My sister has one of the pre-TDCI turbo diesels and I believe it's only 100PS rather than 115PS found on the TDCI ones.
A friend of mine had a TDCI Focus and we used to work together and often give me a lift, up to 90 it was bloody rapid and was really really good on fuel especially with motorway mileage
I had a 1.6 Zetec Focus myself and that was pretty good on fuel and was much quicker than an equivalent 1.6 Zetec Escort - big big fuel tanks on them compared to Escorts as well meaning less refuelling during the weekly commutes!
Cheers,
Andy
