A have read a lot people complain about the 2.3 motors in these vans. I have found that in automatic mode it can indeed be sluggish sometimes when it is weighed down with a heavy load. In sports mode though it is more than adequate. I pretty much exclusively drive my 2010 5 in manual sports mode. Learning when to shift between gears and where the most torque is in between the power band takes sometime to get use to, but when you do , the difference is remarkable. I feel the computer doesn't do anything to maximize the full potential that the engine does have, it is always seeking to hit the highest gear possible to maximize fuel efficiency, regardless of what the driver wants to do. I recently took my 5 to the blueridge mountains and going over several mountains with 2 adults, 2 kids, and our luggage, using the soprts mode, the 5 handled the moutains with no problem, nor did it feel sluggish ( granted my rpms where around 3000 to 3500 going up some of those mountains). Even with my rpms hovering around 3000 to 3500 for those ascends up, I still averaged 25 mpg's. I think the problem lies more with the way the computer controls the auto tranny, than with the engine( not saying that 15hp or 20hp more would be nice). I have switch from auto to sports mode and the computer had the it in 5th gear at 40mphs. There is no torque whatsoever from that engine in 5th gear at 40mphs. 5th gear should be hit at 50mphs or 60mphs.
