#3, it can meet current emissions standards but it is close to the limit, and with states now reassured in their ability to set their own standards, tougher than the Fed's, GM doesn't think they will be able to sell it in enough states.

#4, it meets or exceeds all performance goals and runs clean as hell, but will be so damn expensive GM doesn't think they can sell it.

#5, it is a super-engine that can do everything, but GM is planning to close the factories capable of producing the engine and projected volume of this motor alone isn't enough to justify keeping any of the factories open.

Wrong, Wrong, Wrong Wrong and Wrong. The engine was dropped because they were told to do so or moreso that the truck/SUV plants were the ones that should close. It was a trick engine...no exhaust manifolds and the turbo was in the center between the intake manifolds.

It was a 2010 calendar year complaint engine.

Its a damn shame.
