The current December issue of the magazine carries a report of the test drive. The turbo-diesel Smart travelled 1,000 kilometres from Rome to Salzburg on a single tank of fuel to see whether the stated standard consumption of just 3.3 litres per 100 kilometres could really be achieved.

The route chosen largely consisted of motorways, but there were also detours and traffic jams because of roadworks, long uphill stretches and city traffic in Rome, Bolzano and Salzburg.

The result: the Smart Fortwo CDI travelled the 1,000 km on a single tank of fuel. This corresponds to average consumption of just 3.3 litres per 100 kilometres i.e. the standard consumption.

According to Quattroruote this makes the Smart Fortwo CDI the vehicle with the lowest average consumption that the magazine has ever tested in the history of its road tests.

With standard consumption of just 3.3 litres per 100 kilometres and CO2 emissions of just 88 grammes per kilometre the Smart Fortwo CDI is the production vehicle with the lowest consumption and the lowest carbon dioxide emissions. For customers this means that at present there is no more economical and climate-friendly car than the Smart Fortwo CDI.
