Two Sedans with some similarities, but otherwise different in most aspects such as the model year, horsepower, starting price, fuel economy, and ground shadow size. First of all, there is a notable difference in the starting price of the 2013 Cadillac ATS, which is $5,655 less than the base MSRP of the 2016 Hyundai Genesis, which is three model years newer. Also, the 2016 Genesis has a more powerful engine and gets 3.6 mpg less than the 2013 ATS. And finally, the ATS has a slightly smaller body than the Genesis. Among similarities are the body structure, market segment, height, and maximum occupancy.
