Down sizing is one of those subjects passing through the automotive world nowadays. Car makers are preparing smaller engines for new models. The next-gen Audi RS6 will suffer the same fate and will be dropping the 5.2L V10 for a smaller V8 and will add two turbochargers.
The rumour is coming from sources who told German publication AutoBlid. It adds up to another story we recently reported that the 2010 BMW M5 will be powered by the 4.4 litre twin-turbo V8. It is the same engine used in the new BMW X6 M and the BMW X5 M.
