Went in and drove the Saab 1.9CDTTI today. The CDTTI had a slightly better pick up low down as one would expect but by 2000rpm it just felt wet. I tested it using my little box and ran it around for quite a while, it would definatly need tuning up to even keep up with mine. Not impressed I'm afraid but as a base to start from which is what I was looking at, it has potential. The pull noticably died off at around 4000rpm as with the CDTI so there should be masses of room for squeezing out more up there. That tiny little turbo that works by itself until 1800rpm is not working anything like hard enough, I'll be wipping that thing into life when I get one.
All in all it wasn't a bad ride, the car happily plodded along at low revs with no complaint, which will be good for economy. It's a definate improvement over the 150PS version of this engine, much more refined but still not enough.
