Two Sedans with some similarities, but otherwise different in most aspects such as the model year, starting price, horsepower, and fuel economy. First of all, there is a notable difference in the starting price of the 2016 Acura TLX, which is $7,400 less than the base MSRP of the 2013 Cadillac CTS, which is three model years older. And finally, the 2013 CTS has a more powerful engine and gets 5 mpg less than the 2016 TLX. Among similarities are the body structure, market segment, ground shadow size, height, and maximum occupancy.
