Special features of the current Audi vee engine family are the 90-degree included angle between the
cylinder banks and the spacing of 90 mm between the cylinders.
The first member of the family was the 3.2-litre V6 FSI engine. The 4.2-litre V8 FSI engine is also a member
of this family.
It is available in two versions - a comfort-oriented basic version (used for the first time in the Audi Q7) and
a sporty high-revving version for the new RS4. A V10 engine with 5.2 litres of displacement will also be
available.
Like the RS4 engine, the V8 in the Q7 has FSI direct injection, which – following five victories in the
Audi R8 Le Mans racing car – is now being introduced in a production eight-cylinder model.
The V8 was retuned for use in the Audi Q7. A fuller torque curve up to nominal speed and spontaneous
response – these are the characteristics of this new engine.
The engine excels not only with its dominant power output and high maximum torque. The resultant
driving performance is excellent, even in the face of tough competition.
