The differences between S4 and RS4 are: 1. Different engines: The Audi S4 is equipped with a 3.0-liter supercharged TFSI direct injection engine, while the RS4 is equipped with an FSI gasoline direct injection V8 engine; 2. Different capacities: The luggage compartment capacity of the Audi S4 is 480L, while that of the RS4 is 1430L; 3. Different configurations: The central differential of the Audi S4 is a crown gear differential, while the central differential of the RS4 is a Torsen differential. Audi is a German luxury car brand, with its logo consisting of four interlocking rings. Its headquarters is located in Ingolstadt, Germany. The main models include A1, A3, A4, A5, A6, A7, A8, Q1, Q2, Q3, Q5, Q7, Q8, TT, R8, as well as the S and RS performance series.

I previously drove my friend's S4 and RS4, and the differences were quite noticeable. The S4 has plenty of power, equipped with a 3.0T V6 engine producing around 350 horsepower, accelerating from 0 to 100 km/h in just over 4 seconds. It's more than enough for city and highway commuting, with a more comfortable chassis that doesn't jolt too much over bumpy roads. The RS4, on the other hand, is much more aggressive, featuring a more advanced twin-turbo V6 engine with about 450 horsepower. The engine roars when starting, and acceleration is blistering fast, hitting 100 km/h in roughly 3.6 seconds. However, the suspension is stiffer, making it more thrilling on the track but noisier for daily driving. Overall, the S4 offers a balanced and cost-effective package, while the RS4 is tailored for performance enthusiasts seeking the extreme, though it comes with higher fuel consumption and may be too aggressive for practical everyday use.

As someone who values practicality, I find significant differences in the daily performance between the S4 and RS4. The S4 drives smoothly with quick yet not abrupt power response, and its fuel consumption is relatively friendly, averaging around 9-10 liters per 100 km in city driving. The interior is comfortable, and the space layout is reasonable, making it suitable for family use or versatile commuting. On the other hand, the RS4 boasts stronger power with about 450 horsepower, launching aggressively from the start. However, its seats are firmer, the body is more aggressive, and bumps like speed bumps are noticeably harsher. Fuel consumption rises to over 12 liters, and costs are higher, with parts being harder to find. If you don’t frequently hit the track or drive at high speeds, the S4 is more worry-free and cost-effective, while the RS4’s high-performance features may not be practical for the price.

I prefer driving details, and the S4 and RS4 feel different. Driving the S4 offers light steering and linear power output, making it easy to handle corners with stable control, suitable for beginners or daily drivers. The RS4's steering is more direct—it goes where you point it, with strong acceleration and explosive power, but comfort takes a hit. In terms of fuel consumption, the S4 averages about 9 liters, while the RS4 is close to 12 liters. Externally, the RS4 has more aggressive wheels and body kits. Price-wise, the S4 starts at 600,000 to 700,000, while the RS4 starts at 800,000 to 900,000. For general use, the S4 is recommended.

Considering cost-effectiveness, there's a significant price gap between the S4 and RS4. The entry-level S4 starts at over 600,000 yuan with decent performance, lower fuel consumption, and affordable . The RS4 costs 200,000-300,000 yuan more with higher horsepower but consumes more fuel and has expensive parts. The RS4 has slightly better resale value, but the initial investment is too high to be cost-effective. For average users, choosing the S4 is more economical and hassle-free.
