Indeed, the consumption of the 2500 first series, or thirsty for 6 dell'Orto 40, or relations courts, is challenging.
In the city the 5 / 6 km by one liter is the norm. On the road, at speeds of traffic, the 9 are made quietly.
Same speech for the 2000, if not worse, equal relations, equal power, less power.
A deadly mix ....
Another speech for the 2500 ie. 8 in the city, largely on the highway 11.
Record of consumption is of course the TD.
Never below 10 by one liter in a city largely above 13 on the highway.
For the 2500 auto consumption, of course, worsens the order of 10%.
