Audi S7's engine model is CEU, which is a 4.0-liter twin-turbocharged engine with a maximum power of 331 kilowatts and a maximum torque of 550 Newton-meters. The maximum power speed ranges from 5800 to 6401 revolutions per minute, while the maximum torque speed ranges from 1400 to 5700 revolutions per minute. It features direct fuel injection technology and uses an aluminum alloy cylinder head and block, paired with a 7-speed dual-clutch transmission. The front suspension of the Audi S7 employs a four-link independent suspension, and the rear suspension uses a trapezoidal multi-link independent suspension. It is equipped with a full-time four-wheel drive system and utilizes a crown gear center differential.

I remember studying the Audi S7 was quite fascinating. It typically comes with a 4.0-liter V8 twin-turbocharged engine, codenamed EA825, delivering around 450 horsepower and approximately 550 Nm of torque. The acceleration is exhilarating, achieving 0-100 km/h in just over 4 seconds. Technologically, it employs TFSI direct injection combined with a twin-turbo design, offering high efficiency and slightly better fuel economy. Paired with Audi's quattro all-wheel-drive system, it ensures no slipping even on wet roads. The engine produces a deep, powerful sound, making highway drives an absolute thrill. Maintenance-wise, regular oil changes and turbo inspections are crucial to prevent carbon buildup from affecting performance. Compared to other Audi models, the S7's V8 engine delivers a more sporty feel and has significant tuning potential, though fuel consumption is higher, averaging around 12L in city driving. I once drove a friend's S7, and the exhilarating push-back sensation remains unforgettable.

Driving the S7 is absolutely exhilarating. The engine is that 4.0-liter V8 twin-turbo monster, packing around 450 horsepower. Step on the gas, and the acceleration is lightning-fast with an intense kickback feeling. Hitting 200 km/h on the highway is a breeze. The exhaust note is deep and powerful, even more captivating than the BMW M series, and with quattro all-wheel drive, you won’t have to worry about slipping in corners. Fuel consumption is around 10-14L in the city, spiking during aggressive driving, but the overall power response is sharp. I’d recommend it to anyone who loves sports cars—this engine is finely balanced, offering both daily comfort and performance. Just remember regular oil changes and turbo inspections during maintenance. Compared to the standard Audi A7, the S7’s engine is far wilder, yet it’s still comfortable for long drives.

Having used the S7 for several years, the 4.0L V8 twin-turbo engine is the main powerhouse, with 450 horsepower delivering solid acceleration. Regular maintenance is key—I change the synthetic 5W-40 oil every six months. The turbos can be problematic, so it's important to check the pipes to prevent carbon buildup. Average fuel consumption is around 11-15L, which gets costly in city driving. The engine is fairly durable, but sensors occasionally fail and require professional repair. Daily driving is quiet and comfortable, while highway speeds bring strong bursts of power, and the quattro system ensures excellent grip. Remember to stick to regular maintenance to extend the engine's lifespan.
