When it comes to the fuel economy, the star of the show is the new ML 250 BlueTec. Mercedes-Benz’s 2.2-litre turbodiesel has been seen in many Mercedes model series and now it has found its way to the new ML. The four-cylinder diesel sure is economical. The combined fuel consumption of the ML 250 BlueTec is just 6,0 l/100km. The CO2 emissions are only 158 g/km. These are pretty remarkably numbers for a big SUV with a four-wheel drive. On the test drive, the average fuel consumption was little over seven litres per hundred kilometres.
