Pretty much all the major manufacturers in Europe have a common rail turbo
diesel.  Of the top of my head:

Ford - TDCi
Peugeot/Citroen - Hdi
Opel/Vauxhall - CDTi
Fiat - JTD
Alfa Romeo - JTD
BMW have a fantastic 3 litre 6 cylinder common rail turbo diesel that is as
quick as the 3 litre petrol (gas) engined car. One of the best automotive
diesel engines ever made.

One of the big advantages is that the diesel in not injected all at once.
By injecting a small amount of diesel before the main charge, the combustion
process can be made more efficient and the diesel noise is considerably
reduced.

A bit of information and a few links on this page:
