The modern electronically controlled common-rail diesel engines are also far superior in both power and fuel economy compared to the old school diesels such as that in the Mitsi.
If you want it to drive like a car they are what you need.

The van by comparison is a truck and only gets about 12-13L/100km because it weighs more than 2000kg empty and has the aerodynamics of a barn door..

The plus side is its simplicity and price, you can pick them up for 6-9k.
