Not sure if you are asking about the car or the engine!
However, the good small diesel engines are common
rail engines, which apparently allows for better control
over the fuel injection than conventional injectors
- or so Wikipedia says.

My Laguna has one and drives pretty much like a petrol
car (and will cruise all to easily at 90mph in 6th!),
unlike the truely awful diesel I had quite a few years
back. The Laguna also has an 18,000 mile service interval,
and get 45mpg - that's imperial miles & gallons of
course.
