The Solstice 2.4 does need a 6 speed for sure. At 55MPH my revs are under 2,000 and I get 36.4 miles per gallon on the Highway.
If I bring the car up to 65MPH the revs go up to 2,500+ and I lose about 5 MPG. That's kinda sad.
My 08 Altima CVT 6 speed Automatic easily gets 38 MPG at 65 all day long. That extra gear brings down the revs big time.
G.M. could easily make the Solstice in a 6 speed, and it would help their overall MPG's
Just my
