That's the million dollar question in the fuel economy test. Two middle-aged men, Dom Jolly and Rufus Hound made a trip from the Volvo UK HQ in Marlow, Buckinghamshire to Milano, Italy and back again. Why? It's a journey about friendship and fuel economy, primarily the latter.
The car used is a 2009 Volvo V70 DRIVe which is powered by a 1.6 litre turbo-charged diesel engine, producing 109PS. Fuel economy is rated at 57.7mpg combined with a CO2 output of 129g/km. Prices start at £23,245.
