2018 Mercedes-Benz S-Class vs 2018 Cadillac CT6 Sedan

2018 S-Class vs 2018 Cadillac CT6 Sedan

It can be difficult to navigate the luxury automobile segment with so many options to choose from. To help narrow things down, Mercedes-Benz of Arrowhead created a simple 2018 Mercedes-Benz S-Class vs 2018 Cadillac CT6 Sedan comparison. 

The most notable difference between the two models is the starting price--the Cadillac CT6's top trim level costs just a few thousand dollars less than the S-Class Sedan's base trim level. This stark price difference indicates that, even as a base model, the S-Class has much more to offer for every passenger. Both models offer two engine options, but both S-Class engines outperform the CT6's engine options. The sedans keep their power in check with impressive fuel economy ratings and top out at 155 MPH.
