Our resident CNG expert at SEAT challenged himself to drive the 615km trip from Barcelona to Madrid on just 20€ worth of fuel. Did he make it? You bet he did.The SEAT Leon ST TGI fuelled with CNG is more eco-friendly and ingeniously efficient, costing up to 50% less to run than a petrol car and 30% less than a diesel. It´s difficult to believe, but 20€ can go a long way – 615km to be precise. Find out more about the CNG Technology here: http://bit.ly/1CggeYm
