I was curious about the 2.4 L GM engine, could it get good economy in other vehicles? I saw it had variable valve timing which if done well essentially makes for a variable displacement engine.
Then I looked up the GM's with it and see it does pretty awful. The closest car would be the Solstice which gets 19/21/25 MPG......the best is in a Pontiac G6 getting 22/26/33. Ugh.
