works under the hood of the sedan and wagon Insignia OPC with a 325 hp V6 with 2.8 liters and a turbo Twins Croll. In this special form of the turbocharger, the exhaust gases of the two cylinder banks are merged until just before the turbine. This is to keep the energy loss through the small loader. The OPC unit is derived from the 260-hp engine, there is in the Insignia Sport and Cosmo. What there will not jump into the cylinder, but classically injected into the intake manifold. Unlike the 260-hp versions, which are either to buy it with automatic transmission, the OPC is always delivered with six-speed circuit.


The powerful motor delivers 435 Newton-meter that can be felt on every meter. A technical curiosity is that the maximum torque is applied at the same speed as the maximum power. From 2,000 to about 4,200 rpm it to 400 Newton meters, then makes a detour curve upwards and reaches 5250 rpm the maximum value. Thus, in every situation more than enough power available.
