Audi's Johan de Nysschen:
We're going to expand our product portfolio. We'll have at least one more SUV, possibly two. We'll have more sports cars, something between the TT, at the bottom, and the new R8.
The fact that we're moving away from platforms to modular (product designs) gives us lots of flexibility, and we can do a lot more derivatives. If you look at the Road Jet concept at the (2006) Detroit auto show, which was a slightly elevated car with a small footprint, it gives you an idea of what we mean about more derivatives. And then we have to look at drivetrains, like diesels, where we have to see an expansion, as well.'
