The German car maker Volkswagen put the spotlight on its new 3-cylinder 1.2-liter TDI diesel engine during the 31^st Vienna Motor Symposium held recently. This was the same engine applied in the Polo BlueMotion, whose fuel consumption is as low as 3.3 liters per 100 kilometers.

This engine is a derivative of the 1.6 L 4-cylinder TDI engine on the new Passat and Golf BlueMotion. Compared to the bigger TDI engine, the 1.2-liter TDI is also notable quiet. This is because it uses the latest generation of Volkswagen’s common rail injection.

Despite of the engine’s relatively small displacement, the engine 1.2-liter TDI diesel engine can still 180 Nm of torque. According to reports, the engine paired with several other modifications on the new BlueMotion contributed up to 0.9 L/100km of fuel savings.

This makes up for about 22% reduction of the vehicle’s fuel consumption. The previous Polo BlueMotion consumed 4.2 L/100km, while the new one burned only 3.3 liters over the same distance. The CO2 emission in the new Polo BlueMotion was also reduced by 22g/km.

According to the Volkswagen’s press release, the engine was designed to produce dynamic engine performance despite the reduced displacement. The engine is also designed to give the most acoustic comfort, with an overall reduced weight, without, of course, sacrificing the engine’s ability to keep its temperatures stable.

Aside from the compact and lightweight features of the new eco-friendly engine, it also boasts of reduced power loss and friction. Professor Dr. Wolfgang Steiger, the Head of Future Technologies in Group Communications, stressed that future long distance and freight transportation will be depending on internal combustion engines like the Volkswagen’s new 1.2L TDI.
