What are the differences between the Audi RS4 and S4?
3 Answers
The differences between the Audi S4 and RS4 are as follows: 1. Different positioning: The Audi S4 is a performance model; the Audi RS4 is a high-performance model. 2. Different models and sizes: (1) The Audi S4 is a sedan with dimensions of 4770*1847*1404 mm, a wheelbase of 2825 mm, and a trunk capacity of 480L; (2) The Audi RS4 is a station wagon with dimensions of 4782*1866*1437 mm, a wheelbase of 2826 mm, and a trunk capacity of 505L. 3. Different power: (1) The Audi S4 is equipped with a 3.0T V6 turbocharged engine, producing a maximum horsepower of 354 hp and a peak torque of 500 Nm, with an official 0-100 km/h acceleration time of 4.7 seconds; (2) The Audi RS4 is equipped with a 2.9T V6 twin-turbocharged engine, producing a maximum horsepower of 450 hp and a peak torque of 600 Nm, with an official 0-100 km/h acceleration time of 4.1 seconds. 4. Different engine technologies: (1) The Audi RS4 features a high-speed engine first used in Audi's mass-produced models, with a maximum engine speed of 8,250 rpm. 90% of the engine torque can be continuously output within the speed range of 2,250 to 7,600 rpm, allowing the model to provide sufficient traction over a wider range. Additionally, with the FSI technology, the Audi RS4 can more effectively mix fuel and air, delivering even more powerful performance. (2) On the other hand, the Audi S4's low-pressure turbocharged engine excels in explosive power. Although its horsepower output is relatively conservative, it performs exceptionally well in low-speed torque. In some domestic acceleration competitions, an Audi S4 with a stage 1 tune can compete head-to-head with an Audi RS4.
I've driven both the Audi S4 and RS4, and I feel the S4 is more balanced for daily use. With around 349 horsepower and slightly softer suspension tuning, it doesn't feel too bumpy during the commute, and it's more fuel-efficient, making it suitable for family outings. The RS4, however, is different. It boasts about 450 horsepower, accelerates much faster from 0 to 100, and delivers an incredibly strong push-back feeling. Its design is also more flamboyant, with a wider front face and aggressive wheels, turning heads when parked on the roadside. But the RS4 is significantly more expensive, with costly maintenance and repair parts. If you're a thrill-seeking enthusiast who occasionally hits the track, then splurging on the RS4 is absolutely worth it. Otherwise, the S4 offers better value for money, and the money saved can go towards a new set of tires or a road trip.
As a car performance enthusiast, I'm most concerned about the power difference between the RS4 and S4. The S4 is equipped with a 3.0-liter V6 engine, delivering approximately 349 horsepower, which provides quick acceleration that's more than adequate. The RS4 upgrades to a 2.9-liter twin-turbo V6, unleashing around 450 horsepower, capable of accelerating from 0 to 100 km/h in just 3.9 seconds—the instant thrust is particularly exhilarating. Both models come with the quattro all-wheel-drive system, but the RS4 is tuned more aggressively, offering better cornering stability, a louder exhaust note, and greater potential for modifications. However, the RS4 has higher fuel consumption and a significantly higher price tag. If you're all about the thrill of speed, the extra cost is worth it. For daily driving, the S4 offers more comfortable handling, being both hassle-free and more affordable.
