    I drove both the turbo 2.8 and the 3.6 back to back, the important thing is where the torque is applied in the RPM range. The 3.6 is low in the RPM range so it feel a lot stronger. Go drive a 3.6 you will see how much better this engine works in the heavy car then the fast spinning 2.8, you will be very suprised at the low level of effort the 3.6 takes to do the same job.

    good point... max torque may not mean anything if you never really push the car to those extremes

    Not to sound like a broken record but the '12 SRX feels about as fast as my '09 SRX V8 and that car had 50 lb ft. more tq. than the '12.
    GM did a REALLY good job with the new motor. It is noticeably stronger, quicker revving and smoother than the previous 3.6Ls.
    max tq. comes on over 2000 rpms than the old V6 and I would imagine that the tq is flatter also.

    There are starting to be a few Camaros with the 3.6L LFX on the streets and they are saying it pulls really well. Of course it is almost 600lbs lighter also.

    The chrome tech wheels increased from $450 to $495.
    Note that 2012 Prices changed differently for all trim levels and drive types. The Performance/Premium AWD's are the only ones that technically had a "reduction" from their end of year 2011 pricing. The other's are all a $600-$700 increase.
    Autos.MSN.com has the 2012 pricing up.

    The 2.8 hits it's max torque at a lower rpm compared to the 3.6

    right, but how many people really wind up the car to access the max torque?

    i'd like to see the two torque curves on the same graph

    The max torque is very low on the rpm range. The 2.8 is around 1850 rpm, and the 3.6 is around 2400 rpm. Maximum horsepower is high on the rpm range (2.8 max HP @ around 5500, 3.6 max HP @ around 6800).

    I was looking at a 2012 (3.6) today, and I noticed that there was a ECO button on the console to the right of the shifter. Anyone know what it does?

    It's great for freeway driving, not so good for around town.

    I agree it is suppose to help you out better for extra MPGs when you are in highway driving mode.

    However, I have left mine on since I bought it and I have never turned it off yet. With it on the 3.6L still pulls tremendous torque and power ... hmmm I will have to do some spirited driving with it on and off to compare the difference.
