Alright guys, let's dive deep into the 2006 Subaru Impreza WRX Sedan 4D. This car, man, it's a legend in its own right. When you think performance sedans, especially from the mid-2000s, the WRX always pops up. It’s got that rally heritage, that turbocharged punch, and a look that just screams business. For 2006, Subaru decided to give the Impreza WRX a pretty significant facelift, bringing it more in line with the wider Subaru family design language, but without losing that aggressive, boy-racer charm that enthusiasts love. The sedan version, specifically the 4-door model, offered a bit more practicality than its hatchback counterpart, making it a sweet spot for those who wanted serious performance but also needed to haul groceries or a couple of friends without looking like they were smuggling a surfboard. This generation, often referred to as the 'GD' chassis, has a cult following, and the 2006 model year represents a really interesting point in its evolution. It’s a car that, even today, can put a massive grin on your face, whether you're carving up some twisty roads or just cruising around town. We're going to break down what makes this car tick, what you should look for if you're considering buying one, and why it remains such a sought-after machine in the used car market. So, buckle up, and let’s get into the nitty-gritty of the 2006 Impreza WRX Sedan.

The Heartbeat: Engine and Performance

Now, let's talk about the real reason most of us are interested in the 2006 Subaru Impreza WRX Sedan 4D: the engine. Under the hood, you're looking at Subaru's iconic 2.5-liter turbocharged, horizontally-opposed four-cylinder engine. This bad boy, often codenamed EJ255 for this specific application, is what gives the WRX its distinctive rumble and its exhilarating power delivery. For 2006, Subaru cranked up the boost and refined the tuning, leading to a healthy output of around 230 horsepower and 235 lb-ft of torque. Now, I know what some of you might be thinking, 'That doesn't sound like a ton of power by today's standards.' And you're not wrong. But here's the thing about the WRX: it's not just about peak numbers. It's about how that power is delivered. The turbocharger spools up with a satisfying whomp, providing a strong mid-range punch that really shoves you back in your seat. The boxer engine layout also contributes to a lower center of gravity, which, combined with Subaru's legendary Symmetrical All-Wheel Drive system, makes for incredible handling. That AWD system is a game-changer, especially in less-than-ideal weather conditions. It distributes power front-to-rear and side-to-side, giving you tenacious grip and confidence on pretty much any surface. The 2006 WRX typically came with a 5-speed manual transmission, which, while not the most refined gearbox in the world, is engaging and precise enough to make you feel connected to the car. The clutch is usually firm, and the shifter action, while a bit notchy, has a satisfying mechanical feel. This powertrain package, especially the AWD, is what cemented the WRX's reputation as a serious performance car that could punch well above its weight class and was equally at home on a track day as it was navigating snowy mountain passes.

Styling and Design: Aggression Meets Practicality

When Subaru redesigned the Impreza for the 2006 model year, they aimed for a more mature and cohesive look, and the 2006 Subaru Impreza WRX Sedan 4D definitely benefited from it. Gone were some of the quirkier, almost bug-eyed elements of previous generations. Instead, you got a sharper, more angular front end with a prominent grille and revised headlights that gave it a more menacing stare. The hood scoop, a signature WRX feature, remained, serving both an aesthetic purpose and functional duty to help cool the intercooler. It’s that scoop, along with the aggressive front bumper and side skirts, that immediately tells you this isn't your average grocery-getter. The sedan body style, while perhaps less 'rally-replica' than the hatchback, offered clean lines and a distinct profile. It gave the WRX a more understated, yet still potent, presence. Compared to the standard Impreza, the WRX treatment added subtle but effective touches. The wider fenders housed slightly wider wheels and tires, hinting at the car's performance capabilities. The rear of the sedan featured a clean trunk lid, often with an optional small spoiler, and distinctive taillights that rounded out the sporty look. Inside, the 2006 WRX sedan continued the theme of blending performance with daily usability. While the materials weren't exactly luxury-grade – it is a Subaru, after all – the layout was driver-focused. The bolstered sport seats were designed to keep you planted during spirited driving, and the overall ergonomics were pretty good for the time. The dashboard featured clear, legible gauges, including a prominent tachometer. For a performance car, the sedan body style meant you still had a usable trunk for everyday tasks, unlike some more specialized sports coupes. It was a clever compromise, offering a good balance between aggressive styling that hinted at its capabilities and the practicality needed for everyday life.

The Driving Experience: More Than Just Speed

So, how does the 2006 Subaru Impreza WRX Sedan 4D actually feel from behind the wheel? This is where the magic truly happens, guys. It’s not just about the horsepower figures; it's about the feel. The driving experience is raw, engaging, and incredibly confidence-inspiring, thanks to that Symmetrical All-Wheel Drive. Turn the key, and that boxer engine comes to life with a distinctive, slightly off-beat rumble that’s music to any gearhead's ears. Get it moving, and the steering feels direct and communicative, feeding you information about what the front wheels are doing. It’s not overly heavy, but it’s got enough heft to feel substantial. When you start to push it, the WRX really comes alive. The turbocharger spools up, and that wave of torque kicks in, propelling you forward with impressive urgency. The 5-speed manual transmission, while notchy, requires a firm hand and a precise foot, which really makes you feel involved in the driving process. Shifting gears becomes an event, a deliberate action that connects you to the machine. The suspension is firm – you're definitely going to feel the road, and there's not a lot of body roll when you throw it into a corner. This car grips. Seriously, the AWD system, combined with decent tires, allows you to carry remarkable speed through turns. You feel planted, secure, and in control, even if the road surface isn't perfect. It’s this combination of responsive acceleration, precise steering, and tenacious grip that makes the WRX so addictive. It's a car that encourages you to seek out winding roads, to push its limits (safely, of course!), and to enjoy the pure mechanical connection between you, the car, and the asphalt. It’s a car that’s as thrilling on a backroad blast as it is competent in daily driving, making it a true performance sedan icon.

Common Issues and What to Look For

If you're eyeing a 2006 Subaru Impreza WRX Sedan 4D, you're probably looking at a used car, and like any performance vehicle of this age, there are a few common pitfalls to be aware of. First off, the EJ255 engine, while potent, can be susceptible to head gasket issues, especially if it's been poorly maintained or driven hard without proper warm-ups. Look for signs of coolant loss, white smoke from the exhaust, or milky oil. Also, keep an eye on the turbocharger. These engines were known to develop ringland failure, particularly on modified cars running aggressive tunes or pushing too much boost. Listen for any knocking noises or excessive smoke. Regular maintenance is absolutely crucial for these cars. Check the service records diligently. Were oil changes done on time with the correct type of oil? Was the timing belt replaced at the recommended intervals? These are non-negotiable. Another thing to watch out for is clutch wear. The stock clutch can handle a decent amount of abuse, but if the previous owner was heavy-footed or used the car for frequent drag launches, it might be on its last legs. Test drive the car thoroughly; listen for grinding noises or a slipping clutch when you apply throttle in higher gears. Rust can also be an issue, especially on cars that have lived in areas with harsh winters where salt is used on the roads. Check the wheel wells, rocker panels, and the area around the rear bumper and taillights. The AWD system itself is generally robust, but check for any clunks or grinding noises from the differentials or driveshafts. Finally, these cars were popular for modifications. While some mods can be good, poorly executed tunes or excessive power upgrades can put a lot of stress on the drivetrain. Try to find a car that's either bone stock or has tasteful, well-documented modifications. A pre-purchase inspection by a Subaru specialist is highly recommended before you hand over your cash. It could save you a fortune in the long run.

Why the 2006 WRX Sedan Still Rocks
