The G6 is getting there with these improvements, but if GM wants to truely compete with the foreign autos the G6 needs further refinement in power, efficiency and weight. It's good to see the 3.6L V6 for 2007, but why in the world couldn't they mate it with a 6-spd manual? Is the 3.6L V6 all aluminum and will that G6 be as heavy as the present GTP?
