The novel thermal management system, an innovation from Audi in many engines, lowers fuel consumption by up to 3 percent. Rather than being circulated, the coolant remains still during the warm-up phase so that the engine oil quickly reaches its operating temperature of between 80 and 120 degrees Celsius (between 176 and 248 degrees Fahrenheit). This significantly shortens the phase of greater frictional resistance due to viscous oil in the crankshaft drive and valve gear.
