Scania trials spoiler claimed to cut truck fuel by two percent

Scania has begun tests of a rear air deflector, known as a boat-tail, said to reduce fuel consumption by up to two percent. The truck giant suggests that, if proven, that corresponds to an annual saving of 1,200 litres of fuel and three tonnes of CO2 emissions for a truck running 200,000km per year.
