Hey guys,
Sorry to jump in out of no-where..but I test drove a few Focus TDCI's over the weekend, and found the same thing...you really need to adjust your driving style to take advantage of the engine's sweet spots in the rev ranges.
The new diesel engines are great, in my opinion it actually felt alot more fun and responsive to drive than the diesel Golfs i drove.
Now I am very happy..ended up purchasing a Focus TDCI privately with 2,600 kms on it
I cant wait to start collect it at the end of Jan to start driving it !!
