Is there anything that might better the Mirage MT fuel economy in the real world?

[Teasmade]

In Europe there are a few little cars, that do as good as the Space Star 1.2. But the Space Star 1.0 is the most economic conventional gasoline car that can be bought in Europe today.

Honda Insight: 3,8 l/100 km
Daihatsu Cuore: 4,8 l/100 km
Toyota Yaris Hybrid: 4,8 l/100 km
Space Star 1.0: 4,9 l/100 km
Nissan Pixo: 5,1 l/100 km
Space Star 1.2: 5,1 l/100 km

To add to this - In Europe the Suzuki Celerio is comparable to the 1.2 Mirage in terms of MPG, but in the summer Suzuki are launching the 'Dualjet' version - essentially a high-compression engine with two injectors per cylinder to keep knock under control. More about the engine here including an informative video:

The official figures are as follows (imperial MPG):

Urban: 68.9
Extra Urban: 83
Combined: 78.4

Thanx but I really meant to exclude hybrids (except if comparable in price).
