Re: '11 vs '12 V6??
He is pretty much right about the steering
Less drag on the engine at a near idle speed will make it more efficient, if these cars had a traditional clutch fan assembly the MPG would drop by 3mpg.
and yes it is confirmed my Mom's late '11 has a power steering pump and my early '12 had the electro hydralic steering.
There is no real difference if feel to me but as the cars break in we will see both have less the 2000 miles on them.
