How does the Sorento's fuel economy hold up in real world driving as Kia claims?

The Sorento boasts impressive fuel economy figures, particularly for the hybrid and plug in hybrid models according to Kia. But official ratings are not always what you get in the real world, and often by a considerable amount. Actual fuel economy may vary depending on driving style, terrain, climate, and vehicle load factors. Some owners say they’re getting numbers that are almost exactly or even better than the official ratings, while others are disappointed with falling short. The debate frequently revolves around whether the Sorento's fuel efficiency is truly competitive in its class, and whether the fuel savings that are possible are worth the Sorento's premium price over nonhybrid alternatives. And there's talk about whether or not the plug in hybrid is practical in areas where the charging infrastructure isn't that robust.
