"Audi News" website claims new A8 will be presented in June. It also showcases A1 and A7 SUV!?
 

Here's a link to a site that claims the new 8 will be shown to the public in June. It also has pics of other (upcoming?!) models such as an A1 and an A7 SUV (doesn't look very convincing). Look for this in the section called "Study models". There's an interesting drawing for an A4 coupe as well. It shows what I believe are called suicide-doors (the rear one being small): rear side doors hinged opposite to the front side doors.

This site is very basic and simple, containing more pics than information.<ul><li><a href="http://195.241.99.177/news_index.html">Audi News</a></li></ul>

4.2 V8's to lose their belt driven cams :-)
 

.
and an end to expensive periodic maintenance.

"This autumn, the new 4.2 litre V8 "chain-driven engine" celebrates its premiere in the Audi allroad quattro 4.2. In this engine, the toothed belt has been replaced with a timing chain, as a result of which the camshaft drive has been relocated to the rear of the engine. This arrangement means that the chain is subjected to less strain and a duplex chain can therefore be dispensed with. Thanks to the removal of the toothed belt, the already compact V8 is shortened by a further 52 millimetres. This power plant will also be fitted in the S4, which will be presented at the end of the year, and will then gradually replace the toothed belt-driven engine."
