When the second-generation Smart ForTwo entered production earlier this year, its EU mileage ratings put it at the top of the heap for internal combustion engined cars by a pretty wide margin. On the EU combined cycle the diesel version was rated at 71.3 mpg (US) with CO2 emissions of only 88 g/km. The Italian magazine Quattroruote decided to see if that was achievable in the real world. They laid out a 1,000 km route consisting of highways, traffic jams, mountain roads and urban settings in Rome, Balzano and Salzburg. The bottom line is that they consumed 33 L of diesel to cover the distance, matching the official ratings.
On a long journey of 1,000 km the Italian car magazine "Quattroruote" measured the fuel consumption of the smart fortwo cdi and confirmed the standard consumption of 3.3 litres per 100 kilometres.
The current December issue of the magazine carries a report of the test drive. The smart travelled 1,000 kilometres from Rome to Salzburgon 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 grams 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.
