We recently did a trip of 795km with the new VW Polo. In mixed Autostrada and ordinary roads, including a little stop start traffic, it returned an astonishing mileage. 39.54 litres of petrol, less than a tank full for the whole trip, gave us 4.97 litres per 100km or just under 57 mpg (imperial). Being turbo petrol it gives excellent real would performance despite being only a 1.2 engine developing 90CV. It would be fantastic in a 4/4.
