VWs 1.4L I4 with Cylinder Deactivation

Polo BlueGT?s Active Cylinder Management (ACT) can reduces fuel consumption by up to 10% at low loads. 2013 Polo BlueGT - $24,278 USD (includes VAT) at today?s exchange rates and a 52.3 mpgUS combined on the NEDC. Maybe 42 mpgUS combined on our own EPA? The Volkswagen Polo in its many forms has always been a fuel miser and while some variants were nothing more than science experiments released to the European public, they were all hyper efficient for their day.
