With all the technology and funds that VW has access to, why would they want to recess in technology and race in Nascar? VAG (Volkswagen Auto Group) is now the worlds largest manufacturer, and owns quite a list of names including Porsche, Audi, Bentley, Lamborghini, Bugatti, and more. With those manufacturers under the head of VW, you'd think they would go for F-1, or even one of the LeMans series. But if they just want to get their name out there in the US, Nascar is the only way to go... as much as I hate to say it. I very much dislike Nascar.
Nascar is more or less a spec race series, meaning all the cars and components are basically the same. Why not open it up like the old days and let them duke it out. Then Nascar might be interesting to me. Oh, and throw in some off camber chicanes and right hand turns too. Oh, and I drive a VW.

My specs... A hard drive, motherboard, graphics card, some memory, a keyboard, mouse, and monitor - in other words, nothing special.
