I'll admit that these days the only thing I use the IMA motor for is frequent restarting after FAS. Still get great fuel economy because of the light weight, very efficient gas engine, and aerodynamics. The IMA is still worth it because it allows the gas engine to be 2/3 the size it otherwise would be and use the IMA motor for the limited times you accelerate, move from a complete stop....unless you are a gearhead - then the driver and IMA system is a mismatch.
The BAS system GM introduced has to be one of the worst hybrid implementations.
