>then make the A8 wider

Making the A8 wide enough to accomodate the Lamborghini V12 would've been
excessive. Beyond that, I'm not sure what you don't understand about the
production limitations of the Lambo V12. It would've required millions of
dollars to re-tool for that. Don't forget, Audi had already incurred the cost
of adapting manufacturing lines for the W12. They introduced the engine in 2001
in the previous A8.

It's not a VW. The A8 and Pheaton share only minimal suspension components.
