Two SUVs with some similarities, but otherwise different in most aspects such as the model year, starting price, horsepower, and fuel economy. First of all, the 2014 Infiniti QX80 is priced $10,270 lower compared to the base MSRP of the 2016 Cadillac Escalade, which is newer by two model years. And finally, a bigger engine usually means less mpg. But the 2016 Escalade has a more powerful engine and it gets 1 more mpg than the 2014 QX80. Among similarities are the body structure, market segment, ground shadow size, height, and maximum occupancy.
