Whether you would consider this "last ditch" or not is debatable, but this is definitely a marketing program. And why not? The old saying "Win on Sunday, sell on Monday" has been around for as long as they've been racing (in the U.S. anyway). Think about the marques that currently feature some sort of bragging rights about their race program (Audi, Mazda, Acura, Toyota and then there's Chevrolet, Ford, Dodge and even Cadillac and Pontiac andn more). Actually, now that I think about it, VW may have been one of the very few NOT to promote racing as part of its overall marketing strategy. And the strange-ness of that is that they've been racing and winning for years in Europe!
Although the program ain't perfect, it is a serious step forward for VW racers. Having the "factory" pay attention to ALL of us racers (National AND Regional) is major. And the way they set it up, they will reward race wins and overall championships. Good for bragging rights for them, great for us that race VW's.
And if it helps them sell Rabbits, GTi's, Jettas, etc - then it worked. If not, at least we racers had a little help for a time!
