Was interested in pricing comparisons too, however GM Canada's web site is on holidays it seems. I can't price a 2016 Malibu or a 2016 Camaro. The US GM site has no problem providing both.
Speaking from experience, the GM 2.0 turbo, when the HP ratings are around 250 HP like in this Malibu and my car, it has great torque from low revs, no lag. When it has higher HP ratings, the ATS for example which I think without looking is around 270, then its not so smooth and there is a bit of lag.
