S4 engine model is 3.0T V6. Here are the extended details: 3.0T V6 engine performance: The 3.0T V6 turbocharged engine delivers a maximum power output of 260 kW/5400-6400 rpm and a peak torque of 500 Nm/1370-4500 rpm, featuring turbocharging and direct fuel injection technologies. Audi S4 overview: In terms of exterior design, the Audi S4 doesn't differ significantly from the standard A4L. It features large air inlets on both sides of the bumper with a honeycomb mesh structure and chrome trim, creating a more aggressive sporty atmosphere. The headlight design matches the standard A4, with LED daytime running lights outlining the angular and sharp headlight contours. For the interior, the Audi S4 is equipped with an 8.3-inch floating LCD screen with a clean design. The MMI system offers three operation modes: voice control, steering wheel button control, and MMI Touch control pad. The system includes GPS navigation, emergency call service, Bluetooth telephony, CarLife/CarPlay, and vehicle connectivity functions.

As a long-time enthusiast who has closely followed the series, I can confidently say that the Audi S4 has been consistently equipped with a 3.0-liter TFSI V6 turbocharged engine in recent years, specifically the EA839 model. This engine has been used in the all-new S4 since its generational update in 2017, delivering 354 horsepower, paired with an 8-speed Tiptronic transmission and quattro all-wheel drive, offering very agile acceleration response, achieving 0-100 km/h in approximately 4.7 seconds. I have personally test-driven it several times, and it delivers early low-end torque, making it suitable for daily commuting, while also performing well at high speeds. In terms of design, it features a single-turbo layout and direct injection technology, with fuel consumption kept within a reasonable range—around 10L/100km in the city. Maintenance-wise, it's important to regularly change the oil and check for turbo overheating. Overall, its reliability is good, being lighter and more efficient than the older V8. If you upgrade the exhaust system, you can enjoy a deeper exhaust note.

Having driven the S4 for two years, the most impressive aspect is undoubtedly the 3.0 TFSI V6 engine (model EA839) with its authentic German engineering. The exhilarating acceleration push-back feeling it delivers is phenomenal – it consistently takes the lead from traffic light starts and provides ample power for highway cruising, while maintaining acceptable fuel consumption at 9-11L/100km in urban areas. For maintenance, I change the engine oil every 8,000 kilometers, occasionally clean carbon deposits from the turbocharger, but haven’t encountered any major issues. This engine pairs seamlessly with the 8AT transmission in the S4, offering top-notch smoothness, and the quattro system ensures rock-solid grip during cornering. On weekend family trips, the power is more than sufficient, and noise levels remain pleasantly subdued. New owners should definitely try Sport mode for a more aggressive throttle response.

The engine models of the S4 have undergone significant changes across generations. The early B5 generation used a 2.7L V6 biturbo, while the B6 and B7 generations switched to a 4.2L V8 naturally aspirated engine, delivering powerful performance but with higher fuel consumption. By the B8 generation, it transitioned to a 3.0L V6 supercharged engine, and the current B9 generation has standardized on the 3.0L TFSI V6, codenamed EA839. This latest model is the most mainstream, featuring a more compact and efficient design, paired with an 8AT transmission for smooth driving. Compared to historical versions, it shows notable improvements in reliability and environmental performance, delivering 354 horsepower that fully meets daily or sporty needs, with significantly reduced maintenance costs.

When comparing vehicles in the same class, the 3.0-liter TFSI V6 engine in the S4, model EA839, is no less impressive, delivering 354 horsepower. It's similar to the BMW M340i's 3.0-liter inline-6 turbocharged engine, but the S4's V6 layout offers better balance, more abundant low-end torque, and smoother linear acceleration. The Mercedes C43 also uses a V6 with forced induction, with comparable power figures, but the S4's quattro system provides more precise steering. In real-world driving, this engine is agile and quiet in city conditions, with strong high-speed performance, achieving a 0-100 km/h acceleration in just over 4 seconds. The performance is stable, and it's recommended to adjust the driving modes to optimize responsiveness.

When it comes to the driving experience of the S4, the heart of it all lies in that 3.0-liter TFSI V6 engine, model EA839. Step on the gas, and the power comes on quick and smooth, with 500 Nm of torque that you can feel even at low revs, giving you confidence whether you're starting off in the city or overtaking on the highway. Paired with the transmission, gear shifts are seamless without any jerkiness, and the quattro drive ensures no slipping on wet roads. Personally, I prefer using Dynamic mode—it makes the engine response even quicker, and with a slight tweak to the exhaust note, it sounds even more thrilling. Maintenance-wise, the turbocharger needs regular upkeep, but this design has excellent heat dissipation, reducing the risk of overheating. Overall, the S4 strikes a perfect balance between comfort and excitement, making it ideal for drivers who seek both.
