Two SUVs with some similarities, but otherwise different in most aspects such as the model year, height, maximum occupancy, starting price, horsepower, fuel economy, and ground shadow size. First of all, there is a notable difference in the starting price of the 2016 Cadillac SRX, which is $4,155 less than the base MSRP of the 2013 GMC Yukon, which is three model years older. Also, the 2013 Yukon has a more powerful engine and gets 2.5 mpg less than the 2016 SRX. In addition, the SRX is both slightly smaller and significantly shorter than the Yukon. And finally, you'll seat three more passengers in the GMC Yukon than in the Cadillac SRX. Among similarities are the body structure and market segment.
