Honda actually tried this with the Acura RDX and failed miserably. That engine was laggy and got lousy mileage. That's why the 2013 RDX is going V6 only. Except Mazda (Speed 3 and CX-7). The Sonata 2.0T engine is very good. The rest of the car is just OK. The current Accord is not all that great. The I4 engines are too loud, the ride is a bit too firm, and the ergonomics are less than ideal. I'm hoping the 2013 redesign addresses these issues.
