While the Passat BlueMotion II may not be at the sharp end of the rankings, it’s certainly in the thick of things at 57.3mpg (4.1L/100km), and it’s the most efficient Passat ever, according to Volkswagen.
The new Passat is also the first to meet the Euro-6 emissions standard, which aren’t due to come into play until 2014, putting the BlueMotion II well ahead of the game. Carbon dioxide emissions sit at 109g/km, about 5g/km below the car that will be going into production next year, based on this concept. VW gets to these very low emissions figures by combining its BlueTDI technology with the BlueMotion line of efficiency enhancements.
