Active Cylinder Technology (ACT)

BlueGT is a new series of petrol engines that has been developed. The engine range consists of 1.0, 1.2 and 1.4 litre engines. The outstanding technical aspect of the new engines is the active cylinder Technology (ACT). Volkswagen is the first carmaker to implement this fuel saving cylinder deactivation technology on four-cylinder engines, as it was previously the preserve of large eight or 12 cylinder engines. Shutting down the second and third cylinders during low and medium load states reduces fuel consumption in the EU driving cycle by about 0.4 l/100 km.
