June 5th, 2010 · No Comments

The first member of the current Audi V family of engines was the 3.2-liter V6 FSI engine. Special features of the Audi V-engine family are the 90-degree angle between the cylinder banks and the 90 mm spacing between the cylinders. The 4.2-liter V8 FSI engine is also a member of this family. It is available in two versions – a comfort-oriented version (used for the first time in the Audi Q7) and a sporty high-revving version for the new RS4. A 5.2L V10 FSI will also be available in the near future. The 4.2-liter V8 FSI engine is supplied in the new Audi Q7 and RS4. In the future, the engine will be used in the Audi A6 and A8.
The following main objectives were set for the development of the Audi Q7 engine:
– High specific engine power: ● 350 bhp out of 4.2 liters (15 bhp more than MPI engines) – High torque: 325 lb. ft. out of 4.2 liters – Reduction of fuel consumption by approximately 5 % (at 2000 rpm and 2 bar) – Short and compact design – Modular engine concept based on the V6 FSI engine for V8 and V10 FSI – High idling quality – High standard of comfort with regard to acoustics and running quality – Low engine weight – Off-road capability of Audi Q7 engine.
