The Heart of the Audi S3: Power and Potential
The Audi S3 has long been a benchmark for compact performance vehicles, blending everyday usability with a healthy dose of sporting prowess. At its core, the S3 is powered by Audi's renowned turbocharged two-litre four-cylinder engine. This powerplant is a masterclass in German engineering, delivering a potent combination of power, responsiveness, and refinement. However, for those seeking to push the boundaries of what this already capable machine can do, the aftermarket tuning scene offers a wealth of possibilities. One such example is the impressive transformation carried out by Manhart, turning the "humble" Audi S3 into the formidable Manhart S 400.
Audi's 2.0 TFSI Engine: A Proven Performer
The standard Audi S3 typically features a version of the 2.0-litre TFSI (Turbocharged Fuel Stratified Injection) engine. This engine has been a staple in the Volkswagen Group's performance line-up for many years, evolving and improving with each iteration. It's known for its strong torque delivery from low revs, a characteristic that makes the S3 feel brisk and engaging in daily driving. The turbocharging provides a significant boost in power, while the direct injection system ensures efficient fuel combustion. The inline-four configuration is a compact and well-balanced design, contributing to the S3's agile handling characteristics.
Key characteristics of the Audi S3's 2.0 TFSI engine include:
| Feature | Description |
|---|---|
| Displacement | 2.0 litres |
| Induction | Turbocharged |
| Fuel System | Direct Injection (TFSI) |
| Configuration | Inline-four cylinder |
| Typical Output (Stock) | Around 300-310 horsepower (varies by generation) |
| Torque Characteristics | Strong low-end and mid-range torque |
Manhart S 400: Unleashing More Power
The German performance tuning house, Manhart, has taken the excellent foundation of the Audi S3 and elevated it to a new level with their S 400 build. This isn't just a cosmetic enhancement; Manhart has delved deep into the mechanicals, significantly boosting the S3's performance credentials. The result is a car that not only looks aggressive but also delivers a thrilling driving experience, boasting an impressive 405 horsepower and a substantial 515 Nm of torque.
Engine Upgrades for the Manhart S 400
To achieve these remarkable figures, Manhart has implemented a series of targeted upgrades to the Audi S3's 2.0-litre turbocharged engine. These modifications are designed to improve airflow, enhance cooling, and optimise the engine's management system for increased output. The core of the power increase comes from a combination of:
- Wagner-made Intercooler: The intercooler plays a crucial role in performance tuning. It cools the compressed air from the turbocharger before it enters the engine. Cooler air is denser, meaning it contains more oxygen, which allows for more efficient combustion and ultimately, more power. A larger, more efficient intercooler, like the Wagner unit fitted by Manhart, is essential for handling the increased boost pressures and heat generated by a tuned engine.
- Carbon Air Intake: The air intake system is responsible for feeding air into the engine. A high-performance carbon fibre air intake, as used by Manhart, is designed to improve airflow by reducing restrictions and turbulence. Carbon fibre is lightweight and strong, and its smooth internal surfaces facilitate a more direct and unimpeded flow of air to the turbocharger. This improved breathing capability directly contributes to increased horsepower.
- ECU Remapping: Electronic Control Unit (ECU) remapping, also known as engine tuning or chipping, is perhaps the most significant modification for unlocking an engine's potential. Manhart's ECU remapping optimises various engine parameters, including fuel delivery, ignition timing, and turbocharger boost pressure. This ensures that the engine operates efficiently and safely at its higher performance level, taking full advantage of the upgraded hardware.
Beyond the Engine: A Complete Performance Package
Manhart's vision for the S 400 extends beyond just the engine bay. The German tuner understands that true performance enhancement requires a holistic approach. Therefore, alongside the significant engine upgrades, the S 400 also features:
- New Stainless Steel Exhaust System: A performance exhaust system is vital for releasing the gases produced by a more powerful engine. Manhart's stainless steel exhaust system is likely designed to be less restrictive than the stock unit, allowing exhaust gases to exit more freely. This not only contributes to improved performance but also enhances the exhaust note, giving the S 400 a more aggressive and sporting sound.
- Lowered Suspension: To complement the increased power and improve handling dynamics, the S 400 benefits from a lowered suspension setup. Lowering the vehicle's centre of gravity reduces body roll during cornering, allowing for faster and more precise turn-in. It also contributes to the car's aggressive stance.
- New Rims: The choice of wheels and tyres is critical for both aesthetics and performance. Manhart has fitted new rims to the S 400, likely chosen for their lightweight properties and their ability to accommodate larger, higher-performance brakes if specified.
- Sleek Charcoal Grey Finish with Red and Black Detailing: Visually, the Manhart S 400 is striking. The car is finished in a sophisticated charcoal grey, complemented by bold red and black detailing. This colour scheme is a signature of many performance tuning houses, conveying a sense of speed and dynamism.
