more aggressive and futuristic styling. It features a distinctive front fascia with a unique grille and headlights, giving it a sharp, almost predatory look. The sloping roofline and the two-door coupe body style contribute to its sporty silhouette. You'll notice specific Si badges and aerodynamic enhancements, like a subtle rear spoiler and side skirts, that not only look cool but also contribute to downforce and stability at higher speeds. The coupe version is generally considered to be the more visually striking of the two Si variants available that year. It stands out from the regular Civic models with its more sculpted lines and bolder presence. The overall design language is characterized by sharp creases and a dynamic stance, reflecting its performance aspirations. The larger wheels, typically 17-inch alloys, further enhance its sporty appeal and fill out the wheel wells nicely. The dimensions are compact, making it maneuverable in urban environments while still offering enough interior space for its class. The glasshouse provides good visibility, crucial for sporty driving, and the overall proportions are well-balanced, giving it an athletic and purposeful appearance. It’s a design that, even years later, holds up well and continues to turn heads. It’s definitely not a car that blends into the background; it’s designed to be noticed.

Interior and Features: Driver-Focused Cockpit

Moving inside, the 2006 Honda Civic Si Coupe specs reveal an interior that prioritizes the driver. The cabin design is modern and features a unique two-tier dashboard that was quite futuristic for its time. The Si model gets sport-specific touches that set it apart. The seats are a major highlight – they are bolstered sport seats designed to hold you firmly in place during spirited driving, upholstered in a distinctive fabric with red stitching. The steering wheel is also a leather-wrapped unit, offering a comfortable and grippy feel. Red illumination for the gauges and interior lighting further enhances the sporty ambiance. You'll find the classic Honda ergonomics at play here, with all the controls falling easily to hand. The instrument cluster is clear and easy to read, with the tachometer prominently displayed. Despite its sporty nature, the Civic Si Coupe is still a practical car. It offers decent rear seating for a coupe and a reasonably sized trunk, making it usable for more than just weekend joyrides. Standard features on the Si model typically included power windows, power door locks, cruise control, air conditioning, and a premium audio system, often with an in-dash CD player and auxiliary input. The overall feel of the interior is one of quality and thoughtful design, with materials that feel durable and well-assembled. Honda is known for its build quality, and the Si is no exception. It strikes a great balance between a performance-focused cockpit and the everyday usability that makes a Civic a Civic. It’s a place where you feel connected to the car and ready for whatever the road throws at you.

Suspension and Handling: Agile and Engaging

When discussing the 2006 Honda Civic Si Coupe specs, the suspension and handling are crucial elements that define its driving dynamics. Honda engineers worked diligently to give the Si a chassis and suspension setup that complements its sporty engine and manual transmission. The car features a MacPherson strut front suspension and a multi-link rear suspension. This setup is tuned for a firmer ride compared to the standard Civic, providing a more direct connection to the road and reducing body roll during cornering. The springs are stiffer, and the dampers are tuned for better control, ensuring the car remains planted even during aggressive maneuvers. This is what gives the Si its renowned agility and responsiveness. The steering system is a power-assisted rack-and-pinion setup, which is known for its quick ratio and precise feedback. It allows you to place the car exactly where you want it on the road, making it feel incredibly nimble. The limited-slip differential (LSD) is another key component that significantly enhances handling, especially when exiting corners. The LSD helps to distribute torque more evenly between the front wheels, improving traction and reducing understeer, which is a common characteristic of front-wheel-drive performance cars. This allows you to put the power down more effectively out of turns, leading to faster lap times and a more confidence-inspiring driving experience. The brakes are also uprated for the Si model, typically featuring larger discs and calipers to provide stronger stopping power, essential for a car with this level of performance. All these elements combine to create a car that is not only fast in a straight line but also incredibly competent and fun to drive on a winding road. It’s a balanced package that rewards skilled driving.

Dimensions and Weight: Compact and Nimble

Understanding the 2006 Honda Civic Si Coupe specs also involves looking at its physical dimensions and weight. This compact sports coupe measures approximately 175.4 inches in length, 68.9 inches in width, and 55.0 inches in height. The wheelbase is around 104.3 inches. These dimensions contribute to its agile handling characteristics and make it easy to maneuver in tight spaces, such as city streets or parking lots. The coupe body style, as opposed to the sedan, often results in slightly different dimensions and a sportier profile. The curb weight for the 2006 Civic Si Coupe typically hovers around 2,900 to 2,950 pounds. This relatively light weight, especially when compared to modern cars, is a significant factor in its spirited performance and nimble handling. A lighter car requires less energy to accelerate, brake, and change direction, making it feel more responsive and engaging. The front-engine, front-wheel-drive layout, combined with this modest weight, makes the Si a fantastic platform for both daily driving and performance applications. The balanced weight distribution, while favoring the front due to the FWD layout, is managed well by the suspension and chassis tuning. The compact exterior dimensions also mean it fits into smaller parking spots, adding to its practicality as a daily driver. Despite its compact exterior, the interior is cleverly packaged to maximize passenger and cargo space, demonstrating Honda's engineering prowess in making the most of available room. The overall footprint is sporty and approachable, making it an attractive option for those who want a car that feels dynamic without being overly large or cumbersome.
