Two SUVs with some similarities, but otherwise different in most aspects such as the starting price, horsepower, fuel economy, height, and maximum occupancy. First of all, the 2015 Kia Sorento is priced $10,150 lower compared to the base MSRP of the 2016 Infiniti QX50. Also, the 2016 QX50 has a more powerful engine and gets 1.5 mpg less than the 2015 Sorento. In addition, the QX50 is slightly shorter than the Sorento. And finally, you'll seat two more passengers in the Kia Sorento than in the Infiniti QX50. Among similarities are the body structure and ground shadow size.
