The 2011 Frankfurt Motor Show will play host to four new high-performance Audi S models sharing one remarkable new eight-cylinder engine which enables them to counterbalance outputs of up to 520PS with the potential for up to 29mpg*. The new bi-turbo V8, incorporating cylinder on demand technology and a host of other advances, replaces the naturally aspirated V10 FSI engine in the all-new S6, S6 Avant and S8 models, and in the process improves economy by as much as 25 per cent. It is also at the heart of a completely new addition to the S quattro Series – the new S7 Sportback.
The S6 and S6 Avant, S7 Sportback and S8 share a new V8 bi-turbo petrol engine featuring cylinder on demand technology, the S6 models and S7 Sportback taking the unit in 420PS form and the S8 using a 520PS version.
