Car Magazine is proudly saying that it was right all along about the RS5, but as the pages of RS6.com's forum's alone show, there is considerable disagreement about various details, especially the engine, suggesting that Car is not as well informed as it thinks it is.
Car is still saying the RS5 will get a bi-turbo version of the 4.2 litre V8 whereas many other sources seem to think it is a better breathing version of the existing engine. Georg Kacher - Car's esteemed correspondent from the Fatherland seldom puts a foot wrong and is the voice behind Car's claim. He also writes for Germany's Auto Motor und Sport which has contradicted Car's claim by saying that the engine is a development of the existing unit.
So who's right?
I tend to think that Audi is conducting a rather clever but annoying campaign of deliberate disinformation. Separate sources from within Audi are communicating different 'off the record' details about the RS5. It'll make the actual reveal much more interesting.
