100mpg from diesel hatchback??

Hi

I'm from England and have recently developed a strong interest in FE. With diesel costing $12 per gallon equivalent, I am in the process of buying a small VW 1.4 turbo diesel hatchback, see spec here-

This car can obtain 78.5 mpg on country roads/ freeways, and this is where I do 95% of my driving . So, how easy/ difficult will it be to get 100mpg- a 30% improvement over manufacturers spec?

What changes have you guys had to make to your cars to get a 30% improvement in FE? I take it simply maintaining speed at 60mph ( our speed limit on country/ rural roads), coasting with engine off, inflating tires to slightly above tyre spec will not do the job?

A chip improves power by 30% but also torque by 40% so I will certianly be doing this, and it only costs $70

I would be smug as a bug in a rug if I could get 100mpg from a run of the mill diesel hatchback, it will be my project for the near future
