In 2010 Audi triggered the second evolutionary phase of the V6 TDI. Many of the components – including the crankshaft, the conrods, the pistons and the cylinder heads – were new. The crankcase was made 6 kilograms lighter, and the complete engine weighed 25 kilograms less than its predecessor. Other innovations related to the internal friction, the thermo-management system, and the derestricted intake and exhaust tracts. The efficient new 3.0 TDI was launched in the A8 with 184 kW (250 hp) of power output and 550 Nm (405.66 lb ft) of torque, and its use was rapidly extended to many of the larger Audi models.
