Volkswagen has officially unveiled a new three-cylinder turbodiesel engine at the annual Vienna Motor Symposium. The new 1.2-liter engine features the same common-rail fuel injection systems and basic architecture as VW's 1.6-liter and 2.0-liter inline fours.

The new 3-cylinder produces 74 horsepower and 133 pound-feet of torque at just 2,000 rpm. When VW unveiled the new Polo at the 2009 Geneva Motor Show ,a concept version of the next-generation BlueMotion model was shown with this engine. The three cylinder Polo is expected to be rated at 71.3 miles per gallon (U.S.) and 87 grams / kilometer of CO2 emissions on the EU combined test cycle. The new 1.2-liter Polo BlueMotion should debut later this year.
