The displacement of the Audi S7 is 3993 milliliters. Definition of displacement: Displacement, a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. The displacement of a car is an important parameter to measure a vehicle. Some domestic cars do not have the car model marked on the rear, but the displacement is usually indicated on the body or rear of the car. Displacement classification: The classification of car levels in China is determined by the size of the displacement. Mini cars have a displacement of 1.0 liters or less; compact cars have a displacement ranging from 1.0 to 1.6 liters; mid-size cars have a displacement ranging from 1.6 to 2.5 liters; executive cars have a displacement ranging from 2.5 to 4.0 liters; and luxury cars have a displacement greater than 4.0 liters.

I remember the Audi S7 usually comes with a 4.0-liter V8 twin-turbo engine, and driving it is absolutely exhilarating! It can accelerate from 0 to 100 km/h in just over four seconds, making overtaking on the road effortless. The engine sound is deep and powerful, unlike smaller-displacement cars that feel a bit lightweight. I drove an S7 once and felt the overall design was quite thoughtful—the trunk space is generous, easily fitting several suitcases, and the quattro all-wheel drive provides solid traction in rain or snow, eliminating worries about slipping. In terms of fuel consumption, it’s around 12 to 14 liters in the city and can drop to about 8 liters on the highway. Although it’s a bit thirsty, the performance is absolutely worth it. Regular maintenance is key—changing the oil every six months helps extend the engine’s lifespan and avoids costly repairs down the line.

I've been driving an Audi S7 for two years now, with a 4.0-liter engine. To be honest, the daily commute fuel consumption is a bit high, getting around 400 kilometers per tank in the city, but it's more economical on the highway. The engine performance is excellent, with quick throttle response, making it comfortable even in traffic jams during commutes. The space design is quite practical, with enough room for three adults in the back without feeling cramped, and the trunk is convenient for travel luggage. The downside is that maintenance costs are slightly expensive, requiring a bigger budget each year, especially since V8 parts aren't cheap to replace. The safety system is solid, with multiple airbags and automatic emergency braking to prevent accidents. Overall, if you're looking for a combination of power and practicality, this car is a great fit.

The Audi S7 has a displacement of 4.0 liters and uses a V8 engine with twin-turbo technology, typically delivering around 450 horsepower. This car is considered a high-performance representative in the Audi lineup, with ample power, quick acceleration, and a smooth driving experience. Compared to other luxury sedans, the S7's displacement is moderate—not as aggressive as a supercar, but still exhilarating enough for daily driving. During maintenance, it's important to regularly check the cooling system to prevent engine overheating. Additionally, the space layout is well-designed, with a large trunk capacity, making it suitable for family trips. Fuel consumption is reasonably controlled, averaging around 10 liters per 100 km.

From my driving experience, the Audi S7 with a 4.0-liter displacement has a well-tuned powertrain, delivering strong horsepower and even torque output, ensuring smooth starts without excessive shaking. Compared to similarly priced cars like the BMW M550i with a 4.4-liter engine, the S7 is slightly more fuel-efficient, with comparable acceleration performance, and its quattro all-wheel drive provides better stability in corners. I recommend checking the engine history when considering a used car to avoid high maintenance costs associated with the displacement. It offers comfortable daily driving with supportive seats that prevent fatigue on long trips. Safety features include automatic parking and lane-keeping assist, making it reliable to drive even in rainy or foggy conditions.
