In the low-end diesel car market, yes, it's pretty much been their's for decades. They've had their headaches to deal with here (EPA), but as I've said before..... overall their strategy is a no-brainer in the N. American market - it's just good business to operate in a market where you have virtually no competition. One characteristic I noticed in smart tech-sector companies: they compete with themselves, before somebody else does it for them - it's a key strategy for staying on top. Like aczlan commented, some of the new DI gas motors are getting pretty good - how long before some company bolts one of the latest gen engines onto a hybrid drivetrain ? As we see all the time on here, there's a knee-jerk reaction from many people in the USA concerning diesel fuel price. VW is doing well in the market with their diesels. My interests aside, I believe that a diesel-hybrid would open up a new buyer segment for VW - partly because it tilts the balance of the skewed diesel pricing in the USA, but also because of the heavy general marketing push here on hybrids....
