In addition to impressive data, the engine of Audi's new RS4 also has the following highlights: 1. It is the first high-speed engine used in Audi's mass production version, with a maximum speed of 8250 rpm. The displacement of 2.4163 milliliters has enabled the new RS4 engine to reach a level of 100 horsepower per liter, which is a proud increase in power among mass-produced models. 3.90% of the engine torque can be continuously output within the speed range of 2250 to 7600 rpm. This allows the vehicle to provide sufficient traction over a wider range, allowing the driver to drive in a relaxed state without the need for frequent gear changes. 4. FSI technology, this gasoline direct injection technology ensures more effective fuel air mixing and outputs more powerful power. The significant improvement in corresponding power performance is a good proof of this.
