The displacement of the S3 is 2.0 liters. Below are the relevant details: 1. The Audi S3 uses Volkswagen's third-generation EA888 engine, which delivers 290 horsepower and a maximum torque of 380 Nm. It can output maximum power at 5,400 to 6,500 rpm and maximum torque at 1,850 to 5,300 rpm. 2. This engine is equipped with hybrid injection technology and features an aluminum cylinder head and an iron cylinder block. The iron cylinder block can withstand higher temperatures and pressures, giving this engine significant tuning potential. It is paired with a 7-speed dual-clutch transmission, which offers higher transmission efficiency and extremely fast gear shifts. 3. The front suspension of the Audi S3 uses a MacPherson independent suspension, while the rear suspension employs a multi-link independent suspension. 4. The Audi S3 comes with a full-time all-wheel-drive system and a multi-plate clutch central differential. The all-wheel-drive system enhances the mechanical grip of the wheels, improving the car's handling and acceleration performance.

As someone who frequently hits the racetrack, I find the S3's displacement perfect for pursuing a sense of speed. It typically comes equipped with a 2.0-liter turbocharged engine, with a displacement of 1984cc, delivering around 310 horsepower. I've tested it on various road surfaces—this small-displacement design allows the car to unleash torque at low RPMs, accelerating from 0 to 100 km/h in just about 4.8 seconds, offering a strong push-back sensation without feeling bulky. Turbo technology also makes it excellent in fuel efficiency, averaging 7-8 liters per 100 km in city driving. Compared to high-displacement cars, the S3's 2.0-liter engine performs more nimbly in corners, especially when paired with the quattro all-wheel-drive system, making it both stable and exhilarating to drive. For long-term maintenance, pay attention to the turbo cooling system—regularly changing to high-performance engine oil can extend the engine's lifespan, ensuring no disappointment on track days.

The S3's 2.0-liter engine is quite worry-free for daily commuting. I've driven it to work, and the turbocharged engine doesn't jerk in city traffic, with power available on demand, making overtaking effortless. The smaller displacement also means better fuel economy; my real-world testing shows about 8.5 liters per 100 kilometers in mixed conditions, which is significantly more economical than some naturally aspirated cars. The cabin noise is well-controlled, making long drives less tiring, though the rear seat space is slightly cramped. For maintenance, the 2.0-liter engine requires high-quality oil, with synthetic oil changes recommended every 8,000 kilometers; brake pads wear out easily and need regular checks to avoid sudden issues. Overall, it's suitable for family use while still offering a sporty feel.

From a mechanical perspective, the 2.0-liter turbocharged engine standard on the S3 is meticulously designed, with a displacement of 1984cc and based on the EA888 engine series. The turbocharging enhances thermal efficiency. My analysis shows that this allows direct injection to reduce knocking, ensuring smooth power delivery. The small displacement paired with the DSG transmission provides quick response and makes it easier to pass emission tests during annual inspections. However, a downside is the potential for carbon buildup under prolonged high loads, requiring regular treatment with cleaning agents.

Recalling the evolution of the S3, its displacement has consistently remained at 2.0 liters. From driving the older models to the newer ones, while the engine size hasn't increased, the tuning has continuously been upgraded. Early models produced 260 horsepower, now exceeding 310, with torque also increasing, proving the great potential of small displacement. It still drives quietly and comfortably, making it suitable for long-distance travel. Combined with the Quattro all-wheel-drive system, it offers strong grip on wet or snowy roads. During maintenance, pay attention to sensor aging to prevent error faults.

From a practical perspective, the 2.0-liter engine of the S3 is sufficient and reliable for daily driving. I've encountered urban traffic congestion several times, and the engine delivers smooth power without vibration. Maintenance costs are manageable: oil change intervals are recommended to be shorter, and turbo components require frequent checks due to heat sensitivity; the smaller displacement also results in slightly lower insurance premiums. Compared to similar models, fuel consumption is easier to control, with noticeable savings on long-distance trips.
