Well, I have never experienced it jumping three gears and havent heard anyone complain about it either. The Focus has plenty of torque to quickly pull you intothe optimal power band without having to downshift a bunch. Lower the rpms when taking it easy the better the fuel economy is going to be. Anyway, powershift has recieved significant updates over the past year. Imo, powershift never really had a problem, besides it could of been a little faster with shifts, it was really all public perception. Being used to smooth, slow shifting, lathargic, no feedback, torque converter automatics, people thought something was wrong when theyd feel their automatic shifting, especially at low gears (you know, just like manual trans). It wasnt that these cars were leaving people stranded at the side of the road, or blowing up, or chewing up gears, it was all really public opinion on how an automatic should be. And I think its kind of ridiculous for the media to be ripping down Fords credibilty and quality and listing it as something terrible (Consumer Reports) when there really wasnt anything seriously wring with it.
But to answer your question, 2013 should be just fine, I believe they smoothed out the shifts some and made them a tad quicker.
