Economical: Only 5.1L/100km
5.1 litres of diesel per hundred kilometres – the Passat BlueMotion is redefining the status quo of its class in fuel economy. The figure is just 0.1 litres more on the Passat Variant. The Passat BlueMotion, which is always equipped with a diesel particulate filter and 77 kW strong TDI diesel engine, achieves fuel economy values that were once exclusively attainable only by much smaller vehicles.

Clean: CO2 emissions as low as 136g/km
Low CO2 emissions. Once again a reduction in CO2 emissions was achieved: 136 g/km is the value for the sedan, and 137 g/km for the Variant.

Efficient TDI diesel engine:
The 1.9 TDI diesel engine of the Passat BlueMotion develops its maximum torque of 250 Nm at 1,900 rpm. To achieve this especially economical level of performance Volkswagen engineers tuned a wide variety of parameters. A software modification to the engine controller, for example, reduced idling speed from 830 to 730 rpm. The controller also sends gear recommendations to the "Multifunctional Display Plus". The display shows the driver which of the five forward gears is currently the correct gear for economical propulsion.

Modified gear ratios.
An important factor in fuel economy is gear ratio. Compared to the base model, the ratios were lengthened slightly in gears three through five. Because of its powerful torque, the Passat BlueMotion still moves rapidly. The modified gear ratios hardly have any effect on the intermediate bursts of acceleration in the first four gears that are important for safe passing maneuvers on highways. The sedan sprints to 100 km/h in 12.1 seconds, and the Variant in 12.4 seconds.

Low air drag:
Not only was the gearing reworked. Take aerodynamics, for example: Here engineers optimized the air flow behavior of the radiator grille and underbody. These modifications succeeded in reducing the air drag coefficient by more than twelve percent to cW 0.273 (sedan) and cW 0.275 (Variant).

Low rolling resistance:
The Passat BlueMotion has a number of additional modifications to offer in the chassis area. To improve aerodynamics even further, the car stands somewhat lower to the ground; it was lowered 15 millimeters in front, and eight in the rear. Furthermore, the so-called "best-in-class energy tires" from Continental provide for lower rolling resistance. They are 205/55 R16 91H in size and with normal loading they are driven with air pressure increased by 0.4 bar.
