GM needs no more than three V6 engines:

1.A really smooth nice one for the cars very similar to the 3.6L engine line that can be tuned differently for each application..Like the CTS gets the DI engine, the SUVs get more torque bias, etc.

2.A powerful, rugged, fuel efficient V6 for the trucks. This was supposed to be the Atlas lineup, but the T900s ended up using modified T800 frames instead of new ones and couldn't fit the long engine.

3.A fuel efficient V6 diesel engine that can be used for small/midsize trucks and SUVs and for midsize and large sedans.
