Now I thought my ’06 TDi was all that and a ball of wax, but these new Clean Diesels seem to be everything I wanted and then some. The New York Times is arguably not renowned for its car reviews, but they, along with what seems like everyone who‘s test-driven the new ’09 Clean Diesel model, loves it. Okay, so the last linked review was (unfortunately) objective in its view, but sufficient time riding in a TDi — either a new one or an older one that’s been tricked out with a RocketChip upgrade such as mine — should erase any concerns one may have. Cleaner emissions with Prius-crushing highway mileage. It doesn’t get much better than this. But wait! It does: the new Clean Diesels are eligible for a federal tax credit. That should help with the long-term cost breakdown.
