4 Answers
The displacement of the Audi S4 is 3.0 liters. Below is a detailed introduction to the Audi S4: 1. The Audi S4 is equipped with a 3.0-liter V6 turbocharged engine: This 3.0-liter V6 turbocharged engine delivers 354 horsepower and a maximum torque of 500 Nm, with the maximum torque available between 1,370 and 4,500 rpm and the maximum power output between 5,400 and 6,400 rpm. The engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. It is paired with an 8-speed automatic transmission (8AT). 2. The Audi S4 comes with a full-time all-wheel-drive system and uses a crown gear differential: Vehicles equipped with a full-time all-wheel-drive system have power delivered to all four wheels at all times, which enhances the mechanical grip of the wheels and improves the car's handling. 3. The Audi S4 is a sports sedan under the Audi brand: The dimensions of the Audi S4 are 4,749 mm in length, 1,842 mm in width, and 1,400 mm in height, with a wheelbase of 2,831 mm.
I've been driving the Audi S4 for quite a while now, and I feel its core highlight is that 3.0-liter turbocharged V6 engine, delivering 354 horsepower and 500 Nm of torque. Paired with the 8AT transmission, the acceleration is particularly direct. It's more than sufficient for daily tasks like picking up the kids, and when overtaking on the highway, it can surge forward in an instant. The 48V mild hybrid system makes start-stop incredibly smooth, so I never worry about fuel consumption in city traffic jams. The tuning community also loves this EA839 engine—just a simple Stage 1 tune can easily push it beyond 450 horsepower, and the stock pistons and connecting rods are strong enough, rarely needing reinforcement. Even though electric vehicles dominate the scene now, the thrill of this supercharged engine is still addictive, especially the low-frequency roar of the exhaust when you floor the throttle—it gets you pumped up right from the driver's seat.
As a performance car enthusiast, I've studied the engine details of the Audi S4. Its 3.0TFSI V6 turbocharged engine belongs to Volkswagen Group's golden displacement series, with a carefully designed bore-stroke ratio. The 84.5mm×89mm configuration ensures both ample low-end torque and high-RPM performance. Compared to the older supercharged version, the new turbo delivers peak torque at just 1700 RPM, working seamlessly with the Quattro all-wheel-drive system to maintain excellent traction even when exiting corners in rainy conditions. While the BMW M340i's B58 engine shows slightly better specs on paper, Audi's tuning delivers more composed performance, with less transmission jerk during daily commuting. For maintenance, be sure to use 0W-20 low-ash engine oil to prevent GPF clogging, and upgrading to high-performance spark plugs can significantly improve ignition efficiency.
Last week, I accompanied a friend to test drive the Audi S4, and the salesperson emphasized the 3.0T engine. Although the displacement is 1 liter larger than the A4, the fuel consumption is well controlled, averaging around 12 liters in urban conditions. What surprised me was that the trunk space wasn't affected by the four-wheel-drive system; a stroller and suitcases could easily fit. The turbo kicks in noticeably at 2,000 rpm, but it's not as abrupt as in AMG models. The lumbar support in the seats is particularly effective, making it comfortable even after three hours of continuous highway driving. The Germans clearly considered family needs in the design, as the rear seats don't feel cramped.
